"Joe and his team did an incredible job, the work was excellent and I appreciated the workmanship and the creative trouble-shooting (it's an old house!) to get excellent results. Everyone on his team was great: skilled, hard-working, friendly, and kind/respectful. Pricing was very reasonable and allowed me to upgrade items like appliances without sacrificing the scope of the remodel, quality, or workmanship. My house is transformed and I could not be happier with the results."

"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."

"Khaled did a major renovation for our property, including kitchen, bathroom, basement, living room and deck. The house needed upgrading of heating system, electrical and plumbing. Khaled came highly recommended from our realtor who said that he did excellent work for her. From the moment we meet Khaled it was apparent he knew his stuff. He walked through the house examining the structure and construction, pointing out defects, areas of improvements, and possible approaches. When we started the actual demo and rebuilding, his crew was diligent and very capable. Khaled takes pride in his work and is honest and reasonable and I suggest asking for his input as he always has good ideas and vision. In this age of cost cutting, sloppy workmanship, and lack of integrity, Khaled stands out as an honest contractor who cares about his work. He doesnâ t cut corners and is through and careful. His crew is also trustworthy and hardworking. Bonus points to Khaled also for being funny, smart and charismatic. Yeah this is a paean of praise but in this case well warranted. Five stars for this excellent contractor."

"Jay and his team at Discovery Home Improvement were outstanding in every way - friendly, professional, hard working . . The project was primarily exterior painting of a five bed -room house and carpentry work as a preliminary to the painting - a garage window and a basement window needed replacing, along with exterior woodwork and window sill repair. We are incredibly happy with the results and hope to have Jay return to work on the interior of the home."

"I used Remodel Or Renew Home Improvement to replace a door I had installed not long ago. I had water coming in and the old contractor was nowhere to be found. The owners Tom and Mike came to my house identified the issues and had a crew here the next day. I cant recommend this company enough. I was loosing sleep with water coming into my basement. I have new confidence in good people to do great work! Thank you Remodel or Renew! Exceptional service at a reasonable price."

FAQs for basement remodeling projects in Charlestown, MA

Finishing a basement turns unused square footage into livable space and returns up to 70% of what you spend when you sell your home. Beyond that resale boost, you gain a playroom, home office, or guest suite you can start enjoying right away. That mix of daily comfort and solid return on investment (ROI) makes basement finishing one of the smartest upgrades you can tackle.

In some parts of the country—especially lots on swamps, high water tables, or other wetlands—local codes prohibit basements. Saturated soil puts constant pressure on foundation walls and lets water seep in faster than any sump pump can handle. 

If your property sits on waterlogged ground, building on a slab or crawl space is often safer, more affordable, and code-compliant.

Most basements wrap up in four to eight weeks. Framing takes three to five days, with electrical and plumbing rough-ins following over the next week. Add five days for drywall, two to three for flooring, and another week for paint, trim, and punch-list items. 

Delays can happen if materials run late or your contractor’s calendar is packed, so build in a little cushion when you plan.

Whether a finished basement counts toward your home’s official square footage depends on local rules. Many areas only include below-grade space if it has code-approved egress, fully finished walls, ceilings, and floors, plus consistent heating. 

Check with your local assessor or building department before you start; meeting those standards can affect taxes, appraisals, and resale value.

Building codes require a checklist: dedicated heat and electrical service, a code-approved stairway, and at least one egress window or exterior door. Walls, ceilings, and floors must be fully finished and meet insulation, ventilation, and fire-separation standards. If you add a bedroom, you’ll also need a closet, proper clearances, and safe exits. If you change the layout later, be ready to update the space so every new room still meets today’s code.
