Basement Spray Foam Insulation In Kitchener, Ontario

Basement Spray Foam Insulation Beats Batts On Concrete

Basement walls draw moisture from the soil in every season. When a batt is pressed to that wall with plastic over it, the damp gets trapped in between. Plenty of renovations open the wall to find soggy batts and black spots behind drywall that is only a few years old.

Basement spray foam insulation bonds straight to the concrete. Warm room air can no longer touch the cold wall, so there is no surface for condensation.

Basement Spray Foam Insulation Meets The Newer Code

The 2024 Ontario Building Code set R-20 as the basement wall target for new houses. Closed cell foam reaches that in roughly three inches, which saves floor space compared with a deep framed wall full of batts. In a small basement, every inch you keep is useful.

For an existing house, that figure is a helpful benchmark rather than a requirement. The quote lays out the options and the cost of each.

Older Foundations Get A Close Look First

Kitchener basements range from stone and block to poured concrete, and many have been patched over the years. Homes near the Grand River around Bridgeport can see more ground moisture than homes on higher land. We check each wall for active leaks, cracks and loose parging before recommending basement spray foam insulation.

Water coming through a wall has to be fixed first. Foam keeps damp air out, but it is not a fix for running water.

Basement Spray Foam Insulation In Finished Rooms

Any foam left inside a lived-in room needs drywall or an approved coating over it. In a basement you plan to finish, we spray the walls and the rim joists, and then your contractor frames and boards over the foam.

In an open basement or a utility room, we can talk about coatings that leave the basement spray foam insulation exposed.

Basement Spray Foam Insulation Pricing

Basement walls usually price out at $3 to $5.50 per foot of wall area. Most jobs add the rim joists at the same time, since the rig is already set up.
