First off let me say they were true professionals and the quality of work by Sean and the team was spectacular. Sean always picked up the phone and communication during the process was stellar. They showed up every day promptly at 8AM. They worked through the day with little or no breaks and at the end of the day they cleaned up everything. Sean partnered successfully with our designer. There were tweaks and changes along the way, and they didn’t blink an eye pivoting to get it done. At the end of the job, we had a small punch list that they plowed through without complaint, wanted us to be more than happy with the final product. To say we are ecstatic with the process and the end result is an understatement. ### All 47 reviews **★★★★★ — Shannon P, July 2025** > This is great team! Our projects with Conniff Construction ran smoothly. Communication was great. The work is flawless. **★★★★★ — Chris Motta, March 2025** > Conniff Construction built an addition on our home. We are over the moon with the finished product. Every part of the process from initial contract discussions to the final finishing touches was handled professionally and with integrity. This is a company you can trust with your projects to get it done right (and fast) the first time. Everything was well communicated, transparent and the skill and workmanship is top notch. My wife and I really appreciate how we were treated and there is not a single thing I would change. I'd give 6 stars if I could! Adding onto your home is a huge investment. When you take that big leap you want to know you can have confidence in the company you have entrusted with your home. Conniff is that company! I started with calls to 9 contractors. In the end Conniff came in with the best price. They got it done quickly (in some pretty challenging weather) and the quality was fantastic. If you're looking to improve your home you owe it to yourself to give them a call. They will not disappoint! **★★★★★ — HU-866478998, Feb. 2025** > Conniff construction completed a beautiful 400 sf addition, plus full siding, roofing, and decking, in 3 1/2 months for my family. Their quality workmanship, attention to detail, and open communication made the whole process go smoothly. The team exceeded our every expectation, treated our home as if it were their own, and we couldn't be happier with the finished product. If you want a reliable, trustworthy, efficient, on-budget team, Conniff Construction is it! **★★★★★ — HU-571833033, Feb. 2025** > Conniff construction was very quick, reliable, and professional. He kept us updated as the project progressed. The work came out amazing. We will be using them again for future projects. Highly recommend them to anyone and everyone! **★★★★★ — Joe F., Jan. 2025** > Conniff Construction recently completed our addition. Overall, Sean was great to deal with. He was very responsive, easy to contact, and willing to work with my wife and I. Additionally, I felt he was honest, upfront, and provided us with an accurate timeline for the project. His main workers, Jose and Ibrahim, were courteous, neat, and detail oriented. They did a great job with the tiling, flooring, molding, outdoor landing/stairs, etc. If we had an issue with something, Sean would have his crew remedy the problem quickly. I was also very happy with the work that the masons, spacklers, HVAC, siding crew, roofers, and plumbers did. Sean was willing to work with me as I did the electrical work and painting. Overall, I would give Sean and his crew an “A” on the project. I feel Conniff’s pricing was competitive and he gave us the attention we needed. My wife and I have settled into our renovated home and couldn’t be happier. I can tell that Sean cares about his company and the work that he is providing. I would highly recommend Conniff Construction for your next project! Below is a link to a post that Conniff made about our project. > > https://www.instagram.com/reel/DDADsPcxBd0/?igsh=MTdldzRycXRtY3g3cA== **★★★★★ — HU-302541964, June 2024** > We recently had the pleasure of working with Conniff Construction Company for an addition and home renovation project, and we couldn't be more pleased with the results! From start to finish, Sean and his team were exemplary in every aspect. Communication was seamless throughout the project, ensuring we were always informed and involved in decision-making. > > Sean's crew went above and beyond our expectations, demonstrating exceptional craftsmanship and attention to detail. They were not only skilled but also maintained a tidy workspace, which we greatly