"Owners did the estimate, were on site for the insulation install...what more can be said about customer service! They were 5+. Now I must tell you about the job...it was difficult adding insulation to the underside of floor boards in our crawl space. Other insulators said it couldn't be done. Kelly took her flashlight, measuring tape and looked really hard and said "We can do this!" What a "can do attitude" and they accomplished it. I will definitely use them again and so should you!"

"Salesman was very professional. Showed up in a vehicle worth the name on the side and in a uniform. Made a video of the bad area of our gutters and explained in detail what problems this would cause and had a very good presentation about the company and product."

Insulation questions, answered by experts

High humidity, bad insulation, warmth from sunlight, and poor circulation are all reasons your home’s hotter inside than out. While this is what you want in the colder months, summer can become unbearable if this is a constant. Try to find the cause, but you need to remember that issues like this require a permanent fix (unless you want to bear down during the summer months).

Yes, insulating your pipes can reduce plumbing noises because it dampens vibrations and reduces the transmission of sound, making your home a quieter place. So if you've ever been annoyed by the sounds of water rushing through your pipes or the clanging noises when someone turns on the faucet, insulation can help.

Bathroom wall insulation not only keeps the area temperate, but it also reduces instances of mold, mildew, and rot. Bathrooms, after all, are havens for moisture. With this in mind, it’s absolutely worth it to insulate bathroom walls since it saves money in the long run. You won’t have to hire a pricey mold remediation service down the line. Also, insulation decreases outdoor noise and lowers energy costs.

One of the clearest signs that your insulation isn’t working as well as it should be is a noticeable difference in temperature throughout your home. One room might feel icy while another is hot as Arizona—this indicates that some parts of your home are either retaining or losing heat more than others. Additionally, a sudden increase in your energy bills, evidence of pests or rodents, or evident water damage are other signals that warrant a thorough inspection of your insulation and potential replacement.

Your home's location, budget, and the type of insulation you’re using are just a few of the factors that can help you choose the right insulation. For example, blown-in insulation is typically used in attic spaces, while batts and rolls are ideal for floors and walls. Blown-in insulation is usually a good option if you're adding more insulation to an area that already has some, but not enough.
