Spray foam insulation
Spray foam fills and seals odd spaces like rooflines and the room over the garage in one pass. It costs more than loose fill, so I'll look first and tell you whether your house actually needs it.
Insulation contractor in Modesto, CA - comfortable rooms, done in the right order
TempGuard Modesto Spray Foam Insulation is an insulation contractor based in Modesto, CA. We seal and insulate attics, walls and crawl spaces in houses across the city, and we take out old insulation that's past saving.
What we find in Modesto attics and crawl spaces
Modesto is home base. I learned the trade on an insulation crew here after leaving an office job, and the attics are hotter but at least nobody holds meetings in them. Most of our calls are about a room that won't stay comfortable, usually upstairs or over the garage, plus some from landlords and business owners. We work Ceres, Salida and Riverbank the same way.
In older houses we usually find a few inches of old fill packed flat, open gaps around can lights and pipes, and now and then droppings or a water stain under it all. Newer houses tend to have more up there, but it's thin at the edges and the ductwork often runs through the attic.
The price moves with how much is already up there and what shape it's in, how many gaps need sealing, whether old material has to come out first and whether foam is worth it for your ducts. The schedule turns on the same things, plus a permit and inspection when a job needs one. Your own number comes from the estimate, which I write after looking at the house myself.
Wet spots get fixed first
If there's a leak stain, a damp patch or old wiring up there, it gets fixed before insulation goes over it, because burying a problem just hides it until it's worse.
Fuel burners get checked
Before we make a house tighter, we check the water heater, furnace and anything else that burns gas, so they still get the air they need once the gaps are closed.
A straight answer on value
I'd rather tell you a job isn't worth the money than sell you insulation you don't need, so sometimes the estimate says to seal a few gaps and stop there.
Insulation services we do in Modesto
Attic insulation
We measure what's already up there, seal the gaps, then bring the depth up evenly across the whole attic, full out at the edges where it's usually thinnest instead of piled up in the middle.
Blown-in insulation
Blown-in insulation is loose fill blown through a hose, and it's the usual way to top up an attic that already has some. We keep the eave vents clear so the attic can still breathe.
Home insulation
If the whole house is drafty or one room runs hotter than the rest, I check the attic, walls and crawl space, then tell you which part is costing you most and what can wait.
Insulation removal
Insulation that's been soaked, matted down or filled with droppings has to come out, because new material on top just hides it. We vacuum it out and clean up before anything new goes in.
Crawl space insulation
Cold floors usually trace back to the crawl space, where old batts sag or drop out of the joists. We check for damp and pests first, then insulate under the floor so it stays put.
Wall insulation
Some older Modesto houses have little or nothing in the walls, and you feel it most in rooms with a lot of outside wall. We fill closed walls or insulate open ones before the drywall goes up.
Air sealing services
Air sealing means closing the gaps where air slips in and out, around windows, outlets, ducts and plumbing runs. On a drafty house it's often the cheapest fix, so it's usually where we start.
Basement insulation
When your house or building has a basement, we insulate its walls and the rim joist, the wood band sitting on top of the foundation, where a lot of outside air usually sneaks in.
Closed-cell foam insulation
Closed-cell foam is dense foam that also blocks moisture, so it suits crawl spaces, rim joists and spots that stay damp. It costs the most, so we use it where that moisture block earns its keep.
Open-cell foam insulation
Open-cell foam is lighter and softer than closed-cell and fills odd shapes well, so it works for rooflines and walls. It also quiets noise, which helps in a bedroom over the garage.
Commercial insulation
We insulate and seal offices, shops and rental buildings for business owners and landlords around Modesto. I walk the building first, and we plan the work around your hours and your tenants.
Crawl space vapor barrier
A vapor barrier here is a heavy plastic sheet laid over the dirt in your crawl space to keep ground moisture out of the floor framing. We overlap and tape the seams so it stays in place.
Vapor barrier installation
We also put vapor barriers on walls and ceilings where moisture needs stopping before it reaches the framing. On some walls a barrier would trap water instead, and I'll tell you when that's the case.
Attic air sealing
Before any insulation goes up, we seal the attic floor around can lights, plumbing, wiring holes and the hatch. Skip that and the new insulation ends up fighting a steady draft.
Retrofit insulation
Retrofit work adds insulation to a house that's already finished, without tearing it apart. We go in through the attic, the crawl space or small holes in the walls, and patch whatever we open.

What I measure on the visit
I check how many inches are already up there, what shape it's in, where air gets through and how old the house is, because those decide what the job needs.

Questions about insulation work in Modesto
Straight answers on permits, inspections, spray foam and whether you'll need to leave the house while we work.
Who handles building permits for insulation work in Modesto?
The City of Modesto's Building and Development Services team helps residents with building permits, and they're the ones to ask whether your job needs one. When it does, we pull the permit with the city, or with the county if your address falls there. We're licensed and insured, so the paperwork side is on us.
When does the inspection happen on a permitted insulation job in Modesto?
Before the work gets covered. The city inspects permitted work to check it was done to the building and safety codes, and the inspection has to be requested through its online permits portal before anything is covered or built over. We set that up ourselves, so the inspector sees the work while it's still open.
Do we have to leave the house during spray foam insulation?
For spray foam, yes, you, the kids and the pets stay out until the re-entry time is up, which is the wait before it's safe to come back inside. I'll tell you that wait before we start so you can plan around it. Blown-in work and air sealing usually let you stay home.
Is spray foam worth it over blown-in insulation for a Modesto house?
Usually not, unless your ductwork runs through the attic. Foam costs more because it seals air while it insulates, but sealing the gaps and topping up loose fill does the job for less in most houses we see. With ducts up there, foam keeps them inside the sealed part of the house, and that's when I'd pick it.
