Spray foam insulation
We spray foam where sealing and insulating need to happen in one pass, like a room over the garage or a detached shop. It goes on wet and swells into the cracks that let dust and outside air in.
Insulation contractor in Oak Hills, CA - cooler summers, warmer winter rooms
R&S Hesperia Insulation Company is an insulation contractor based in Hesperia, CA, working in Oak Hills. We seal the gaps, pull out ruined insulation and add what your attic, walls and crawl space need for hot summers and freezing nights.
Insulating Oak Hills homes for heat and frost
Oak Hills sits right next to Hesperia, where we're based, and it's dry country in the rain shadow of the San Bernardino Mountains. Summers run hot and dry, and winters can drop below freezing and now and then bring snow, so the same attic has to keep heat out in July and hold it in on a January night. We do the same work in Spring Valley Lake and Phelan, but in Oak Hills I see more big lots, rooms over the garage and detached shops.
Oak Hills is unincorporated, and San Bernardino County is the local government, so building inspection and planning go through the county instead of a city hall.
What moves the price is the size of the attic, how many inches are already up there and whether the old insulation has to come out before new goes in. The schedule mostly turns on that removal, and on foam's wait before you can come back inside. I come out myself and look at the space before I put anything on paper.
Built for both seasons
Insulation here has to slow summer heat coming down through the ceiling and hold furnace heat on freezing nights, so thin spots at the edges of an attic show up in both seasons.
What's up there gets checked
If the old insulation is soaked, packed flat or full of droppings, we pull it out first, because new insulation laid over a bad layer just keeps the problem in your attic.
Sometimes you don't need more
If you already have plenty and the draft comes from the hatch or around recessed lights, I'll tell you so, because sealing those gaps can be all the job takes.
What we insulate and seal in Oak Hills
Attic insulation
Most Oak Hills calls start in the attic, where the summer sun beats on the roof all afternoon. We measure the inches already up there and build it to full depth out to the edges, where coverage usually runs thin.
Blown-in insulation
Blown-in insulation is loose fill we blow through a hose, and it's how we top up an attic that's settled thin over the years. It fills around wires and framing, and we keep it clear of the vents at the eaves.
Home insulation
When a house runs hot upstairs and cold underfoot, I look at the attic, walls and floors together and tell you which one is actually costing you, so you don't pay for work that can wait.
Insulation removal
Insulation that's been soaked by a roof leak or packed with rodent droppings comes out before anything new goes in. We bag it, clean the attic floor and haul it away, so the problem leaves with it.
Crawl space insulation
If your floors feel cold on freezing mornings, the crawl space is usually why. We insulate under the floor and seal around pipes and openings so the cold air down there stays down there.
Wall insulation
Older walls built empty or with thin batts can be filled without tearing them open. We check what's inside first, through an outlet box or a small hole, before we put a number on it.
Air sealing services
Air sealing means closing the gaps before any insulation goes in. Around the house we seal at doors, outlets, plumbing and the spot where the walls meet the foundation, so the insulation isn't fighting a draft.
Basement insulation
Basements aren't common in the high desert, but when a house has one, we insulate the walls and the framing that sits on the foundation so the space stops pulling heat from the rooms above.
Closed-cell foam insulation
Closed-cell foam is a dense foam that blocks moisture as well as air, so we use it where damp is a worry, like a crawl space wall or a metal shop building that sweats in a cold snap.
Open-cell foam insulation
Open-cell foam is softer and lighter than closed-cell, and it fills odd roof lines and wall cavities without leaving gaps. We use it indoors where moisture isn't the issue, and it quiets a room too.
Commercial insulation
Shop and building owners call us when a space won't hold its temperature through a hot afternoon or a cold night. We look at the roof, walls and big doors and insulate what's actually letting it slip.
Crawl space vapor barrier
A vapor barrier is a heavy sheet laid over the dirt in a crawl space to keep ground moisture out of the floor framing. Even in dry country we overlap and tape the seams and run it partway up the walls.
Vapor barrier installation
We put vapor barriers in walls, floors and ceilings where warm indoor air would otherwise meet a cold surface on a freezing night and leave damp behind in the framing.
Attic air sealing
Before we add a single inch, we seal the holes cut through the ceiling for lights, fans, pipes and the hatch. It's the step that gets skipped most, and it's the one you feel in a drafty room.
Retrofit insulation
Retrofit work means adding insulation to a house that's already built and lived in, without a remodel. We work through the attic, the crawl space or small holes in the walls, and patch what we open.

Insulation questions from Oak Hills homeowners
These are the questions Oak Hills homeowners ask most before we start, about permits, licenses, foam and whether you have to leave the house.
Do I need a permit to insulate my attic in Oak Hills, CA?
Ask the county before work starts, because its permit list names jobs like re-roofing, additions and alterations, and says other work may still need one. The county's Building and Safety office issues permits for unincorporated parcels and answers desert-area questions at (760) 995-8140. When a job calls for a permit, we handle the paperwork and set up the inspections.
Does an insulation contractor in Oak Hills need a California license?
Yes, if the job needs a building permit, brings in other workers or comes to $1,000 or more in labor and materials combined. That's the rule from the California Contractors State License Board, and the board also says a contractor has to hold the license before bidding on the work. We're licensed and fully insured.
Is spray foam worth the extra cost in an Oak Hills attic?
Usually not, unless your ductwork runs through the attic. Foam costs more because it seals air and insulates in one step, but sealing the gaps and topping up blown-in insulation usually gets a house there for less. If your ducts live up there, foam under the roof brings them inside the insulated space, and that's where I'd spend the money.
Do we have to leave the house while you insulate?
For blown-in insulation and air sealing, usually not, because the work stays up in the attic and we cover the path from your door to the hatch. Spray foam is different. You, the kids and the pets head out, and the foam maker's re-entry time, how long before anyone can come back inside, decides when you return.
