The Smith family of Mentor, Ohio, was facing high winter heating bills and uncomfortable drafts—until they called Airlock Insulation. With our expert cellulose insulation and personalized service, they turned a drafty home into a cozy, energy-efficient sanctuary—and reduced their energy bills by nearly half.
Meet the Smith Family
When Tom and Erica Smith moved into their 1970s split-level home, they quickly realized their energy bills were unusually high. “We’d wake up in the morning and it felt like we left a window open,” said Erica. Their gas bill for January alone had topped $400, and despite running the furnace constantly, their upstairs remained chilly.
Identifying the Problem
When they reached out to us at Airlock Insulation, we started with a free attic inspection, and the family opted for our full energy audit using our thermal imaging camera and blower door test. What we found was a classic case of inadequate attic insulation, air leakage around can lights and attic hatches, and a poorly insulated knee wall off the upstairs bedrooms.
These are exactly the kinds of invisible problems most homeowners miss—but they’re the ones that cost the most on your utility bills.
The Airlock Solution
After walking the Smiths through our findings, we recommended our full attic air seal and Nu-Wool cellulose blown-in insulation upgrade.
Here’s what we did:
- Air Sealed all penetrations: including wiring holes, pipes, vents, and light fixtures
- Installed ventilation chutes to ensure proper airflow from soffits to ridge
- Blown in 15 inches of Nu-Wool cellulose, achieving an R-49 rating
- Insulated and weatherstripped the attic hatch
We completed the work in just one day and left the home spotless—no insulation dust or debris.
Results: Immediate and Lasting
Two months later, the Smiths called us again—not with a problem, but with thanks. Their February bill was just under $250, a 40% drop from the year before. “And the comfort difference is night and day,” Tom told us. “Our bedrooms are finally warm.”
We returned in the summer to follow up, and the results were just as impressive. With their AC running less, their electric usage also dropped noticeably.
Why It Worked
Our approach isn’t just about adding insulation—it’s about building an energy envelope that keeps your conditioned air in and extreme temperatures out. Nu-Wool’s mold-resistant, dense-packed cellulose doesn’t just sit on top of your ceiling. It seals, insulates, and protects.
And with our custom blower door testing, we were able to quantify the improvement, showing a 35% reduction in air leakage.
