A hot upstairs or drafty attic
If the upstairs bakes or the room over the garage never catches up, the attic above it is usually thin, settled or leaking air, and that's where we start looking.

Insulation work Modesto homeowners call about most
Most calls start with a room that won't stay comfortable, and the fix usually sits in one of two places, over your ceiling or under your floor.
Cold floors over a crawl space
When the floors stay cold, the crawl space underneath usually has sagging insulation or bare ground, and we check for moisture there before we insulate or lay a vapor barrier.
Discuss your projectHow we work on your attic or crawl space
Problems fixed before we insulate
A wet spot, old wiring or a blocked eave vent only gets worse under new insulation, so we find it and deal with it before fresh material goes in.
Fuel-burning appliances checked before sealing
We seal the leaks before insulating, and we check what burns fuel in your house, like a furnace or water heater, before making it tighter, because those need air to work right.
Permits handled with your city or county
When a job needs a permit, we pull it with the city or county office that covers your address and set up the inspection before anything gets covered, so you don't chase it.
Insulation contractor services in Modesto, CA
TempGuard Modesto Spray Foam Insulation is an insulation contractor in Modesto, CA, with 16 services covering attics, walls, crawl spaces and commercial buildings. What moves the price is how many inches are already up there, whether old material has to come out first, how much air sealing the house needs and whether foam or loose fill fits it. The schedule turns on that same cleanup and sealing, plus any permit inspection and, with foam, the wait before you can go back inside. Your estimate comes after I've seen the house, so the figure fits your job and not a guess.
Spray foam insulation
Spray foam goes on as a liquid, expands into the gaps and seals air while it insulates. Everyone, kids and pets included, stays out while it's sprayed and until re-entry time, when you can come back.
Attic insulation
For a high power bill or an upstairs that won't cool off, we measure how many inches are already up there, keep the eave vents clear so the attic can breathe and bring coverage even out to the edges.
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's gone thin. It settles into corners and around framing that rolls and batts can't reach.
Home insulation
This is for the whole house when several rooms feel off. I look at the attic, walls and crawl space together and tell you which one is worth fixing first, and which can wait.
Insulation removal
Old insulation comes out when it's been soaked or packed with droppings, so the new layer starts on a clean floor. We vacuum it out, bag it and haul it off, then check the framing it was hiding.
Crawl space insulation
Insulation under the floor holds heat in the rooms above, but only if it stays in place. We fasten it up between the floor joists and deal with any wet spots down there first so it doesn't soak and sag.
Wall insulation
Older houses often have empty or half-filled outside walls, which is why a room can feel off right next to them. We fill closed walls through small holes, or insulate open walls during a remodel.
Air sealing services
Air sealing closes the gaps where air leaks in and out of your house, around pipes, wiring, can lights and the attic hatch. Skip it and new insulation spends its life fighting a draft.
Basement insulation
Basements are less common around Modesto, but where a house has one, we insulate the walls and the rim joist, the board on top of the foundation, so the room downstairs stops feeling like a cellar.
Closed-cell foam insulation
Closed-cell foam is the dense kind that also blocks moisture, so it suits rim joists, crawl space walls and places that get damp. It costs more than open-cell, and I'll tell you when the extra isn't worth it.
Open-cell foam insulation
Open-cell foam is softer and lighter, and it's a common pick under a roof deck when the ductwork runs through the attic. It seals air and quiets noise, but it doesn't stop moisture the way closed-cell does.
Commercial insulation
Landlords and business owners call us for offices, shops and rentals. The order is the same as on a house, find what's wrong, seal, then insulate, and we plan the work around the people using the building.
Crawl space vapor barrier
A vapor barrier is heavy plastic laid over the dirt in your crawl space to keep ground moisture from rising into the floor and insulation. We seal the seams and run it up the walls so it doesn't shift.
