"The professionalism and quality that the Insulation Labs team demonstrated from beginning to end should serve as a Master Class for any other service oriented company. Scheduling the estimate was effortless with clear, helpful and efficient communication from Diana, their first line of contact. Abraham arrived to do the estimate visit with kind patience and knowledge. He took the time to help us figure out how best to approach the insulation and was more than willing to answer all of our many questions. When we received the estimate we were appreciative of how easy it was to read and understand what the plan was. We knew exactly what to expect and how much it would cost. Today was the day of the insulation. Chris, Tzoc, and Moises spent a long full day doing the entire job. Throughout they were kind, professional, and did an outstanding, neat job. At all times, they cared for our space as if it were their's. We are so glad we chose Insulation Lab. There is no question we would recommend them to anybody."

"We moved to our home few months ago and had to replace the HVAC system. The AC Company had to go inside the attic and they noticed a problem with the insulation there. We asked around some friends and family members and we came across Attic Masters. From the other 3 companies that we spoke and met with, Adam was the most polite, friendly and knowledgeable. Their price was also cheaper than the rest so we scheduled them to come and do the job. Our referral was absolutely correct! They were an amazing crew! They didn't just replace the insulation. The last owners of the home had rats problem in the attic which caused a bigger problem than we thought and we had to secure not only the house but also the insulation. Adam's crew took all the old and bad insulation out from the attic and house in a very careful way (inside bags). They sanitized the entire attic and then rat proofed it with special mesh wiring to make sure we would never have this problem again. After this was completed, they laid the new insulation in and even insulated the walls of the attic. I HIGHLY recommend Attic Masters to anyone looking to remove and install insulation."

"Adam and his team of workers gave me a great deal on replacing the insulation in the attic. We had a leak in one of the fire alarm sprinklers that caused the insulation to be bad and smelly. 
We spoke to Adam about the problem and he sent his employee (Luis) to come over and check the problem in order to provide us  with a quote.
The quote that Adam was able to give us was very good and we approved the work. He than sent 2 workers to do the job and it was done in 2 days after they had to clean everything in the attic and to try it before they placed the new insulation.

"My old door insulation was getting ineffective, and I contacted Reliable to do something about it. It only took them about an hour to come to check it out and have it replaced. My house is now much warmer."

"I can't edit previous review so posting new one: I am revising my previous review. After posting my first review, Danny in Customer Service at Home Comfort USA contacted me. Danny very patiently listened to my situation and frustration and told me he would look into it, but wouldn’t “leave me hanging” and would call back. He did call back and fast-tracked a HVAC technician, Jad, to come out, who was great and called in a higher-level technician two days later. Then the higher-level technician came out a couple of days after that and found we did need a leaking core replaced and said Danny would call me. Danny did call me and went above and beyond to get the part replaced under the manufacturer’s warranty. Two days after that, Home Comfort USA came out, replaced the core, tested our HVAC, and mitigated the labor. We are now VERY happy customers with Home Comfort USA and very grateful for Danny’s great customer service and intervention. I am writing this review on a day in the mid-90s with our HVAC system keeping us VERY comfortable. Thank you."

"Zohar at Best builders group and his crew did a wonderful by remodeling our 3 bathrooms. We couldn’t be more pleased and satisfied with the overall experience we had with them and with the office staff that were involved at our project. Zohar is indeed a great person with a special character that made this involvement great and stress free. We know that if we will ever plan on doing another remodeling project, Zohar and his crew will be the only people we will hire for that. Many thanks."

Insulation questions, answered by experts

Yes! Outdoor faucet covers work by enclosing the faucet with a thick, insulating material that will keep the faucet warmer than outdoor temperatures. They need to be sealed tightly against the house to work properly, though, so be sure to tighten the rubber strap or drawstring on the insulation cover to best protect your faucets.

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.

Don’t install insulation near water heaters, oil burners, or any other object that gets hot. Many insulation materials are fire-resistant, but not entirely fire-proof, so you should take precautions to keep hot things away from fiberglass. This is also why it is imperative to box off lighting fixtures and breaker boxes.

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.

R-30 insulation is better for higher thermal resistance, but whether it’s "better" depends on the application. R-30 is much thicker and suited for areas like attics or floors in cold climates, where more insulation is required. R-13, on the other hand, is thinner and works well for 2x4 walls or milder climates where less insulation is sufficient. Choosing between R-13 and R-30 depends on the area being insulated and the climate. For example, R-30 provides more insulation but may not fit everywhere in your home.
