Hot rooms upstairs
When the upstairs bedrooms stay hot into the night, the heat is usually coming down through the ceiling. Sealing the attic floor and topping up the fill slows it where it starts.

Adding insulation to a house that's already built
Retrofit insulation in Hesperia means adding insulation to a house that's already standing, usually blown-in insulation, loose fill blown through a hose, spread across the attic floor so the attic holds back more of the heat.
I started R&S Hesperia Insulation Company in 2013, and most of the calls we get are about a hot upstairs, the room over the garage or a power bill that keeps climbing. The price depends on how big the attic is, how old the house is, how many inches are already up there and what shape they're in, how many gaps need sealing, and whether old wiring or ruined insulation has to be dealt with first. Those same things set the schedule, along with any permit, and you get your own number after I've been up in the attic myself.
When a job calls for a permit, we handle the paperwork with the city or county office and set up the inspections.
Prep before any insulation
We seal the gaps and fix what's wrong up there before new insulation goes in, because covering a leak or a bad wire just hides it until it costs you more.
A trade learned on the job
I grew up working my dad's insulation jobs and started this business in 2013, so I've been through plenty of older attics like yours and know where they usually come up short.
Honest about what can wait
If your attic already has enough in it and the gaps are sealed, I'll tell you that you don't need us yet, instead of selling you more fill you won't feel.
How we insulate an older attic, step by step
On an older home, I work with what's already up there instead of tearing it all out. If the house still has old knob and tube wiring, that gets dealt with first, because burying live wiring under insulation hides a problem you don't want hidden. Then we seal the attic floor, closing the gaps around can lights, pipes, wires and the hatch, so the new attic insulation isn't fighting a draft. We set baffles, guides at the roof edge, so the eave vents keep breathing, and we blow the fill in level all the way out to the edges, where a lot of attics end up thinnest.
People often ask about spray foam insulation instead. Foam costs more, and it seals air while it insulates. For most attics, sealing the gaps and topping up the loose fill does the job for less, so that's where I usually land, unless your ductwork runs through the attic and sealing the whole space with foam starts to earn its cost.
Here in Hesperia, the attic matters more than people think. Most houses have vented attics, and on a hot day a vented attic runs hotter than it is outside, a lot hotter if it doesn't breathe well, and all that heat sits right over your ceilings. When a job here needs a permit, the city reviews it and sends inspectors out to check the work on site. We do the same work in Victorville, Apple Valley, Phelan and the other cities around Hesperia.
When adding insulation is worth it
The room over the garage
That room sits over a space nobody heats or cools, and its ceiling is often the thinnest spot in the house. It's one of the calls we get most often.
Old insulation that's thin or dirty
A few flattened inches in an older house is normal. If it's dry and clean we build on it, and if it's soaked or full of droppings it comes out first.
Shops that won't hold temperature
Shop and building owners call us when a space bakes all afternoon or loses its heat overnight. We use the same order there, sealing first and insulating after.
Get an estimate written from your actual attic
Send the form and we'll reply within one business day to set a time. I come out, look at the attic myself and write a free estimate, with no obligation to book.
Have the address and areas ready
Tell us the home's address and which spots bother you, whether it's the attic, the room over the garage or the walls, so I know where to look first.
Mention HVAC or roof plans
If new HVAC or a new roof is coming, say so, because that work happens in or over the attic too, and it's better to plan the order once than redo insulation.
Satisfaction guaranteed on every job
Our own crew does the install, not a crew we hire for the day, and I check the work myself before we pack up and leave your house.

Retrofit insulation questions from Hesperia homeowners
Straight answers to what Hesperia homeowners ask before adding insulation to the attic or walls of a house that's already built.
Should my attic be air sealed before I add more insulation?
Yes. In an existing vented attic, every opening in the attic floor should be sealed before more insulation goes on. Adding or replacing insulation is the natural time to do it, since you're working up there anyway, so plan the two as one job. That's how I write it up, and it's the order our crew works in.
Can my walls be insulated without tearing out the drywall?
Usually, yes. The common way is drill and fill, which is fairly low-mess. Small holes go near the top of each wall cavity, the hollow space between studs, and blown-in insulation fills it. The holes can go in from inside or outside, so nobody opens whole walls. I'll look at your walls at the estimate and tell you which side makes more sense.
Do I need a permit to add attic insulation in Hesperia?
Ask the city before work starts, because Hesperia's permit list names HVAC, electrical and re-roofing work but not insulation. Hesperia's Building & Safety Division issues building permits. State energy rules can also come into play, since adding or replacing attic insulation may count as altering the ceiling over a heated or cooled room.
Who can pull a building permit in Hesperia?
Only the property owner, or the owner's licensed contractor or authorized agent, can get a building permit in Hesperia, and it's needed before construction or remodeling begins. So if your job needs one, you don't have to pull it yourself. We take care of the paperwork and the inspections, as I mentioned up top.
Who is allowed to install insulation in California?
In California, installing insulation for heat or sound control falls under the state's C-2 Insulation and Acoustical Contractor license. Without a license, someone can only take minor jobs within the state's $1,000 limit, and only when the work needs no permit and they have no one working for them. We're licensed and fully insured.
