"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 was very easy to work with. Background: We had a french drain and drainage installed due to flooding. Prior to that work, the basement was already finished, but this work required us to need a new floor and baseboards. We had tile down and wanted to put an laminate down. After talking with Pedro prior to any work being done (during the consult), it was decided to see if it was better to level the floor to the remaining tile or jack hammering all the remaining tile up. We had an idea of the product we wanted, and he was able to recommend a different version of the product that was better that we were not aware existed. Our basement baseboards were tricky. We were told to use PVC wood, but Pedro recommended against it since it was an enclosed space that we would be using and that is known to release toxins. Once work started: Pedro and the men were such hard workers. The time they arrived in the morning could vary depending on if they went to Home Depot first. The time they left depended on how much they wanted to complete before they left. Every night they cleaned up (and this was a space we weren't using at all.) Each day I got an update on the status. While laying the floor, Pedro had to work around drains in the floor. With the french drain, we had this plastic wall trim to have water drain into from the wall. It was very ugly and couldn't be kept as is since part of the tile behind it was destroyed. Pedro worked with me to create a nice looking baseboard with a gap to allow for the water to drain into the french drain. We also decided last minute to make a small cellar room (with stone foundation walls) into a real room with insulation and walls! They were able to get that done as well and it looks amazing. (I didn't rate price, because I didn't comparison shop. I had originally contacted Pedro and got a quote. Then ended up contacting him to find out when he could do it and was told the following week. I wanted the basement job finished before I went back to work so didn't bother to comparison shop.)"

"We were very pleased with Kinsella Built's craftsmanship and work ethic. We had an extensive job that required them to replace a rotted post that was structurally required to hold up the back porch. We were pleased with them so much that we had them come back for a basement remodel job. They maintained a great sense of humor while on the job. Best part is that they completely stand behind their work. : ) We are looking forward to having them come back soon!"

"Khaled and his team were outstanding. The attention to detail, the quality of the workmanship and Khaled's attention to my questions and concerns during the project were all top notch. As with any project this size (mine was an entire basement remodel approximately 800sqft that included some minor demo), there were some complications, but the measure of any situation is how the stakeholders address it and there too, Khaled proved that he is made of superior customer service mettle. He got in front of the problems we were facing and addressed them methodically and kept me apprised as needed. He has a marvelous crew and they are all quite fun and knowledgeable. I absolutely love my finished basement. The walls and the painting job alone makes it worthwhile, and that was just the finish work! Fantastic! Strongly recommend Abalia for all your construction and remodeling needs."

FAQs for basement remodeling projects in Charlestown, 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.
