"Jesse and his veteran crew of subs built a large log home for us. These are tricky homes to build. Any unexpected events were handled professionally. We plan to hire him again to renovate the unfinished basement."

"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."

"I recently had my shingle roof replaced and I?m very happy with the results. The team was professional, punctual, and completed the job efficiently. The quality of the work is excellent, and the new roof looks great. They kept the work area clean and communicated well throughout the process. I would definitely recommend them to anyone needing a roof replacement."

"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."

"I wrote the C review. 3 years later, the windows leak every year and there is a leak in another room under the roofing that Sean "fixed." I have just learned that there are holes (where he put his scaffolding) above the leaking area. The windows were new and the only leaks are below the holes. I have spoken to other roofers who say it was a very poor job and should be redone."

FAQs for basement remodeling projects in Plymouth, 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.
