Why Your AC Has Been Working So Hard

Three things go wrong with attic insulation Austin homes deal with at the same time. By year 20, they’re all happening at once.

Settled & Compressed

Attic insulation settles 10 to 30 percent over its lifespan. By year 20, your R-30 batts are performing closer to R-20, and the AC is paying for it every July afternoon.

Below Code Depth

Code minimum in Austin is R-38. Most pre-2010 homes were built to R-19 or R-30 and never topped off. You are short 8 to 16 inches of coverage and don’t know it because nobody goes up there.

Contamination & Disturbance

HVAC techs walk on it. Electricians push it aside. Rodents and roof leaks foul it. After 15 to 20 years, what looks like coverage from the access hatch is patchy and half-effective everywhere it actually matters.

Austin Attics Need More Than a Top-Off

The standard builder-grade insulation just doesn’t cut it when it’s 105 degrees for 60 straight days. Here is the reality of what 20-year-old attic insulation is actually doing, and what blown-in fiberglass to R-49 fixes.

Blown in fiberglass vs blown-in cellulose vs batts

Three materials cover most attic insulation Austin jobs, and blown in insulation Austin homeowners ask about most is loose-fill fiberglass. Each has a use case. We’ll tell you straight which one fits.

Blown-in fiberglass

Loose-fill fiberglass blown to depth with a machine. R-value is about 2.5 per inch. For an Austin attic targeting R-49, that’s roughly 19 to 20 inches of coverage. It does not settle as much as cellulose, holds its R-value over time, and works well in vented attics. This is what we install on most retrofit jobs.

Blown-in cellulose

Recycled paper treated with borate for fire and pest resistance. R-value is about 3.2 to 3.7 per inch, so you hit R-49 with less depth than fiberglass. Cellulose is denser, so it sound-dampens better and seals small air leaks more aggressively as it packs in. Settles 10 to 15 percent over the first year, which we account for at install.

Fiberglass batts

The pink rolls you’d recognize from any home center. Useful for new construction, knee walls, vaulted ceilings, and rim joists. Not the right product for a retrofit attic floor because batts leave gaps wherever joists, wires, or ducts get in the way. We use them where they fit, not because they’re cheap.

Most Austin homeowners ask which is better. Honest answer: for a flat attic floor, blown-in fiberglass is the workhorse and what we recommend most often. Cellulose has its place when you need higher R per inch or sound damping. Batts are for specific framing situations, not bulk attic coverage.

What attic insulation Austin homeowners pay

Most contractors hide attic insulation Austin pricing because they want you on the phone before you see numbers. We’d rather put it on the page.

Job minimums: $1,400 for fiberglass attic work, $2,750 for wall additions. All pricing subject to change based on final on-site assessment.

The reason most contractors won’t put numbers on a page is that depth, access, prep work, and existing conditions all affect the final estimate. A 1,800 sq ft attic with a clean deck is one number. The same attic with rodent contamination and 1980s blown-in cellulose that is compressed and damp is a different number.

We give you the real estimate on-site after we have seen the job. The numbers here are what you can plan around.

What Install Looks Like

1

Morning Arrival

Crew arrives, sets up rig.

2

Prep & Protect

Floors masked. Old insulation cleared.

3

Air Sealing

Penetrations sealed before the blow.

4

The Blow

Insulation blown to depth, gauges verified.

5

Final Walk

Lead walks the finished job with you.

The Full Version

Morning of the job. The crew arrives in the H&O truck with the blowing rig. The same lead installer who walked your job at the estimate is the one running the install. We protect floors and any belongings near the attic access.

Prep. If old insulation is coming out, that happens first. Vacuum trucks, contained removal, no fiberglass dust through your house. If we’re topping off clean existing insulation, we inspect for rodent activity, leaks, or compressed areas before adding depth.

Air sealing. Before insulation goes down, we seal the gaps where conditioned air leaks into the attic. Top plates, wire penetrations, plumbing chases, recessed light cans. This is the step most contractors skip or charge extra for. We do it on every job at no upcharge. It’s the step that makes the insulation actually work.

The blow. One installer runs the hose in the attic, the other feeds the machine on the truck. We blow to the spec’d depth, marked with depth gauges so you can verify coverage. The installer in the attic walks every corner, edge, and soffit.

Final walk. Your crew lead walks the finished job with you before they leave. We show you the depth gauges, the coverage at the eaves, and the air-sealing work. If anything isn’t right, we fix it before we go.