Vapor barrier installation
In walls, ceilings and over slabs, a vapor barrier keeps moisture out of the insulation. Not every wall wants one, so I check how yours is built before we add plastic to it.
Attic air sealing
This is the attic part of air sealing, done from above before the insulation goes back down. We foam and caulk around the hatch, plumbing and wiring holes so attic air stops leaking into the rooms below.
Retrofit insulation
Retrofit insulation goes into a house that's already finished and lived in, often an older one built with little or none. We get in through the attic or small holes in the walls, so the drywall stays put.
Who looks at your house and does the work
I left an office job for this work, learned the trade on an insulation crew here in Modesto and started TempGuard in 2013. The attics run hotter than the office did, but nobody calls a meeting in one.
We're licensed and insured, and we're known for looking hard at a house before we sell it anything. Satisfaction guaranteed. You can read more about our crew and how we work.
I write the estimate myself
I come out, look at the job and write the estimate, then our installers do the work and I go over it with you at the end, so what you agreed to gets done.
Based in Modesto, working three counties
Modesto is home base, and we work in the cities around it in Stanislaus County and over into San Joaquin and Merced counties, so call if you're not sure we reach you.
A straight answer on what's worth it
If topping up your attic won't change much, I'll tell you, because I'd rather lose the sale than sell you insulation you don't need.

Fill in the form or use our contact page, and we'll get back to you within one business day. Then I come out, look at the job and write your free estimate, with no pressure and no obligation.
Tell us which rooms bother you
Mention the hot upstairs, the cold floors or the room over the garage, because where you feel it tells me whether to start in the attic or the crawl space.
Share the year it was built
Older houses often have little in the walls and old wiring in the attic, so knowing the age helps me plan what to check before we cover anything.
Call any day of the week
We're open 7 AM to 11 PM, Monday through Sunday, so you can call after work or on a weekend instead of waiting for Monday.
Examples of insulation materials and layouts
These examples show spray foam, blown-in fill, crawl space barriers and sealed attics, so you can point to what you're picturing when we talk.
Insulation questions Modesto homeowners ask us
Here are straight answers to what people ask first about cost, time in the attic, leaving the house and permits in Modesto.
How much does attic insulation cost in Modesto?
It depends on your attic, so I give you a number after I've looked at it, not over the phone. Two attics the same size can price very differently when one needs old insulation pulled out or a lot of gaps sealed first. The estimate is free and I write it on site.
How long will the insulation crew be in my attic?
It depends mostly on whether old insulation has to come out first and how much sealing the attic needs, so I'll tell you what to expect once I've been up there. A plain top-up of blown-in insulation goes quicker than a job that starts with removal or foam.
Do we have to leave the house during spray foam insulation?
Yes, with spray foam everyone, kids and pets included, stays out while it goes on and until re-entry time, when you can come back in. With blown-in insulation most families stay home, since the work happens up in the attic. I'll go over the timing for your house at the estimate.
Is spray foam worth it, or should I get blown-in insulation?
For most attics, sealing the gaps and topping up with blown-in insulation is the better buy. Spray foam costs more because it seals air while it insulates, and it starts to earn that when your ductwork runs through the attic. I'll tell you which one fits after I've seen yours.
Should old insulation be removed before adding new?
Only when it's wet, moldy or full of droppings, because new material on top of that keeps the problem in your attic. Dry, clean insulation that's just thin can usually stay, and we add to it. I check which one you've got before I write anything up.
Who handles building permits for insulation work in Modesto?
We do, when your job needs one, and we pull it with whichever city or county office has your address. Inside Modesto that's the City of Modesto's Building and Development Services team, which helps residents with building permits. If you'd like to ask whether your job needs one, that's the place to start.
When does the inspection happen on an insulation job in Modesto?
On a permitted job, the inspection happens before the work gets covered up, because the city checks it against the building codes while it's still visible. We request and set up that inspection ourselves, so you don't have to. When the work is done, I go over it with you before we leave.
