Attic
Attic Insulation and Air Sealing in Houston, TX
A Houston attic in July is the hottest part of your house by a wide margin, and it sits directly above everything you are paying to cool.
Free on-site assessment across Greater Houston. A written scope before anything is ordered.
The work
Seal the roofline, or insulate the floor
There are two ways to insulate a Houston attic, and each suits a different house.
Sealing the roofline brings the attic inside the building envelope. Foam goes against the underside of the roof deck, the vents are closed, and the attic becomes a semi-conditioned space at roughly indoor temperature. If your ductwork and air handler live up there — which in Houston they usually do — this is the version that matters, because it stops your ducts sitting in the hottest air in the county. Open-cell is the usual system at a roofline.
Insulating the attic floor leaves the attic vented and hot, and puts the insulation on the ceiling below. It is cheaper, and it is the right answer when the ducts run inside conditioned space, or when the roof is near replacement and you want to keep your options open. That version is usually blown-in.
We will tell you which one your house wants, and why, before you are asked to decide anything. What the two versions cost, and why they differ, is set out in pricing and planning.
Sprayed at the roofline
Foam applied to the underside of the deck follows every rafter, every valley and every awkward transition, including the ones a batt has to be forced around.
- Ducts come in from the heat The attic runs closer to indoor temperature, and the ductwork stops being the weakest link.
- The gaps go too Top plates, can lights, flue chases and the attic hatch are all lines on the scope.
- Depth is checked as we spray Verified with a gauge during application, while it is still within reach.

When attic work is the right first move
If more than one of these is true, the attic is almost certainly where your money should go first.
The upstairs runs hot
Rooms above the ceiling line run hot in the afternoon and stay hot into the evening.
The AC runs and runs
Long cycles in the afternoon usually mean the system is fighting heat coming in.
The insulation is original
Older blown-in settles, gets walked on, and gets moved by every trade who has been up there since.
On the written scope
What attic work covers
Air sealing happens in the same pass. It is how the job is done.
- Written scope before we start Area, product, depth and exclusions, priced.
- Roofline or attic floor Whichever the assessment says, with the reasoning written down.
- Top plate and penetration sealing Where wall cavities open into the attic.
- Can lights and flue chases Sealed appropriately for the fitting type.
- Attic hatch or pull-down Sealed and weatherstripped — a large hole most jobs ignore.
- Old material removed if needed Quoted separately so you can see what it costs.
- Depth verified as we go Recorded as the work goes.
- Clean-up and a walkthrough We show you what was done before we leave.
How it runs
One process, three stages
Most attics are a single day on site.
-
1
Inspect
Someone comes out and walks it with you. Attic, crawl space, roofline, ducts — anywhere air is moving through the envelope.
-
2
Scope
What we are spraying, where, to what depth, which surfaces stay as they are, and what it costs. In writing, before anything is ordered.
-
3
Install and verify
Masking, floor protection, ventilation and a clear route in and out. Depth is verified as we go, gauge in hand. We clean up, walk it with you, and leave the scope sheet behind.

Questions
Asked about this service
It depends on what is up there. If it is dry, clean and undisturbed, some jobs go over the top. If it is settled, wet, mouse-damaged or in the way of air sealing, it comes out — and we quote that separately so you can see the cost on its own.
Sealing the roofline means closing the vents on purpose, because the attic is now inside the envelope. That is a real change to how the house works, which is why we walk it with you before we price it.
Yes. Sealing the roofline usually makes it a better place to store things, because it now runs close to indoor temperature. Decking and walkboards are worth discussing while we are up there.
Ask your roofer before you commit, and get their answer in writing. Some manufacturers have conditions about unvented assemblies, and it is a much easier conversation to have before the work than after.
The visit is free. Someone comes out, looks at the building and gives you a written scope and a price, and the decision stays yours.
We work across 48 cities in the eight-county Houston–Galveston area — Harris, Fort Bend, Montgomery, Brazoria, Galveston, Chambers, Liberty and Waller — plus a set of extended project markets beyond it. If you are near the edge of that, call and ask.
