"We hired General Remodeling Group to renovate our DC home and add master bedroom and mudroom additions. They handled everything from the design and permitting (via their architect), to building the foundation, framing, additions, remodeling a bathroom, widening hallways, installing flooring, drywall, HVAC, electricity, plumbing, installing pavers outside and pouring concrete driveway, installing a wheelchair lift, and more. They handled unexpected setbacks well, communicated effectively during the project, and finished the project on-time and on-budget. I would definitely hire them again, and recommend them to anyone doing a home renovation or addition."

"I have used JW Home Improvement in the past and contacted them for an exterior painting/repair project. Josh, the estimator, was on time, walked through some issues he found with my exterior (wood rot and replacement of siding on the outside of my gas fireplace due to weed wacker damage, and leak in same area) in addition to the painting. I had a two-person team (Thomas and Matthew) for two days to complete the work. They did a fantastic job: kept me updated with any changes needed to complete the work, were always punctual, friendly, and professional; and cleaned up the area after completion. During this time of social distancing and trying to stay safe with COVID-19, everyone I dealt with in person (Josh, Thomas, and Matthew) went up and above to ensure they did what was necessary to maintain everyone's safety and completing the work very professionally. I will remain a very happy repeat customer and have already referred them to my NextDoor App community when someone was looking for a contractor to do exterior painting."

"United Cabinet Store created beautiful custom pieces for my kitchen. I decided to remodel my kitchen and replace the old cabinets. They were no good. I had a specific idea in mind for my new cabinets and United Cabinet Store created exactly what I wanted. When it came time to install them, their team was quick, efficient, and friendly. They were done in no time, allowing me to move on to the next step in my renovation. I highly recommend them to anyone who needs professional cabinet service."

"Omar’s team added insulation, dry wall as well as painting and recessed lighting in an attic office that had lots of weird angles and was very hot to work in. They worked quickly, asked for input and were just very nice guys. They kept me updated on their progress and they stayed within their cost estimate. Omar always does a good job from small to other tasks. And provides fair and upfront pricing."

"This contractor is wonderful. The team was efficient, understood what I wanted and fulfilled my vision. I can't say enough good things about the way this project went. They completely remodeled my family room, and when I asked for additional work near the end, they quoted me a reasonable cost to add it to the original work"

"I love my basement now! They removed all of the asbestos flooring, adhesive etc. and installed my new floor in 2 days. The employees were very respectful and worked efficiently. They had said 3 days but they hustled and did it in 2."

FAQs for addition to existing structure building service projects in Washington, DC

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.
