Home energy audits in Cedar Rapids, Iowa
Blower door testing, infrared imaging, and whole-home diagnostics for Cedar Rapids homeowners. Cedar Rapids is a city of neighborhoods, and every neighborhood tells a different story about how its homes were built, insulated, and — too often — left to lose energy through walls and attics that haven’t been touched in decades.
Why energy audits matter in Cedar Rapids
If your home was built before 1980 — which covers a large share of Cedar Rapids’ older neighborhoods — it was almost certainly built to an energy code that bears no resemblance to what’s required today. That’s not a criticism of those homes. Many are beautifully constructed with materials you can’t economically source anymore. But they were built with the assumption that energy was cheap, air sealing wasn’t a concept, and attic insulation meant a few inches of loose rock wool or vermiculite. Here’s what we typically find, by era:
Brick and stucco homes
Mound View, Vernon Heights, Kenwood, Oakhill Jackson: solid masonry walls with little or no wall insulation, balloon framing that turns stud cavities into uninsulated chimneys running from basement to attic, and window openings patched and re-patched over a century.
Ranches and split-levels
SE and NE side, Bever Woods, Time Check: minimal wall insulation, settled or displaced attic insulation, and leaky duct systems running through unconditioned crawl spaces or attics.
Insulated to the standards of the day
Kingston Hills, Cherry Hills: R-11 walls and R-19 attics that fall far short of current recommendations, often paired with original single-pane or early double-pane windows.
Tighter, but not verified
Generally better construction, but we still find disconnected bath fan ducts venting into attics, knee-wall assemblies with uninsulated back sides, and HVAC systems sized for a code-minimum envelope that no longer performs as it did on day one.
The 1920s home that “just felt cold”
A homeowner in the 1st Avenue SE corridor called after being told by an HVAC company they needed a $30,000 geothermal system. They wanted a second opinion.
On site, we ran a blower door test, took infrared images of every exterior wall, measured attic insulation depth, and walked through two years of utility bills. The existing furnace was older but testing within spec. The real problem was the envelope: the home was leaking at nearly 4,000 CFM50, had roughly R-7 of compacted attic insulation, and had no rim joist sealing at all. The drafts at the second-floor baseboards in winter were direct air infiltration from the basement, traveling up through balloon-framed walls.
The recommendation was air sealing, attic insulation to R-49, and rim joist foam — $4,000 to $6,000 of work, not $30,000. The furnace had plenty of life left once the envelope wasn’t fighting it. That’s what an audit is for.

The full BPI diagnostic protocol, applied to your home by a certified Building Analyst who also trains other professionals in it.
BPI training →Blower Door Test
A calibrated fan quantifies your home’s total air leakage. We use 4.0 ACH50 as a practical retrofit benchmark for Cedar Rapids homes.
Blower door testing →Infrared Thermal Imaging
Thermal imaging of walls, ceilings, and floors reveals missing insulation, hidden air paths, and moisture the eye can’t see.
Thermal imaging →Home Energy Score or HERS
A DOE Home Energy Score or HERS Rating available on request when you want a standardized number.
A Report, Not a Pitch
A written report with prioritized, cost-effective recommendations — for a flat $699, any size home. We don’t sell insulation, windows, or HVAC — the audit is the product.
