This Brewster basement had traditional fiber glass insulation that was poorly installed and was not controlling the heat and cool air throughout the home properly. This caused the home to have uneven temperatures and a high electric bill. They wanted a solution to make sure air leakage is totally prevented. They decided to give Connecticut Basement Systems a call to help find them a solution.

The experts at Connecticut Basement Systems installed Spray Foam on the ceiling of the basement. Spray Foam was the best option for this home because it effectively fills voids and odd-shaped spaces, meaning that you will always get total coverage. This product will stop air leakage, making it effective at saving the home owners money through their electricity bill. Lastly, Spray Foam will not absorb moisture or lose R-value like fiberglass. 

Now that their basement ceiling is completely Spray Foamed, these happy homeowners enjoy consistent temperatures throughout the home and a lower electric bill!

Basement Finishing & Remodeling in Brewster, NY

Waterproofing your basement prevents outside water from coming in but what if a pipe bursts or the water heater leaks inside the home. A newly finished basement done by your average contractor will mold and rot if there is an internal leak. You'll have to tear out your new basement! We fix this issue.

Our Products Include :
  • Waterproof, washable, insulated walls           
  • Mold-Resistant, No-Sag suspended ceiling
  • Modular carpet, tile & faux wood flooring

  • Energy-efficient, double-paned basement windows
  • Attractive Sunhouse basement window wells
  • French, bifold, louvre & six-paneled steel doors
Unlike the average Brewster contractor we use completely inorganic, waterproof materials. Even if the basement floods your walls and floors will not be damaged by the water. These waterproof products are patented and are built to create an attractive finished basement that lasts a lifetime.

When it rains there is seepage from a basement wall.I'm considering water proofing the inside wall or installing a drain pipe on the outside.
Project Location: Brewster, NY
I have a covered porch attached to my house that did not have proper footings installed prior to building adding it onto the house. Curious as to what the cost would be to install helical piles to correct the issue? Some settling is happening and we'd like to finish the room and make it more of a 3 season type room/sunken living room.
Project Location: Brewster, NY
Believe exterior footing drains on two sides of full basement need to be rehabbed or replaced (if put in when house was constructed in'83). Interior basement drains were installed by original home owner but currently only results in flooding without a permanent sump pump and external pump drain installed - currently not present. Believe it was removed prior to original owner selling us the house in 2006. Interior corner of basement - slab concrete foundations and porch are above - also weeps water during heavy rains and spring thaws.
Project Location: Brewster, NY
Last few storms and thaws I've been getting water in basement. I've been in house last 23 years but problem only started last couple. I would like to have someone come by to give me their recommended fix and an estimate for the work.
