"Our existing Owens Corning wall panels had been damaged in a basement flood. Although the framework and panels had changed since our initial install some 20 years ago, they custom made new panels that fit perfectly. Additionally, they replaced interior doors and repaired drywall. The work was done on our schedule and done to our satisfaction. Their customer service was great. They came back out to adjust a door that wasn't closing perfectly."

"This was our second home improvement project with Kirk (ASK), and once again, both Kirk and Paul were fantastic to work with. Communication was clear and consistent throughout the entire process, and they were always generous with their suggestions, guidance, and support along the way! This project was larger than our first and required an even higher level of attention to detail - and they truly delivered. Kirk took the time to make sure everything was done right, and it really shows in the final result. We couldn’t be happier and wouldn’t hesitate to recommend Kirk and Paul to anyone looking for skilled, thoughtful, and reliable contractors!"

"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."

"????? 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 "

"Very pleased with the work done by Jonathan Fiske. Jonathan delivered the door which we painted ourselves. When it was ready, Jonathan came out within a few days and installed the frame, door and moldings in one day. He also replaced the alarm sensor, made sure proper flashing was installed and took the old door away. He answered all questions that we had. It was a pleasure working with him and would recommend him to others."

"Northeast Remediation performed deleading on my home, involving replacement of windows and the garage door. The house passed re-inspection for full compliance as soon as they were finished. The only issue was that they had problems getting one of their suppliers to provide a custom sized replacement garage door in a timely manner. This delayed fully completing the job by about a month while they found a different supplier. However, they were generally very responsive with communication and the work quality was good so I would not hesitate to use them again."

FAQs for basement remodeling projects in Madison, 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.
