"Our existing Owens Corning wall panels had been damaged in a basement flood. Although the framework and panels had changed since our initial install some 20 years ago, they custom made new panels that fit perfectly. Additionally, they replaced interior doors and repaired drywall. The work was done on our schedule and done to our satisfaction. Their customer service was great. They came back out to adjust a door that wasn't closing perfectly."

"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."

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"This team is amazing - I cannot underscore that enough! After my family member became disabled due to an accident, we needed accessibility modifications made to our home. AIP completely restructured a fairly small existing bathroom into an ADA-compliant bathroom with roll-in shower stall that is beyond what we had even thought possible. They had knowledge of and experience with specs and features that would be necessary for someone in our family’s situation - many of them details we didn’t even realize we had to consider. AIP were meticulous about sticking to their work schedule as promised and finished the job LITERALLY TO THE HOUR that they promised it would be done. They even left the new bathroom and their workspace sparkling clean and ready for instant use. Perhaps best of all, they demonstrated consistent care and compassion for our family as we made our way through the early weeks of our sudden and sad circumstances. I recommend them over and over again"

FAQs for basement remodeling projects in Winchendon, 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.
