What Our Clients Say

★★★★★

"They photographed rodent damage in the old insulation that we had no idea about, and priced the exclusion work separately so we could decide."

Harriet N.
Harriet N.Verified customer · July 2026
★★★★★

"Two other companies quoted to blow more insulation on top of what was there. These were the only ones who said the existing material had to come out first, and explained why."

Clifford E.

★★★★★

"Crawl space encapsulation done properly. Photographs of the vapour barrier at every seam, and the damp smell in the hallway is gone."

★★★★★

"The winter gas bill dropped by about a third. They had estimated a quarter, so they under-promised."

Local Service Coverage
Part of Topside

We Are the Canyon Lake Team for Topside.

Envelope was founded in 2016 by a blower-door technician who kept being sent to top up insulation in attics that were leaking air through unsealed top plates and can lights. It refuses to blow insulation over an unsealed attic floor, and it publishes the before-and-after blower-door number on every job so the customer can see what they bought.

Same training, same parts, same pricing practice, and the same 365-Day Done Right Promise - delivered by people who live here.

Materials we install

Materials That Hold the Line for Decades

Insulation is only as good as the material and the prep underneath it. Here is what we put into an attic, a crawl space or a wall, and what the cheap bid puts in instead.

Blown-In Insulation

Loose-fill is most of what goes into an attic. The material and the depth it is blown to decide whether the attic holds R-38 in ten years or has settled to half of it.

What we install
Blown-In Insulation we install

We blow dense, borate-treated cellulose or premium fiberglass to the full code depth with a depth marker in every bay, over an air-sealed floor. Cellulose settles less than 15% and the borate keeps insects and mold out.

What the cheap bid installs
Budget blown-in insulation

A cheap bid blows the thinnest bag count that reads "insulated" from the hatch, over a floor nobody sealed. It settles a third within a few winters, and the gaps around every can light and top plate keep leaking conditioned air.
