"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."

"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."

"I have hired New England Carpentry several times for various projects, including facade repairs and repaint on a 3-story multifamily property in South Boston to replacing deck railing and balusters to building out a washer/dryer door frame to fit a larger set of machines. Gil has always been responsive, reliable, and fair. He always worked through what his client wanted but gave recommendations to save cost without sacrificing quality and look. Gil is trustworthy and my go-to for any project. This review is also after some time has passed and I can confirm his quality work holds up. "

"We needed a skylight installed in our bathroom, and MMP did an excellent job--we are very happy with it! The team was friendly and worked quickly and efficiently to get it done before it got dark, and the quality of their work was excellent. Matt was very friendly and nice to communicate with as well, and always responded right away. I highly recommend MMP Construction to anyone looking for great quality work and excellent customer service."

"I wanted a shower expanded. George Mavridis's estimate was very competitive but I hired him because I knew he was honest, quality focused and an open communicator. He has a small crew and excellent subs so he's not super fast. But Mavridis is excellent. One example: The shower needed a new fan, vented through the attic roof. The attic boards were all cut (before my time) in half when insulation was installed. The attic floor was unstable and unsafe. George was very busy but he had his team replace the boards with plywood panels...for 20% less than I expected. Why? Because he wanted to make sure I would be happy when the job was done. I could give 4-5 other examples but you get the point. If you hire George, you'll be pleased."

FAQs for basement remodeling projects in Allston, 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.
