"Allen Metcalf is an artist. He doesn’t just build something, he creates. This is the second project he has done for us and replaced a small deck outside our sunroom that as rotting. Allen pointed out that more than one piece of structural wood needed replacing. He also pointed out where the deck and addition weren’t properly anchored to the house. He submitted a 14 page estimate detailing everything he would be using and doing. If you want the best and don’t mind paying a few dollars more for his precise, professional, and well crafted work, you need to contact Allen."

"Got a great, thorough design from EDB. When it got time to do the build we couldn't get to an agreeable price, but the team was friendly, helpful, and professional throughout."

"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"

"From the start to finish, we were very pleased. When Custom Home Creations Partner Garrett arrived, we were impressed with his thorough assessment of what work was needed and what we wanted done. His proposal was right on point with what we expected. The construction team arrived on time, were professional and they efficiently completed the project within the time frame we were quoted. We now have a beautiful, safe and secure pressure-treated wood deck and stairs and we look forward to staining it in early Spring. Here's our "Before and After" photos! We would definitely hire and recommend Custom Home Creations for future projects!"

"We used PI Kitchen and Bath in Frederick to completely remodel our master bathroom. We wanted to update the entire space and make it feel more comfortable and modern, and the finished bathroom is exactly what we were hoping for. There was an unexpected issue during the project that required some additional attention. Our project manager was very responsive and handled it right away. For us, that was actually one of the things that stood out about the company. Remodeling can have surprises, so seeing how a company responds when something doesn?t go exactly as planned is important. They made sure it was corrected properly and kept us informed. The tile work and overall finishing look beautiful, and we?re very happy with the quality of the completed bathroom."

"We had wanted a screened in porch for a while and began to talk with contractors in Spring 2019. We felt very comfortable after talking with Goliath that not only were they capable and in the ballpark of the other estimates, but that they were truly committed to quality work. We began working with them on the designs and specifications, and we had lots of questions because although we knew generally what we wanted, there were lots of details and decisions to be made. They struck the perfect balance of making suggestions, pricing out options, and providing guidance without dictating changes. We changed our minds several times about this or that and they were always amenable. I should note that the job was not only the addition but replacing two large windows in the back, one with a custom sliding door and the other with 3 windows. The addition included a deck, an outdoor gas fireplace and TV, so they had to run electric and gas line. They also replaced our roof and gutters. There were challenges (the shop we bought the windows from dropped them loading for delivery, the inspections were, at times, nightmarish), but Goliath stayed calm, made adjustments, and pushed through. I should also say there were many crews working and all were extremely professional and respectful. We would definitely use Goliath again and would highly recommend them to others."

"They were very hard workers and very polite. Their work was excellent. I am very pleased with the result. They had to replace drywall and re-secure the remaining drywall in a large two-car garage. They taped, sanded, primed, and applied two coats of Sherwin-Williams paint. It looks like new again."

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