"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."

"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."

"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!"

"We were looking to have a deck built for our above ground pool and Marco was very knowledgeable about pool decks. His pricing seemed very fair so we hired them to build our deck. The new deck came out great and looks amazing. We love the work they did and would highly recommend 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.
