Attic Air Sealing in Tulsa, OK

Hot air rises out of a house in winter and gets pulled in from the attic in summer — this is called the stack effect, and it runs through every unsealed gap around light fixtures, plumbing penetrations, and top plates. Insulation slows heat transfer but doesn't stop air movement. Sealing those gaps does, and it often cuts energy waste more than adding insulation thickness alone.

When to Call

When You Need Attic Air Sealing

The upstairs stays significantly hotter than downstairs all summer long
You can feel air moving through recessed lights on the ceiling
Energy bills are high even after adding blown-in insulation in past years
Dust accumulates quickly on upper-floor surfaces and ceiling fixtures
A previous energy audit identified air leakage but nothing was done about it
The attic hatch has no insulation or weatherstripping around it at all

How It Works

Our Process for Attic Air Sealing

1

Attic assessment

We get into the attic and identify every penetration — plumbing stacks, electrical chases, HVAC boots, top plates, recessed lights, attic hatches.
2

Determine sealing approach

Some gaps get closed with spray foam directly. Others need a combination of rigid blocking and foam. The method depends on the gap size and location.
3

Move existing insulation

If blown-in insulation is covering the penetrations, we move it aside to access the gaps. It gets replaced after sealing is complete.
4

Seal all identified penetrations

We work systematically across the attic floor, sealing everything we found during assessment. Gaps around top plates are one of the biggest leakage points.
5

Replace and regrade insulation

Disturbed insulation is replaced and redistributed evenly. We don't leave it piled in corners from being moved out of the way.
6

Final check

We do a walkthrough from the attic before closing up to make sure nothing obvious was missed and the hatch itself is addressed.

What's included

Full attic walkthrough to identify and document all air leakage points
Spray foam sealing of all penetrations identified during assessment
Rigid blocking plus foam on large gaps where foam alone won't hold
Reinstallation of any existing blown-in insulation moved during the job
Attic hatch weatherstripping or insulation cover if not already present

What's not included

Adding new insulation depth beyond restoring what was moved — quoted separately
Repairs to damaged ductwork found in the attic during the job
Roof deck spray foam — that's a different scope with different ventilation implications

Real Situations

Common Scenarios in Tulsa

A homeowner in the Pearl District has a 1940s house with open-bay framing and no blocking at the top plates between floors.

Older homes like this often have completely open stud cavities running from the basement to the attic — basically chimneys built into the walls. We close those cavities at the attic floor with rigid board and foam before touching anything else. That's where most of the leakage is coming from.

A homeowner in East Tulsa added twelve inches of blown-in insulation two years ago but saw almost no change in summer bills.

Extra insulation on top of a leaky attic floor rarely delivers the expected results. The air still moves through the gaps — it just travels through the insulation on its way. We seal the penetrations first, then assess whether the insulation depth is actually adequate.

A family in Midtown notices the second floor of their two-story is unbearable in July even with the AC running constantly.

Two-story homes in Tulsa get hit hard by the stack effect because the attic is directly above the living space. We access the attic and seal the ceiling plane systematically. Combined with adequate insulation depth, this usually makes a noticeable difference in the first full summer after the work.

Tulsa Context

Why this matters in Tulsa

Most Tulsa homes built before 1985 were framed without much attention to air sealing at the ceiling plane. Oklahoma's energy codes have tightened since then, but existing housing stock is largely untouched. The temperature swings here — from single digits in winter to over 100 in summer — mean the stack effect is running hard in both directions, and the energy waste adds up.

Straight Talk

About pricing & scope

The time and material involved in attic air sealing depends heavily on how many penetrations exist and how accessible they are. Older homes tend to have more gaps and worse access. If we find damage to sheathing or framing during the work, we'll document it and let you know before moving on.
