Air Sealing
Lakewood, CO
Drafts, uneven rooms, high energy waste, and insulation that underperforms usually come from hidden air leaks. Air sealing fixes the gaps that let comfort escape.

The problem
Air leaks make the house feel like the insulation is not working.
A home can have insulation and still feel uncomfortable if conditioned air is escaping through attic penetrations, top plates, rim joists, and hidden gaps. Air sealing targets those leaks directly.
Drafts that keep coming back
Rooms feel drafty even when doors and windows are closed because air is leaking through hidden gaps.
Rooms that never match
One room feels cold, another feels hot, and the thermostat never tells the full story.
Insulation that underperforms
More insulation helps less when air is still moving through the attic, walls, rim joists, or penetrations.
Air leak diagnostic
What we check before sealing anything
Good air sealing is targeted. The goal is not foam everywhere. The goal is to seal the leak paths that actually move air and hurt comfort.
Attic penetrations
We check gaps around plumbing, wiring, recessed lights, ceiling fans, bath fans, and other openings that let conditioned air escape into the attic.
Attic hatch and access points
The attic hatch is a common leak point. If it is not sealed correctly, it can act like an open door between the home and attic.
Top plates and framing gaps
Small framing gaps at the top of walls can leak a surprising amount of air, especially in older Lakewood homes.
Rim joists and lower leaks
Air leaks are not only upstairs. Rim joists and basement edges can pull cold air into the home and make the first floor feel uncomfortable.
Insulation readiness
If you are adding attic insulation, sealing the main leaks first helps the insulation perform the way it should.
What air sealing fixes
Sealing the leaks helps insulation and HVAC do their job.
Air leaks move comfort faster than most people realize. Warm air escapes into the attic in winter, hot attic air can get pulled into living areas in summer, and lower-level leaks can make the whole home feel drafty.
That is why adding more insulation without sealing the biggest leaks can disappoint. Insulation slows heat transfer, but air sealing helps stop uncontrolled air movement.
We focus on the gaps that matter most: attic penetrations, attic access, top plates, recessed lights, plumbing and wiring penetrations, rim joists, and other weak points that hurt comfort.

Which service fits?
The right comfort fix depends on where the air is moving.
Air leaks in the attic
The main service when drafts, temperature swings, and hidden attic leaks are causing comfort problems.
Thin attic insulation
Best when the attic also needs better depth, better coverage, and a stronger thermal layer.
Low attic depth after sealing
Often the next step after sealing attic leaks, especially when coverage is thin or uneven.
Drafts from below
Worth checking when cold air is entering through rim joists, lower-level gaps, or basement edges.
Cold floors and lower spaces
Important when the comfort issue is tied to air movement and weak insulation under the home.
Air sealing often pairs with attic insulation, basement insulation, and crawl space insulation because air leaks can come from more than one part of the home.
Cost and scope
Air sealing cost depends on access and leak points.
The price depends on where the leaks are, how accessible they are, and whether the work is attic-only, basement-related, or part of a larger insulation project.
Access
Attic access, crawl space access, basement access, and tight areas can change the scope.
Leak volume
Some homes need a few major gaps sealed. Others have many smaller leak paths throughout the attic or lower level.
Project pairing
Air sealing is often done before attic insulation, blow-in insulation, or insulation removal.
Material and method
Different gaps need different sealing methods. The goal is a clean, durable seal.
Ventilation considerations
Proper air sealing targets uncontrolled leaks without ignoring ventilation needs.
Best combo: air sealing first, then attic insulation or blow-in insulation. Sealing first helps the new insulation perform better.
What matters
The best insulation work starts by stopping the air leaks first.
Benefits
What better air sealing helps with
Fewer drafts
Air sealing targets the gaps that let outdoor air, attic air, and basement air move through the home.
More even comfort
Sealing leaks helps rooms hold temperature better and reduces hot and cold zones.
Less energy waste
When uncontrolled airflow drops, heating and cooling do not have to work as hard to keep up.
Better insulation performance
Insulation works better when air is not moving through it or around it.
Why Palencia
Targeted sealing, clean work, and clear recommendations.
You should know what is being sealed, why it matters, and what it should improve. We inspect first, identify the biggest leak points, and explain the right order of work.
Air sealing is not about filling every visible crack. It is about sealing the gaps that actually move air and affect comfort.
Process
Quick, targeted, and clean
Inspect
We look for the biggest leak points, attic access gaps, penetrations, top plates, and lower-level air movement.
Prioritize
You get a clear scope showing what should be sealed first and why it matters.
Seal
We seal the right gaps cleanly, without the sloppy foam-everywhere approach.
Review
Before we leave, we review what was sealed and explain any next steps that could help.
