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

  • Basement Staircases
  • Energy-efficient, Double-paned Windows
  • Carpet, Tile & Faux Wood Flooring

We use only high-quality materials when remodeling basements in New Hampshire.

Simply put: we take care of our customers and guarantee that they receive the best service, materials, and craftsmanship around!

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!

    When these folks say "once a customer, always a customer" meaning they will follow up with anything you need, really no matter how small, they mean it! I have experienced this personally as they have made every effort to keep connected with me long after our job was technically "finished."

    Having workmen in your house is inherently disruptive. And yet we kind of missed Chuck and Ron after the project completed. That is a testament to the pleasant nature of their presence.

    TBF did a fantastic job finishing our basement and we couldn't be happier with the outcome. Work was high quality, done professionally and on time. It was a very positive experience with Ken managing the project (outstanding project manager) and Lucas and team doing the bulk of the work (high quality work). We were particularly pleased that Ken and team were genuinely interested in a making sure that work was highly satisfactory to us. Great team and a great company! Highly recommended.

    Working with total basement finishing /Black dog was a hassle-free experience. They were very understanding met all my needs they went above and beyond I could not be any more happy and thrilled with the end results. I would absolutely use them and recommend them again and again. Everyone was just really great to work with they didn't push things on you and that in itself is worth a lot to me.

    TBF was fantastic right from the start providing step by step guidance on the possibilities and expenses for my basement construction. It certainly helped in our decision process and peace of mind. Once the project started, the design work completion, arranging the town inspectors for initial surveys, electrician work and finally the heavylifting work for the floors, ceiling, panels etc was done professionally, with high quality, on time and was excellently project-managed right till the end to final inspections and sign off. We couldn’t be happier and would highly recommend TBF to anyone wishing to get your dream basement. Yes, they are slightly expensive than regular individual contractors but the range of services, quality and professionalism is totally worth it.

    I highly recommend them. They did a great job with our basement and were very responsive to any issues that came up during the process. Even when there was a discrepancy between what was done and what I remembered being agreed to at the beginning of the project (but not in the contract) they were happy to redo it the way that I wanted and at no extra cost.

Project Location: Bow, NH 03304

Comment: We just bought a house that was built in the early 70's. The basement is finished but I want to get rid of the paneling and carpet and re-insulate and put in a proper vapor barrier and flooring. I am going to be apportioning a section of the area to be a wood shop which will also need subfloor and flooring. The main area is approximately 40' x 24' with stair and connecting hallway. there are 3 rooms along the hall. My main concern is finishing the shop area as I need to vacate the rental space my shop currently occupies. The shop area needs minimal functional "finish level".
