"Leo and his crew were some of the most professional painters I have ever worked with. Leo is incredibly responsive and worked with our budget for a full exterior repaint of our house. His team is extremely detail oriented, conscientious, kind and beyond professional. They meticulously cleaned up everyday and were prompt with arriving and staying for the entire day. The job was completed in exactly the timeframe provided and we couldn't be happier with the final result. I would recommend Leo and his team to anyone looking for home improvements - they are outstanding!"

"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."

"Pedro and his team were excellent. They were professional and timely, hard-working and meticulous, and trustworthy. Best of all (at least for me), is that Pedro is VERY responsive and his team is assigned to get your job done and done correctly. They show up on time every day, and were willing to work late into the evening to hit the project milestones. Pedro was 100% clear about the costs, and he made sure I fully understood the areas where the costs were not known or where the costs could possibly change. For example, he said, "If you open up this wall, I'm not sure what we are going to find." I told him to proceed and his team opened up that wall and found that the previous contractor had installed literally zero insulation. Pedro met with me, reviewed what his team had found, went over all of our options, gave me his recommendation, and only proceeded when I completely approved the additional work that would be done and the additional cost entailed. Pedro is a true partner and his team does great work. I cannot recommend them enough. My wife and I have already booked them for another job renovating a first floor porch and creating a roof over the open-air second floor porch."

"Highly recommended!! Liam did a wonderful job with my closer repair. The room was gutted to the studs from a water leak and Liam put it back together beautifully. I’m very happy with his craftsmanship and excellent work. He was courteous, professional, and very skilled. I’d highly recommend his services!"

"Working with John and his team was an absolute pleasure. I truly can't speak highly enough of their professionalism and dedication. Kim’s communication about John and the rest of the team was also outstanding—clear, timely, and helpful throughout. John stood out for his flexibility and responsiveness, always ready to answer questions or consider suggestions. Fortunately, our project only encountered a few minor curveballs, all of which were handled smoothly and confidently. What impressed me most was John’s pride in his work. One day, he noticed a small detail that most wouldn’t have caught—but it bothered him enough to rebuild it until it was perfect. That kind of care and commitment is exactly what you want in someone working on your home."

"Rich and his crew were fantastic- very informative, accommodating to our family and went above and beyond. I originally hired for 2 bathroom projects, and added more projects along the way. I’m a very happy customer and would use 3G’s again for my next home project. "

FAQs for basement remodeling projects in Belmont, 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.
