"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."

"The project went great. On time and within budget. John and John did all the work necessary to remodel a master bathroom, a half bath and a laundry room. This included all the demo, floors, walls, cabinets, plumbing, electrical, shower, tile, painting, etc. Excellent job and we will definitely use them again for our next project!"

"This was our first time using them. We found them on the internet then gave them a call to put an addition on. Everything turned out beautifully. When we called to get pricing and talk about the job they were very friendly and accommodating. They made the process seamless! Their pricing was very reasonable. The workers were prompt, polite and professional. They were very courteous and they were respectful of our home. They also did a great job of being tidy and cleaning up after themselves! I will have to remember next time that remodeling is a bit of a noisy process, but I can handle the noise for such a beautiful outcome! You will not be disappointed!"

"We had the most amazing experience with our basement remodeling. It was done quickly and efficiently. The end product was exactly what we wanted, gaining additional space and comfort. We utilize the new space as a den for our family to play games and watch movies. It’s our new favorite spot in the house. I recommend this company to anyone looking for a basement remodel."

"We hired Tom for a kitchen & half-bath remodel in 2019. As with all remodeling projects, especially a kitchen remodel that disrupts your life, Tom was wonderful at communicating and kept the project on time and on budget. Tom stands behind his work and quickly remediated any issues (which are always inevitable with these projects) and we can absolutely say that we are still 100% satisfied a year later. We completely trusted Tom to make our kitchen remodel dream come true and would hire him again should another project come up!"

"I would not hesitate for a second hiring Horsman Builders for any of my house projects or remodel, in fact that is what I will do from now on. I was nervous starting a project having to handle things on my own but Tim made me comfortable with a detailed estimate, answered all my questions, kept me informed about the work, the site was always clean and the result is awesome, my neighbor was commenting on how great it is just checking it out from a window. Fair price, excellent quality and great customer service. A+"

"I had a very satisfying experience with my basement remodel! I was referred to Peter Rousseau and immediately the estimate was on the Button. I added some other tasks as well as upgraded materials to really make the basement a family room and he was very fair about charging me for these extras. I love my new basement!"

"We hired All Work Construction to update our master bathroom, including marble floor and shower walls, custom niche, new tub, vanity with marble top, electrical etc. I'm a designer and perfectionist, so this job was rather complex, with a few minor hick-ups. All Work Construction did an amazing job overall, Vlad and his team were very responsive and pleasant to work with. We love our new dream bathroom! Would like to hire them again, to remodel our kids' bathroom :)"

"Sean and his crew are truly Professionals within this Industry. Courteous, Friendly, Responsive and produce Excellent Quality Workmanship. By far, Sean and his crew are the best I have ever had the opportunity to hire for a major construction project that resulted in a comfort level knowing that everything was being handled properly. Construction is a challenging venture when putting on an Addition to an existing dwelling. There are many obstacles and challenges that can be faced throughout the project and within the home. Sean and his Team went over and above and addressed each challenge professionally and with timely resolution. I couldn't ask for any better service and results! The addition came out beautiful, I have an awesome Garage and my Wife is ecstatic with her new Mud Room and Pantry! I would recommend Hand and Some for any project that you may need."

FAQs for addition and remodeling projects in Windham, NH

The proper sequence of a kitchen installation starts with laying the foundation and structural framework.

A professional kitchen installation contractor can coordinate each component of your project to minimize the timeline and maximize resources.
