A blower door test is the only reliable way to measure your home's actual air infiltration rate. Urbanfoam Insulation performs certified blower door testing in Saint Martin, MN, producing an ACH50 reading and a mapped report of every significant leak location — the diagnostic foundation for any effective weatherization project.
Most homeowners have no objective data about how airtight their home is. They notice high energy bills, uneven temperatures, or drafts near windows, but cannot pinpoint the source. Without a blower door test, any air sealing or insulation work in Saint Martin is essentially guesswork — money spent on fixes that may not address the actual problem locations.
Air infiltration accounts for 25–40% of the energy load in a typical home. Unlike conductive heat loss through walls, which can be estimated from insulation R-values, air leakage is highly unpredictable. It concentrates at hidden junctions: the top plates where walls meet ceilings, the sill plate where framing meets the foundation, around recessed light cans, at plumbing and wiring penetrations, and through dozens of other bypasses that are invisible from inside the living space.
New construction in MN is subject to increasingly strict air tightness requirements under current energy codes. Builders who skip a final blower door test before closing often discover failing results during the required inspection, creating costly change orders and schedule delays. Urbanfoam Insulation works with builders throughout Saint Martin to perform pre-drywall and final blower door tests, identifying failures early when they are inexpensive to correct rather than after the walls are closed.
Rebate and incentive programs available to homeowners in Saint Martin, MN through utility and efficiency programs frequently require documented blower door test results both before and after weatherization work. Without that baseline measurement and a post-improvement retest, homeowners cannot claim the savings they have earned. We provide the documentation these programs require.
We close all exterior doors, windows, and fireplaces. Interior doors are opened. The calibrated fan unit is mounted in an exterior door frame with a pressure gauge (manometer) connected to measure indoor-outdoor differential.
The fan runs in both directions at 50 Pascals of pressure differential. Software logs the airflow rate required to maintain that pressure — the CFM50 reading — which is converted to your home's ACH50 rating based on conditioned volume.
While the fan holds pressure, our technician walks the home with a smoke pencil or thermal camera to identify the specific locations where air movement is greatest, mapping each zone for the repair report.
You receive a written report the same day, showing your ACH50 result, a comparison to code targets, and prioritized leak locations. If air sealing is needed, we provide a scope and estimate at the same visit.
We schedule blower door tests in Saint Martin within the week. For new construction with inspection deadlines, we prioritize accordingly.
When we perform air sealing based on our blower door test findings, the work is covered by a written workmanship warranty. We retest to verify results.
Our technicians hold all required state contractor licenses and we carry full liability and workers' compensation coverage for every job in MNCode.
Testing is performed by our own trained technicians — not subcontractors. Consistent personnel mean consistent, documented results.
Our blower door test price covers the full test, both pressurization and depressurization readings, leak zone walk, and same-day written report. No add-on fees.
Equipment setup and breakdown causes no mess. We leave the test area exactly as we found it and remove all equipment before delivering your results.
Air tightness targets in MN are shaped by the climate zone's balance between heating and cooling seasons. Tighter homes perform better in both extremes, but over-tightened homes without adequate mechanical ventilation create indoor air quality problems. Our technicians understand the local balance: we help Saint Martin homeowners and builders reach the efficiency they need without creating the moisture and air quality issues that come from sealing a home beyond its ventilation capacity.
Construction methods common in MN — platform framing with open cavities, older slab-on-grade foundations, and the variety of HVAC configurations used across different eras of construction — each produce distinct air leakage signatures. An older bungalow in Saint Martin leaks differently than a 1990s two-story or a new construction townhome. Our technicians recognize these patterns and know where to look for the dominant leak pathways in each building type, rather than following a generic checklist.
For homeowners pursuing utility rebate programs in Saint Martin, MN, our blower door test reports are formatted to meet the documentation requirements of most common program administrators. We note this at scheduling so the report we deliver has the fields your program needs and is ready to submit without additional work on your end.
"We hired Urbanfoam to run a blower door test before starting a major insulation upgrade. The leak map they gave us changed our entire plan — half the bypasses were places we never would have looked. Worth every dollar as a first step."
— Homeowner in Saint Martin"Our builder used Urbanfoam for the required blower door test on our new construction. They caught a couple of issues during the pre-drywall walkthrough that were fixed on the spot. Final test came in at 2.1 ACH50 — well under code."
