"I was so happy with my previous bathroom remodel from Extreme Makeover I hired John again to do another Project on the upstairs bath. Again, the results were better than I anticipated. John Leahy, owner and his associate John produced a beautiful and updated look. The craftsmanship was impeccable and they were always on time and finished the project earlier than promised. John is very courteous and approachable and is easy to relate to. I know you will be very pleased with Extreme Makeover for your next home project."

"We are so happy that we hired Benchmark to remodel our kitchen! Lee and Ian were professional and knowledgeable, from beginning to end. We were very impressed with their attention to detail. They made our 1980's dingy, dark kitchen look amazing with beautiful white cabinets and granite countertops. We love it! I highly recommend Benchmark and will recommend them to my family and friends. Thank you, Lee and Ian! Sallie and Don M."

"We have been wanting to finish our basement for a very long time now but the prices we were given were too high! A friend of ours referred DCL to us and we thought we would give them a shot. The price was right so we started shortly after. They took care of all the paperwork and permits needed! Bob was there for the whole process discussing with us every step of the remodel! Very knowledgable and very well trained team! Our basement looks incredible and we enjoy spending time there! I would recommend DCL to anyone!!"

"We hired Adam to convert our single-car garage into a bonus room (framing, drywall, electrical, flooring, moved a gas line, rerouted the hose spigot, and replaced the garage door with a slider). The quality is fantastic. I’d recommend him to anyone. What really stood out: Adam cared about the details. I had a rough vision, but when we hit decisions I hadn’t thought through, he’d flag it and, if I didn’t have a strong preference, steer me toward the right choice. He had a real vision for how it should look, not just doing the bare minimum or blindly following directions. The other thing was how clean he and any of his crew kept their workspace. This didn't actually matter since they were in a garage we weren't using, but every day it was immaculate, and all the material scraps were removed. Hire Adam because he delivers excellent workmanship, sweats the details, and helps you make smart decisions along the way. Plus, he runs a clean, organized job site."

FAQs for basement remodeling projects in Newton-Junction, NH

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.
