"After doing much research I hired John Krause Construction for a very large project: Sunroom addition, deck, patio, front hardscape and landscape with design of my entire house and yard! John came out personally and was very honest and his pricing was fair. They did an amazing job taking my vision and making it a reality. The crews were efficient and responsive. I will use them in the future."

"AES renovated two bathrooma and a half-bath for us. They have a thorough process and a caring, responsive team. Our project began with a detailed review of our wish list and cost estimate. The designer took us shopping for beautiful modern finishes that fit our style and budget. The installers/builders are highly skilled, worked efficiently and perfectly, and checked with us throughout the process if details needed to be ironed out. The Project Engineer stopped by several times for status checks both during the job and after completion. At the end of the job, we were left with an amazing transformation of our rooms into beautiful, functional spaces that are structurally superior to the original build."

"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"

"The Owner of the company was also the sales person, allowing him to relate to the customer directly (We liked this). He was on the job while it was being done and did a walk through at the end (yes I was on the roof), he shows pride in the crews work and quality. The crew was professional and respectful, worked hard and finished the job in one day - Good Job Guys. The job site was cleaned up when finished and looks great."

"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 Severn, 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.
