"I highly recommend Jason and Craig there at Mold Blasters. They did and absolute phenomenal job on reinforcing the wall in my crawl space that had begun to bow. They also encapsulated the crawl space which makes me feel so good and reassured that no mold will now form. I cannot say enough about this company. Jason is very honest and follows thru with what he says. You don't get that often these days. I would give more than 5 stars if I could. Good honest work. Thanks again Jason and Craigð  ¥"

"Had the whole house insulated in 2016. Just found out that there is now mold in the attic. Have had three different contractors come to look at it and ALL have said the reason is because when the insulation was blown into the attic they did not take the time to rake it away from the soffits. Now I'm faced with a major repair bill of $3000 to eliminate the mold. Plus, to make matters worse, my utility bill did not go down very much after having this done. Only thing I can say is that the house is more comfortable. So beware if you use this company and make sure they install the insulation into your attic correctly!"

Insulation questions, answered by experts

Installing sheets of plywood over attic insulation is a popular choice, especially in storage spaces. That said, insulation works by trapping hot air—so it needs extra space to expand and be effective, or you might reduce the energy efficiency of your home. 

It’s important that you never compress the insulation by installing flooring directly on top of it. In many houses, you’ll need to install a subfloor before putting plywood over insulation in your attic.

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.

The R-value is a rating that measures an insulation's thermal resistance—in other words, how well it insulates. A higher R-value provides more protection for your pipes, and all pipe insulation materials should have an R-value listed on the product description or label. Each insulation type has its own R-value, which typically falls between one and five for most pipe insulation. When making a selection, Energy.gov recommends choosing a pipe wrap that is at least one inch thick, and the International Code Council (ICC) suggests choosing a material with an R-value of at least 3.

Water heater blanket prices range from $20 to $40 on average, though you typically won’t need to spend more than $30 for all the tools and materials required for installation—which include the blanket itself, heavy-duty scissors, and electrical tape. Blankets with higher R-values will also be slightly higher in price.

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.
