Spray foam insulation
Foam sprayed onto the underside of the roof deck seals air and insulates at the same time, which earns its higher cost when your ductwork runs through a hot attic.
Insulation Contractor in Chino, CA - Cooler Upstairs Rooms Through Hot Summers
Truetemp Corona Spray Foam Insulation insulates and air seals attics, walls and crawl spaces in Chino, CA. We track down why one room runs hot, then fix that cause with blown-in, spray foam or sealing work.
What insulation work looks like in Chino
Chino summers are long and hot. In a normal year about 99 days reach 90 degrees and 23 of them go past 100, while only about 11 nights drop to freezing, so most of the calls we get here are about heat, not cold. That usually sounds like an upstairs bedroom that never cools off, or the room over the garage that's fine in April and miserable by July. We're based in Corona, and we hear the same complaint from here out to Temescal Valley.
The price moves with the size of the attic, how easy it is to get into, how many inches are already up there and whether any of it has to come out first. The schedule turns mostly on removal and on a permit, if the city wants one. I look at all of that in person and write up the estimate, so you get a number for your house instead of a guess. With houses here running from older single-story ranches to newer two-stories, the attic decides most of the job.
I do the looking myself
I come out, climb into your attic with a flashlight and write up the estimate, so what we recommend matches what's actually up there and not what's easiest to sell.
We clear the eave vents first
Buried vents stop the attic from breathing and moisture ends up in the framing, so we keep them open before any new insulation goes in.
A lead installer runs each job
Our installers do the work with one lead installer in charge, so one person knows the plan and can answer your questions while the crew is in the attic.
Insulation services we offer in Chino
Attic insulation
We check how many inches are already up there, keep the eave vents clear, then bring the edges up to match the middle, where coverage usually runs thin.
Blown-in insulation
Blown-in, loose fill blown through a hose, tops up an attic quickly and settles around wiring and framing. We seal the gaps underneath first so it isn't fighting a draft.
Home insulation
When several rooms feel off, I go through the whole house, attic to floor, and look for the pattern before recommending anything, so you fix the cause once.
Insulation removal
If the old insulation was soaked or full of droppings, we take it out before anything new goes in, because fresh material laid on top just keeps the problem.
Crawl space insulation
On houses built over a crawl space, cold floors on winter mornings usually trace back to bare floor framing. We check the crawl for moisture, then insulate between the joists.
Wall insulation
Older walls are often empty or half full, which shows up as a room that soaks up heat all afternoon. We fill them through small holes and patch them afterward.
Air sealing services
Air sealing, closing gaps before insulating, goes after the holes around can lights, pipes and the attic hatch. It's often the smaller fix that makes the insulation you have work.
Basement insulation
For houses with a basement or a below-grade room, we insulate the walls with materials that can handle the damp that comes through concrete, so the insulation stays dry.
Closed-cell foam insulation
Closed-cell foam, a dense foam that blocks moisture, suits crawl spaces and below-grade walls where damp is part of the problem. It costs more, so we use it where it matters.
Open-cell foam insulation
Open-cell foam is lighter and softer, a good fit for sealing a roof deck over ductwork. It also dulls sound between rooms, which helps over a noisy garage.
Commercial insulation
We insulate rentals and small commercial buildings for landlords and building owners, working around tenants and business hours so the space keeps running while we're up top.
Crawl space vapor barrier
A heavy plastic sheet over the dirt in a crawl space keeps ground moisture out of the framing and insulation above. We seal its seams and edges so it stays put.
Vapor barrier installation
We add vapor barriers where moisture would otherwise work into insulation, and we're careful about which side they go on, because the wrong side traps damp instead of stopping it.
Attic air sealing
Before insulation goes in, we seal the attic floor around can lights, plumbing stacks, wiring holes and the hatch, so cooled air from your house stops leaking up.
Retrofit insulation
Retrofit work adds insulation to a finished house without tearing it open, through the attic, small holes in the walls or the crawl space, depending on where the gap is.

Questions about insulation work in Chino
Here's what Chino homeowners ask us most about permits, licenses and which fix fits their attic, answered the way I'd answer on site.
Do I need a permit for attic insulation in Chino?
Ask the city's Building Division, because Chino requires a permit for all work except what the state codes exempt, and its own examples of exempt work are things like painting, carpet and tile, not insulation. We check with the Building Division for each job, and if a permit is needed, we handle the application and meet the inspector.
How long is a building permit good for in Chino?
A Chino building permit expires 180 days after it's issued, or 180 days after work stops, according to the Building Division's guidance. The building official can grant one 180-day extension at no cost if a letter with the reason arrives before it expires. When a permit is part of the job, we plan the work around that clock.
Does a contractor from outside Chino need a Chino business license?
Yes. The city requires anyone doing business in Chino to hold a city business license, and that includes contractors and service companies from out of town. It's a fair question to ask anyone you're thinking of hiring, us included, since we're based in Corona.
When does an insulation contractor need a California license?
Under the Contractors State License Board's rules, anyone who alters a building in California needs its license when the job needs a building permit, uses any additional workers, or totals $1,000 or more in labor and materials. A crew job meets that test on its own. We're fully licensed and insured, and you can ask about it when I come out.
Should I get spray foam or more blown-in insulation in my Chino attic?
Sealing the gaps and topping up the blown-in usually wins on cost. Foam costs more but seals air while it insulates, so it earns its price when your ductwork runs through the attic. I'll look at what's up there and how many inches you already have before I recommend either.
