Insulation Company in Cypress, CA
Most Cypress homes were built in the 1960s and 70s, and their original insulation has quietly failed. Batts settle, compress, and stop doing their job. Blown in insulation is the fastest, most cost-effective fix for aging tract housing in 90630, and it’s the service we recommend first for most single-story and two-story homes here. Hollywood Insulation Co installs blown in, attic, and spray foam insulation across Cypress, matching the material to the home’s actual condition rather than whatever’s on the truck. Call (866) 605-6949 for a free attic assessment.
Why Cypress Homes Are Different
Cypress is an Orange County master-planned suburb built largely by S&S Construction and later the Larwin Company in the 1960s and 70s. That means our crews here work almost entirely on aging tract housing and original builder materials rather than new construction. The defining job in Cypress is retrofitting tired, settled attic and wall insulation in homes that have never had a meaningful upgrade since the original build.
What we find in most Cypress attics: fiberglass batts installed 50-plus years ago, now compressed to half their rated thickness. Many of these homes have shallow attics and some floor plans include cathedral or vaulted ceilings, which complicates access and means standard batt replacement often isn’t feasible. Blown in insulation works because it fills irregular cavities and settles into the odd corners these older roof lines create.
Cypress sits in inland coastal Orange County. Attics bake in summer sun and can hit very high temperatures, yet cool marine-layer nights create condensation risk. Seasonal Santa Ana winds add hot, dry spells that stress attic materials and push HVAC systems harder. Effective attic insulation and ventilation matter here for both cooling load and moisture control. A correctly insulated Cypress attic runs noticeably cooler in August and drier in June gloom.
Our Main Cypress Services
Two services account for most of the calls we take in Cypress. Below is what each one involves here.
Attic Insulation in Cypress
Most Cypress attics still hold their original 1960s-70s batt insulation, now compacted and underperforming. We remove or top up that old material, address air leaks around penetrations, and install the right R-value for inland coastal Orange County conditions. Shallow attics and vaulted ceiling sections are common in Cypress floor plans, so we adjust the approach per home rather than forcing the same method everywhere. Full details on Attic Insulation in Cypress.
Spray Foam Insulation in Cypress
For Cypress homes with vaulted ceilings, knee walls, or attics that get punishing summer heat, spray foam creates an air seal batt insulation cannot match. We install both open-cell and closed-cell systems using Icynene and Demilec products. Spray foam handles the temperature swings between Santa Ana heat spells and cool marine nights better than any other material, especially in hard-to-reach roof assemblies. See the specifics at Spray Foam Insulation in Cypress.

Blown In Insulation in Cypress
Blown in insulation is the workhorse retrofit for Cypress tract homes. Because most houses in 90630 were built with R-11-style fiberglass batts in shallow attics, the fastest, cleanest upgrade is blowing loose-fill material over and around the existing layers. This fills the gaps left by settled batts, covers thermal bypasses, and brings typical Cypress attics up to modern R-value with minimal disruption. It’s also the most practical option for the cathedral-ceiling sections common in certain Cypress floor plans, where batt installation would require opening drywall. We install blown in fiberglass and recycled cellulose depending on the home’s needs and the homeowner’s priorities. Learn more about the method itself on our Blown In Insulation page.

What Blown In Insulation Costs in Cypress

|---|---|
| Blown in fiberglass (per sq ft) | $1.00 – $2.80 |

| Typical attic project (1,200 – 2,000 sq ft) | $1,200 – $3,800 |
Is blown in insulation better than batt for Cypress attics?
For most Cypress tract homes, yes. Blown in material fills irregular cavities faster and more completely than batts, especially in shallow attics and around roof framing. It also covers existing settled insulation without a full removal.
Can you blow insulation into existing walls in Cypress without tearing out drywall?
In many cases, yes. For sidewall retrofits we drill small access holes and dense-pack cellulose or fiberglass, then patch the holes cleanly. Give us a call at (866) 605-6949 and we’ll tell you if your walls suit this approach.

FAQs About Insulation Company in Cypress
We schedule Cypress insulation jobs within five to seven business days in most cases. Emergency attic issues after a leak or animal intrusion can sometimes be seen sooner. Call (866) 605-6949 and we’ll confirm the next open slot for 90630.
No. Attic insulation work does not change your home’s exterior appearance and does not require HOA approval in Cypress. Permits are generally not needed for insulation-only retrofits in Orange County. If you have a specific HOA concern, we’ll help you check the language.
Yes. That is most of what we do in Cypress. Older tract homes here respond quickly to blown in and attic upgrades, especially when the original R-11 batts have settled. We assess what’s there now and build on it rather than assuming a full tear-out.
If your Cypress home runs hot upstairs, cold in winter, or your energy bills keep climbing, the attic is usually the first place to look.

What Cypress Customers Say
"Plastic laid from the front door to the attic hatch and they vacuumed the hallway afterward."
— Heather Walsh"Attic was at maybe R-11 from the 1970s and blown in over the top would have just buried the problem. They removed the old material, air sealed the top plates and penetrations first, then blew in to R-49. The upstairs is a completely different house in August."
— Cole Sullivan"Found and sealed a gap around the chimney chase that was basically an open chimney to the attic."
— Brandon Wong
