"Abraham and his team, Will and Josh, did a great job of removing old insulation, sealing air leaks and adding new insulation to the attic in my 46 year old home. The old insulation was blocking air flow through the attic and this needed to be addressed, which they did. They were very professional and hard-working. Communication was excellent and everything was well explained and the process photographed. We are glad we hired Abraham for this project!"

"The installers were careful, courteous, & thorough. They left the premises clean & uncluttered. I can't wait to see the difference in our heating bill. They installed spray foam in the rim joist, a small ceiling in the basement & the walls in a crawl space."

"Abraham and his team were a fantastic help. Their service was life changing for our family. We live in a 120 year old home that had almost no insulation in the walls. Our HVAC could never keep up on cold, windy days. The last 3 winters there were times we had to go stay elsewhere as the home was too cold. Fast forward to this winter, after they completed the work we saw an immediate return. Bills went down and the home is comfortable. Heck there were times our HVAC stopped since it was so warm! They were very professional and worked around our hectic schedule. I would fully recommend them to anyone in need of insulation services."

Insulation questions, answered by experts

At a minimum, blown-in insulation lasts 20 to 30 years. Cellulose and sheep’s wool come from natural materials, so they likely max out at around 30 years. Fiberglass and rockwool feature artificial materials that boast lengthy lifespans, up to 50 years, or even longer in some cases. As always, this timeline assumes you don’t run into any issues, such as flooding or mold, that shorten the lifespan.

Yes, exposure to fiberglass insulation can cause harm to your skin and eyes. However, this typically refers to the fiberglass insulation that is mostly used in walls and attics. Fiberglass doors don’t pose risks for fiberglass exposure because they're fully encased in polymer cladding.

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. 

Asphalt roofs provide better insulation than metal roofs, but that doesn’t always mean that asphalt roofs are better for reducing heating and cooling bills. In hotter climates, metal roofs will usually be better for home efficiency because the material reflects more sunlight and reduces solar heat gain. In colder climates, asphalt roofs are sometimes superior in terms of efficiency because they introduce more solar heat gain to your home and have greater insulating capabilities. However, metal roofs installed with an air gap can provide similar levels of insulation.

Spreading tin foil over your windows works similarly to radiant barrier insulation, but not as well. It will reflect some of the sunlight that would otherwise come through the glass and warm up the inside of your home, so it might help a little to keep your home cool in the summer. However, the appearance isn’t preferable to blinds or drapes that can offer the same benefits. You might also consider tinting your windows instead, which is a more aesthetically pleasing change that can still block a good portion of the solar heat coming through your windows.
