"Bob Ayotte is by far the best general contractor my wife and I have worked with. He is professional, he is a great communicator, he delivers what he promises, he takes the time to discuss and educate you on the work being performed and, most of all, is just easy to work with. He gets it - not all of us are in this space. And he does what it takes to make sure you understand everything that's going on so your investment is absolutely worthwhile. The kitchen is a dream and the basement looks fantastic. Thank you!!"

"When we started our plan of remodeling, the first thing we did was the complete roof replacement including kitchen vent & duct pipe installation to the roof, and new installation of attic ventilation. MMP did not only completed it just as agreed but also very efficiently. The crews were friendly, professional, and careful. The jobs were carefully managed and implemented effectively. I was impressed by Matt, who is the manager, and he does an outstanding job in managing the crews and the progress of the situation, and the communication was clear and always to the point. We then moved to initiate a search for a contractor of two bathrooms remodeling after completing the roof and attic vent, MMP was one of the many candidates. Matt has had not only the best idea and proposals but also shown an impressive & professional sense of evaluating the project accurately, including the possible structural modification as well as a competitive estimate of the cost of the build. His proposal included a rebuild of a wall of the bathroom to expand another one adjacent to it. Matt accepted to use my schematic design image (made with a software tool) and a spreadsheet list of the fixtures that I created - as many as fifty items including TOTO, Grohe, American Standard, Panasonic, and IKEA - to start the job (later changed some of them due to local plumbing code compliance) After beginning the bathroom remodel project, Matt shared what jobs will be done with us timely and efficiently via text so that we feel comfortable enough in knowing what is going on while living in the house of dust & noise from remodeling. The crews, Zen and Mark, were very courteous, extensively experienced, reliable, and friendly with excellent communication, sometimes with songs of 80s rock music. They ask me when more precise specifications are needed and notified me when they feel advance notifications are required. When a change is necessary due to inspection, they informed me and clarified what and why. I have never felt uncomfortable in living together with the remodel job which has lasted over four months. The completed two bathrooms were stunning, just as I imagined. Matt, Zen, and Mark have proved their strong & thoughtful expertise and lived up with my request patiently until completion. Great job. A home remodeling project cannot be successful without having a trusted partner, and my experience with MMP has led me to be glad to share my confidence that MMP has a credential to become your reliable partner to manage a construction project together."

"We hired KATS Construction for a Kitchen dining room remodel with removal of walls. Tom referred us to a very reputable cabinetry company who did an awesome job as well. The contractors were very professional, courteous and prompt. Tom was always in communication as to schedules of his crew, and available to answer any questions or concerns we had. He took care of any permits and approvals that were needed. Due to personal emergency we needed to stay home through the construction since day 1. Tom and his crew all went above and beyond to make sure we had what we needed to stay in the house. We are very pleased with the outcome. It feels like a brand new home. I would highly recommend KATS Contruction, Tom and his crew, We thank them all."

"Paul O'Regan is a seasoned pro and does incredible work. In all fairness, the company probably deserves a solid 5 star rating and I'm just hyper-critical. I will absolutely be following up with Paul for a garage addition to my house within the next year and for some other projects. Our kitchen remodel came out amazing. Paul took down a wall and installed new cabinets for us. He patched the wall beautifully and gave us critical guidance and advice. An absolutely awesome experience and highly recommended."

Basement Remodel questions, answered by experts

Installing a bathroom in a basement isn’t a project for most homeowners. Many parts—plumbing, electricity, and carpentry—go into this project, each requiring expert-level knowledge and tools. One miscalculation can lead to very expensive repairs. Plus, some homeowner’s insurance might not pay for damages caused by a homeowner DIYing this project. You can protect yourself by allowing the pros to complete this job for you. 

Common mistakes when finishing basement walls include neglecting proper insulation, insufficient moisture management, and poor ventilation. Not addressing these issues can lead to mold growth, water damage, and discomfort. Additionally, inadequate planning, improper framing, and rushing the project can result in subpar outcomes. 

It's essential to follow best practices, seek professional guidance if needed, and prioritize thoroughness and attention to detail.

The difficulty of adding a basement to an existing house can vary depending on the house’s location, the size of the basement, and the type and condition of the existing foundation. Adding a basement is a job best handled by the pros, so you’ll need to enlist professional help for this project.

A walkout basement is considered to be partially below grade because at least one wall is entirely exposed. In some cases and in specific municipalities, inspectors and appraisers will still count walkout basements as below grade, which means the space can’t serve as living space or be rented out. If you intend on using the area as living space or a separate apartment, you should check with your local building department to make sure it’s legal to do so.

Yes, most general contractors require an initial down payment, typically between 10% and 25% of the total project cost. This upfront payment helps cover the costs of materials, permits, and subcontractors. The remaining project costs are usually billed after specific project milestones are reached or on set completion dates, as outlined in your contract. Be wary of contractors who require a significant deposit of 50% or more upfront, as this could be a red flag for a scam.
