"Nick and his crew were so informative and pleasant to do business with. We had attics insulated, new vents installed, and outside blown-in cellulose, and they worked long hours to make sure everything was done correctly. I would definitely recommend this business. A great surprise was how the insulation muffled loud outside noises (fireworks and loud vehicles)."

"This company cares. They put people above profit. I was in a bad situation, after a nasty winter my roof seemed to be disintegrating before my eyes. It went really fast. Then Daryl stepped up to help me out of a difficult situation. Within hours they expedited the crew, and Walter and Lauren ordered materials and made my roof a priority. Now with three days of rain coming I know my house is protected and it looks gorgeous."

"The crew show up early to the job, worked very efficiently, obviously knew how to install their insulation very well! They were very courteous to me as a customer. The issues were that they did not clean up all of their mess ( which blown in insulation would have gone even further if I wouldn't have closed some doors that they left open to carpeted areas. They only swept up the wooden floor and did nothing to pick up where the insulation had blown onto the carpet."

Insulation questions, answered by experts

You’ve likely heard the saying “heat rises”—well, it’s true! This is why it is critical to properly insulate your attic and protect yourself from chilly winter nights. During summer, your attic insulation will also protect against excessive heat gain radiating through the ceiling into the rest of your home below.

Cellulose insulation is usually made from recycled paper products, such as old newspapers, but cellulose might also contain recycled denim. While most homeowners traditionally buy cellulose insulation to use for installation, it is possible to make your own at home with old newspapers, cardboard, a paper shredder, and boric acid (important for fireproofing your cellulose insulation materials).

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.

Insulation is professionally installed by measuring spaces, cutting materials to fit correctly, and placing them without gaps for optimal thermal resistance.

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.
