"Received a call back the same day I put in the request. Came out next day to give estimate. Received written bid within 2 days. Once I accepted, they had a cancellation from someone else and came out the next day. On time, professional, cleaned everything up. Hugo and Gabe are top notch! Very efficient, detail oriented and friendly. Insulation has made a big positive difference in my heating bill already!"

"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."

"Sales visit was pushy, offering 10% off if I signed that day. I regret giving in. I went with single hung for affordability, but I would have preferred double hung. I wish someone would have told me that I might resent the single hung over time.

Installation was done by one man. He was friendly and capable, but he did run short on time. At the end of the day he asked if he could skip sealing the interior with caulk. He offered to leave caulk for us to finish up ourselves. I allowed this, but found that my caulking skills are not as neat as a professional! I regret this.

He completed the vinyl window wrapping. The product was not vinyl coated metal, but just vinyl, so the wrapping does not have crisp, clean corners. He used clear sylicon caulk on the wrapping. At first the caulking looked nice, but it has collected dirt over time and now looks very messy. He used an abundance of caulk and nails. Over time, I have become dissatisfied with the wrapping.

The insulation that Sears installs with the windows is only fiberglass stuffing. I would prefer foam fill. The windows are good quality, not excellent. I feel that the UV protection coating does add a dark tint. I wish I had known that there are different methods of UV protection and not all involve a dark tint."

Insulation FAQs, answered by experts

The most obvious con of injection foam is the cost. It’s much more expensive to install than fiberglass or spray foam, but it may be your only option (unless you want to remove entire walls around the home). Another con is that it involves drilling into existing material, which has to be repaired after the foam is injected. Some injection foams are made from products that aren’t environmentally friendly, and improper installation can lead to trapped moisture, which can lead to expensive mold remediation down the road. 

Fiberglass is the best insulation for HVAC ducting because it's inexpensive, widely available, versatile, and long-lasting. Fiberglass also offers acoustic insulation in addition to thermal insulation, which can contribute to a more peaceful home environment. You can use other materials like mineral wool, but fiberglass is the industry standard.

The ideal temperature for your garage in the winter is between 40 and 68 degrees Fahrenheit. Maintaining a minimum temperature of at least 40 to 50 degrees is crucial to prevent pipes, liquids, and other items from freezing. Low temperatures can also drain your car battery, so keeping the garage stable is vital for your vehicle. While the lower end of the range protects your belongings, the higher end is based on your personal preference for a comfortable space. If you struggle to keep the temperature from dropping below 40 degrees, consider installing a garage heater.

Drywall insulation costs around $1,800, on average, but prices can range from $500 to $4,500, depending on a few different factors. The following things are important considerations to make when pricing out your insulation project:

  • Square footage of insulation

  • Type of insulation 

  • Climate in your area and the insulation R-value required

  • Whether or not your walls are already finished

  • Accessibility of the area 

  • Whether or not you need old insulation removed first

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.
