"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

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.

The best type of attic insulation depends on where you live, your budget, and what stage of construction the attic is in. For example, if you're building a house, then structural insulated panels are a worthy investment since they're easy to install during construction and they're the most energy-efficient type of insulation.  

Additionally, if you live in a very warm climate, then you can potentially save quite a bit of money by opting for reflective insulation, which is more affordable than comprehensive insulation but doesn't work well for cool climates. Blown-in, loose-fill, and spray foam insulation are all great options for attics in moderate climates.

It is possible to insulate your walls without removing drywall, but it’s not a good idea to attempt the work yourself. A professional can use blown-in insulation or spray foam insulation to fill wall voids without opening up the walls, and the option they use typically depends on your climate and whether or not there’s insulation in your wall already that can remain in place. Spray foam insulation costs more and isn’t always a viable option, but it’s a better insulator. Call in an expert to help decide which is right for you.

Yes. Proper, complete insulation will ensure that you trap the most cool or warm air inside your home, preventing high energy bills. In addition, insulation tends to settle and compress, leaving gaps over time; the more you insulate completely during the initial installation, the less you’ll need to do down the line.

The most affordable way to insulate a garage involves choosing cost-effective materials like fiberglass, which comes in batts or rolls and is relatively easy to install. You can often install this type of insulation without needing to add drywall, which helps reduce costs. While a DIY approach might seem cheapest, hiring a professional installer can be highly cost-effective. Experts can accurately determine your garage's specific insulation needs and ensure the best results for your investment, often using batt insulation for the bulk of the project.
