HOME ADDITION FAQs

Common questions.

Still have a question? Call 703-587-7762 or contact us.

Additions vary widely with size, type, and complexity, a sunroom and a second-story addition are very different projects. Because they involve foundation, structure, and finish, we build a detailed scope and budget together up front.

Additions generally take a few months, longer than an interior remodel, because of design, permitting, foundation, and structural work. We give you a clear schedule before we start.

Yes, additions require permits and often HOA or county approvals. We handle the permitting and approval process for you, and we know the local requirements in Fairfax County and the surrounding areas.

That's the goal. We match rooflines, siding, trim, and finishes so the addition looks like it was always part of the house, not bolted on.

Yes. Every home addition is backed by our 10-year transferable labor warranty.

 Trustindex verifies that the original source of the review is Google. We recently had our roof replaced by Main Street Home Improvement Company and couldn’t be happier with the experience. This was actually our second time working with them after a deck installation, and once again they delivered excellent results. Their proposal was also the most competitive among several quotes we received, but what really set them apart was the level of service. Mike was outstanding — he went above and beyond to make sure every detail was handled properly and that the project stayed on schedule. He was always responsive, transparent, and genuinely cared about the quality of the work. What gave us extra peace of mind was that he even came by personally after installation to check our attic and ensure there were no leaks around the HVAC exhaust.
The crew worked efficiently, kept everything clean, and the final result looks great. It’s not always easy to find a contractor you can truly trust, but this has now been two very positive experiences with Main Street. I would highly recommend them to anyone looking for reliable, high-quality work.

Michael and his team are prompt, professional, knowledgeable, and dedicated to building the best decks and patios. Michael was easy to work with during the planning stages and had great ideas for design and layout for our deck and patio. His construction crew was diligent with getting everything measured and installed correctly. From material delivery, to construction and cleanup, everything went very smoothly.  Michael was very responsive via texts and calls during the project. Highly recommend this company and will use again in the future for other projects!

 Trustindex verifies that the original source of the review is Google. Mike and his crew offer everything you would want in a home contractor. They're prompt, dependable, and efficient, arriving when they say they will and getting right to work. Mike's estimates were reasonable and accurate, and he was very good about keeping us informed when unforeseen developments required revisions. The jobs Main Street did for us — deck footings replacement and deck repair/repainting — were done promptly and efficiently, at a reasonable cost, and we are very satisfied with the work. We heartily recommend Main Street.

 Trustindex verifies that the original source of the review is Google. Michael and Main Street Home Improvement did a fantastic job with our Home Improvement project. We had several contractors bid on the project but Michael really spent a lot of time listening to what we wanted and then came back with a better price and very insightful plans not just in the beginning but throughout the project.  He was extremely easy to work with, returned or calls and texts quickly if we had questions or concerns, and the finished product looks fantastic. The crew had great attention to detail, they finished the project on time and actually under budget so we were able to complete a few extra improvements. Highly recommend Michael and Main Street Home Improvement!

 Trustindex verifies that the original source of the review is Google. Mike did a great job rebuilding our deck and patio.  Mike's crew demolished our old patio and created a larger patio and walkway.  He created a rock drain that works well and looks great.  Mike came up with some creative solutions to make everything work around our older house.  Mike's crew also handled repointing some bricks and fixed some broken bricks in a garden wall.
Mike's price was lower than the other bids, and he was able to work around our schedule.
Mike's crew was even able to quickly rebuild our backyard gate so we didn't have to worry about our dogs getting out.  Kudos to Mike and his crew.

 Trustindex verifies that the original source of the review is Google. I was so lucky to work with Michael and his team this spring on our deck replacement! Not only was Michael so helpful and accessible during the process, the project was completed on time and on budget. We love the deck that he designed and his team expertly installed this summer.
Great group!