appreciated. > > Being a family-owned business, Conniff Construction Company exudes a personal touch that sets them apart. We've used their services in the past, and once again, they have proven themselves as a reliable and trustworthy partner for any construction needs. > > We wholeheartedly recommend Conniff Construction Company and will undoubtedly turn to them for any future projects. Thank you, Sean, and the entire team, for an outstanding job! **★★★★★ — Marianne Weathers, Nov. 2022** > Conniff Construction has been great from the onset of our dual projects. We hired this company based on reviews and seeing a nearby project in action. We had a 600sf master suite addition done as well as converting a single car attached garage to usable office/laundry space. We requested a few 'changes' along the way which Sean and his team addressed flawlessly. We have plans to use Conniff Construction for an additional home renovation project in the near future. Highly recommend them. **★★★★★ — Amanda Colie, March 2022** > So glad we had Conniff Construction take care of our master bathroom and laundry room renovations! Sean was so professional and always kept us updated every step of the way. Super knowledgeable, every one of our questions was answered quickly, and we never once doubted we had chosen the right contractor for the job! The before and after pictures still blow my mind! Thank you for helping us transform these rooms into something functional and beautiful! **★★★★★ — Design For the Times, March 2022** > I am an interior designer and recently had the pleasure of working with Sean at Conniff Construction Co. on a large kitchen and bath project in Mantoloking. This particular job was for a longtime client of mine, who relies on me for guidance and project management. > Unfortunately, I didn't know a local contractor and had to reach out to friends, who are in NARI, to recommend someone in this area. > Thank heaven it worked out! > Sean, the owner, is wonderful to work with and was extremely diligent - a true perfectionist in his skills. We worked well together and were able to solve any issues that came up throughout the project. > I would highly recommend Conniff Construction and look forward to working with him on other great projects. **★★★★★ — gary mulligan, March 2022** > I am a new small business owner of a new Dickeys BBQ Pit restaurant where I bought into a large franchise and had to find a GC to build out my store. Conniff Construction did not let me down they are persistent and constantly moving forward with quality material and craftmanship. I hit a lot of obstacles and set backs from financing to my plans. engineering and general issues with the building I leased. Conniff Construction went above and beyond every step of the way; reaching out to the franchise to get details they needed for a quality job and they where always there and available when I needed them most. I am very happy I picked the right team that is fair, reasonable and have a great work mindset for beautiful quality finished jobs. It can be confusing as to which General contractor you should use but if you picked Conniff Construction Family you already have a great start to your project **★★★★★ — HU-558250368, Feb. 2022** > Had a great experience with conniff construction. We needed two beams installed to make our home more open. They were on time and very efficient. Both beams were done in one day with no problems. After seeing the beams we decided we wanted one to be flush to make the kitchen have better flow. Sean got back to us right away and came out the next day to make the beam flush. We were definitely impressed we expected to wait since we know they are a busy company. Sean made sure we were happy. We look forward to using this company again for projects around our home. **★★★★★ — kathy reinhart, Feb. 2022** > We met with several builders about an addition we wanted to add to our home. Once we met Sean we were confident he was the right person. Sean has met all of our expectations and kept in contact with us through the entire process. If you are looking for a stress free construction project then Conniff Construction is the builder you should chose. **★★★★★ — Haley Ciocher, Nov. 2021** > Professional, trustworthy, compassionate, great communication, quality and thorough work, always on time and an overall great company! Would absolutely recommend to everyone regardless of the project size. **★★★★★ — HU-29931163, Sept. 2021** > Sean Conniff and his team are wonderful. Conniff Construction is VERY Professional, Clean, and knowledgeable. If