"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."

"We recently hired Lancaster Home Remodeling for a home improvement/shed finishing project, and we couldn't be more pleased. They are incredibly responsive, always available to answer questions and provide updates. Their creative ideas truly transformed our shed. What sets them apart is their hands-on approach—they do most the work themselves, ensuring high quality. Plus, their flexibility and self-sufficiency made the whole process smooth and stress-free. Highly recommend Lancaster and we would definitely use them again!"

All City Remodeling not only met but exceeded our expectations. Without a doubt, weâ ll be calling Jimmie for any and all future projects!"

"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. <br /> 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.   <br /> 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. <br /> The rooms turned out very well.  Would use them again in the future. <br />"

"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."

"After discovering black mold creeping up the sheetrock along my basement wall we found that we had a hidden leak that we thought came from the patio door above. The home owners ins adjuster told us to hire a contractor and to brace ourselves because he believed the damage was extensive. He was right. We hired Matt Palmer (MMP Construction) and he gave us the devastating news that the entire lower half of the house was rotted from water damage due to an improperly flashed deck that ran along the back of the house.  I desperately wanted to save the deck, (54X12). It was a difficult task, but Matt was able to save it. <br /> Matt worked diligently, stayed in contact with me (I was not able to be present during the day) and in the end gave us a great product. Matt was not only skillful, but very knowledgeable, creative, and professional. I will definitely be hiring him again. <br /> <hr />"

"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."

"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."

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.
