"We recently had our kitchen remodeled by Vince and Cindy, and the entire experience was OUTSTANDING from beginning to end. They were not only incredibly professional and skilled but also warm, approachable, and genuinely passionate about their work. From our first meeting, Vince and Cindy took the time to understand what we wanted. They offered thoughtful suggestions and helped us make design choices that perfectly blended style and practicality. The layout they came up with makes the kitchen feel so much more open and functional, and the quality of the materials and craftsmanship is top-notch. They stayed on schedule, communicated clearly throughout the process, and always respected our space. Every detail—from cabinetry and counters to lighting and flooring—was handled with care and precision. Our whole transformation only took 9 days!!!! We couldn’t be happier with the results. Our new kitchen is beautiful, bright, and truly feels like the heart of our home. If you’re considering a remodel, we highly recommend working with Vince and Cindy. You won’t be disappointed!"

"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.
