Get a FREE QuoteWhat goes into the cost of insulation in Franklin Lakes?
What you’ll pay for insulation in Franklin Lakes depends on the job in front of us. Attic or wall size, the insulation type you pick, blown-in, fiberglass, or spray foam, and the scope of prep all move the number. If old or damaged insulation needs to come out first, or the attic is tight to work in, that adds to the scope. 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 Franklin Lakes attic?
Most Franklin Lakes attics do best with blown-in coverage and air sealing together, a smart pairing when you deal with the swing from freezing winters to humid summers. It gets into the spaces around framing and wiring that batt insulation tends to miss. Spray foam earns its cost when the roof deck needs sealing or the attic is becoming 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 Franklin Lakes?
For climate zone 5A, where Franklin Lakes sits, the Department of Energy recommends attics at about R-49 to R-60. It’s common to find the custom homes and larger properties spread across Franklin Lakes sitting at only R-19 to R-30, well short of the target. We measure what you have now during the free evaluation and show you exactly where you stand. Topping up to the recommended level may also qualify for rebates through New Jersey’s Clean Energy Program and local utilities.
Which towns near Franklin Lakes do you cover?
We cover Franklin Lakes along with neighboring towns such as Wyckoff, Oakland, Mahwah, Ridgewood, and Ramsey and the communities around them. Not sure if you’re in range? Call (201) 627-0087 and we’ll confirm in about a minute.
Do I have to leave home during the install?
Blown-in attic insulation is typically finished in one day, with no need to pack up and leave. With spray foam, plan to stay elsewhere for about 24 hours during curing. We go over all of that with you up front, before the work is scheduled.
