Spray foam insulation
We spray it where ducts run through a hot attic or a space is too broken up to seal by hand, since it fills the gaps and insulates in the same pass.
Insulation contractor in Hesperia, CA - Sealed first, then insulated
R&S Hesperia Insulation Company is an insulation contractor based in Hesperia, CA. We seal the gaps, clear out bad material and insulate attics, walls, crawl spaces and shops, so hot rooms and drafty floors settle down.
What we find in Hesperia attics and crawl spaces
I started this business in Hesperia in 2013, and most calls here come from the same few things. A hot back bedroom, a room over the garage that won't cool, cold floors in winter or a power bill that keeps climbing. In a lot of these houses the ductwork runs through the attic, so a thin, leaky attic heats the air before it ever reaches you, and the wind pushes dust through every gap around the hatch, pipes and can lights. The city rates termite exposure here as very heavy, so I look over the wood in the attic and crawl space before we cover any of it. We do the same work in Victorville, Apple Valley and Oak Hills.
The price moves with how many inches are already up there, whether old insulation has to come out first, how many gaps need sealing and which material fits your house. Foam costs more and seals air while it insulates, but sealing the gaps and topping up with blown-in, loose fill we blow in through a hose, usually wins unless your ducts are up there. The schedule turns on removal, any permit and inspection, and the re-entry time if we use foam. I look at the space myself before I write anything down, so your estimate is for your house.
Hesperia's Building & Safety Division enforces the building codes here and issues the permits, so it's the office to ask about your job. If you're building new in one of the very high fire hazard zones the county fire district has widened across Hesperia, the wildfire building rules apply to that permit application too.
Prep before any insulation
We seal gaps around lights, pipes and the hatch and pull out wet or dropping-filled insulation first, because new material laid over a leak or a mess just hides it.
Licensed for the size of job
State rules let someone without a contractor license take only jobs under $1,000 that need no permit, working alone. We're licensed and fully insured, and the city requires a business license too.
Permits and inspections handled
When a job calls for a permit, we do the paperwork with the city or county office and set up the inspections, so you aren't left chasing it.
Insulation work we do around Hesperia
Attic insulation
Most Hesperia calls start up here. We measure the inches already in place, seal the gaps, keep the eave vents clear and bring the edges up as deep as the middle.
Blown-in insulation
Loose fill blown through a hose tops up thin or settled attics and closed walls. It's usually the sensible choice here, as long as the gaps underneath get sealed first.
Home insulation
A whole-house look at where the heat gets in, from the attic and walls to the floor over the crawl space and the room over the garage, so we fix the worst spot first.
Insulation removal
When old insulation is soaked, flattened or full of droppings, we bag it out and clean the space before anything new goes in, because topping it up keeps the smell and the problem.
Crawl space insulation
Cold floors over a crawl space usually mean bare joists or batts that have fallen down. We check the wood and any moisture first, then fit insulation that stays put.
Wall insulation
For older houses with empty or thin walls, we blow insulation in through small holes and patch them, so the rooms warm up without tearing out the drywall.
Air sealing services
We close the gaps around can lights, plumbing, wiring holes and the attic hatch before insulating, so dust and hot air stop pushing through and the insulation can do its job.
Basement insulation
Basements are rare up here, but where a house has one, we insulate the walls and rim joist so the space stays dry and holds its temperature through cold nights.
Closed-cell foam insulation
This dense foam blocks moisture as well as heat, so we use it on rim joists, metal buildings and spots that sweat, where open-cell or batts would soak up water.
Open-cell foam insulation
Softer and lighter than closed-cell, it seals and quiets interior walls and rooflines where moisture isn't a worry, and it fills odd framing well for less money.
Commercial insulation
For shops, garages and small buildings around Hesperia, we insulate walls and ceilings so the space holds its temperature, and we work around your hours and equipment where we can.
Crawl space vapor barrier
A heavy plastic sheet laid over the dirt and lapped up the stem walls keeps ground moisture away from the floor framing and the insulation above it.
Vapor barrier installation
We add a barrier where warm, moist air could reach a cold surface, like under floors or on shop walls, and we leave it out where it would trap water instead.
Attic air sealing
Before new insulation goes in, we seal the top plates, can lights, flue and duct gaps and the hatch from above, because loose fill won't stop a draft by itself.
Retrofit insulation
For houses you already live in, we add insulation to existing attics, walls and floors without a teardown, checking the old material and wiring first so nothing gets buried that shouldn't.

Hesperia insulation questions we hear
Here's what Hesperia homeowners ask most about permits, crew hours and getting back into the house after insulation work.
Do I need a permit to add insulation in Hesperia?
The city's permit list doesn't settle it, because it names work like new HVAC units, re-roofing over 25%, room additions and patio covers, not insulation by itself. Any permit has to be issued before work starts, so ask the city's Permit Center first. If your job does need one, we take care of it.
Who can pull a building permit in Hesperia?
Only the property owner, the owner's licensed contractor or an authorized agent can get one. It's issued once the plans are approved and fees are paid, and the approved plans and job card stay on site. Inspections are booked at each step with 24 hours' notice, and we set those up when we're your contractor.
What hours can insulation crews work in Hesperia?
Construction is allowed from 7 a.m. to 7 p.m., Monday through Saturday, with no work on Sundays or federal holidays. That covers repair work like ours, so our crew keeps to those hours even though we answer the phone seven days a week.
Do we have to leave the house while you insulate the attic?
Usually not for blown-in or batts, since the work stays in the attic and you can go about your day. Spray foam is different, because it comes with a re-entry time, the wait before people and pets come back inside, set by the foam maker. I'll go over it with you at the estimate so you can plan.
