Get matched with top addition to existing structure builders in Great Falls, VA

"Two By Four Construction did an excellent job designing and building the front porch that my wife and I always wanted. The crew showed up as promised and were prepared. They kept the worksite clean and safe. Gary kept us up-to-date on the work and deliveries. that he had scheduled. The quality of the work was well beyond our expectations. I would highly recommend Two By Four Construction LLC."

"We are extremely happy with the work done by Thomas Custom Builders (TCB). Overall they did an amazing and outstanding job! They had a contractor on site, on time every day. Brian S. was professional, helpful, patient, hard working and skilled both in managing subcontractors and doing work himself. I trusted him with our home and would work with Brian/TCB again easily. I have already recommended their company to others. TCB renovated a few parts of our house, added electricity to a shed and added an entire master bedroom suite on an additional floor (adding approximately 550 sqft to our house). They finished earlier than expected. Our neighbors couldn't believe how fast the addition was completed and how well done. Any additional costs from the original budget estimate were due to our choice to add more work. I waited to write a review. I wanted to live in the addition for a little while to see how everything holds up. We have had only minor things arise and have been very pleased with the responsiveness of Brian and TCB to come back out and check on things. They came back to add a bracket to a new countertop that moved slightly, they shaved a door that was sticking as the weather changed, they fixed the damage done when carpets were installed by another company, they arranged for a rep from the hot water heater company to come out and fix a noise issue, all done at no additional cost to us. I have worked with contractors before but nothing on this level. It wasn't perfect, there were concerns that came up. I had to learn that this was major construction and with major construction comes mess. Brian and his team addressed our concerns and remedied any issue fairly. With so many negative stories I've heard from people who worked with other companies, I am so very thankful that we had such a good experience and ended up with such an amazing master suite and changes to our home. We love it and we receive many compliments. We chose to work with TCB because they came highly recommended by a neighbor who had similar work done and were very satisfied with their outcome."

"They did excellent work.  They were very honest and very efficient.  They were very punctual.  They provided me with very good feedback.  They provided me with ideas that will solve problems.  So it was not just having me solve the problem but they were willing to solve the problem with me and to do so in affordable fashion.   

They were very professional the entire time."

"Capestone and his expert crew were amazing to work with. Timely, organized, respectful and performed additional work outside of original scope. Transparent about all additional costs. Finished product was beyond expectations! Added heated floors and removed, restored, installed historic windows and doors on 1930s home to maintain home and neighborhood aesthetics. Next project planned for another bathroom and three doors!"

"We loved working with Cosmo builders on our new custom home construction The cosmo team and their sub were very professional, patient & helpful on every step of the process starting from first estimating, understanding of our budget needs, customization of the finishing materials, Fixtures choice based on our budget. also they were a great advisor for me during the process on the selection of materials, design, colors and electrical fixtures. moreover, they created a modern and customized beautiful bathrooms and kitchen that was just what we wanted. despite that, the crews were very polite, technical and passion for the quality work. with help of our contractor cosmo builders, we have unique house floor plan and a clean interior house design while the building process took little bit more time than normal! but it's okay because we end with satisfaction, We have been extremely happy with the quality and craftsmanship. I definitely recommend cosmo to anyone who are looking for right contractor to redesign/build or manage residential project,and i hope to work gain with them soon on our third investment project in the future again."