you have Construction needs, Conniff Construction is the way to go. **★★★★★ — Diane Archer, Sept. 2021** > We hired Conniff Construction to rebuild our front porch, backyard pergola, reset stone pavers in our backyard/driveway and a few other retrofit-type repairs. We are very detail oriented clients and stipulated that all of the building material had to be Azek. Sean had to do some research on some of the Azek products we wanted to use, and even had to find a creative workaround to use Azek in a backyard railing retrofit. Sean Conniff followed our requests and requirements to the 'T'. > > Sean is EXTREMELY detail oriented, thorough and communicative. I cannot stress this enough. We have done many renovations & projects on multiple homes and working with Sean this time was like a breath of fresh air. We were not in town during the few weeks it took to complete our work so we requested daily text updates with pictures of progress. Sean did a timely and thorough job of keeping us in the loop and up-to-date. We spoke on the phone when needed and communicated by text and email when that would suffice. As a result he was always accessible within hours of us reaching out to him. > > Nothing slipped through the cracks on this project. Virtually unheard of with building and renovation work. Sean also made suggestions to us re: issues or things he discovered as they ripped up our old porch, and confidently suggested how he could correct for us. And he often did these small things at no extra cost! He has great integrity. He stands by his work, is fairly priced, and simply put, does not nickel and dime his clients. Again, a breath of fresh air. > > We would highly recommend Conniff Construction for any new construction and renovation/retrofitting needs. We intend to hire Sean and his crew for any future, small or large, project needs. **★★★★★ — escobedk, June 2021** > We met Sean Conniff at a home show and were impressed by this young man. When we were ready to have our house sided and a new triple double-hung window installed, we already knew we wanted to go with Conniff Construction. Thank goodness we did. Sean was patient with us, not high-pressure like some contractors, which was good, because we were back-and-forth with material choices and the like. Conniff's crew showed up on time each day, and the job was completed in three days. The house was beautifully transformed. What I most appreciated was that Conniff stuck with us, even afterwards, to apply some finishing touches, and Jimmy Hynes, who helped with this phase of the job, was great. Sean made us feel like we were his only customer, even though Conniff Construction had multiple jobs going at the same time. Not only would I, but I have already recommended Conniff to friends. **★★★★★ — G M, May 2021** > Sean Conniff of Conniff Construction is amazing!!! From the time we had our 1st consultation, I knew we were in good hands with our kitchen renovation. Our kitchen in Spring Lake looks awesome- what a transformation!!! Sean is professional, innovative and well skilled. He was always on time and met our expectations in completing the project when promised. No small feat during COVID! He coordinated all the subcontracting seamlessly. We were not onsite during the renovation and Sean kept in frequent communication with us including texting us multiple photos of the progress. We are extremely happy with our new kitchen and will definitely be hiring Conniff Construction for our next project! **★★★★★ — Carlos Acena, Nov. 2020** > Sean and one of his guys came home yesterday to work in my garage project. Showed up on time. Very polite and professional. Great and clean work. They finished in a good time. We will be using them for our future projects and highly recommend them to anyone. Thanks guys! **★★★★★ — Sonia Pinho, Nov. 2020** > Conniff Construction is the BEST! Sean and his team are professional, kind and hardworking. I will definitely use Conniff Construction again. As well as recommend to my family and friends. Thanks again Sean! ⭐️⭐️⭐️⭐️⭐️ **★★★★★ — Nanci & Coburger, Nov. 2020** > Conniff Construction LLC was a great choice for my kitchen renovation. Sean had lots of great ideas and kept me informed about the job. Beautiful craftsmanship! My new kitchen is open, clean and lots more cabinets and counter space. Its perfect. Should have done this a long time ago. I highly recommend this company. **★★★★★ — HU-200939594, June 2020** > Conniff is the best they are punctual, clean, courteous and the work they do is top notch the best around no doubt about it only use