"Jim, Wes, Chris, John, and the entire Elevate Design Build team we've worked with have far exceeded our expectations. We recently purchased a home with serious foundation problems in a second story sunroom addition. The sunroom was the jewel of the house, but the foundation was failing and the room had dropped about 5 inches. We received several opinions about how to proceed - ranging from repairs that would re-support but not level the room to demolition and rebuilding to abandoning the purchase of the property! Jim replied to my online inquiry quickly (and over the weekend!) and met us at the property a couple of days later. He was knowledgable, direct, professional, and very fun to work with. We felt most comfortable with his approach and expertise and were delighted that their proposed budget was more than competitive while still satisfying our entire wish list. They started work ahead of their original proposed schedule and kept us informed at every step. Chris led the onsite work and brought great comfort through stories of past work and his confidence about our approach. Wes (co-owner) was also on the site most days. It's worth noting that this project ultimately happened during the pandemic and we felt that the team took every precaution to respect our health, use appropriate protective equipment, and essentially never enter our home unless absolutely necessary for the project (and with advanced notice). The work itself was excellent. No detail was too small. At one point, it was decided that a change in approach would allow them to spare an existing lower structure slotted for demo. It made the work harder for the crew, but they did it and stayed on budget because they felt it was the right decision for us and our home. While other contractors advised that we'd need to rip out and replace all flooring and windows because they would surely crack while jacking the room to level, Jim said we should and wait and see - maybe we'll get lucky! He priced both eventualities - how much if we were able to use existing vs. if we needed to replace part or all of the interior features. The end result? Jim was right - we got lucky and no windows or tiles cracked! Another excellent piece of guidance that ultimately saved us money and earned our respect but was no financial benefit to the Elevate Team. Our sunroom is level, properly supported, and was less expensive than we budgeted. It is beautiful work, and it has made our house the "dream home" that we were hoping would be possible. In our experience, Elevate Design Build is a team of capable, experienced professionals with buckets of integrity. You can trust them with your home and your wallets. We did and we're thrilled. We've already requested a quote for our next project!"

"A year ago, I hired VKB Kitchen & bath to build an additional master bathroom and renovated old bath. The great president, Paul P Ibrahimov assigned me a wonderful project manager, Will Vusal for my project. I am grateful to have Mr. Will to be my project manager. He and his team did an extremely marvelous job for the additional master bath and old bath remodel They look beautiful and credential. I have given 5 plus stars review for their job through google review. Today I want to recognize MR. Will, the project manager for his continuous responsible of customer care service and help to resolve any problems they have. He is doing his best to uphold the vkb company core values by guaranteeing a two-year warranty of the quality. Exp, my 88 years old mom was waiting for help with the removal of the shower drain filter to clean it. When I called Mr. Will for the help, he came by himself today to help to resolve the problem. My mom is happy she will be able to use her shower ag"

"I bought a home built before 1978 and found that there was some asbestos floor tile in the basement. I reached out to D&H Demolition and they immediately came out to take a look at the project and provided a free estimate. They were very helpful and answered all my questions which made me feel a lot safer about the situation. I hired them and they took care of the work the very next day! Overall I was very pleased with their price and quality of work. Highly recommend!"

FAQs for addition to existing structure building service projects in Windsor Mill, MD

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.
