"These guys are great! Manny showed up on time for his estimate, gave me a price on the spot, and talked things out with me to make sure that I understood exactly what he was including in the insulation project. He was able to meet my timeline, which was quick, and finish the project on time and as promised. He was very communicative throughout the process and pleasure to deal with. His crew was polite and worked hard. I am VERY satisfied with the crew and the workmanship."

"I researched and found Devon and his company were very well reviewed and he was great on the phone. We have a 1904 home with vermiculite and old batting for insulation in the attic. Devon came out to the house and was planning to do the removal of the old insulation but the vermiculite was determined to have asbestos, so we had everything in the attic remediated. Devon told me about the ZAI Trust and I was able to submit a claim for the abatement and reinsulation. Devon also discovered that a small roof off the kitchen/dining area was uninsulated as well as the dormer roof and the ensuite below it. We had to reschedule suddenly due to Mum being admitted to the ER, and Devon had no issue with this at all, and was very supportive. Devon and his team did an amazing job! What great people! They worked so hard and the spackling job to cover the holes was terrific. We just primed and painted. Devon will be back here to review the insulation status in the rest of the home, as the old foam insulation may need to be supplemented. I'd hire Go Go Green Insulation in a heartbeat and have already recommended them to a couple of neighbours. Old home, apt. or new build, these guys are the BEST!"

Insulation questions, answered by experts

Yes, cold walls are a common indicator of poor or inadequate insulation, especially if the walls feel significantly colder than the air in the room. This suggests that heat from your furnace is escaping rather than being retained. The issue could be that the walls have no insulation, or that the existing insulation is old or has been damaged by water, moisture, or pests. Your best course of action is to hire a professional to investigate. An insulation contractor can determine if you need to add or replace insulation and can often perform the work without creating large holes in your drywall. If you suspect the problem might also be related to your heating system's performance, an HVAC technician can take a closer look.

The amount and type of insulation your home needs depends on your location, climate, and the specific installation area (attic, walls, or floors). Your local building code will typically determine the minimum required R-value. For specific recommendations, Energy Star suggests the following R-values: homes in the Southern U.S. should have R30 to R60 in attics and R13 to R25 in floors and walls; homes in moderate climates need R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require R49 to R60 in attics and R25 to R30 in floors and walls.

An insulated garage door is a great long-term investment if it’s within your budget. They save energy and give the door year-round usability. In other words, the door pays for itself after a few nasty winters. Most modern garage doors already have a fair amount of insulation, so look into those options if you don’t feel comfortable splurging.

According to a report from Energy.gov, radiant barrier installations can save between 5% and 10% on your energy bill each month that your HVAC cooling is in operation. That fact can mean savings of up to more than $325 per year for homes that experience frequent direct sunlight and high summer temperatures. 

Buying a house with vermiculite insulation is not recommended without going through a proper testing process. Vermiculite insulation can potentially contain asbestos, which poses health risks when disturbed. While it is possible to purchase a home with vermiculite insulation, you should have it tested for asbestos, and ensure proper containment if asbestos is present. If asbestos is present, you will want to hire a professional to remove it, ideally before you move in.
