"These guys took time from their busy schedule came to my residence on Easter Sunday to give me a price on repairing insulation mess left by previous contractor. They arrived next day and completed the insulation work and did an excellent job at an excellent price. My thanks to Sagittarius air seal thanks again, Michael Duffy."

"I can?t say enough good things about PeakPro Insulation! Before they came out, my attic wasn?t insulated at all and my house constantly fluctuated in temperature. When their team arrived, they introduced me to solar radiant barrier insulation. The difference was noticeable immediately. After the job was done, every room in my house finally felt consistent in temperature, and even my attic felt cooler while they were working up there. On top of that, they left the attic looking beautiful and clean. Highly recommend"

"Roberto was the technician and he was very professional, polite, and personable. He inspected the rest of our system and told us things that needed to be changed or repaired. He showed me pictures of everything. Everything he told me about was accurate. He quoted me a price for R38 insulation , Some of our ducts were plastic and he recommended them to be changed. I agreed completely and didn't know they were plastic. I would have had them done the work but I had no price comparisons to make and besides I didn't have the money right then. So he just finished the vent cleaning and left his card. He did a great job on the vent cleaning and was happy with the work."

Insulation questions, answered by experts

Yes, it is possible to have too much insulation, which can have detrimental effects. While more insulation might seem better for energy efficiency, a home needs to "breathe" or ventilate to release moisture that accumulates inside. Over-insulating can seal a house too tightly, trapping water vapor and leading to several problems, including mold, mildew, and condensation. Homes in warm, humid climates are particularly susceptible to mold, while those in colder climates can experience condensation from temperature fluctuations. Additionally, adding more insulation than the recommended amount for your climate may not provide recoverable energy savings. To avoid these issues, consult a professional insulation contractor who can determine the optimal amount of insulation for your home.

If you’re using faced insulation with paper, face the paper toward the inside of the room during the installation process. 

A good way to remember this is that the paper should face the “warm side” as it’s the vapor barrier, meaning it should face toward where the heat will be coming from.

If you have access to the foundation walls, adding spray foam insulation to your existing unfinished basement or crawl space is straightforward. Replacing existing insulation in your unfinished attic space is possible after removing the old insulation. However, spray foam insulating an existing wall after the drywall is in place isn’t possible unless you remove most of the drywall.

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.

Installing new insulation in a home is worthwhile if your existing insulation is old and has lost some of its insulative capability or if you don’t have insulation installed already. Installing new insulation will boost your home’s energy efficiency, which can reduce your heating and cooling bills and save money on HVAC repair and maintenance in the long run. New insulation also keeps your living space more comfortable, so you and your family will benefit from the work as well. Finally, installing new insulation boosts your home value, making it especially worthwhile if you plan to sell.
