"Our experience with New Leaf Construction in December led us back to hiring them again for a few additional projects we wanted completed outside this spring. The remodel of our firm over the winter was very successful and it was a pleasure to work with their crew. Their professionalism showed throughout the entirety of the project, from the quality of their work, sensitivity to our timeline, accommodating the needs of our business with as little interruption as possible, cleanliness of their work area, attention to detail, and staying on budget. I highly recommend New Leaf Construction."

"Completely satisfied throughout the process of choosing a contractor and having them replace old shingles.  Brian returned my call promptly, met me when he said he would, started and finished the job on time, while keeping me updated daily on the progress, and did quality work. <br />"

"<p>Very Professional Company. Entire job went very well. Job took only 6 working days (during 1 1/2 week) to complete. I would rate the shingle work an A, but I had a few issues with some of the drip edges but they were immediately addressed to my satisfaction. I paid a premium price for the work, according to past bids, but Pearl has a great reputation,  I was surprised they needed to be called back, but they quickly resolved my concerns, not leaving until I approved. I am looking forward to years of life from my new roof!</p> <br />"

FAQs for basement remodeling projects in Sullivan, 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.
