The Dewson team repeatedly showed their home-building expertise by making many thoughtful suggestions throughout the planning and construction process that significantly improved the end result. > Dewson’s craftsmanship was excellent and the attention to detail was impressive. Our house has a great deal of intricate millwork and tilework and the end product is beautiful! > Dewson’s customer service was also great. For example our project manager came to the house during a nor’ easter to make certain the basement was dry and that the rest of the house was ok (even though he wasn’t scheduled to be working on the house that day). My father-in-law, who knows construction, commented, “Now that’s a good construction manager!" > We couldn’t be more thrilled with our home! Many thanks to the Dewson Company, John McMahon, and Kevin O’Grady! **★★★★★ — Linda McCormick, Nov. 2016** > We'll be ready to move into our beautiful new home in about 2 months (right on time) and we can't wait. This is the first house we've ever built and contrary to the headaches and problems we anticipated, the process has gone very well thanks to Dewson Construction, who have been so helpful in every phase, including maximizing our budget. We are confident that our satisfaction is a priority with them and our wonderful site manager is priceless. If we should ever decide to build again, we wouldn't even consider another company. We can't recommend Dewson enough, from Mr. Dewson himself down to every subcontractor. **Comment from Dewson Construction Company:** > Hi Linda, > We are so grateful for your kind response. We are thrilled that you are so happy with your home and the process. We do what we do because we love building beautiful homes and love exceeding client expectations. We are sure you will have many happy memories to come in your incredibly gorgeous home! **★★★★★ — Patricia Loew, July 2016** > Working the Dewson Company has been a great experience. They were recommended to me by the architect on the project. > > The quality of their workmanship is outstanding. The people at Dewson were so nice to work with - nothing was too much trouble. > > I would recommend Dewson to anyone! **Comment from Dewson Construction Company:** > Thank you Mrs. Loew for your nice words. We loved this project! **★★★★★ — The Interior Collection, April 2016** > As an interior design firm located in Southlake, Texas, we had an outstanding experience working 'side-by-side' with the Dewson Construction team on a new build on the shores of Delaware! From the initial on-site meeting through the final finishing touches, Dewson Construction executed everything exactly as we specified - seamlessly - and most of our communication during the building process was conducted 'long distance'! Our collaboration with Dewson created a beautiful space for the homeowners and the results were spectacular. Their scope of work, architecturally as well as their attention to detail, resulted in a creative, high quality custom home for our clients. The entire Dewson team is an exceptional group of professionals that are friendly and helpful on every level. We look forward to working with them again in the future! **★★★★★ — petejones84, Dec. 2015** > The Dewson team has been an absolute pleasure to work with and the results of their work could not be of higher quality. Our home renovation was completed by true craftsman who attended every detail to ensure historical accuracy. Tim and his team took a set of guiding standards from us and created results far beyond our original expectations. Our project is one which will be admired for years to come. **Comment from Dewson Construction Company:** > thank you so very much for your kind words. We at Dewson pride ourselves on making our clients happy and by focusing on every detail we accomplish that! **★★★★★ — Natalie Bush, Dec. 2015** > Dewson Construction did an amazing job on our home in Rehoboth Beach. The whole team was a pleasure to work with every step of the way--from planning with Jamie and John to our project manager Paul. The team worked with our schedule--we live out of state--and we stayed on schedule for the project. Paul was always willing to be available when we were in town. > We have built several homes and this is the first one where the construction site was always organized and clean! That attitude was reflected in the entire process where attention to detail was evident in every aspect of Dewson's work. Thank you for helping make our dream a reality! **★★★★★ — Jay Townsend, Nov. 2015** > We have built several houses, with various builders in Texas, Carolinas, and Delaware. This experience was clearly the best. Quality, attention to detail, and overall "can do attitude" was superior. There were no loose ends, or communication gaps during the design or construction phase. Quality is best we've seen. **★★★★★ — zudie, Sept. 2015** > Having built several previous homes we were prepared for the usual difficulties one encounters during the construction process. Working with Dewson was very different and actually quite pleasant. From the regularly scheduled progress meetings to the helpful advice offered by them, together we have built a wonderful house. They interfaced effectively and frequently with both the architect and interior designer to meet our expectations. **★★★★★ — User, Aug. 2015** > Our firm has collaborated with Dewson Construction on over 20 custom home and renovations projects over the years. From the smallest home improvement project to the largest luxury custom home, Dewson always delivers exemplary quality with construction and finish. They pride themselves in developing lasting relationships with their clients while guiding them through the construction process. **★★★★★ — annegates, Aug. 2015** > Dewson construction exceeded our expectations during the building process of our new home. The customer service and quality of work from beginning to end was unlike anything we have every experienced. They made an otherwise very difficult custom construction job very manageable and pleasant, while instilling utmost confidence in the the quality of work being done. I would recommend them to anyone interested in building their custom dream home. **★★★★★ — rhoadss, July 2015** > We hired Dewson Construction to build our house. They were excellent throughout every phase of the project, from conception through completion. They thoroughly reviewed all subcontractors and made excellent recommendations. Even now, several years after completing our project, they are still available and happy to help if any minor issue comes up. We would definitely choose them again. **★★★★★ — lizziebarnhart, Jan. 2015** > Top-notch builders who were able to see the potential in our renovation. We interviewed several builders and these guys are the best of the best. We were astounded by their beautiful craftsmanship and attention to detail. Every step of the way they were in constant communication about the project. Working with Jamie and Ashley was a very smooth and enjoyable experience. We would not hesitate to hire them again and again. ## Selected projects - [New Construction - Transitional](https://www.houzz.com/hznb/projects/new-construction-transitional-pj-vj~6482766) - Location: Not specified - Photos: 30 - [New Construction - Contemporary](https://www.houzz.com/hznb/projects/new-construction-contemporary-pj-vj~1211777) - Location: Lewes, DE - Photos: 16 - Description: Take a look at this gorgeous custom built home on the water.

Thanks Michelle A: Hi Michelle, The skirting is all wood. We have amazing craftsmen here at Dewson. They painstakingly "bend" the wood using various methods to get the desired effect. Hope this answer helps. **Q: Из какого материала сделан белый портал** *(in Photo Questions)* Добрый день, Уважаемые эксперты! Мне нравится камин, подскажите из какого материала сделан белый портал и еще, мне кажется или топка открытая, т.е. без дверки? A: The fireplace has a marble surround finished with a wood mantle piece and framing. The fireplace is an open concept without a door. Камин имеет мраморное окружение, отделанное куском деревянной мантии и обрамлением. Камин - открытая концепция без двери. **Q: Center riser** *(in Photo Questions)* Love the center riser on the island to hide sink. Can this be put in after island already in place? If yes, how, any tips? thanks! A: Hi, This was installed prior to countertop being templated. It would be best to consult with a countertop specialist to see if it's something that can be added after the fact. **Q: What are the backsplash tiles? Are the cabinets pure white or cream** *(in Photo Questions)* A: the tiles are Lagos Azul Limetone. the cabinets are not pure white; they are a softer white, but not "cream". Hope this helps. **Q: We like the flooring, what is it and where did it come from?** *(in Photo Questions)* A: Hi. Thank you. It's limestone with black tile inset. --- *Source: Houzz professional profile. Reflects the profile as of 2026-09-02.*
