"They showed up exactly when they said they would. They were efficient, neat and made sure to send me pictures in the various stages of execution. And they cleaned up better than when they found the area. I would highly recommend them. I wish he did more than insulation because he would be my go-to guy for all house related needs."

"They insulated my attic, which was done very well and efficiently. But I was most impressed by the consultation they gave on the insulation issues on my first floor. The guy, Brad, gave quality free advice rather than making up a huge project that his company could profit from. Will be hiring them for my next insulation project!"

"It went well. Was $1,750 for taking out the insulation and putting the blown-in cellulose insulation in. They were quick and it only took them about 2 hours. The workers didn't know that the present insulation was to be taken out. It wasn't on the contract, but the salesperson should have communicated that to the workers. Once I explained that that is what the salesperson said would happen, they were OK with doing it. The company owner did not show up on the day of the project. Other than those 2 things, I think they did a good job."

Insulation questions, answered by experts

Your house may be cold even if the heat is on because of bad insulation, gaps in doors, small holes pulling hot air from the home, or excess humidity. The heater itself might be malfunctioning. For this problem, you’d need to talk to an HVAC pro. If you have a gas heating system (most do) this should be considered an urgent job as natural gas could be leaking in your home.

DIY installation is not recommended, as professionals ensure even distribution, proper sealing, and compliance with building codes.

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.

Experts use advanced techniques and tools to assess existing insulation levels and identify gaps. They implement strategic placement of new insulation to ensure complete coverage, optimizing thermal resistance and energy efficiency.

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.
