"Let me first start off by saying Jon and his team at Coastline Construction are top tier. I put an inquiry into Angi's list and Jon showed up the next day, talked to me about specifics and gave me a timeline I could expect, his quote was very reasonable (lower than others as well) and he stayed within budget. My roofing work came out fantastic and I would recommend this crew to anyone looking to have work done on their homes or businesses. Thanks Jon!"

"We had water damage from a burst pipe in our finished basement. It took out part of our ceiling, an entire wall, and parts of other walls. Mark was able to come in and put up the drywall in a fast timeframe compared to other contractors. This included taping and mudding. Mark gave us recommendations for some other concerns we had in our basement regarding exposed electrical panels. He also added an access panel in the ceiling for us that was not part of the original plan. This new addition now allows us to access pipes that we previously were not able to."

"The crew built a 100 ft long section of 6 ft cedar shadow box fencing. They were able to raise the bottom up by one ft for a total height of 7 ft. It is absolutely stunning!"

FAQs for basement remodeling projects in Islesboro, 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.
