Does old insulation need to be removed before the foam can be installed?

It depends on the area of your home that is to be insulated. The old fiberglass in your walls can stay right where it is, while the old insulation in your attic, crawl space, and rim joist will need to be removed. Learn more.

How long does the installation process take?

Most homes can be insulated in a day or less, but there are cases where it can take two days, like if old insulation is being removed from a large area like the attic. Learn more.

Is foam insulation safe to have in my home?

The quick answer is yes, as both the injection and spray foams we use are safe to have in every area of your home. Learn more.

How does foam insulation work for sound deadening?

Open cell, which is a thicker and softer material, reduces sound waves. This means it will deaden some sound transmissions, but won’t completely soundproof a home. Learn more.

Who is foam insulation a good fit for?

Foam insulation is a good fit for homeowners looking for a permanent fix for issues like uncomfortable rooms, high monthly energy bills, condensation and moisture issues, frozen pipes, and ice dams.

When isn't foam insulation a good fit?

If a homeowner is looking for the cheapest material, an insulation DIY project, or the area to be insulated is very small, then foam insulation may not be a good fit. Learn more.

What makes foam insulation different than fiberglass or cellulose?

Both spray foam and injection foam insulation are the only materials that can create an air seal in your home. This air seal will seal up the building envelope making your home more comfortable and energy-efficient.

What are the best places to insulate in an existing home?

Honestly, the best option is to insulate every area of the home. You don't have to do them all at once, but sealing your home's building envelope will keep those trouble spots from popping up somewhere else.

What types of foam insulation do you offer?

Foam is all we do. We offer injection foam, which we use for the enclosed exterior walls. For the rest of the home, like the attic, crawl space, rim joist, and basement we use open cell spray foam. While we usually recommend open cell for residential projects, there are times that closed cell is the better fit.

What is the install process for existing homes?

On the day of your install, the foreman will go over the project with you. Next up, the crew will do any prep work needed to get the install ball rolling. The foam is then installed in your home and once cleanup is finished, the foreman will do a walkthrough with you to make sure everything has been done to your liking. Learn more.

Are there rebates available for insulating my home with foam?

Yes, there are rebates available. You can check with your energy or gas provider to see what they offer, but your project manager will also have that information available for you. Learn more.

What if the area that needs to be insulated is inaccessible?

In the case when an area is inaccessible, we can either cut into the drywall or in the case of a tight crawl space, we could cut into the floor. Learn more.
