We certainly aren’t done yet, but we will keep this company involved as we continue to work forward through some major renovations. We just started with them for essential repairs before embarking on the more ambitious projects. Kaydn has proven himself as very knowledgeable and capable. More to come."

"Brendon replaced my kitchen subfloors and put a new linoleum, full trim all the way around, a bathroom bifold, and even put a special touch to the trim, so I'd think of my late farther who had worked in that same kitchen many moons ago. Brendon had some challenges with old school techniques, but worked long and hard to end with flooring, trim and doorway that was beautiful and I was pleased with the outcome."

"Robert C I live in Brook Farm Edge RD Westbrook Maine crystal recommended Innovative construction. I went over to Crystal’s house and looked at the project that he was doing for her he went above and beyond for her. There was never no signs of any alcohol abuse or drugs on my job. I feel bad for the company because what is she is stating is not true. I seen the job after it was finished and looked amazing. And also said he installed the trim for free for her I was very impressed by his work. I can’t believe Crystal is putting this about him.They did excellent work for me. I would highly recommend them. I was on his home advisor account, looking at his reviews and noticed what she said. This is unbelievable. I did read his comment to address the situation. In crystals review. I just want to clarify that he did great work for us. Thank you."

"They did a good job especially considering how brittle my old siding had become over the years. I’m pleased with their work and the price was right. I plan to hire them to do a couple more small jobs that I’m to old to do myself."

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.
