Air leaks are invisible energy thieves in Roseville homes. Roseville occupies a flat plateau between Minneapolis and St. Paul, and its post-war homes were built before modern energy codes, making them among the least insulated in the metro. The stack effect — where warm air rises and escapes through the attic while cold air is pulled in through the foundation — can exchange the entire volume of air in your home multiple times per day. For Roseville's rambler homes from the 1950s-1960s post-war suburban boom era, which were built before air barriers were even a concept, this means enormous energy waste.
RetroGreen's air sealing service targets the specific leakage points in your Roseville home using calibrated blower door testing and thermal imaging. We identify and seal gaps around attic penetrations, rim joists, recessed lights, plumbing and electrical chases, ductwork connections, and dozens of other common leak sites. This diagnostic-first approach means we find and fix leaks that would be impossible to locate by visual inspection alone.
Air sealing is the foundation of every insulation project we do in Roseville. Without it, even new insulation underperforms because air carries heat right through it. Xcel Energy offers rebates of Up to $1,200 per measure for qualifying air sealing work, and we handle all the paperwork. Call (612) 276-5293 for your free diagnostic assessment.
Key Benefits
Maximizes Insulation Performance
Insulation works best when air isn't flowing through and around it. Sealing leaks lets your existing insulation perform the way it was designed to — without needing replacement.
Lower Heating and Cooling Bills
Reducing air leakage by 15-50% translates directly to lower energy costs. Most homeowners see 15-50% savings on heating and cooling, with the investment paying for itself within 2-4 years.
Improved Indoor Comfort
Eliminating drafts and cold spots creates consistent temperatures in every room. No more throwing on a sweater in certain parts of the house or cranking the thermostat.
Better Indoor Air Quality
Sealing gaps prevents dust, pollen, vehicle exhaust, and outdoor pollutants from entering your home through hidden openings in the building envelope.

Our Process in Roseville
Blower Door Testing and Diagnostics
We install a calibrated blower door fan in your exterior doorway to depressurize the home. Using thermal imaging cameras and smoke pencils, we map every air leak location and measure your home's total air leakage rate.
Targeted Air Sealing
We seal all identified penetrations with professional-grade caulk, spray foam, and weatherstripping. Focus areas include attic bypasses, rim joists, electrical and plumbing penetrations, ductwork connections, and recessed light housings.
Verification Testing and Results
A post-sealing blower door test measures the exact improvement. We document before-and-after air leakage rates and provide you with a detailed report showing the work completed and the measurable results achieved.
