Retrofit insulation in Redding CA - rooms that finally hold their temperature
Hot upstairs or a drafty older house? We find where the heat is getting out, then add insulation so your rooms stay comfortable.
Does my Redding house need more insulation, and what has to happen first?
Retrofit insulation in Redding, CA, means adding insulation to a house that's already built. Most often we blow loose fill through a hose across the attic floor or into the wall cavities, so your ceilings and walls slow the heat coming in each summer and leaving each winter.
Most calls start with a room that won't stay comfortable. It might be a hot upstairs, a room over the garage that never cools off or a power bill that keeps creeping up, and in an older house the real reason isn't always the obvious one. The price mostly turns on how big the attic is and how many inches are already up there. It also depends on whether old or damaged material has to come out first through insulation removal, how many gaps need sealing and whether the walls are part of the job. The schedule depends on what I find first, because wet insulation, poor venting or old wiring gets dealt with before anything new goes in. Your written estimate lays out that order and the price for your house.
How we do retrofit insulation on an older house
Adding to an older house means working around what's already there, so I start by looking at the attic, the walls and the age of the home before I suggest anything. If lead paint, old wiring or vermiculite could be in play, we plan around it with you first. Anything wet, moldy or venting into the attic gets fixed before new material goes over it, because covering a problem only hides it. Then our crew does the air sealing, closing the gaps around can lights, pipes, wires and the attic hatch so the new insulation isn't fighting a draft. We set baffles at the eaves so the vents keep breathing, and we blow the new layer evenly out to the edges of the ceiling. Deep in the middle and thin at the edges is backward, and we find it in a lot of attics.
For most houses the retrofit is really an attic insulation job, sealing the gaps and topping up loose fill over what's already there. That's the route I usually recommend because it costs less and does the work. Spray foam insulation costs more but seals air while it insulates, so it earns its price when your ductwork runs through the attic and needs that seal around it.
What changes retrofit insulation in Redding
The guidance for an existing attic is to reach insulation levels that meet or beat California's current energy code, so I compare what's in your attic to that code when I write the estimate. If cost is what's holding you back, the Low Income Home Energy Assistance Program gives income-qualified homeowners and renters services that may include attic insulation. SHHIP takes applications at 530-378-6905, and that call is worth making before you decide.
Many of the houses we're called to around Redding are older homes. They tend to have a few settled inches between the joists, a leaky attic hatch and summers that push heat straight through the ceiling, so the hatch and the edges get as much of our attention as the middle. We see the same houses on jobs in Shasta Lake and Anderson, and we work in other cities around Redding too. If you're nearby and don't see yours, give us a call and ask.

Questions before you book retrofit insulation
How do I know if my attic needs more insulation?
If you can easily see the attic floor joists, the insulation is level with them or below them, and you should add more. If it sits well above the joists, you probably have enough and more may not pay for itself, so that's the first thing I check before recommending anything.
Should air sealing come before adding insulation?
Yes, seal first. Money spent on insulation can go to waste when the holes and gaps in the ceiling, walls and foundation are left open. Wet insulation, moldy or rotted framing, vents blowing moist air into the attic and poor attic ventilation should all be fixed before the sealing starts.
How are existing walls insulated without tearing them out?
The usual way is drill and fill. A crew drills small holes near the top of each wall cavity and blows insulation in from inside or outside the house. In homes built before 1980, wall work can bring in lead safety rules depending on how much is disturbed. Insulation also can't go on or around knob-and-tube wiring because of the fire risk, so I look for both first.
How much does blown-in attic insulation cost in Redding?
Across the US, installing blown-in attic insulation usually costs about $4 to $7.75 per square foot. That's a national figure, not a Redding quote. Your price depends on the attic's size, what's up there now, whether old material comes out and how much sealing it needs. The written estimate after I've seen your attic gives you the number for your house.
What is the best way to deal with vermiculite insulation in my attic?
Leave it undisturbed and treat it as if it may contain asbestos, which is what the EPA recommends. If you decide to have it removed, that work goes to a trained, accredited asbestos abatement contractor who is independent of whoever assessed it. We plan the rest of the insulation around that.
Do I need my gas furnace or water heater tested after air sealing?
Testing before and after sealing is worth doing. In some cases, sealing a house can make a naturally venting gas or oil appliance back-draft exhaust into the home. Tell me what appliances you have at the estimate, and we'll fit that testing into the plan.

I come out myself to look at the job and write the estimate, and our installers do the work that follows. Before we call it done, I check it with you, so the person who planned the job is the one who signs off on it.
Running this business since 2020
I learned the trade on an insulation crew and started this business in 2020, and we're best known for older houses that don't behave the way they should. I'd rather tell you a job isn't worth doing yet than sell you something that won't help.
Licensed and fully insured in California
We're licensed and fully insured. The Contractors State License Board gives insulation work its own classification for anyone who installs insulation to control heat or sound, so it's fair to ask any crew you're comparing about their licence.
On an older house, the order of the work matters as much as the insulation itself. Book a visit and I'll come look at your attic with you.

If the attic is the only place your house falls short, topping up the attic floor on its own may be all the job needs.
Spray foam insulation
When ducts run through a hot attic or a space needs sealing and insulating at once, foam can be worth the higher price.
