Reassure the homeowner that you’ll do all you can to make sure the installation goes as smoothly as possible and that the job will stay on schedule. To do that, be sure to:

  • Check the moisture level. Spray Foam should not be applied if substrate moisture levels exceed 18 percent moisture content. In some cases, large dehumidifiers are needed to stay on schedule.
  • Check the temperature. Primarily in colder climates, temperatures can be an issue. For closed cell foam, there are spray foam blends (winter blends) that can work well in temps as low as 20 degrees or lower. Having dry warm air provided on the job site will increase the odds of a successful application on those sub zero days. If temperatures are too cold ,the spray foam will not adhere correct to the substrate.
  • Make sure you have a clean jobsite. Making sure the spray foam application area is clean and safe will decrease the liability of a injury or accident and increase the chance of executing the spray foam install in a timely manner and keeping your job on schedule.
