We have been in the building trade for 25 years and added specialty weatherization 6 years ago. We are certified contractors for Maine State Housing Authority and Efficiency Maine. We are EPA Certified Lead Safe Renovators and fully insured. BPI Certified.

"Horrible Job! This outfit changed their appointment times at least five times before actually starting the job. They blew cellulose insulation into our east bedroom attic, but had complete disregard for the mess they created. They ran the discharge hose up through an open ceiling hatch with no attempt at sealing the opening. As a result, cellulose debris & dust was EVERYWHERE! It took my wife and me several hours of vacuuming, washing items, shaking out blankets and rugs, and serious dusting to get the spaces back somewhat civilized."

Basement Waterproofing, Crawl Space & Foundation Repair experts since 1991. Free estimates & inspections.

"I had a basement waterproofing project done by TC Hafford in March costing over 19K. It is now July and my basement is full of water, once again,on this rainy day. I have been back and forth with this company for months, and after sending someone in who finally admitted to faulty installation, I am still waiting for them to fix their mistakes. I absolutely would never recommend this company to anyone."

Basement Waterproofing questions, answered by experts

Some basement waterproofing methods can actually cause your water or moisture problems to get worse, which is why it’s so important to call in a professional who knows how to solve your underlying issue and use the appropriate waterproofing methods. An example of this would be applying latex waterproofing paint to the insides of your basement walls without fixing the water issue outside. Doing so can trap moisture in the basement walls, which can promote mold growth, peeling paint, and even damaged concrete. However, when done by a professional, the only downside to basement waterproofing is the up-front cost.

Flooded basement cleanup can take anywhere from a few days to several weeks, depending on the extent of water damage, the type of water involved, and the need for repairs or mold remediation. Severe cases with structural damage or extensive mold may require longer timelines. Quick action and professional help can speed up the process and reduce overall damage.

You should plan on waiting at least a year and ideally two to three years after construction before finishing your basement. This will give the foundation time to settle in response to the weight of your home and the expansion of the surrounding soil. You can then repair your foundation and seal any cracks as needed before finishing it to reduce your risk of future leaks or other issues.

The best way to ensure the ground next to your home’s foundation drains properly is to divert water away from it as much as possible. While a flood wall can stop water from entering the house, gutters and spouts can help direct rainwater and melting snow away from the foundation. Keep your gutters as clear as possible from dead leaves and other yard debris so they can effectively divert water from your house. Add extenders to the spouts so the water runs out and away from your home, not into the surrounding soil.

Statistics show that 98% of basements will experience some form of water damage over time. However, that doesn’t mean all basements will experience severe flooding. The best way to prevent a water-damaged basement is to keep up with home maintenance and have proper drainage installed outside your home to direct water away from the foundation. You can also consider building a flood wall around the house if you live in a flood-prone area.
