Stop Basement Leaks & Mold - Spray Foam for Damp, Cold Spaces
The basement is, by nature, subject to moisture. Basements are located under the ground level in most of the times, and this means they are surrounded by earth which is typically very wet almost all the time. During the winter when it is cold, the area above tends to freeze, making it a near-perfect victim of condensation and frost accumulation.
If your walls are poorly sealed, the frost, which tends to melt during springtime, will let the water run down the walls and to the floor causing you to think that your basement is leaking.
Basement Spray Insulation That Stops Moisture
Why We Prefer Spray Foam

Basements need insulation that manages both air and moisture. For below-grade spaces, we focus on solutions that control moisture and air movement – so we generally don’t recommend alternative options that can’t do both effectively.
The key to insulating basement walls is using materials that stop moisture and prevent mold, because below-grade spaces require both air and vapor control to avoid condensation. Fiberglass batts with sheet vapor barriers often underperform because they’re air-permeable and difficult to seal, leaving gaps that trap moisture and reduce the effective R-value.
For these reasons, we recommend an air-impermeable solution such as closed-cell spray foam, which forms a continuous moisture and air barrier, conforms to irregular surfaces, and delivers better long-term performance when properly installed.
The Value of Spray Foam Applied in the Basement
This is by far the best insulation material for the basement and damp areas, for a number of key reasons. The first and most plausible one being that it has a very high R-value, meaning it acts as an air and vapor barrier and is virtually impenetrable. Closed cell spray foam, is particularly perfect for locking out the water vapor, which is in many cases trying to move from the damp basement walls to the finished basement floors.
The value of energy efficiency in a commercial building can never be overstated. Once it is applied to the interior concrete, it offers exemplary results. In addition, spray foam combines several functions in one product, which include:

Save Up To 40% Energy with Airtight Spray Foam Insulation
Not only do our spray foam insulation services save you on potentially high energy costs, the liquid sprays also save up on material costs that may have been incurred while seeking alternative methods of insulation.
Compared to the 30 % energy efficiency of other insulation forms, our spray foam insulations can save up to 40% of your commercial building’s energy usage.
Due to its airtight nature, there’s virtually no room for cracks or exposed holes where spray foam is applied. For that reason, the foam product we use at Spray Foam GTA is ranked among the best on the market.
Waterproof Closed-Cell Spray Foam for Mold-Free, Frost-Proof, Structurally Strong Basements
Once it is applied to the interior concrete, it offers exemplary results. In addition, spray foam combines several functions in one product, which include:
- Low thermal conductivity of gases – in basements it typically means closed‑cell spray polyurethane foam or similarly air‑impermeable, high‑R‑value materials.
- Drying potential - which essentially means concrete in a new concrete foundation is able to dissipate harmlessly without the risk of mold growth
- No possibility of frost due to the tight air seals - Tight air seals prevent cold outdoor air from reaching interior surfaces, eliminating the temperature drop that causes frost to form on basement walls and components.
- Basement Moisture Control - since closed cell insulation is waterproof, water will not come into the basement in the event of a leak in the foundation.
- Friendly coverage: pipes, wires, HVAC - Pipes, wires and other useful utilities all around the basement are covered with ease.
Should New Homeowners Consider Basement Insulation?
For people looking to move into a new house, basement insulation is of utmost importance. While sales agents may not necessarily advice for the insulation to close the house deal on cheaper terms, in the long term, you may end up overwhelmed with insulation-associated repairs, or lack of it thereof.
Going that extra mile and adopting spray foam insulation is practically a long term investment when you are moving to a new home.
