Our reputation is based on service, safety, and quality, regardless of how large or small the job.

"I got several proposals from different companies to address my basement flooding and foundation issues. Caleb, with Classic Home Advisors, was the best from the very beginning. He understood the issue and explained to me a few options available to me to address the issues with my basement flooding. The proposal was clear and indicated exactly what and how the work was going to be performed. It took 1 week from start to finish and throughout the execution of the project, I was kept informed of their progress. More important than everything, I already can tell that the repairs to my basement were successful. We have had 2 main rain events since they finished the work and the basement is dry. The foundation repairs looks solid. Iâ m extremely happy with the final outcome of my basement project. Classic Home Advisors did an outstanding job. I have no reservations in recommending them for any of your water proofing projects, or for that matter, any home improvement projects."

Misha's Home Improvement, Inc., has been in business for more than 16 years and all of our employees are skilled European craftsman. Call us for your entire wood and ceramic tile flooring needs!

"After having gone through four contractors who made big promises of written estimates which never materialized, my expectations of this company were pretty low. But when I reached out to Misha's Home Improvement I received a prompt and courteous reply. We made an appointment to meet at my house. Misha arrived at the appointed time (to which I arrived late) he walked up to meet me, holding a clipboard and measuring tape in hand. We shook hands and I realized right away that I was dealing with someone of a higher caliber. When we walked through the house I stated my requirements only partially whereupon Misha offered ideas and options. Every room. Methodically. Misha took measurements and we parted company. I had no appreciation for how much information he was taking in during our visit. A few days later a detailed estimate landed in my inbox. Room by room. Item by item with materials and labor costs and a detailed drawing of the entire layout of the home with precise measurements. No BS. I was impressed. We agreed upon a start date and a pattern emerged. This guy and his extraordinary team of guys came to the house every day (sometimes on weekends) and proceeded to embark on a Whole House renovation. Craftsmen all. Courteous and respectful to a man. Windows, bathroom reno, kitchen reno, recessed lighting. wiring fixes with attention to code, basement tile, patio doors, drywall repair, custom closets. Change orders written and agreed upon - in advance. No surprises in our agreements or fees. In fact, where warranted Misha refunded me for materialis/labor that were not needed. Misha and the guys have completed the job and I have to say that I will truly miss them. True craftsmen. I will absolutely recommend this company of men and the man who runs this enterprise. I got very very lucky."

We pride our company on reliability, great communication, integrity, and quality work. We strongly believe in giving our absolute best in all of our projects no matter how big or small. We are experts in our trade and will always keep you educated on your particular task or project. We look forward to earning your business!

"All the people at Elevate Design and Build were amazing and a pleasure to work with. We doubled the size of our house including tripling the size of the kitchen, knocking out walls to create an open floor plan and added a three car garage with home office over the garage. They even recommended modifications to our original blueprints which were excellent. All their workers friendly and did a first class job. Went totally above and beyond our expectations. One year later we have not had one single problem with any of the work. Total integrity. If any issue came up, the company absorbed the cost - not the customer. Everything they did was done perfectly. We didn't have a single issue or complaint during the entire process. I give them my highest personal recommendation. I would never use anyone else."

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

Building an in-law suite takes between two and seven months. Converting an existing basement, attic, or room can be done in about two months. Constructing a new addition or detached suite often takes four to five months for construction, plus one to two months for permits. The bigger the suite, the longer it will take. 

Yes, you can build an in-law suite in your backyard if you meet local building codes and zoning regulations. An in-law suite often occupies 300 to 800 square feet. Be sure to follow size restrictions, utility separations, and entrance requirements. Hiring a qualified contractor ensures you meet all regulatory requirements because they can pull permits, double-check local code, and gather other skilled pros to work on your suite. 

An in-law suite is a self-contained living space attached to—or detached from—your main home. Expect a bedroom, full bath, and a kitchenette or compact living area. The setup gives relatives privacy, doubles as a potential rental, and can lift your property value. To qualify as a legal dwelling, the suite must meet local building codes and zoning rules.
