"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

Asbestos has many beneficial properties, including fire resistance, strength, and chemical resistance. It is also an excellent insulator, which is why it was used in pipe insulation and other building materials for decades. For all its benefits, asbestos is dangerous for human health, which is why it was eventually banned from use in certain products.

Ideally, you can add new insulation to your existing insulation. However, some circumstances require you to remove old insulation before adding any new insulation: 

  • If the insulation is over 15 years old

  • If the insulation is wet or moldy

  • If it is vermiculite insulation

  • If you see signs of pest infestation

Removing old insulation is best left to a pro who can safely dispose of potential moldy or asbestos-ridden insulation.

Unless your cellulose insulation is wet, moldy, or showing signs of mildew or pests, there’s no need to remove it before adding new insulation on top of it. Inspect your insulation thoroughly before adding the new insulation, and if you’re unsure how to assess the presence of mold or mildew, talk to a mold remediation specialist near you.

Hanging a thick blanket over your windows will help to keep the heat inside, but only a little. Covering the glass will also prevent the sunlight from getting in, which might actually decrease the efficiency of your window overall. If you get to the point where you’re hanging blankets over your window to keep warm, call in an expert to seal around your windows to prevent warm air from escaping. They may also recommend replacing old windows that aren’t as insulative as newer window technology. Sealing a window isn’t terribly expensive and can make a big difference.

When temperatures are too cold, it can keep ice from melting, and products like ice melt and rock salt are ineffective. Water turns to ice in temperatures below 32 degrees Fahrenheit. Ice melts on its own when temperatures reach above 32 degrees Fahrenheit. 

Ice melt loses effectiveness in temperatures below -25 degrees Fahrenheit, and rock salt works in temperatures 5 degrees Fahrenheit and warmer.
