"Because we were going away for an extended time, and insulation work by others had to be completed first, we had to schedule drywall workday NH Projects under a rather tight time frame. Despite uncooperative weather (lots of rain slowing the drying time), they managed to get everything done as needed, working around other scheduled work they had. They were prompt, professional, and a pleasure to interact with, in addition to doing excellent work."

"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."

"They are very good at what they do. We re-hired them after they did a job for us over last summer. There were differences on a this second job. If you use this company, I recommend: 1. Insist on a thorough, detailed contract that specifies ALL the details. Several things were forgotten, and later treated as ;added and as scope change. Could have been avoided with cleaner communication. 2. Specify in writing whether or not sub-contractors will be used for the job. During this second job, we had a couple of sub-contractors that were really, really bad. a. If sub-contractors are used, recommend specifying that a crew chief from Ideal be on site at ALL times. If needed, they should provide translation services. Our place was trashed when they left the site; sheet rock dust everywhere, floors to scrape, a hole in the wall to fix, lots of hard work ahead. They knocked off $2K. I would not do this amount for $2K. Bottom line, do not feel it was an fair solution. Learned a lesson."

"Adam, the owner of Magic Frog Carpentry & Woodworks is great to work with. He is responsive via text and phone conversations. He has a lot of skilled people he works with and does a lot of the work as well. When any hiccup comes up he is quick to get it resolved. This past fall I hired him to do a partial remodel of my kitchen (new countertop, new backsplash, new flooring and painting. I was happy with the work and decided to hire Adam again for a tub to shower conversion. I am really happy with the results of both projects. I plan on reaching out to Adam for the next home project.

"Eli came out and re graded a whole residential yard for me along with taking out and reinstalling a rock bed on the side of my house. He did a great job and I highly recommend Precision Works for anything excavating related! Eli is a super nice guy, very professional, and is very fair with his pricing! He was very honest with the whole job from start to finish!! If you don't hire this company, you will be letting yourself down!"

"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."

FAQs for basement remodeling projects in Gilmanton, 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.
