Customers say: True professional

"Ultimately everything went exactly as agreed. I am very happy with the work and the material we selected. The basement was mostly finished prior to the project, but we have noticed a huge improvement in the areas that were added and the all new flooring. The added electric was done professionally and it showed. The communication was fantastic with the project manager, who was responsive and courteous. I would recommend this addition or renovation to anyone who’s considering it. The value it adds to a home and to your lifestyle is worth every penny."

"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."

"Tom and his crew did a great job. The work was completed in a timely manner. The final result was a really solid and good looking porch. I have other projects for Titan Builders, which I have elected to hire for those projects as well."

"The company (Black Dog) was hired to expand the bathroom and part of the basement renovation. The project started in October 2020 and it is still going through May 2021 with an unclear restart date after 2 no shows. It was promised to finish by Christmas. The company used 2 different colors of grout in the same room. They are planning to come back and redo it, waiting for 2 months now. They do not want to spend time on fixes. Leakage around the shower was noted, they promised to contact the subcontractor, but I have not heard from them yet. There are minor things missing, would pay attention to their contract as they may not do things like shelves installation as originally discussed. They seemed professional on initial evaluation and at the beginning, but now I am regretting that I hired them."

FAQs for basement remodeling projects in Gardner, 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.
