Featured Reviews for Home Addition & Extension Contractors in Washington D.C.

Marks-Woods Construction Services, LLC
Home Addition & Extension Contractors in Washington D.C.
Average rating: 5 out of 5 starsNovember 27, 2013
“Work was completed in my kitchen - removal of one wall and existing floor (3 different types); reconstuction of pantry; installation of new 3 drawer cabinet, new floor, countertop, back splash, and new lighting. MW Construction management and staff were very professional and courteous. The staff came as scheduled and management kept me appraised of progress throughout the project. Management personally helped with my selection of flooring, countertop, and back splash; and I received contractor pricing even though I personally paid for the items separately (no overhead added for MW Contruction). Items in and around contruction zone were protected throughout the project and construction area was cleaned up at the end of each work day. The end result is beautiful and of high quality. I would recommend MW Construction Services, LLC., to anyone and everyone.”

“We hired RLA to design our custom house which was recently completed in March 2015. We couldn't be happier with the results and would recommend them to any prospective home builder. From the beginning, we knew we did not want the standard cookie cutter two story colonial that is everywhere in our area, we wanted a custom house with a modern esthetic, not an existing builder plan with a few modifications. Builders will typically tell you that you do not need an architect, and that may be true from a construction perspective, but by forgoing an architect, you lose the opportunity to build a really special house, customized exactly to your needs. It does not add that much extra to the cost. From the beginning, RLA listened to our ideas, paid attention to our budget and designed our home to our exact specifications. While there are many illustrations of how this benefited us, here are three examples: Orientation - we wanted a house that would take the best advantage of natural light and available views. RLA worked hard to orient our house properly on the site and we now have great light, great views and privacy where we want it. The room layout also makes maximum usage of available light and each room has a great view. A builder will just plop your house on the site facing the street, regardless of the orientation of sunlight or privacy. Details - RLA incorporated details in our house that give it that custom, personalized look. Our deep soffitt details, rock stair wall and porch are really unique. Proportions - This is a hard one to describe, but RLA did a great job with sizing details, the proportions including room sizes, trim details, etc. Everything in the house flows beautifully and feels balanced and gracious. Architects understand how big rooms should be! Not to big or too small. My advice to prospective home builders is to forgo more square footage for better advice, materials and design. An architect will ensure you have a really unique home that fits your lifestyle”

“I truly want to point out the professionalism of United Cabinet Store. We had a very pleasant experience with this company. They had renovated our kitchen for a fair price compared to other remodeling companies out in the MD area. Very knowledgeable and helpful customer service. Alex was very professional and very to the point where we needed some clarifications regarding to questions and he took his time to answer every each one of them. We were astonished with their service and didn't really expected this much help from them. 5 star for their service. Thanks again for helping me getting a brand new kitchen.”
CDR Contractors
Home Addition & Extension Contractors in Washington D.C.
Average rating: 5 out of 5 starsMay 3, 2023
“My bedroom ceiling and floors were damaged from a storm over a year ago. My coworker referred me to CDR Contractors and I’m so thankful I called for their services. They are professional, dependable and great customer service. They also offered me a very reasonable quote. They did a great job on replacing my entire ceiling and floors. In both cases, Mr. Drew, the CDR Contractor owner walked me through the process and took care of communicating with my insurance company. I truly appreciate that he updated me every step of the way. Prior to the remodel, I suffered from severe allergies because of the old ceiling insulation. Not only they replaced the entire ceiling and floors of my bedroom, but they also painted the walls, installed a beautiful ceiling light/fan and flat screen tv. The work was completed in a timely and professional manner. I’m very happy with my bedroom make-over, a place to relax from a stressful day at work. I highly recommend CDR Contractors for your home remodeling needs! I will definitely contact them again in the future.”

