Jack delivered the work on time and the work is of high quality. As most projects go we had some small unexpected issues, but Jack communicated well and was able to navigate them and still the project on time. I would highly recommend him and his team for your home renovation projects!"

"We had a great experience working with Wes from Boynton Builders LLC! We had a pretty extensive basement remodel / conversion to living space project that we needed help on, and we are extremely happy all aspects of this project using Boynton Builders LLC. Wes responded quickly to a voice message I left, was able to quickly schedule a time to visit to discuss our intended Scope of Work (which also involved another project re-enforcing a carrying beam and support post in our detached garage) after which he quickly provided detailed quote that fortunately fell with our budget. We agreed to move forward, and Wes went to the Town Office for us and took care of the Building Permit and were able to start our project within a couple of weeks and the work proceeded at a good clip with every stage discussed being performed in the order identified from the onset. As the project progressed, we added an additional phase to the scope of work (Install Flooring and a new double door) and he quickly estimated the additional cost got the next phase into his schedule about a week after the completion of the first / original project. Throughout the whole project Wes was pleasant, professional, motivated and productive and open to any requests for change as the space began to be completed and new ideas came into play as we were better able to visualize the final result. Wes completed all of the work on time and within the budget/ and additional scope estimates. We already have the next project planned and will be using Boynton Builders LLC again. Any friends that have seen the completed project state that it is "an incredible transformation" and we are proud to welcome friends into a space that was once an embarrassment. I would also like to mention that I originally reached out and left the same voicemail (one right after the other) for three different contractors and Wes was the only callback received, and that was within a couple hours."

"We met Dan months before the project was scheduled to start and he knew our deadline was 7/9 when our first weekly vacation renter was due to arrive. Our main issues were: He was a week late starting Didn't show up on several days (had to take his son to get his COVID shot, several days it was too hot, heavy traffic, etc) Ignored my detailed instructions/drawings and we lost time because he plumed a double vanity for only 1 sink, told us we could buy any standard shower door from Lowe's only to learn AFTER the shower had been framed that it required a custom built door, forgot to tile the accent color stripe in the shower, miscalculated the amount of shower tile needed requiring me to drive 3 hours RT to purchase extra tile and deliver it to him. Skim coat on the ceiling was done poorly, the door to the bathroom didn't open all the way so we had to hire someone after Dan left to shave it down for us. He was supposed to finish by July 9th and didn't finish until Sept 9th!!!! had to give renters $3000 off because they had no toilet or shower. I split the difference with him and took $1500 off his bill and he was not happy. I should have taken the entire amount off. He might be OK for smaller jobs, but he is not focused enough and doesn't work a full day (usually 8 AM -1 PM) or even a full week. If he takes work outside of NH, he should have his plumbing/electrical license so he doesn't have to rely on outside contractors. We suffered because he didn't hold ME licenses and wasn't well connected w/ local contractors in ME."

FAQs for basement remodeling projects in Cornish, 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.
