"Joe, the owner of JD Michael Construction, and his crews are top-notch. When we embarked on a very personal new construction project - the building of a tiny house on our property for a family member - Joe was the first and only contractor that we interviewed, as we felt comfortable with his knowledge, skill, and fair pricing at our first meeting. (It helped that he also came highly recommended by a trusted friend.) Joe’s honesty and integrity were evident from the beginning, and his knowledge and skill in building and coordinating new construction shone through the project every step of the way. Joe hired specialized crews who shared the same attention to detail that he has, resulting in a solidly-built and beautifully-finished structure that not only met every need of our family member, but also added to the aesthetic of our property. New construction is a stressful and long process, but Joe walked us through every step of the way with patience, skill, creativity, and solid understanding of permits, codes, and inspections. I highly recommend JD Michael Construction."

"Job was done as scheduled with additional items repaired as they appeared while the work was being done. Found owner Gary Howard Sr to be very professional and his team led by his son Gary Jr. were efficient and thorough. I had hired them a few years ago for a roof repair I needed and the excellent job they did then prompted me to call them with the above laundry list of home repairs that needed done. Would certainly recommend and hire them again for future needs."

"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."

"You know you hired the right company when the project is completed and looks like it was always there. i couldn’t be happier with my fireplace. Tim and Doug’s workmanship was impeccable. They went above and beyond. i highly recommend this company. Everything from first meeting with Kevin for the estimate to last day on the job for Tim and Doug was perfect. It was nice to have a company do what they say they are going to do show up when they say they are going to show up and everything in between to make sure that we were happy. This will be the only company we use on any other project. No need to shop around we definitely found the right company"

"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."

"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"

"We are very pleased with the firm and the quality of the finished product. We remodeled the kitchen, several other areas of the 35 year old house we had bought including painting, light fixtures, front porch, and bathrooms. The total project cost was about 60-70k. Steve and his team were courteous, professional, accommodating all our requests and changes made as the work progressed. We were managing the project long distance but the firm kept us fully and promptly informed even meeting us in person on weekends since that was convenient to us. Steve is very good and knowledgeable and up to date in his fields. He listens well, is very patient, pays significant attention to detail and provides excellent advice on choices to be made. The project was completed on time and within agreed upon budgets. Have been very pleased with the outcome and the work so far. We would very highly recommend the firm for any type of remodeling work."

"A&N have been wonderful! They did a great job on the bathroom remodel I needed done on a typical cramped 1950s style bathroom to make room for my mother with her walker. They were able to create so much more space and put in a beautiful walk in shower that works perfectly!"

FAQs for addition to existing structure building service projects in Long-green, 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.
