"We called Home Seal to consult on weatherization and insulation for our 1920s bungalow. The advice was great and we hired them to insulate the rim joists between our basement and first floor as well as adding cellulose insulation to our attic space. The communication throughout this project went well and the work was completed as scheduled. We would highly recommend Home Seal for weatherization and insulation projects."

"Ryan, Miguel, Luis and staff did a great job removing old insulation, inspect, clean & disinfect, spray foam, and blow in new insulation. They were efficient, kept me informed, cleaned up well, and addressed minor issues after the completion was complete. I had planned to also spray foam the basement, but we could not vacate the house (fumes) with a member in hospice. This will be done as soon as we are able. Highly recommended!"

"Ryan did our estimate, and was very efficient. Andrew and Evan did the insultation work and did a fantastic job! It was a large area to get prepped and then to insulate and they did a great job every step of the way! Our entire home is now at a R50+ insulation level, as opposed to the R25-30 and 0 values we had before. It will be interesting to see what sort of impact the newly insulated garage and 3 season porch has on the comfort level in the main house. The team did a great job for us and I would recommend them to anyone considering insulation!"

Insulation questions, answered by experts

STC (Sound Transmission Class) is a rating that describes how well a building material or assembly blocks airborne sound. A higher STC rating means less noise will pass through the material, providing better sound reduction. This rating system applies to various building components, including windows, doors, flooring, drywall, and insulation.

For context, a typical single-pane window has an STC rating of around 25 (where normal conversations are audible), while a well-sealed, double-pane window can exceed STC 45 (blocking loud speech and most music). It is important to note that for some products, like soundproofing drywall, the STC rating refers to the entire wall system, not just the individual panel.

Additionally, STC ratings are most effective for measuring sound reduction at mid-to-high frequencies, such as human speech, and may not accurately reflect how well a material blocks low-frequency sounds like bass music or thunder. Because of these factors, it is recommended to consult a professional to determine the right STC-rated materials for your specific soundproofing needs.

Yes, crawl space insulation is worth it if installed correctly. Installing insulation in your crawl space will improve the air quality, help stabilize your home's temperature, lower your energy bills, and prevent pests from entering your home. Though you’ll pay more to install insulation initially, the savings you get from installing insulation can help offset those initial costs over time.

Insulating under a concrete slab foundation is a great way to improve the energy efficiency of your home, but it isn't necessary for outdoor projects like driveways, patios, sidewalks, and walkways. If you’re pouring in cold weather, insulating under the slab can help prevent heat loss from the concrete, aiding in proper curing. Along with accelerants, this can be a good way to ensure strong concrete despite pouring in the cold.

In some cases, yes, insulating an unheated garage can lead to mold and mildew. The issue with insulating a garage is that the interior will warm up and cool down more slowly than the exterior air, which can cause condensation inside the space. Where there is moisture, there is likely to be mold and mildew over time. Installing a vapor barrier can help avoid moisture and mildew problems in an insulated garage.

The cost to install a radiant barrier ranges from $700 to $2,800, depending on the size of your roof and the type you choose. Most people pay an average of $1,700 to install a radiant barrier. Foil options, both single- and double-sided, cost between $0.10 and $0.90 per square foot, while spray-on options start at $0.60 and go all the way up to $1 per square foot—which can add up quickly.
