We are capable of working with a budget for any project, whether it be for a home, office or commercial property. From painting and flooring to renovations and full custom remodeling, let our expertise and experience produce your vision.

"It was a great experience working with Vick. There was no way we would've been able to quarterback the project and have it done as quickly as he was able to, so 100% worth hiring him. Our project was gutting the kitchen and expanding it into the dining room (eliminating the wall to create one big kitchen), painting and new flooring throughout the 1st floor. He was able to get us on schedule QUICK and was good at communication. The job was subcontracted out, but the people Victor brought in were reliable, friendly, and hard working. Demo started 3/1 and the project was completed 5/3. A majority of the time was waiting on the appliances, then cabinets, then counters to come in so really all out of Vick's control. Once they were in though, Vick was quick to get the crew working again."

"It was amazing 🤩 I made a call to MAS and Harold and Lauren were at my home the next day. Harold, Pete and Gabrielle were extremely hard working and so courteous and such a joy to work with!! I actually was so pleased with the deck that I asked for a quote on vinyl fencing. I would strongly recommend this company for any work needed. It means so much when the actual owner of the company comes and does the work alongside his employees. I did happen to see one horrible review from someone who was 100% 😑. It was actually the only bad review so clearly it was not the fault of MAS but rather the idiot that posted such an incredibly inaccurate and incorrect review. I will definitely recommend this company to my family and friends and take it from me, I can really be a PITA when things are getting done at my home but not once was I ever meant to feel like I was being a PITA. The customer service skills of Harold and Lauren and their team is remarkable!!!"

Addition to existing structure building services FAQs

How far you can push a room depends on the structure you choose. A cantilevered bump-out can extend 24 inches before building codes require its own footing or foundation. Anything longer needs engineered support and a permit. Check local codes or consult with a structural professional before finalizing plans to ensure your design remains safe and compliant.

Most bump-outs are completed within one to four weeks, even with minimal electrical, plumbing, or HVAC work. Their compact size means less demolition, simpler inspections, and fewer weather-related delays compared to a full-scale addition. Your contractor can provide a more precise timeline once they have determined the scope, materials, and permit schedule, but plan on having the extra square footage ready in approximately a month.
