"I recently completed an approximately 800 sq. ft. basement renovation with Owens Corning/Lux Renovations, including a full bath and wet bar, and the experience was excellent from start to finish. The project began earlier than expected, stayed on schedule, and was completed beautifully in five uninterrupted weeks. Our project manager, David Guimaraes, was professional and always accessible by phone or text, and onsite weekly, while onsite supervisor Alvaro was present daily and consistently went above and beyond to ensure our satisfaction—including adjusting a wall so a large piece of furniture would fit perfectly. The materials were high quality, and I appreciated the flexibility to substitute my own fixtures, with changes made seamlessly and without issue. I love my basement!!! If you are interested in doing a basement renovation, I would highly recommend this company. Basement renovations are their business and they are great at it. "

"Justin came over early on a Sunday morning to assess damage to our bathroom drywall. He completed the restoration job over the next few days. He was prompt, clean, and let us know when he would arrive. The job was done beautifully, and I would not hesitate to hire him again! "

"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.

"We are very impressed with XCC and their team. Our property is very challenging and there was now solid ground where the deck was being installed. XCC built us an amazingly beautiful and solid retaining wall. We absolutely love our deck. They even went ahead and added an extra landing for my elderly mother to take a rest on. We will definitely be calling them again when we are ready to update the deck on the main house."

"Bob was amazing throughout the entire project. Was very knowledgeable about everything we requested and helped with the planning process from beginning to end. Gave extremely realistic cost and timeframe. Was extremely professional the entire time and always made sure to clean up and it never felt like we were in the middle of a “construction sight”! We were so happy with his work that we are planning more projects. I would not have any hesitation in recommending Bob for a project. You won’t regret it!!! "

FAQs for basement remodeling projects in Deerfield, 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.
