AIR SEALING EXPLAINED
Air sealing closes the leaks that insulation cannot fix
If your home feels drafty, rooms never match the thermostat, or the furnace runs nonstop in winter, you are usually dealing with uncontrolled airflow. Air sealing is the service that targets that problem directly.
Most Denver homes leak air through the attic and the top floor. Small gaps around plumbing and wiring, recessed lights, attic access panels, and framing joints add up. In the winter, warm air escapes upward and pulls cold air in from lower areas. In the summer, hot attic air can get pulled into the home through the same paths.
Adding insulation on top of leaks helps, but it does not stop air movement. That is why some homeowners add insulation and still feel drafts, still have hot upstairs rooms, and still see long HVAC run times. Air sealing is what makes insulation and HVAC work like they are supposed to.
Our approach is simple. We identify the main leak paths, seal them cleanly, and avoid the sloppy “foam everywhere” look. You get a clear scope, we protect your space, and we show what was sealed so you know exactly what improved.
If you are planning attic insulation, insulation removal, or a remodel, air sealing is usually the step that makes the rest of the work perform better and last longer.
