"My project was small compared to many other projects out there. And yet Josh and Straight Line Constitution were happy to take my business and made it a priority. There was some urgency to getting it done and they sent the right number of people to meet the deadline. And when unforeseeable complications arose they worked with me in order to find a solution that would achieve the goal of the project without extreme cost overrun. There are many contractors out there who will give you a wide range of quotes. If you want to go cheap then find someone who will do a half ass job for little money. But if you want it done right and you want it to last call Straight Line Constitution. The rates are reasonable the quality is top-notch and they're very friendly people to work with."

"Would not recommend. Blew me off for over a month and a half after a verbal agreement for a job and then changed his price and told me he would only do it for double what a competitorâ s quote was. Dishonest and unprofessional."

"????? If I could give zero stars, I would Hiring this contractor was a nightmare from start to finish. The bathroom they delivered is so poorly done that I feel like I need to redo it entirely. They rely on subpar subcontractors with no professionalism or craftsmanship. ? Overpromise and underdeliver: I had to stay on top of every detail myself, doing the job the contractor was hired to manage. ? Unreliable: Never kept appointments or confirmed schedules. The only time they showed up on time was to collect payment. ? Unsafe practices: At one point, a subcontractor was cutting concrete inside the bathroom with a gas?powered tool, filling my entire home with smoke. I had to intervene to stop it and argue just to get basic protections like tarps in place. ? Poor management: Subcontractors openly complained about not being paid, and I even had to send one home myself because of unacceptable behavior. ? End result: Substandard work that does not reflect the money spent. Save yourself "

"I had serious water problems in my basement, and a crumbling foundation. The concrete block foundation had lost a lot of its grout and was bulging dangerously. Wright straightened the wall, installed French drains on two sides of the house, insulated the interior walls and ceiling of the basement, and installed a thick plastic vapor barrier on the floor. They poured about four inches of cement on the floor and installed a heater that will keep the temperature above freezing in the basement. This makes it easier to turn on the water and to heat the upstairs if I come up in the winter. The cost was about $40,000. I was very pleased with Wright's workmanship, responsiveness and the quality of their staff. I would recommend Wright without hesitation to anyone with an engineering problem."

FAQs for basement remodeling projects in West-lebanon, 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.
