Where to Use DIY Spray Foam Insulation Kits

Spray foam insulation kits can be used in any area of the home that is open.

These areas include the attic, open wall cavities, crawl space, and rim joist. Also around the windows, doors, and to patch existing insulation.

What you will want to keep in mind is the size of the area to be insulated, along with the proper thickness in inches of foam needed. The prices above are for one kit only, so insulating larger areas or multiple spaces it could get costly.

Do-It-Yourself Versus Hiring a Contractor

The prices listed above cover just the spray foam kits if you decide to do the job yourself. If the project seems too big for your abilities, you may decide to hire a contractor instead.

To hire a contractor would be more expensive, but that extra cost comes with peace of mind that the job will be done correctly.  It’s also important to note that you will have to buy not only enough product to finish the job, but also enough to cover any wasted product lost while learning how to use it.

Also keep in mind that insulation contractors usually have a minimum job cost. In some cases spray foam kits work really well for small projects, so it wouldn’t make sense to hire a contractor. However, when you crunch the numbers for a job even as small as a rim joist and factor in your time and wasted material, it will probably be cheaper to hire a contractor. This is especially true if they offer a warranty.

Hiring an experienced contractor is advised to save yourself the headache of a mishap, wasted materials, and to avoid damage to your home. A good contractor doesn’t use foam insulation kits. This is because they’re difficult to use and are often times inferior to the high-pressure products used by professionals.
