"I hired Silmac construction to remodel my basement. They put in a three-quarter bath, kitchenette, and finished the rest of the basement. This included cutting foundation for full size windows, putting in a new zone for heating and cooling system, and all the plumbing and electrical work needed. They were very professional and did an excellent job. I have gotten many compliments on our basement and I will hire them again to do work on my house."

"I recently had a basement finishing project completed by WR Builders, and I am thrilled with the outcome. They turned my unfinished basement into a beautiful living space that my family loves. The crew was friendly and professional, making the whole process stress-free."

"We highly recommend Lancaster Home Remodeling. They exceeded our expectations in every way: super-responsive communication, high-quality work, fantastic support during and after the project, and reasonable pricing. From the initial design phase, John offered thoughtful suggestions/advice and would point out potential issues. We found it invaluable. During the build, Kim responded very quickly to any emailed questions and even reached out to let us know if no one was working the next day so we could keep our dog home and save on dog daycare costs. A small example of how they focus on the homeowner in their plans/decisions. During the build process, we had water coming in from our bulkhead - from outside not part of the remodel. John went out of his way to try and stop the leak even though he didn't have to. He went above/beyond multiple times. We absolutely love the way the basement turned out. We enjoyed working with them, and our basement looks beautiful."

"Pedro Quissanga was wonderful throughout the process. The project started out as a porch window replacement with an architect drawing plans, but once we started construction, we discovered that the whole underneath part was rotting and needed reconstruction. Pedro and his crew were hard working, reliable and careful, and his price for all of the work was very reasonable. When something went awry late in the construction, Pedro took it seriously and got people over within hours to locate the issue and fix the problem. Even though the project ended up being much more difficult than initially expected, there were never any unexpected charges and the additional work was at a consistent high level. We recommend Crystal Renovations without reservation and have several neighbors using them now for small-to-medium sized projects."

"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."

"Mostly well.  We purchased the Big Deal for 2 painters for a day which said it would be 2 painters for 9 hours for a total of 18 hours.  They showed up with 3 painters and said their day would end earlier since they would hit their 18 hours sooner with 3 people.  I do wish we had known that in advance, but it worked out.  They told at the beginning that the oil based primer wouldn't have time to dry because it needs to dry for 24 hours, so we had to go back to get latex primer while they prepped.  That was disappointing because everything I read was that the soot should really be covered with oil based primer so that it didn't bleed through.  I wish they had told me that when we were exchanging emails about the job, but maybe I should have known that already.  We had to have the job done that day though, so rescheduling wasn't really an option.  When my husband returned to the store to get latex paint, they asked him to pick up a pack of rollers also.
They did a quality job, painting the ceiling which was probably difficult since the family room had two levels, with part of the room having very high ceilings with skylights, and another part of the ceiling was over a staircase to the basement.  Since we had purchased a deal that was for a specific time frame, they covered a lot with their time, and my husband was set to complete what they didn't get to.  We were happy they were able to prime and paint the entire family room for the most part, and able to prime the bathroom as well.  
They were flexible and worked with us with what to do.  We needed to paint the family room and bathroom and kitchen.  We only wanted to pay for the one day and my husband was prepared to finish whatever was left over himself.  We were hoping they would finish the family room at least.  At some point my husband saw how much time was left, and decided he would rather have them prime the bathroom instead of cutting in along the floor in the family room with the paint (since my husband would rather finish the paint than deal with priming the bathroom himself).  They didn't have a problem with that.
The rooms turned out very well.  Would use them again in the future.

"We had a major remodeling project with a third floor deck new addition to the second floor master bedroom new bathroom new closet. We had eight new windows placed the whole back of the house has new siding and trim as well as corner boards and it looks incredible. The deck was masterfully built where it is incorporated within the structure of the house it is absolutely 100% leak proof and a joy to experience. The project started in late February and finished in late May. James was a wonderful contractor to work with with a great crew and Grainnie made sure that all of the appointments were met and coordinated all aspects of the work. She was a joy to work with; dedicated beyond efficient, she was available and responsive to any issue, and committed to ensuring the job was completed to our satisfaction."

"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."

FAQs for basement remodeling projects in Cambridge, 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.
