The work
What whole-home spray foam actually means
Most Houston houses have an air problem. Conditioned air leaves through the top of the building and hot, wet outside air is pulled in behind it — through the attic hatch, the can lights, the top plates, the rim joist, and every penetration a plumber or electrician ever made.
Spray foam is the only common insulation that seals and insulates in the same pass. It is applied as a liquid, expands into the cavity, and takes the shape of whatever it is sprayed against, including the gaps a batt has to be cut around.
Whole-home work usually means the attic roofline, the exterior walls where they are open, the rim joist, and the garage ceiling under living space. Which of those your house actually needs is what the assessment is for, and the zone-by-zone guide sets out how each behaves.
Sealed at the gaps batts leave behind
By the time the trades have finished, a wall cavity is an irregular shape. Wiring, plumbing stub-outs, bracing and blocking all break up the bay, and a batt cut around them leaves a gap that disappears from view once the drywall is on.
- Every cavity in the bay Foam expands into the corner behind a pipe, which is exactly where a cut batt leaves a void.
- Air sealing and insulation together One material, one pass, with the sealing built into it.
- It stays where it is sprayed Foam is adhered to the substrate, so it holds its position in the cavity for the life of the wall.
Is this you?
Who this suits
Whole-home work is worth it in some houses and overkill in others. These are the ones where it usually pays.
Houses with a hot upstairs
A second floor that runs hot in July is almost always an attic and duct problem.
Attic and air sealingHouses that feel humid indoors
If the AC runs and the house still feels damp, outside air is getting in faster than the system can dry it.
Crawl space and rim joistHouses being renovated
Open walls are the cheapest they will ever be to insulate properly. Foam goes in before the drywall does.
New constructionOn the written scope
What a residential scope covers
Every line below appears on the written scope with a location and a depth, naming the assembly, the product and the depth.
- A written scope Areas, product, depth, exclusions and price, before anything is ordered.
- Attic roofline or attic floor Which one depends on where your ductwork runs. We will explain the difference on site.
- Exterior walls where open Standard on renovations and new builds. Requires the drywall to come off on a finished wall.
- Rim joist and band joist A small area that leaks disproportionately, and one of the most common misses.
- Penetrations and top plates Plumbing, wiring, flue chases and the attic hatch.
- Protection and clean-up Masking, floor protection and removal of everything we brought in.
- Depth verified as we go Checked with a gauge during application.
- One crew, start to finish The people who quoted it are the people who spray it.
Straight comparison
Open-cell or closed-cell
Both are spray foam and both seal air. They behave differently, and the right one depends on where it is going.
| What changes | Open-cell | Closed-cell |
|---|---|---|
| Where it is usually used | Attic rooflines, interior walls, sound work | Rim joists, crawl spaces, metal buildings, anywhere water contact is possible |
| Density | Light and soft | Dense and rigid |
| Water | Absorbs and releases water, so a roof leak still shows itself | Sheds bulk water |
| Sound | Better at damping airborne sound | Weaker at sound than open-cell |
| Adds rigidity | No | Yes, it stiffens the assembly it is bonded to |
| Cost per square foot | Lower | Higher |

How it runs
One process, three stages
You know the price before anything is ordered.
-
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
Most households stay in the house, and you do need to be out of the working area while it is sprayed and while it cures. We will tell you the re-entry time for the product we are using before the day, so you can plan around it.
Foam expands as it cures, so it needs an open cavity. Finished walls are a job for dense-pack blown-in, which is a service we also run.
It removes the main way humid outside air gets in, which is usually the biggest part of it. If the house also has a ventilation or drainage problem, that has to be dealt with too — we will tell you on site if we think that is what is going on.
Most houses are one or two days on site. Bigger or more complicated rooflines can run longer, and the written scope will say which yours is.
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.
