"We had a phenomenal experience with National Home Design & Build and can’t recommend them enough. Patrick was with us from concept to permitting to demo to build and we are absolutely thrilled with our new space. We had a loft space that made several hundred square feet of unusable space in our house. Patrick worked with us to understand the design options, work us through the concept and process, did all of the permitting and managed the process from start to finish. We now have a full third bedroom in our house, a brand new walk-in closet, a new ceiling and lighting in our kitchen and we also had them replace all of the carpeting in our second bedroom, hall, two staircases and a closet. We can’t recommend them enough and Patrick will be our first call the next time we need to renovate."

"We're in process of getting bids on a deck/exterior office space remodel. They were very responsive to our initial request, and we talked to one of the owners of the company via phone and in person within 7 days of our outreach. The project is probably too small for their level of services, but we will definitely consider using them for a future, more complex interior home renovation. They were very nice and giving of their time and expertise, and their build process seems very professional and polished. We had an excellent experience with them."

"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."

"Jose and his crew are outstanding. Their attention to detail, cleanliness, and respect of our home was incredible. Jose is so easy to work with and he is accessible almost 24/7. I would highly recommend Munoz construction and my family will never use another contractor besides Jose. Bathroom #1 - this bathroom had major issues. The floor was damaged and the shower was leaking. Jose replaced the entire subfloor, shower/tub, title, vanity, and all electrical. This was a major job. Everything was strengthened and given strong structural support. It is now extremely safe and beautiful. Bathroom 2 - the master shower also had a leak and poor tile work from a previous remodel. Jose replaced all the tile and rebuilt the shower pan. He was able to save an expensive shower door from the previous remodel. We also decided to replace the title floor during the remodel and it was not an issue and Jose never questioned our request. LVP Floors - Jose replaced the kitchen, dining room, hallways, and stairs with LVP. Selecting the product was simple and Jose was helpful throughout the entire process. The product was of high quality and is extremely durable. The stairs were replaced with wood and painted to match the LVP. This was done for durability and quality. The stairs match the LVP perfectly. All the walls were also painted. There was some drywall repair throughout the process too. Jose made sure to strengthen all the walls and it looks fantastic. Seriously, we couldn’t be happier with this job. I wish we would have found him years ago so we wouldn’t have had to redo a previously completed renovation done by another company. We highly recommend Jose and Munoz Construction for any and all jobs."

"Excellent diagnosis of the work needed. Complete review of external meter and cable rigging needs, upgrade to new panel inside the house and corresponding grounding under the house (crawl space). Very reasonable pricing as well. I’ve hired D&G Remodeling for the work. The Lord is good! Thank you Angi! "

"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!"

"Several people recommended Jae and Connor Construction to us when we were beginning our home renovation project. We hired Jae and his team to convert our screen porch into a year-round living room, update lighting in two other rooms, and a few other updates in our kitchen and adjoining rooms. Jae is responsive, communicative, transparent, and always a pleasure to work with. He promptly helped troubleshoot when issues arose, including with the county permit application process and the unexpected that comes with renovating when using an existing structure. Jae was a calming presence during the inevitable ups and downs of a renovation, and we were always confident that he would help us reach the result we wanted."

FAQs for addition to existing structure building service projects in Chantilly, 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.
