"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."

"Excellent. We added a bathroom and a bedroom, took down paneling and completely redid the family room. These guys did all the electrical work, plumbing work, flooring, painting and everything else. Amazing communication, stayed on budget, worked very well with us and the work was done quickly and exactly as described. Any issues were immediately dealt with. Any questions were immediately answered. Would absolutely work with these guys again and would recommend them!"

"Timber and Megan are consummate professionals who are timely, hard working and detail oriented. I was very fortunate to have them realize a project that was centered around creating an in-law apartment in an existing space in my home for my father. They worked with me every step of the way which resulted in a collaborative design with a nautical theme. The end result is stunning and everyone who sees it wants to live in it! Thank you Timber and Megan for making my vision a reality."

"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."

"I recently had Core Remodeling help remodel a kitchen and bathroom and the experience exceeded our expectations. Their team demonstrated professionalism, expertise, and a commitment to customer satisfaction. The kitchen remodel included new flooring, countertops, and appliances, and I couldn't be happier with the results. The craftsmanship is great. The end result has transformed the space, making it both functional and aesthetically pleasing. Similarly, the bathroom remodel was executed very well. The attention to detail in every aspect of the design and installation is evident, and the end result is great. One of the standout aspects of working with Core Remodeling Company was their project management. Communication was excellent throughout, and any questions or concerns I had were addressed promptly. Overall, I highly recommend Core Remodeling to anyone considering a home renovation project. Their dedication to customer satisfaction, attention to detail, and project management expertise make them a top choice."

"Competent and professional, courteous and careful (Covid protocols), cleaned up and tested correctly functioning before leaving. Able to be flexible on the scope of the work prior, since we had not finalized details, but came properly equipped and understood the electrical needs. My only critique is that the pricing policy was not explained well - apparently just to show up is priced on (2) workers - so 175 for the mgr, 95 for the helper, then the hourly 95 is separate. Anyways, good job, well done."

"Unfortunately I give BBB a 1 star rating. The project began October of 2021 with demolition, upon completion of each phase I sent an email to Better Built Basement management thanking them for their work effort and identifying items that either required further explanation and/or resolution. As the project went on, I became increasingly frustrated with their lack of communication, lack of accountability, lack of caring, and lack of skill. The straw that broke my back was when Jim (an owner) called me a f’ing c’sucker. Randy, (an owner) sent me the following email: No one has time to read your 3-page condensing e-mails. You have done nothing but complaint. It's obnoxious and draining to everyone you come in contact with. There isn't one person who cant wait to have you out of our lives. I terminated Better Built Basements on June 7th, 2022, here are some of the details of my experience: - The demo crew was excellent in and out in a day and did a great job cleaning up - The electricians were very consultative in their approach to the project, providing input on lighting and outlet placements. - Framing was mediocre. Despite using laser equipment, one wall was wavy and the ceiling grid has a large gap. Pictures attached. - New steel stud framing and pre-hung doors should be dead on straight as an arrow instead, two of the doors has an aesthetically noticeable skew. - The replacement to an existing door resulted in using the wrong hinge set for the existing mortices, inclusive of color – all the other hardware is brass they used chrome. Picture attached. - 3 of the four doors were either chipped or cracked. BBB was notified before the ‘final’ paint job, but they failed to address the issue. - I returned home the day they applied joint compound to find glops of joint compound on the floor, which I tracked around my house, and glops on wood work on a floor where no work was occurring. Pictures attached - Following the flooring installation, they left garbage in my basement for 2.5 weeks, then did not take it when they came back – in frustration I disposed of it myself. - Many of joints on the ¼ round trim molding were caulked excessively to cover up sloppy miters. - Cracked switchhplate was not replaced. Picture attached. - Sub-contractors have sub-contractors, who seem to be able to sub contract – direct employees of BBB other than the demo and electrical were rare. BBB demands using a lock box, Many people have the combination, providing little sense of security over access to the home. Overall, BBB does a bad job communicating, managing expectations and fails to deliver on their stated objectives at best they are contractors not craftsman."

FAQs for basement remodeling projects in Thompson, CT

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.
