"All Seasons Insulation gave me the most reasonable quote, out of the three companies that came out to bid. We had them blow in insulation in the attic that took my existing insulation from R-10 to an R-38, as well we had all of the exterior walls insulated. They showed up on time. Very professional. The job turned out great! They did a great job cleaning up after the project was done. They matched my stucco texture perfectly with their patches. My house feels substantially warmer and quieter. Highly recommend them!"

Insulation questions, answered by experts

Mold can grow on garage ceiling insulation, which is why it’s important to install a vapor barrier behind the insulation and keep the space cooled and heated as you would your living area. Doing so will more or less eliminate the risk of mold growing on your garage ceiling insulation. You can also install a self-draining dehumidifier to help remove moisture, or opt for a foam board insulation or spray foam insulation that won’t harbor moisture and mold.

Yes, insulating your cold water pipes is a great way to prevent condensation. When warm, humid air meets cold pipes, condensation forms, which can drip and cause moisture issues in your home. Pipe insulation acts as a barrier between the warm air and the cold pipes, keeping condensation at bay and helping you avoid potential problems like mold or structural damage.

The lifespan of cellulose insulation is 20 to 30 years, on average. That said, it’s important to start checking your insulation after year 10 to check for degradation, mold, mildew, and other potential problems. Every 10 years, you should also confirm your home’s insulation is in line with updated local building codes.

Yes, insulating hot water pipes helps your system run more efficiently. This is especially true in basements in colder climates, where cold air likes to settle in. There are a few ways to insulate water pipes (foam is common) to keep hot water hot, reducing the need for your water heater to constantly heat the water in the tank or your circulator to kick on more than necessary.

Because of the moisture concern, open-cell foam requires a vapor barrier. The barrier protects against high humidity and moisture exposure in rooms such as basements, bathrooms, or exterior walls. It wouldn't be necessary in dry interior spaces.
