Most professional and honest company in Bergen without a doubt! Mark was timely for our appointment and really laid out and explained what needed to be done for me. Definitely will be using Koala Insulation for all my or my businesses needs!
We had an outstanding experience with Koala Insulation in Bergen County! From start to finish, the entire process was professional, efficient, and exceeded our expectations. We used them for our home, and the difference in comfort and energy efficiency was noticeable right away.

A special thank you to Mark—he was absolutely incredible. He was knowledgeable, honest, responsive, and took the time to explain everything clearly. It’s rare to find someone who genuinely cares about doing the job right and making sure the customer is happy.

If you’re looking for insulation services, I highly recommend Koala Insulation. We couldn’t be happier with the results and would absolutely use them again. Thanks again to Mark and the entire team for such a great experience.

What goes into the cost of insulation in Glen Rock?

A few factors set the price of any insulation job in Glen Rock. Attic or wall size, the insulation type you pick, blown-in, fiberglass, or spray foam, and the scope of prep all move the number. Pulling out old material and sealing gaps before we add new insulation can factor in too. You may be able to claim rebates through New Jersey’s Clean Energy Program and local utilities, and we’ll point you to what applies. So rather than guess, we measure your space during a free on-site evaluation and give you a written, itemized quote.

Blown-in or spray foam for my Glen Rock attic?

Most Glen Rock attics do best with blown-in coverage and air sealing together, a smart pairing when you deal with the hard freezes and ice dams a New Jersey winter brings. It gets into the spaces around framing and wiring that batt insulation tends to miss. Spray foam is the better call when you want to seal the roof deck itself or turn the attic into conditioned space. We’ll suggest the right product once we see your attic, not before.

What R-value do I need for an attic in Glen Rock?

Homes in Glen Rock fall in climate zone 5A, and the Department of Energy recommends roughly R-49 to R-60 of attic insulation there. Plenty of the early-20th-century homes near Glen Rock’s two train stations come in well under that, often around R-19 to R-30. The free evaluation includes measuring what’s up there now so you know the real number. Bringing an attic up to spec can also qualify for rebates through New Jersey’s Clean Energy Program and local utilities.

Which towns near Glen Rock do you cover?

Our Glen Rock crew works throughout Glen Rock and nearby areas including Ridgewood, Fair Lawn, Hawthorne, Paramus, and Midland Park. Unsure if your street is covered? Dial (201) 627-0087 and we’ll check in a moment.

Do I have to leave home during the install?

Most attic jobs wrap up in a single day, and you can stay home while we work on blown-in insulation. With spray foam, plan to stay elsewhere for about 24 hours during curing. You’ll know which situation fits your project before we ever book a date.
