"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."

"ICM Remodeling was the winning bidder when I recently upgraded my 2 bedroom condo.  The work included removing a portion of a wall to create a kitchen breakfast bar area, gutting and completely replacing the kitchen and bath, repainting the entire condo and installing new carpet throughout.  ICM's bid was extremely competitive and included mostly labor.  As for material, Israel worked very closely with me in selecting and purchasing new tile for kitchen and bath, new cabinets and vanity, lighting, toilet and tub.



The installation went quite smoothly, with cabinets, new kitchen appliances and other materials arriving on schedule.  In many cases, ICM picked up the material from the supplier.  Several times, ICM also helped with the delivery of items from independent retailers.  ICM also worked with the granite supplier in the installation of the new kitchen countertops.



ICM made sure to cover the furniture, tables, television and electronic equipment during the project, in order to protect them from dust.  They were diligent about cleaning up and making the condo livable after work each day.  At every step, Israel was very good at explaining what to expect, the progress of the job, and how everything would look.  We was always available to discuss my concerns, and was responsive to all my questions and requests.  He showed up when he said he would, and his staff was competent and helpful.



When the bulk of the project was complete, Israel and his team went through and addressed each one of the touch up items to my satisfaction.  In fact, ICM went beyond my expectations in making sure I was pleased with all aspects of their work.



I highly recommend ICM Remodeling.

"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!"

"Awesome experience with Total Renovations, LLC. Knowledgeable, responsive, considerate, patient, went above and beyond, informative, a true professional and fair. These are all qualities that were consistently adhered to when working with Russell and his team at Total Renovations, LLC. Having never gone through a home renovation process, we were a little bit skeptical as to which company we wanted to hire to undertake the task of transforming a two-story living room area in our home into a space which converted the upper portion into an additional bedroom. After an extensive search, we found Total Renovations , LLC and its owner, Russell. From day one, which was actually a few months before we hired him and his team, Russell was extremely pleasant to work with. I called and informed him of the task we were wanting to have completed, as well as the fact that we were new to this experience. He was very patient in explaining the entire process from start to finish. Once we had a signed contract between ourselves and Total Renovations, LLC, Russell took it from there. Whether it was obtaining architectural drawing designs, permits from the county, or the construction and clean up of the project, Russell and his team took care of every step along the way. Unlike some other companies that may be dismissive of your project if they feel that it won’t make them enough money, or are dismissive of your task altogether, Russell and his team were a complete joy and relief to work with. They are very punctual, as they show up on time, every time. And I mean EVERY TIME. Additionally, his crew made sure to do an excellent job cleaning up after each day of work. This was truly appreciated as we have a young child and a dog living in the house as it was being remodeled. In this market and with inflation being what it is, we all know that some companies may try to stiff their customers by engaging in price gouging here and there. That was not at all the case with Total Renovations, LLC. The price that they quoted us and signed for was what was adhered to. If anything came up in the project where a particular aspect needed to be changed or corrected based off of the initial assessment, Russell always made sure to reach out to us immediately to explain the reason as to why, as well as obtain permission to proceed. That particular point was extremely reassuring, whereas some other companies may just add extra work to your project without notifying you and then hit you with an inflated bill at the end. At no point in time did Russell ever try to oversell me on any aspect of the project, nor did he brush aside any issue that other companies may feel to be trivial. If we had a question or a concern, Russell had an answer or a solution. Russell and his team were able to take a vision that we had in our heads for our open space, and literally turn it into a reality. Additionally, we were able to add in some recessed lighting and ceiling fans along the way. The attention to detail that his crew invested into our project was above and beyond even our own expectations. It truly feels like we are living in a new house. If you have a task or project that you’re thinking about having done with your home, we HIGHLY recommend that you chose to hire Russell and his team with Total Renovations, LLC. We guarantee that you will not be disappointed. We also guarantee that you will love the end result."

"Tony and his crews have completed two major projects (family room addition and kitchen remodel). We plan to have them complete a master bathroom remodel. They are professional, clean, kind, and honest. I trust them to be alone in my home. They answer any and all questions that I have about the work and future maintenance for the work that was done. Highly recommend. Thank you Manex Remodeling"

"Five years ago Rick and his team had completed a full rehab of our deck and we love it. Recently, a material defect occurred and Rick stood by his work when the manufacturer would not. At his expense, he got new material and provided the same great carpenters, (Skip, Gary, and Heracio) as last time and made things right. I highly recommend their work and am happy to share their name with everyone who enjoys our deck. Check out the photos.Thank you again."

"I found Navid’s Construction to be first rate in not only only their work and craftsmanship but also their customer service commitment to take care of all the little things that make the difference. I highly recommend them to anybody in need of their services. while the work was interior work, they spent a lot of time prepping outside on one of the coldest days of the years without complaint and stayed until the job was done. Very satisfied customer!"

FAQs for addition to existing structure building service projects in Fairfax Station, VA

You can typically raise your roof by four to eight feet, depending on your home's structure and roof design. The exact amount depends on factors like roof slope and framing support. Raising the roof creates additional interior space, enhances natural light, and increases your home's value. Consult a professional to determine the feasible height increase for your home.

Yes, you need a building permit to raise your roof. Obtaining a building permit ensures your project complies with local building codes and safety regulations. A professional contractor can assist with the permit and inspection process and ensure all legal and safety requirements are met. Your contractor will be familiar with building codes in your area, which can differ between cities or states.

While it's possible to raise a flat roof, it requires extensive structural modifications. Flat roofs lack the attic space and support structures of pitched roofs, so raising them involves significant engineering to ensure safety and durability. This process can be complex and costly, so professional assessment is essential before undertaking a project of this magnitude.
