Air Sealing DFW

Don't insulate over air leaks. That's like putting a band-aid on a leaky boat.

Air sealing is the most important step in attic energy efficiency — and the most overlooked. Insulation slows heat transfer through your ceiling. But air leaks bypass insulation entirely. You could have R-60 insulation, but if there's a gap around your plumbing stack, conditioned air is pouring into your attic.

We seal every penetration between your living space and the attic: plumbing stacks, electrical wiring, recessed lights (with IC-rated covers), HVAC ducts, bathroom fan housings. We use caulk, expanding foam, and rigid barrier materials depending on the size and location of each gap.

The biggest air leaks are usually around the attic access hatch, recessed lighting, and where walls meet the attic floor. These large gaps can leak as much air as leaving a window open year-round. Sealing them is the highest-ROI step in any attic energy upgrade.

Air sealing is always done before adding insulation. Once the insulation is in, those gaps are hidden and much harder to find and seal. This is why our insulation process always starts with air sealing — even if you don't end up needing more insulation, air sealing alone can significantly reduce your energy bills.

Our promise

We air-seal before we insulate. Most crews skip this step. It's the highest-ROI part of any attic energy upgrade.

Frequently asked questions

How much can air sealing save on energy bills?

Air sealing alone can reduce energy bills by 10-20% in many DFW homes. Combined with proper insulation, savings of 30-50% are common.

Should I air seal before or after insulation?

Always before. Once insulation is in, air leaks are hidden and much harder to find and seal. We air seal first, then insulate.

What are the most common air leaks in attics?

The biggest leaks are usually attic access hatches, recessed lighting, plumbing stacks, HVAC duct penetrations, and where walls meet the attic floor.