“I had the pleasure of hiring Finecraft for a project recently that called for the addition of an outdoor living area to my home. The level of detail and commitment to quality was unsurpassed. These are Craftsmen, not contractors. It shows in every project they create. JF Homeowner”
Michael Nash Design, Build & Homes
Home Addition & Extension Contractors in Washington D.C.
Average rating: 5 out of 5 starsOctober 17, 2013
“My wife and I selected Michael Nash from among five separate bids for a considerable renovation and expansion of our home. Michael Nash was the second lowest bidder, but our confidence in Sonny Nazemin’s eye for design and considerable number of award-winning designs was crucial in our initial selection. We have a grand house in Reston built in the late 1960s. It has solid bones but really needed a whole house renovation. We also needed more space to house our extended family. Our project consisted of a new two-car garage, siding, roofing and a totally new floor consisting of a master suite and bathroom. From the start of the project I was impressed with the one price upfront to complete the project. Sonny navigated our plans through the difficult process of approval by our local Design Review Board. His personal attention and negotiation with the board led to the rapid approval of our project. Follow on work for our front porch and driveway was reasonably priced. When we requested a re-design of the ceilings for the master suite, Sonny spared no expense hiring several architects to arrive at the design we desired. His vision throughout the project ensured its success. ******************* EXTRA FOLLOW-ON WORK COMPLETED jANUARY 25, 2014 *********************** We gave Michael Nash extra follow-on work with our kitchen because we were so pleased with how our Master Suite and other work turned out. We told Sonny that we had a limited budget but wanted to get as much of the kitchen done as possible. He suggested that we keep our old cabinets and redo everything else. Sonny has a great eye for design and suggested that we take out some cabinets to open up the room. He helped us with color choices that made the kitchen modern and bright. They replaced the oven, the hood, the induction cooktop, the counter, the floor, the sink, repaired and replaced doors, painted the room and put in a new lighting system with ten canned lights. Michael Nash kept to a timetable except for the hood at the end, which was really unavoidable. We are thrilled with our new kitchen and recommend Michael Nash to our neighbors and friends.”
Four Brothers Design + Build
Home Addition & Extension Contractors in Washington D.C.
Average rating: 5 out of 5 starsAugust 8, 2012
“This company is amazing! I hired Four Brothers to remodel my kitchen and two bathrooms, and could not be happier with the final outcome as well as the process. I was apprehensive going into the project because of horror stories I had heard about remodeling companies. Nothing to worry about with these guys! From the initial consultation on, their people were professional, knowledgeable and best of all, listened to my ideas. Their designers had creative and functional solutions and their carpenter and his crew were fantastic. They respected my schedule, kept my home clean and delivered on time and on budget!”
Cabido Design & Build
Home Addition & Extension Contractors in Washington D.C.
Average rating: 5 out of 5 starsDecember 19, 2017
“JCabido Remodeling makes sure assist their customers in whatever they are needing to the extent they need. For example, if their client wants help picking out stone in our warehouse, we always see them come in with them to make sure they are getting taken care of. If the client wants to pick out a stone themselves, that's what happens! They make sure their clients are choosing the products they are wanting in their project all the while being honest and upfront about costs. They have a knowledgeable staff and make sure quality is never undermined. We love working with JCabido Remodeling and look forward to continuing our business with them!”
Alair Homes Arlington
Home Addition & Extension Contractors in Washington D.C.
Average rating: 5 out of 5 starsJuly 14, 2013
“In the past we used a design/build company and did not feel that we had control over the process or the budget. When we reviewed the bill we found the mark-up was excessive, especially when sub-contractors were used for most of the work. This time around we chose to use Chad with Arlington Construction Mangement because of the ability to control expenses, choose the products used in building our addition and select our own sub-contractors. The ability to get several estimates and meet the subs for each trade beforehand made a huge difference in our experience. We completed our project 2 months earlier than predicted and were able to stay within budget. We ended up saving 28% from our lowest bid and we were able to use upgraded products along the way. Chad gave us great advice, support and knowledge to help us through our project. I know we would not have received the same personal service from any other builder. We would use Chad again and would highly recommend him to anyone looking into building.”
Moser Architects PLLC
Home Addition & Extension Contractors in Washington D.C.
Average rating: 5 out of 5 starsMarch 3, 2016
“I recommended Moser Architects, PLLC to everyone looking to build or renovate in the DMV area. Sarah took our quaint Cape Cod home in North Arlington and made it into a beautiful home for a growing family. We told Sarah how we wanted to keep the charm and curb appeal that fit the neighborhood, and she surpassed our expectations. Our home could not be more functional thanks to Sarah's expertise, and we are always receiving compliments. Our open floor plan with large amounts of natural light could not be more perfect. If we ever take the plunge to purchase another home in NOVA in need of renovations, Sarah will receive the first phone call.”
