Spray foam insulation
Spray foam fits rooms over the garage and attics where the ductwork runs, because it insulates and seals air in one pass, though it costs more than loose fill.
Professional Chico Spray Foam Insulation is an insulation contractor based in Chico, CA, working on Oroville homes. We insulate and air seal attics, crawl spaces and walls, and pull out damaged old insulation before new goes in.

Professional Chico Spray Foam Insulation insulates and air seals Oroville homes from the attic down to the crawl space. That covers topping up blown-in, spray foam where it earns its cost, wall insulation, vapor barriers and pulling out old insulation that's done. We drive over from Chico for these jobs and do them the same careful way.
Most Oroville calls start with a hot upstairs, cold floors, a drafty back room or the room over the garage. Those usually trace back to the attic or the crawl space, so that's where I start, checking how many inches are already up there, whether the gaps around lights and pipes are open, and whether the vents along the eaves can still breathe.
Under the house, we look for floor insulation that has sagged or fallen and at what's covering the dirt, since cold floors and a damp smell often start there. We do the same work nearby in Paradise and Thermalito, so if family or neighbors there have the same complaints, the visit works the same way.

Most Oroville calls about a hot upstairs end up here. We measure what's already in the attic, seal the gaps, then bring the depth up evenly, edges included.
Blown-in, loose fill sent through a hose, is usually the cheaper way to top up an attic once the gaps around lights, pipes and the hatch are sealed.
When several rooms feel off, I look at the attic, walls and crawl space together, so you fix the biggest leak first instead of guessing one room at a time.
If old insulation is wet from a past leak or full of droppings, we bag it and pull it out, because new material laid on top just keeps the problem.
Cold floors usually start below. We find the sagging or missing pieces under the house and refit the insulation so it stays tight against the floor above.
Exterior walls in older houses are often empty or thin. Where the wall allows it, we fill them through small openings and close those up when we're done.
Air sealing, closing the gaps before insulating, is often the cheapest fix for a drafty house, because air slipping through cracks carries your heat and cooling with it.
Where a house has a basement or a below-grade room, we insulate the walls and the rim, where the floor framing sits on the foundation, to cut drafts.
Closed-cell foam, a dense foam that blocks moisture, suits spots that stay damp or need a tight seal in a thin space, like a crawl space rim.
Open-cell foam is softer and costs less than closed-cell, and it works well under a roof deck or in interior walls where moisture isn't the worry.
For shops and offices in Oroville, I walk the building first and plan the work around your hours, so the crew stays out of your customers' way.
A vapor barrier over crawl space dirt keeps ground moisture from climbing into the floor insulation and framing, so we overlap the seams and run it up the walls.
In walls and ceilings, a vapor barrier has to go on the side that keeps damp air out of the insulation, so I check how your house is built before we install.
Before an attic gets more insulation, we seal around can lights, pipes, wires and the hatch, because insulation laid over open gaps ends up fighting a draft.
Retrofit work adds insulation to a finished Oroville house without tearing it apart, working through the attic, the crawl space or small openings in the walls.
We reply to calls and form messages within one business day to set a time. I come out to your Oroville house myself, look at the attic or crawl space, and write the estimate on site. It's free and obligation-free, so you can take it and think it over.
(530) 399-1513Who issues a permit depends on which side of the city line your house is on. Inside city limits, the City of Oroville building department handles it, and outside them, Butte County offers building services for unincorporated communities. We work on both sides, including nearby Palermo. If your job needs a permit, we handle the application and inspection with the right office and tell you which one it is, and that step can set the start date.
The city requires a current business license for anyone operating a business within city limits, which is worth asking any contractor about before work starts. We're licensed and insured. Past the paperwork, the schedule turns on what I find, because old insulation that has to come out, or a roof or wiring problem another trade should fix, comes before anything new goes in.
The price moves with the size of the attic or crawl space, how many inches are already there, whether the old material is clean enough to stay, how much sealing the gaps need and whether you pick foam or loose fill. Foam costs more and seals while it insulates, but sealing the gaps and topping up blown-in usually wins unless your ductwork runs through the attic. The free estimate gives you your own number.
I grew up on a farm where you fixed things right the first time, learned insulation on other contractors' crews, and started this business in Chico in 2020. I'm the one who comes out to look at your job and write the estimate. Our crew lead and installers do the work, and I check it before we're done, including that the edges got the same depth as the middle and the eave vents are still open.
If I find something that needs another trade first, I'll tell you and wait rather than insulate over it, because covering up a problem only makes it more expensive later. Satisfaction guaranteed on every job. When you're ready, call (530) 399-1513 or use the contact form to set up a visit.
A few things come up again and again on Oroville jobs, from the weather the attic has to handle to the work that should happen before we start.
Oroville gets four distinct seasons, so an attic here has to slow heat coming in during summer and heat leaving in winter. That's why we seal the gaps around lights, pipes and the hatch before any insulation goes in, because loose fill sitting over open gaps still lets air move both ways, and the house never quite feels settled in either season.
If a new roof, furnace or duct replacement is on your list this year, it usually makes sense to finish that before we insulate. Otherwise somebody ends up digging through fresh insulation to reach the roof deck or a duct, and it rarely gets put back the way it was. I'll tell you the order I'd do it in, even if it means we wait.
The city says work done without a permit is illegal and can cause serious trouble with fire and homeowner's insurance, or when you sell your home. If we spot signs of unpermitted work in the attic or crawl space, like spliced wiring or a vent line that wasn't run right, I'll point it out before we cover it, so you can sort it out first.
Many Oroville attics we open have insulation from more than one era stacked together, some settled flat, some stained from an old leak, some full of droppings. Measuring the inches is the easy part. Checking whether that material is dry and clean decides whether we top it up or pull it out, and that one call shapes the whole job.
The city's own list doesn't settle it, because the work it names for building permits, like roofs, furnaces, water heaters and windows, doesn't include insulation. If you're inside city limits, check the city's permit page or ask the building department. If your job does need one, we take care of it as described above.
The city says projects that go to plan review take 10 to 15 working days, depending on the type of project, while simpler installs like reroofs and new heating and cooling units are available over the counter. Room additions are the city's example of plan review work. If your insulation job needs a permit, we plan the start date around that wait.
We do, since we're based in Chico and work in the cities around it, and if you don't see yours listed, call and ask. For permits outside city limits, it's Butte County that offers building services to unincorporated communities, as we covered above, and we deal with that office the same way.
There's no fair number until I've been in your attic, so I write a free estimate on site after measuring. The biggest swing is usually whether the old insulation can stay or has to come out first, and sealing the gaps and topping up with loose fill is often the cheaper route that still does the job.
A top-up over clean insulation is the quickest job we do, and it takes longer when old material has to come out or the gaps need a lot of sealing. I'll walk you through the plan at the estimate, including which rooms we pass through and how we cover the floors on the way to the hatch.
Yes, you, the kids and the pets stay out until the re-entry time, when the foam maker says it's safe to come back, has passed. Blown-in insulation and air sealing usually don't need you out of the house. We tell you the re-entry time before we start, so you can plan the day around it.
Clear a path to the attic hatch and move whatever is stored right under it. Boxes kept up in the attic usually need to come down before we blow in new insulation, and if you have pets, tell us so we can keep the right doors shut while the crew is going in and out.
Call (530) 399-1513 or send the contact form with the room that's hot, cold or drafty, so I can head straight to the right part of the attic or crawl space when I come out.
