They were very helpful in determining what I needed. Not once did they try to sell me insulation or services I didn’t need. They worked with my existing insulation and helped bring the costs down. Would definitely use again

Insulation questions, answered by experts

Regular inspections for moisture damage, pest infestations, and proper R-value performance help maintain efficiency.

Unfaced wall insulation is easier to cut and install, making it the better choice for a DIY project. It’s also more affordable. But if it’s unfaced, you’ll likely need to add a vapor barrier to reach your desired R-value and efficiency, as it doesn’t offer any moisture barrier.

Faced insulation uses paper or foil to create a built-in barrier and doesn’t require an extra step. It’s also more fire-resistant and safe. But it’s quite a bit more expensive and a little bit harder to work with as a DIYer.

A garage ceiling needs a vapor barrier if it’s a heated garage or if you’re installing insulation in the ceiling. Without a vapor barrier, you risk moisture issues and mold growth. If you have an unheated garage and don’t plan on installing insulation that could get wet and harbor mold, the ceiling doesn't need a vapor barrier.

The most energy-efficient windows are double—or triple-pane windows with low-emissivity (Low-E) coatings and gas fills between the panes. These windows reduce heat transfer, prevent drafts, and help maintain a consistent indoor temperature. But if replacing windows isn’t in your budget, pairing your existing windows with insulating window treatments can still make a noticeable difference in home comfort and monthly bills.

Yes, proper insulation in your attic or ceiling can help prevent ice dams. When attic spaces are too warm, they cause the snow on the roof over those areas to melt more quickly than the rest of the roof and then travel downward to a colder section of the roof where they refreeze. If less heat is allowed to escape from underneath the roof, snow will melt at a more consistent rate, making ice dams less likely.
