Air Seal Tech

Air Seal Tech is an insulation contractor serving Minneapolis–St. Paul, helping homeowners eliminate drafts, lower energy bills, and boost year-round comfort through targeted air sealing and attic/basement insulation. Schedule an energy assessment to pinpoint leaks (ask about blower-door testing) and get a written plan with recommended R-values, ventilation upgrades, and material options like cellulose or spray foam. Ask about project timelines, post-job cleanup, and warranties, and see if they can help you capture Xcel Energy or CenterPoint Energy rebates to reduce your out-of-pocket cost.