"Best contractor I ever worked with is Marvel Homes, (301) 785-2171, a small firm owned and run by Devin Nasvaderani, truly one of the nicest, most knowledgeable, most organized and honest people I have ever worked with. I have done three projects with him, and been thrilled beyond expectation each time. Devin's is the firm I chose to rebuild the damaged portions of my house after a big fire there. Because we had been through so many problems with other contractors leading up to the rebuilding - despite checking them out and watching them closely - we were REALLY careful before selecting the contractor who would do the rebuilding. We read EVERY single detailed review on Angie's List, we interviewed the top "contenders," and chose Marvel Homes. Even with all of this high expectation, I was blown away by the experience of working with someone who is honest down to his bones, cares about the quality of his work down to the smallest details, is a phenomenally good carpenter with a small crew of stellar, hard-working people he trained himself, was spot-on with every time estimate and cost estimate - and for all of this is relaxed and warm at the same time. They say at the end of a long project with even a good contractor you are "sick of each other" by the end - on the contrary, I was actually sad when the work was done, that's how positive the experience was. In fact, when we needed to replace old windows at my family's house, and I wanted to winterize my screened porch, I chose Marvel Homes for each of those projects and the experience was every bit as positive. I will give details that may help give you a fuller picture of our positive experiences with this business. 1). Many contractors we spoke to came with glossy brochures and polished salesmen. Devin came himself, no glitz or fake conversation, looked at the job with what was clearly a trained eye, and answered all of my questions honestly and to whatever detail I needed. After all we had been through, I had gotten so sick of the "schmoozy" soft-sell/hard sell routine of the bigger companies who talked a lot without saying anything, this was like a breath of fresh air on a stuffy day. 2). His low-key demeanor may fool you. Devin is the most skillful and experienced carpenter/craftsmen and most organized contractor I ever met. He looks with a trained eye at every aspect of the job, and is clear and up front down to the smallest details. He wakes up at 5 each morning and before he leaves for his first job or meeting, he has a print-out of each and every thing he needs to do or discuss on each job, site, or client he will meet with that day. Unlike many good contractors who are not so good with paperwork, Devin's paperwork was so helpful all throughout the project, for planning, knowing when we needed to make choices of materials, knowing when to expect which aspect of the job, knowing breakdown of costs - everything. 3). He does it right. Even if it costs him, he absorbs the cost to get it right. In contrast to the companies that would spend hours talking to me without providing any detail or accurate estimates at all, Devin spent 40 hours of work on his own time without getting paid for it, in order to get accurate estimates and details on each aspect, so I knew exactly what to expect time-wise, and cost-wise, so the insurance estimate would be spot-on, etc. 4). When the refrigerator came, I had chosen a bigger one than we had planned for. The island was already in, but Devin was concerned that with the few extra inches of the refrigerator, the smaller aisle space might be annoying when we would be using it, moving about the kitchen, etc. He arranged to meet me at the house to see what I thought, and then suggested we move the island a few inches back. Despite the fact that I was the one who had chosen that particular refrigerator, he did not charge me for the cost of moving the island, even though I suggested that that was only fair. He said something like, "the job isn't done into you are happy, and we get it right." Who does that? 5). His small crew is terrific. He has trained all of them, and treats them well, so they form a really cohesive team. They arrived on the dot when they said they would, and they left the work area and house cleaner than when they arrived. The respect they showed for me and my things was remarkable, which blew me away after having worked with companies that treated my house like their own work space, without regard for the people or things in it. 6). We had to work with insurance on the big job. Devin's estimate was so "on point" that there was no dispute over any of it, the insurance issued the check without delay. His time estimates of when a part of the job would be done were true and exact, making it possible for us to plan around when certain parts of the job would be done. And his cost estimate was exact also. He is licensed and bonded. He does things by the book, and in fact, the only "negative" comment we ever found for him on Angie's List is "he refuses to use cheap materials." Thank goodness he doesn't. There were so many things I noticed after I moved back home that I never would have noticed while the job was underway, so many corners a less honest or less skilled contractor could have cut that would have slipped by me until long after they were paid and gone. I can't tell you how many times I felt so grateful that we had found Devin. The fire was a nightmare in so many ways, but I have often said that finding Devin and Marvel Homes more than made up for it. His reputation for excellent, by the book, safe work was clearly known to county inspectors, and every inspection went smoothly, without surprises or problems. After you have had a fire, you especially appreciate a contractor that does it safely, and right. He charges a fair price for high quality work. Before Devin I used to try to get things done at cheaper prices. The work was cheap and I would have to supervise every inch and every minute of it to be sure, and even then, I got burned. Devin told me once that a large portion of his jobs are coming in and doing it right after someone cheaper botched it up. Having now worked with a company where I didn't need to supervise ANYTHING to get a proper, careful, skilled result and promised result, I will never go back to the other way."

"Completed an upgrade to our 40-year-old kitchen w VKB Kitchen & Bath. Calvin worked closely w us on the design to get small cabinet and counter space in our townhouse. Al was our PM for the demolition and build-out phases. Al had the challenge as PM to coordinate demolition, new flooring on 1st level, electrical changes, cabinet installs and new fixtures that we purchased. They installed new disposal and ceiling fixture at no charge. No change orders on project. No gaps on work sequence. Finished in half of the contracted days. Great company, designer and PM."

"Project went awesomely. Alberto Velasquez and Javier Jiron were amazing. Completely took care of all of our wood issues having to completely remove a door and a window. Exterior power washing and painting went very well too. Done in the allotted amount of time even though they encountered additional unexpected damage. We need to have more work done and I will specifically be asking to have these two back to do it. Very professional. Very understanding of our protective dogs. Very happy! Thank you!"

"It was great, we love our extra addition room Thanks to NV Design and Build"

"Great company to work with from the initial bidding process to completing the work. Sean, Min, and the rest of the team did a fantastic job building our addition. They took care of all of the permits needed and helped with additional work that was needed. Highly recommend US Home Design Build if you're looking to build an addition to your home."
