Building Finished Basements that Last

1. You want to have a comfortable, beautiful finished basement, BUT you want it to last!

2. Most contracting companies use standard “above-grade” materials which is a recipe for disaster. These materials end up with mold and mildew and you have to tear out the whole basement and start over.

3. Total Basement Finishing contractors eliminate these problems by only using completely waterproof, inorganic & mold-resistant materials that are designed specifically for basements. You will have the basement you've wanted and it will last long as your house.

  • Full Basement Bathrooms
  • Variable, Energy-efficient Basement Lighting
  • French, Bifold & six-paneled steel Doors

A professionally remodeled basement can do all of this and more! Transforming a musty basement into a safe and usable living space will drastically increase the resale value of your home. A finished basement with eco-friendly additions, such as our EverLast Basement Windows and Energy Star SaniDry dehumidifier, can decrease your home's energy usage and lower your monthly electric bill!

    Our basement is small and tricky and needed many creative workarounds. From our interactions with our project manager Ken and his crew to the final basement outcome, we had an outstanding customer experience and are thrilled with the appearance and functionality of our new space!

    Was pretty painless - the two rooms they did came out pretty fantastic and they were able to work with and around existing duct work and plumbing in such a way that it looks really good and not out of place!

    Customer Review

    By Sarah S.
    Fremont, NH

    We had over 700sqft of our basement finished with TBF. They were the first and only quote we received. The second company we called for a quote basically didn’t want to come out after we had told then we met with TBF. The lady was defensive & short when we asked questions about their system - big turn off!Our Sales rep, Jim, was very thorough. He worked with our budget to get us what we were looking for.Our project manager, Tim, was very responsive & addressed all of our concerns, small or big! Contractors were friendly & professional. Workmanship is beautiful, a lot of compliments from family & friends. The bulk of project was completed within 4 weeks & entire project completed within estimated time frame of 8 weeks.The only thing I wish we had done differently was to make the door to the unfinished area slightly larger. I believe is standard size but it is hard to fit some of the bigger objects/furniture through. This is something we had not thought of until we began moving stuff back in (especially since there is a support beam just beyond it). But given all the “stuff” going on in the ceiling (pipes, HVAC etc) not sure a bigger door would have been possible. But just something you may want to keep in mind...This was not a cheap project - but as we say,“Good work ain’t cheap & cheap work ain’t good!” I feel good knowing there won’t be any mold growing on our walls etc. We will definitely consider them for future renovations. I think what I liked about them the most was that they never seemed agitated with our requests/concerns & made sure we were happy with our new space. Hope this is helpful!
