"They are a very professional organization. Their workmen do a very good job and an excellent job of cleaning the area before they departed the job site. I can tell immediately that the extra insulation they placed in the attic is doing its job by reducing our utility bills."

"This crew was very professional in regards to the installation of my blown -in insulation and their interactions with me, but the mud work they did to repair my walls was sloppy. There were large drips of drywall mud on my furniture, on my sinks, on the floors, on the baseboard trim (especially), and splattered on the walls. In addition, the tape they used to hold up the plastic barrier tore the paint off of my ceilings and adjacent walls which now need to be repaired and repainted. They did repair some of the places on the ceiling and the walls, but they still need to be repainted."

"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 FAQs, answered by experts

All garage doors, particularly newly installed models, add value to your home. Higher-quality and higher-priced doors increase the ROI, so a well-insulated custom garage door increases the value of your home more than a poorly-insulated stock model. Updating a garage door boasts the second-highest home improvement ROI, at nearly 95%.

It is normal for the attic to be hotter than the rest of the house in the summer, but only by about 10 or 20 degrees. Attics that aren’t properly insulated or ventilated can reach temperatures of 130 degrees or more which can cause damage to the home’s structure, including the roof, wood framing, and HVAC system.

There are many reasons one bedroom may be hotter than the rest of the house. The sun will quickly heat a south-facing bedroom with a large window, especially if it lacks quality curtains. If the room has poor insulation, this could let more warm outside air in. Upstairs bedrooms are often hotter than ground-floor rooms because heat rises. Finally, rooms further away from the air conditioning unit may heat up a lot if the system is not properly balanced.

When doing any type of project involving mold, it's important to wear the right protective gear. You'll want an N-95 or KN-95 mask to keep yourself from inhaling mold spores, which can be irritating or trigger an allergic reaction in people with weakened immune systems. You'll also want to wear protective eyewear and gloves to limit your contact with mold.

Minimal maintenance is required, though regular inspections to ensure insulation hasn't shifted or deteriorated can improve performance over time.