conniff construction **★★★★★ — HU-736285378, Feb. 2020** > Responsive, and professional every step. Returnrd my call in a very timely manner, gave an honest estimate, which came in right on the money. Did a great job, cleaned the work space better than any construction firm we've ever used. Sean ,and Jarod were excellent, and we will definitely use again for any construction needs. **★★★★★ — Julie Johnson, May 2019** > We hired Conniff Construction to address a few carpentry issues as well as install trim work (crown molding, shiplap and wainscoting) throughout our home. We also had them completely remodel our master bathroom. > > Sean Conniff is a stickler for details, and it shows in his work. One never has to worry about him getting it right. He’s way ahead of you in that department but always patient and thorough in answering any and all of one’s questions. > > He and his co-workers, John and Scott, work hard, are very pleasant and professional, and are unfazed by anything including my overly curious and energetic dog. They’re extremely neat – not only when cleaning up each night but throughout the entire process. They were prompt each morning and communicated any delay or hiccup in a timely fashion. > > We’re extremely pleased with their work. Our new master bath is stunning. I would not hesitate to recommend Conniff Construction and intend on using them for future projects. **★★★★★ — Erin Ehmann, Dec. 2018** > My husband are I are considering a large home renovation, We contacted Conniff Construction and Sean was unbelievably helpful in helping us to making one of our biggest decisions yet! We had a thorough phone conversation discussing all of our expectations and booked time to visit the property, take measurements and plan out our project. We have spoken to a few contractors and feel undoubtedly confident in Conniff to deliver us an outstanding finished product! Cannot recommend Sean and Conniff enough! **★★★★★ — Joe B., Nov. 2018** > Conniff Construction is by far one of the best contractors in ocean county!!! It's very rare to see the owner on site guiding his workings but that's exactly what Sean did. The worksite was always clean , he was always in contact and open to mid-project changes. The project complete date was even pulled in to accommodate my children starting school. Highly Recommended ! Excellent work ! **★★★★★ — Cory J. Anderson, June 2018** > I grew up with Sean and he always had integrity. So when I needed work done, and after seeing his work, he was obviously my first call. As expected, he did a great job for a very fair price. Also, as a real estate investor I know I can call him to get an honest opinion. And if it's something he can't do I know he will point me in the right direction. Highly recommend calling him first. **★★★★★ — kristendevuyst, March 2018** > Conniff Construction LLC did an outstanding job remodeling my bathroom.

A huge thank you to John for doing a great job making my bathroom upgrade appealing. Thank you Conniff Construction! **★★★★★ — Paul Foerg, Nov. 2017** > I was in need of a new roof. Sean came on the date as promised, his workmanship and professionalism were outstanding. When they were finished, all garbage and scrap was removed. The job was completed on time, on budget, and quality work. I have already contacted them for quotes on other projects. **★★★★★ — Bruce Garrabrant, Oct. 2017** > Replaced my deck boards that were in need of replacing. Removed old boards and removed same.

Sean Conniff responded promptly and professionally to our call. He was able to create exactly what my husband and I envisioned, turning our ceiling tunnels into architectural features that perfectly fit our style. Sean was a pleasure to work with. He was respectful, polite, knowledgeable and did a great job. **★★★★★ — Matt Webster, May 2016** > We had a glass mosaic backsplash done, and the fireplace done in the same tile.

LLC for nearly two years now and we cant be more pleased with the relationship between the two company's. Conniff Construction can be counted upon to take any corrective measures necessary to please their customers and meet the high standards of quality that a home owner/business demands. John and Sean are on site on a regular basis to inspect quality control. To that end,I would be proud to recommend them to anyone, business or homeowner. > > Joe Lopes **★★★★★ — tjlanuto, March 2016** > Our office has worked with Conniff Construction on several projects (residential and commercial) in the past two to three years, which our office wwas the Architects for the projects.

