Most attic insulation projects in North Tustin run between $1,800 and $6,500, depending on attic size, access, and whether you need old material removed first. Woolsey Attic Insulation gives you the exact written number before any work starts, then shows up in the promised window and stands behind the job for 365 days in writing.

A live person answers, day or night.
Why Woolsey Attic Insulation Is North Tustin’s Preferred Attic Insulation Company
North Tustin homeowners tend to ask the same questions: what’s actually in my attic right now, what R-value should it be, and how much will it really cost? We answer all three on the first visit. Glenn Hartley started with Kingswell in 2002, and the model has never changed – a written price before work begins, background-checked uniformed technicians on the job, and a guarantee that says if it’s not right within 365 days, we come back and fix it at no charge. No fine print.
The homes here are not tract builds. They’re custom and semi-custom, largely from the mid-1960s through the late 1980s, with cathedral rooflines, vaulted ceilings, and multi-level framing that make every attic different. A crew that only knows standard rectangular attics will struggle in North Tustin. Ours doesn’t. We’ve worked on enough Arlington Avenue contemporaries and Crest de Ville estates to know how framing, knee walls, and recessed can lights complicate a blow-in – and how to handle them so the county inspector signs off on the first pass.
Attic Insulation Removal in North Tustin
Attic Insulation Removal in North Tustin usually costs between $1,200 and $3,000 for a typical custom home, and it’s the right call when the original fiberglass has compressed, been soaked by a roof leak, or been fouled by rodent activity. Homes built in the 1960s through 1980s often still have their original batts, and in this inland foothill climate those batts have been baking for decades. They don’t insulate anymore; they just sit there, settled and useless, while your air conditioner works against 130°F attic air every summer afternoon.
When the old material has to go
If there’s been a leak over the garage or along a valley rafter, wet fiberglass loses its loft and never recovers. If rodents have nested in it, removal is the only safe answer. We vacuum out the old material, dispose of it properly, and prep the attic for fresh insulation – all before we quote you a single number for the new install.
County permits, done right
North Tustin is unincorporated Orange County. That means insulation permits and inspections go through the county building department, not the city of Tustin or Orange. A contractor who habitually files with the wrong jurisdiction gets a flag and a re-inspection delay – and you get to wait another two weeks. We file with the county from the start, so the job doesn’t stall.
Blown In Insulation in North Tustin
Blown In Insulation in North Tustin typically runs $1,600 to $4,800 for a full attic, with the final number depending on square footage, target R-value, and how much air sealing the attic needs. It’s the most common retrofit we do here because it’s the only practical way to get insulation into the irregular cathedral vaults and multi-level cavities these custom homes were built with. Loose-fill fiberglass or cellulose blows into place through a hose, filling voids that batts could never reach.
Vaulted ceilings and knee walls
A blown-in job on a 1970s custom with a vaulted great room is not a simple open-attic project. The ridge bays, the knee-wall cavities, the transitions where the roof line changes pitch – each one needs a different approach. We work around framing, install baffles where needed to protect soffit ventilation, and air-seal before we blow. That order matters; sealing after the fact means pulling insulation aside.
Blown-in over existing material
Sometimes the old insulation is dry, clean, and just under-performing. In that case we can blow fresh material over the top to reach R-49 without a full removal. The key is air sealing first: if the recessed can lights, top plates, and chase openings aren’t sealed, blown-in insulation gets bypassed by air movement and you’re paying for material that can’t do its job. We check for bypasses on every job in North Tustin, because these older homes have plenty of them.
Trusted Brands We Service in North Tustin
We don’t push whatever happens to be on the truck. Woolsey works with eight insulation manufacturers – including Johns Manville, Knauf, Rockwool, and CertainTeed – and the recommendation we give you is based on your specific attic and budget, not our inventory. For most North Tustin blow-ins we spec either Owens Corning or Johns Manville loose-fill fiberglass at R-49; for walls and cathedral sections where air sealing matters most, Rockwool or CertainTeed batts often make more sense. Local parts and materials are stocked for quick turnaround across North Tustin, from the neighborhoods around Foothill High School to the hillside streets off Cowan Heights Drive.
Common Attic Insulation Problems We See in North Tustin Homes
- Settled and compressed 1960s-1980s fiberglass batts. In vaulted and cathedral framing, the original material has typically slumped to between two and four inches of effective depth, leaving the ridge and knee-wall bays nearly uninsulated. The top floor runs hot year-round, and during Santa Ana events it becomes genuinely uncomfortable.
- Permit filings sent to the wrong jurisdiction. North Tustin is county territory, not city. Contractors who pull permits in Tustin or Orange get flagged by the county and the inspection date gets pushed back – we’ve seen it add weeks to a simple project. We file with Orange County from day one.
- Unsealed recessed can lights and chase openings. Multi-level floor plans from this era have dozens of penetrations between the attic and living space. Air leaks through them, and blown-in insulation gets bypassed almost immediately – the material’s there, but the heat transfer never stops.
- Insufficient attic ventilation upgrades after remodel work. When homeowners add on or re-roof, the original soffit and ridge vents often stay untouched. An attic that can’t breathe pushes heat down into the house, and new insulation alone won’t fix it. We prep baffles and ventilation as part of the job.

FAQs About Attic Insulation in North Tustin
Why does my North Tustin attic insulation need a county permit instead of a city one?
North Tustin is unincorporated Orange County, so building permits and inspections are handled by the Orange County building department rather than the city of Tustin or Orange. Filing with the wrong jurisdiction triggers a rejection and a re-inspection delay that can add two to four weeks to the project. We file with the county from the start. Call (325) 240-5411 and we’ll walk you through the exact permit path for your street.
My North Tustin home was built in the 1970s with a vaulted ceiling. Can you still blow in insulation?
Yes, and we do it regularly. Vaulted and cathedral ceilings from this era typically have shallow rafter bays that batts were never sized for. We blow loose-fill fiberglass into those cavities working around the framing, install baffles to protect ventilation, and air-seal the transition points. Expect the upper-floor temperature difference to shrink noticeably. Call (325) 240-5411 for a free attic inspection and we’ll show you what’s happening in those rafter bays.
Why does my top floor get so hot during Santa Ana winds when my neighbors in Tustin proper don’t complain as much?
North Tustin sits at the base of the Santa Ana Mountain foothills, directly in the path of downslope wind events that can spike outdoor temperatures 20 to 30 degrees within hours. Homes here also have sharper overnight temperature drops than coastal Orange County, so the building envelope gets hit with rapid thermal cycling. If your attic insulation is original and settled – typical for 1960s to 1980s construction – there’s little resistance to that heat load. Upgrading to R-49 with proper air sealing is the fix.
Do I need attic insulation removal, or can you just add blown-in over what’s there?
It depends on the condition of what’s up there. If the existing batts are dry, clean, and merely underperforming, we can blow fresh material over them to reach R-49 without removal. If they’re compressed to the point of being useless, water-damaged, or soiled by rodents, removal first is the only honest answer. We’ll inspect and tell you straight – and the inspection is free. Call (325) 240-5411 to schedule one.
What R-value makes sense for a North Tustin attic?
For most North Tustin homes, R-49 is the target for attic floors, in line with current Title 24 guidance for inland CEC climate zones. That’s roughly 14 to 16 inches of blown-in fiberglass, depending on the product. Older pre-Title 24 homes here were often built with R-19 or less, effectively, after decades of settling. The jump to R-49 is usually the single biggest energy upgrade a North Tustin homeowner can make, and it’s exactly what we install. Call (325) 240-5411 for a written quote – free, no obligation.
