"To say it went perfect would be an understatement. We could not be more pleased with the craftmanship, the staff, the materials, and the professional construction we had done from this company. The photos of both bathrooms do not even do it justice because we can't capture the entire room with one photo. We have never had such amazing construction done by any contractor in the 32 years of home ownership, prior to this company. They do it all. Indoor, outdoor, heavy construction, light construction. They had to relocate HVAC ducts, plumbing, electric, and move some walls. They are a one-stop shop!! Prices were extremely reasonable."

Customers say: True professional

"Devin Nasvaderani (Marel Homes) is, without a doubt, the best contractor with whom I have ever worked. He came into a job that had been royally screwed up by a prior contractor (see review of Stevenson & Sons). He thoroughly inspected the property, prepared a detailed bid, gave us advice on the most important items and delivered a bid that could work with our budget and the existing lender requirements. His entire crew were professional and consciencious. Devin delivered on time, on budget with high quality work. He kept us informed throughout the process. The portico he built is frequently the subject of compliments by our neighbors (and people just driving by). We will use Devin to continue improving our home. He took a nightmare and turned it into the dream home we had hoped for. If you need a great contractor to remodel your home, call Devin at Marvel Homes (the name says it all).

"We are ecstatic about how our basement renovation turned out! When my husband and I met Chris in March 2021, he was very professional and knowledgeable about what it would for our project. The cost estimate he provided was reasonable and we were able to stay in budget. His team was polite and had good work ethic. Chris was very engaged in the entire project and kept us aware of progress and delays. In addition to the project, they included a few other items that really helped us (I.e., electrical socket in the front of house, cable wiring in the living room for better signaling throughout the house)They did great work and we will be using their services for future projects! We would highly recommend The North Star Companies!"

"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"

"Could have been any more impressed with the pleasantness, punctuality, professionalism and end product. We had a old deck with a huge tree in close proximity to the house. The removed that without even a piece of bark falling on the roof. Having someone that knows what they are doing and are trustworthy is the best combination ever. Deck was huge and they build in storage underneath that was water proof as well. Solid as a rock."

Every project begins with understanding what you want to achieve. Whether you’re updating an interior or planning a larger transformation, the first step is discussing your ideas, priorities, and the possibilities for your property.\n\nDesign gives those ideas direction. Planning and permitting help clarify the requirements, while construction brings the agreed vision to life.\n\nOur proposed approach connects these stages, giving you a clearer understanding of the decisions ahead—from the initial conversation to the finished space.

"We hired Green Studio Builders to build a two-story addition on our home. The addition included a master bedroom suite, a kitchen, and a renovation of the existing space to match the new part. We also ended up digging the basement under the addition but have yet to finish it. We interviewed six builders for the job. Chris (owner) was by far the most realistic about time and money. Most were saying the job would take around 4 months. Chris said 6. He finished in 5. Chris does design/build. We already had architectural drawings done in advance but the first step Chris took with us was to improve them. Chris assigned us a foreman, who we had day to day contact with. The communication was great, the workers always respectful and the job site was cleaned up daily. We have two young children and we lived in the house throughout the construction. The team made sure to time the job appropriately to lessen the impact on our lives. For instance, they moved us out of the upstairs and worked up there through completion and then moved us back up there and worked downstairs. When it was time to demolish our existing kitchen we got plenty of warning as they prepped the area and worked with the cabinet makers on the delivery date to leave us as short a time as possible without a kitchen. We were amazed that we were without a kitchen for only three weeks as we have heard horror stories about kitchen renovations from our friends. Chris's team worked six days a week, every week. All of the workers are his employees with the exception of the plumber and the electrician, who were subs that he uses on a regular basis. The process was fairly seamless on our end. They worked with the county for inspections and allowed us the peace of mind to live life as (somewhat) normal for the duration. Another huge perk of GSB is that Chris's wife, Nicoletta, who also works for the company, helps with the interior design. She helped us select tile, paint, and fixtures that would match our style and she has an excellent eye. All in all, we were extremely pleased with the company, the process, and the final product! The work is top notch and we are constantly showing it off to friends (who are equally impressed). We will certainly hire GSB again when we are ready to finish our basement. Chris and Nicoletta are wonderful people and run a top notch company with excellent skills and service.

"Installed 4 ceiling fans and 1 chandelier. Excellent service, done in a timely manner. Arrived punctually and began work promptly. Used drop cloths to catch debris and cleaned up nicely. Friendly, polite and respectful. Price was as quoted and very reasonable for the service provide. Very flexible and even installed 1 additional ceiling fan for an additional fee. Worked thru a couple of challenges with bad parts supplied by the manufacturer with no problems, to get the job done. Good quality work, professionally done. Highly recommended."

"I originally hired Daniel to perform a first floor kitchen remodel which included opening up the first floor with a more open concept floor plan. And adding a kitchen island. The project went smoothly and I was so taken by the final look that I had him come back to update three bathrooms, as well as, a complete remodel the basement. The house now has a more contemporary/ modern appearance and I receive compliments often. His price points for the individual projects were fair. I found him to be not as pricey as some and a bit higher than others. The workmen were polite, cleaned up daily before leaving and very repectful of my wishes. If I had to list a con it would be that one or two of the projects were not completed on schedule. Each being off by about a week. Overall, I would hire him again and have referred him to several friends and family members."

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