Foam Insulation Video

When using the spray foam, sometimes one doesn't use up the entire can during that time.

How to clean the tube to be able to use for another day/application is a topic that I would like to see addressed.

Merci/Thanx

Dear Tim;
I apologise for not commenting on your website and hints before this. Procrastination is my surname, lol. As a small business owner I respect your decision to admit a mistake and move forward. I try to run my business, and my life around this concept mixed with honesty. This has cost me several missed opportunities in the past, and may in the future, but I can sleep at night knowing that I would do it again. But I digress. You have inspired me to work on a website of my own, So kudo's and keep up the great work.
Respectfully your's

Tim,
I have a few places in my house that I could calk to reduce air leaks, but I have some concerns. I am worried about getting the house too tight. The house is 14 years old and located in lower MI. I'm concerned that by getting the house too tight, I will have trouble bringing down the RH and that I may start having condensation/mold issues. How can a person know if the house is too tight such that a heat recovery ventilator is needed? Thanks.
