"Strong Builders remodeled our basement and added a bathroom. Jack had a clear vision of the project and he communicated very clearly with us throughout the process. Jack also had an amazing attention to detail. The basement and bathroom look great. We enjoyed working with Jack and we look forward to working with him again on future projects."

"Everything went well. We have hired this company for a few jobs now and are never disappointed. They have excellent attention to detail and skilled staff. Everyone is courteous and helpful, taking time to answer questions and consult me on the details. We had our basement walls plastered, trim done, and some custom work on some boxes to cover up exposed utilities. Will definitely hire again for any future projects."

"It went great! <br /> They found the problem right away.  Around the Chimney the caulking had cracked, and they repaired that.  As far as the back of the house with the two bedrooms, they found that the people who installed the roofing as well as the siding had attached their ladders/supports to the roof with nails, and never bothered to re-seal these holes up!!!  Not good since it caused some damage to the ceiling. <br /> Great job!  I would highly recommend again! <br />"

"I once joked to a friend in response to his 'since you are so happy with his work, I may hire him too', I told him, 'you don't choose Vinnie, Vinnie chooses you! Vinnie does the work as if it is his own project. Completely focused, attentive to the details. I liked most of this wor ethic. His quote was one of the most competitive. We interviewed about six different builders all with good ratings from friends or Angie's list. People he works with, electrician, plumber, HVAC were all very professional. Timely. Vinnie came up with this kitchen breakfast bar/island concept. He built it without much of an additional charge to the original quote. Gave us the address from where we could buy a quartz top. That breakfast bar became the central piece of the basement. There was a plain big wall on one side of the basement. Vinne came up with a cost-effective way to turn it into a brick-looking wall perfectly matching brick tiles in the kitchen. He put the kitchen brick tiles in one afternoon, without asking extra on top of the quote. Vinnie guided how best to get custom kitchen cabinets suitable for a basement. He installed the cabinets himself. He had put the crown of the cabinet twice to match two pieces of the crown in color, he did not ask for extra. He helped us choose the best option for flooring for humidity and told us where to find the most cost-effective flooring. He only charged us for putting the flooring down. All this gave us confidence that what he is charging us reasonable, he was not charging us extra on top of the material cost to him since we were buying the material ourselves after making sure that the price/quality was suitable for the project."

FAQs for basement remodeling projects in Southborough, 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.
