Blown-in insulation in Santa Cruz CA - an even layer across your whole ceiling
Hot upstairs rooms and a climbing power bill usually trace back to a thin attic. We fill it evenly, edge to edge.
Will blown-in insulation fix my hot upstairs and drafty rooms?
Blown-in insulation is loose cellulose or fiberglass blown through a hose onto your attic floor. For most Santa Cruz homes with a thin or patchy attic, it's the most direct way to slow the heat moving through the ceiling into the rooms you live in.
Most of my calls start with a room that won't stay comfortable, like the one over the garage or an upstairs that bakes by afternoon, plus a power bill that keeps creeping up. Often it's an older house with only a few inches of insulation in the attic. The price depends on how big the attic is, how many inches you already have, how many gaps need sealing, and whether old material is soaked or full of droppings and has to come out first. The schedule turns on those same things plus whether your address needs a permit, so I'd rather look than guess, and the on-site estimate is where you get your own number.
How we put in blown-in insulation
I start by going up with a flashlight and a ruler, because what's already there decides everything else. We check how many inches you have and whether any of it got soaked by a roof leak or turned into a nest, since fresh material laid over that just hides the problem. Next our installers seal the gaps around can lights, pipes and the attic hatch so the new layer isn't fighting a draft. Then we set baffles, small chutes at the eaves, so the vents keep breathing and the insulation doesn't spill into the overhang. Only then do we blow, aiming for an even layer across the whole ceiling with the edges as full as the middle, which is where a lot of jobs come up short. Before we pack up, I'll show you the depth so you've seen it yourself.
If what's up there has to go first, that's insulation removal, and we finish it before anything new goes in. If the attic is only part of it and you've also got cold floors or drafty walls, we can plan the whole house as one home insulation job. There's one trade-off I'll name plainly. Spray foam costs more and seals air while it insulates, but sealing the gaps and topping up with loose fill usually wins, unless your ductwork runs through the attic, and then foam is worth a real look.
Why Santa Cruz homeowners call us for blown-in insulation
I come out for every estimate
I come out to every estimate myself, and while our installers do the work, I check in on the job as it goes. The person who looked at your attic is the one answering your questions.
Painting first, insulation since 2023
I painted houses for years and kept walking into cold, drafty rooms that no coat of paint could fix, so I learned insulation on other crews and started this business in Santa Cruz in 2023. That's why I'd rather spend a few extra minutes explaining your attic than leave you guessing about it.
Licensed in California, fully insured
We're licensed and fully insured. California's contractor license board treats installing insulation, for heat or for sound, as its own kind of contracting work, so it matters who's working above your ceiling.
Permits checked for your address
The County requires a building permit unless the state and county building codes specifically exempt the work. We work across the county and over the hill in the South Bay, so I check with the city or county office that covers your address, and when a permit is needed we take care of it and tell you up front.
On this job, the order matters more than anything, so old problems get fixed and gaps get sealed before a single bag is blown. When you're ready, call (831) 201-6061 or send us a note, and it helps to have your rough attic size and the kinds of ceiling lights you have handy.
Get your attic checked and a blown-in insulation quote
We reply to every call and message within one business day. I'll set a time to come out, go up in your attic and walk you through what I found and what I'd do, and the estimate is free with no obligation. Your satisfaction, guaranteed.

What people ask about blown-in insulation
How much does blown-in insulation cost in Santa Cruz?
Blown-in fiberglass covering about 1,000 square feet of attic in Santa Cruz usually runs about $900 to $4,300 for the job. That's the going range around here, not our price, and where yours lands depends on what I find when I come out to look.
Is blown-in insulation cheaper than batts?
Usually, yes, because blowing loose fill into an attic generally costs less than laying batts and gives fuller coverage, though installation costs vary from house to house. It also fills odd-shaped spaces and tucks around pipes and framing where batts tend to leave gaps, which is why it suits most attics.
How do I compare blown-in insulation quotes in Santa Cruz?
Ask each contractor what insulation level the quote reaches, because blown attic insulation should meet or beat what current building code calls for, and bids only compare fairly at the same level. The City of Santa Cruz's energy ordinance lists ceiling insulation of R-49 or more, R-value being the measure of how well insulation slows heat, as one of its measures for some projects. I'll tell you what level our quote reaches and whether that measure touches your job.
What happens to recessed lights when you blow in attic insulation?
Under the city's ordinance, on the projects it covers, recessed ceiling lights get covered to the same depth as the rest of the ceiling. Any light that isn't rated to sit in contact with insulation has to be replaced or fitted with a fireproof cover, so I check your lights at the estimate and tell you what each one needs.
Should the attic be air sealed before blown-in insulation goes in?
Yes. The insulation goes on after the gaps in the ceiling are sealed, and since you're already adding insulation, it makes sense to plan attic air sealing as part of the same job. The city's ordinance also notes that cutting air leaks can reduce how well a house dries out, and it advises owners to consider adding continuous ventilation when they tighten things up, so we'll talk that through at the estimate.
What causes thin spots in blown-in attic insulation?
Usually it's insulation blown in too loose, which settles over time and leaves holes and voids, or a crew that piles it deep in the middle and runs thin toward the eaves. Blown-in has to go in dense enough to hold its depth, which is one more reason we show you the depth at the end.
Other jobs that often go with it
- Home insulation
When cold floors and drafty walls bother you as much as the attic does, we can plan the whole house at once.
- Insulation removal
If your old insulation was flattened by a roof leak or is full of rodent droppings, it needs to come out before anything new goes on top.
