"We had an outstanding experience with Owens Corning Basement Remodeling from start to finish. The entire team was phenomenal—professional, communicative, and truly dedicated to delivering high-quality work. One thing that really stood out was how quickly they got started. There was no unnecessary waiting, and they stayed on schedule the entire time, which made the whole process smooth and stress-free. A special shoutout to Carlos and Luis, who worked tirelessly on our basement. Their craftsmanship, attention to detail, and strong work ethic were obvious every single day. They took great pride in their work, and it absolutely shows in the finished result. We couldn’t be happier with how everything turned out. If you’re considering a basement remodel, I highly recommend Owens Corning—they exceeded our expectations in every way!"

"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!"

"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 />"

"Jane was on time, friendly, and knowledgeable. We took a good look at the property and she made some great suggestions for how we might want to remodel. She also listened carefully to our needs and our reasons for remodeling. She gave us some good ideas for how to fit a shower into a downstairs half bath without needing to bump out. When we are ready for our large project, we would go back to Jane to draw up the plans.  "

"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."

"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."

FAQs for basement remodeling projects in Lexington, 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.