Overall, they did a great job and we would definitely recommend their work to our friends and family. **★★★★★ — Joe Oelshlegel, Aug. 2015** > I worked with Conniff Construction on the sale of a house that was renovated by them. The before and after pictures were amazing! Very professional with a great eye for detail. I would highly recommended them to anyone looking for renovation work! **★★★★★ — junenazar, Aug. 2015** > Sean was contacted to write an estimate for a realtors potential client deciding on what was the best answer to his situation of the status of his home. He was prompt and punctual and professional. He tried to get to the bottom of the clients requests...and financial position with the amount of funds and the work required, and the work he envisioned to revamp his home which had been affected by a fire. > Sean and the client were to meet afterwards to discuss the plans, prices, time frame, etc when the client got the answer from his ins. co and adjuster. This way then the final plans and prices could be determined as to the needs, wants, desires and funding would inspire the outcome. > Much to Sean's estimate abilities, and his technique of researching the scope of what the job would be and the homeowners stress and CONFUSION --- I have been told and passed the info to Sean that the homeowner said he had to go with the adjusters advise and their recommendation since homeowner was being housed in other temporary quarters and to continue the process he had to remain with them. (therefore I was told that was the reason why) > I would recommend Sean again. **★★★★★ — stephanie\_galler, Aug. 2015** > I have done multiple remodeling projects with Conniff Construction. As a family owned business, Sean and his father are professional, creative, and they respect project timelines. Their work is of the highest quality and their attention to detail guarantees that every job we collaborate on will have an amazing outcome. I recommend them to clients and friends and enjoy working with them. **★★★★★ — Ken Grosso, Aug. 2015** > Over the past several years I have used Conniff Construction on three projects, one commercial and two residential. Their professionalism is outstanding. It is rare today to find companies that actually do what they say they are going to do on time and on budget. They do a quality job from project management through job completion. Conniff Construction Co, LLC is a company that I recommend and will use again. **Comment from Conniff Construction Co.:** > Thank you Ken! It has always been a true pleasure working with you and learning much from you at the same time. We look forward to speaking with you soon! **★★★★★ — Debbie DeLuca, April 2015** > "Fred and I want to sincerely thank you for an excellent job! The family room addition and kitchen renovation will make our daily lives function much better and the overall transformation is stunning. We have done many home renovation projects throughout the years and the interviewing process is not a task that any homeowner looks forward to. We believe we made the best choice - Conniff Construction. John, your experience in the industry and craftsmanship is evident. Sean, your attention to the details and progress updates throughout the project was invaluable. Both of you truly made this process as easy as possible. Your suggestions throughout the design process were appreciated and your ability to maneuver around the inevitable construction obstacles was handled to our absolute satisfaction. Thank you for treating our home with respect and congratulations on becoming our "go to" home improvement contractors!" > Update July 2017: John and Sean just completed a poolhouse addition and it looks TERRIFIC! I wouldn't use any other contractors! > > ~Debbie Deluca **★★★★★ — lc1338, April 2015** > I contracted with Conniff Construction in February 2015, and I couldn't be more pleased with the experience. > > As a result of a previous fraudulent contractor, I was left with a barely functioning bathroom in my home. Due to a mold issue, homeowners insurance granted us coverage for a bathroom repair. We didn't do our due diligence in selecting this original contractor (reading reviews, browsing the internet for credentials/past work, etc), and we suffered because of it. The previous contractor came in, ripped out all the walls and flooring, destroyed the plumbing, and ran off with the money - leaving us still with the mold problem and without a functioning bathroom. > > Conniff Construction came to the rescue and repaired our bathroom beautifully, and in a timely manner. Both Sean and John were extremely professional to work with, and had only their clients best interests in mind. They put our bathroom back together, including a custom tile floor job, reinstallment of sheetrock, rerouting of problematic plumbing, installation of new tub and removal of old tub, and most of all - rid us of the mold issue. Conniff Construction worked with us patiently while we went back and forth on design decisions. They installed all of the bathroom furniture, including vanity, mirror, and lighting. > > I felt extremely safe with having them work in my home alone, without supervision. They are safe and professional, and pose no risk from a safety or financial perspective. They are diligent and organized in their documentation, including their contract and estimates, and belong to multiple verified home owner's and builders associations in the state (as well as nationally). We felt very safe in their hands and we are confident we made the right decision in choosing them for our renovation.
