"This firm did a great job for me. They were very prompt did what they said they would do. Added insulation to the Attic to get up to R 49. They fixed a few baffles in the Attic as well. Cleaned up after themselves. The pricing was very competitive. No hassles or strong arm salesmen. I would strongly recommend them for blown in insulation work. Jason was very professional in his handling of this project."

"One of the best experiences we've had with work done in our home. Zac and the team from Foam Co went above and beyond for our project - removing the old insulation from our attic and installing new insulation. They arrived exactly at the agreed on time, took care to protect our home from any mess or damage, and completed the entire project in just a few short hours. All of the team members were polite and kind. They went above and beyond to clean up at the end of the project and to make sure we were satisfied with their work. We will absolutely hire them again in the future!"

"I chose Carico Drywall because of his attention to detail, the fact he came out to give me an estimate, and the fact that he uses Union Drywall Installers. He was my 3rd bid in my buildout for my garage, and he was the highest bid by far. But the fact that he came to my house, met with me, explained and asked good genuine questions proved to me that he was the correct person to do the job. My garage is 1500sqft (30 ft deep , 50 ft wide) ceiling height is 18ft. At the peak, its roughly 22ft. I used R21 batting in the walls and 6 to 7 inches of open cell spray foam in the ceiling. The shop was drywalled with 5/16 inch drywall, no real need for anything thicker since the insulation keeps most sound dampened. I didnt tackle the drywall, because I felt like that would have taken me forever. Would i recommend Carico to do more projects? Yes I would."

Insulation questions, answered by experts

Closed-cell spray foam insulation itself serves as a vapor barrier (or vapor retarder). However, you may need to install a vapor barrier if you have open-cell spray foam insulation. When in doubt, work with a professional insulation contractor, as they can provide more detail about the specific needs of your home in your climate.

Generally, the cost of ice dam removal is not covered by homeowners insurance because it is often considered preventable maintenance. However, the damage caused by ice dams is frequently covered. Depending on your policy, this can include interior water damage, roof collapses, and damage to shingles. Coverage for personal belongings affected by leaks may vary. It is important to check your policy details or contact your insurer to confirm what your plan covers. Keep in mind that any damage resulting from a DIY attempt to remove an ice dam will likely not be covered.

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.

Whether you should remove old insulation before blowing in new insulation depends on your particular situation. Fiberglass insulation attracts insects and mold over time, so if it has been decades since your last insulation upgrade, consider removing the old materials before placing the new ones. However, most types resist mold, insects, and mildew, so once you get the go-ahead from your contractor that your space is free from all three, feel free to install the new insulation directly on top of the pre-existing materials.

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.
