The Spray Team Part I

“I’ve never seen anything like this”, says Jay Sigurdson, above, one of the The “A” Team – aka the Spray Team – who is squatting in my living room with his insulation spray gun. (Oh, I’ve heard that before about this drafty old house built like Frankenstein from spare parts over the decades.)

The worker from Jerry’s Insulating is referring to the space under our front bay window (shown above) – about 10 feet long and a couple of feet deep – that he’s discovered is completely empty and is taking in tons of the “pour foam. “Just wait until you feel how much warmer you’ll be in here,” he adds. (Music to my ears.)

I hear the hiss of their spray guns as they pour the Icynene foam (only used for plaster walls) into the toonie-sized holes they drilled in the exterior walls of he living room (2 walls); kitchen (1 wall, including drilling through back of cabinets); bathroom (1 wall); kids’ bedrooms (2 walls each).

“This job would have taken us at least a couple of days when the company started” almost a decade ago, says John Allan, the second insulator. Instead, today it’s taken only 3 hours total – and that’s for the main floor AND basement insulation work!

  • Hi Heather – as the owners of a drafty old house we’ve thought about doing this but were told it would likely pop the plaster off our walls as the foam expanded. May give Jerry’s a call for another opinion. Thanks for the info.

  • Our old plaster walls are holding up just fine! Thanks for reading; stay tuned!

  • Have an interwar house that needs insulation… but we are debating on whether we can live with the plaster or go ahead and switch to drywall. What happens with the foam if you later decide to go with drywall?

  • That is a very good question; my guess is that there should be no problem since it is the pressure of blowing in the foam is the issue – plaster is strong enough to handle that pressure without coming apart.

    But once the foam has dries, covering it up with drywall should not have any effect.

    Best to ask an insulation professional though, like the dudes I used.
