"Zach did an outstanding job identifying the problem and suggesting a solution. He even came out on New Years day to remove the trapped animal when road conditions were less than optimal! He is thorough, professional and reasonably priced. He always kept me in the loop when work was being done and I would highly recommend him to anyone with a game control problem."

"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

Air sealing isn't necessary for attic insulation, but it's incredibly helpful since it can help you identify and patch any existing air leaks. Failing to find these leaks before adding insulation can render your insulation less effective, leading to higher energy bills and potentially costly repairs down the line.

One of the biggest disadvantages of glass garage doors is that they are not the best at insulating your garage. In the summer, heat can enter through the glass, while in the winter, heat can escape through the glass, increasing your electricity and gas bills as you crank up your HVAC unit. You can help mitigate the poorer insulation by investing in insulated glass and insulating your garage.

Ductwork sweats due to a temperature difference between the air inside the ducts and the surrounding air, similar to how a cold drink develops condensation in the heat. This sweating is a sign that your HVAC system is not operating at peak efficiency. The best way to keep ductwork from sweating is to wrap it in proper insulation, which also improves your system's energy efficiency. Another option is to close off your crawl space and install a dehumidifier to dry the air and lower its dew point.

Polyisocyanurate foam, or polyiso for short, has the highest R-value per square inch: 6.5 to 6.8. Polyiso is a rigid foam that comes with a reflective foil on both sides to serve as a radiant barrier. Given its high R-value, rigid foam is usually meant for foundations and basement walls.

Yes, brick houses are better insulated, because the bricks slow down the passage of air from the outside to the inside and vice-versa. This helps to stabilize the internal temperature of the home. When combined with proper residential insulation, brick houses are more efficient and better insulated than other types.
