"Don replaced two exterior doors for me. These doors were almost 30 years old and presented some challenges. Don did a great job with the installation, repairing unforeseen issues as needed, reassembled interior molding and all with great attention to detail. I would not hesitate to have him back."

"Dean has been an amazing help to me and my husband. We have used him twice now for two pretty big issues. One was a tree through our roof into our bedroom. He did an amazing job repairing the roof and redoing the bedroom. It was a super stressful time that he made easier and the work was amazing. We reached out a second time when our tile shower was leaking and needed to be replaced. Again he did an amazing job completely redoing our shower and it turned out beautiful. He makes these stressful times easier as he is very understanding and easy to talk too. I highly recommend Dean and you will be very happy with the results."

"Brendan did a great job on assembling four pieces wood furniture. He had to construct a wood part that was missing from the materials. It turned out to be rather complex work and we appreciated his attention to detail. Hope we can work with him again!"

"Greg & his crew were very professional. Greg communicated exactly what the cost and date of completion would be. He updated us on a regular basis on how the project was moving along and finished ahead of schedule. I would highly recommend Innovation construction for your home project. We look forward to using Greg again on our next renovation. Tom & Denise Rooney - Bath, ME"

FAQs for basement remodeling projects in Lewiston, ME

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.