Total time on a typical attic insulation Austin job: 4 to 6 hours for a top-off, one full day for most reinstalls, two days for big jobs with full removal and sanitization. We tell you which bucket your job falls in at the on-site estimate, so you can plan your day before we ever show up to do the work.

What Changes After Installation

Austin attic insulation done right changes how the house feels. Our Austin attic services crew sees it on every job, and homeowners feel the difference within the first cooling cycle:

  • Upstairs rooms that ran 5 to 10 degrees hotter than the rest of the house even out.

  • AC runtime drops. Most homes see 15 to 25 percent shorter cycle times in summer.

  • Drafts at outlets, can lights, and ceiling fixtures stop. That’s the air sealing doing its job.

  • Winter heating bills drop too, which most Austin homeowners don’t expect until the first January cold front.

  • Dust in upstairs bedrooms drops. Sealed attics push less attic air into living space.

Questions about Attic Insulation Austin Homeowners Ask

How do I know if my attic needs more insulation?2026-05-08T05:12:41-05:00

Walk into your attic and look at the joists. If you can see them, you need more. Building code says you should be looking at 14 to 16 inches of loose-fill above the joist tops in this climate. Most Austin homes built before 2010 are well short of that.

Can you blow new insulation over the old stuff?2026-05-27T15:55:54-05:00

Usually yes. If the existing attic insulation Austin homes have is dry, clean, and not compressed, we can top it off. If it’s contaminated, water-damaged, or rodent-impacted, it has to come out first. We make the call on-site after we inspect.

What R-value should my Austin attic have?2026-06-19T14:20:58-05:00

Code minimum for attic insulation Austin homes is R-38. We install to R-40 as our standard on full reinstalls, and we guarantee that R-40 in writing. If you want to go further, we can install to R-49 or R-60 as an upgrade. The cost difference between R-40 and R-49 is small. The performance difference is real but smaller than most homeowners expect. R-40 already gets you the bulk of the gain over code minimum.

How long does blown-in insulation last?2026-05-08T05:14:15-05:00

Fiberglass holds its R-value for the life of the house if it stays dry and undisturbed. Cellulose holds up well too, with some settling in the first year that we account for. Real-world enemies are roof leaks, HVAC techs walking on it, and rodents. Most attics need attention every 20 to 30 years, mostly because of those three things, not because the insulation itself failed.

Do you do air sealing as part of the job?2026-06-19T14:21:39-05:00

Yes, on every job. Insulation without air sealing is half a job. We seal top plates, wire penetrations, plumbing chases, and recessed lights before we blow. Air sealing is included in the install pricing at no upcharge. That is roughly $800 in value most contractors charge separately for. It is the single biggest reason our installations actually perform the way insulation is supposed to.

What’s included in a full reinstall?2026-05-08T05:15:20-05:00

Three things in one price. Air sealing the attic floor before we blow. Sanitization of the attic space if there has been any rodent activity, water staining, or general buildup over the years. And the new insulation itself, blown to R-40 and guaranteed in writing. Most contractors charge for these as three separate line items. We bundle them because doing one without the others is leaving money on the table for the homeowner.

What about my recessed lights? Don’t they need clearance?2026-05-08T05:15:34-05:00

Older non-IC-rated cans need a 3-inch clearance from insulation. We either install IC-rated covers over them (code-compliant, cheap, quick) or we maintain the clearance and seal around the boxes. We don’t bury non-IC cans. Fire risk.

Will more attic insulation help in winter?2026-05-08T05:15:49-05:00

Yes. The R-value works both directions. Most Austin homeowners notice the summer benefit first because that’s when the system is fighting hardest, but the winter heating bill drops too. The house also holds temperature longer when the AC or heat cycles off.

Are you licensed and insured?2026-05-13T04:41:59-05:00

Texas does not require a state license for insulation work. We carry $1M / $2M general liability through Travelers. Certificates available on request.

How much does an attic insulation contractor charge in Austin?2026-09-09T12:34:04-05:00

A blown-in fiberglass top-off runs $1.38 per square foot, and a full reinstall to R-40 is $2.00, with air sealing included on both. Most Austin attic insulation contractors keep pricing off the page. Ours is listed, and you get the firm number on-site.

Do you do attic insulation removal and replacement, or just top-offs?2026-07-04T08:12:40-05:00

Both. If the existing insulation is clean and dry, we top it off. If it’s contaminated, wet, or compressed, we remove it first, then reinstall. You get the removal and replacement priced separately so you can see what each part costs.

Is blown in insulation better than batts for an Austin attic?2026-07-04T08:13:01-05:00

For a flat attic floor, yes. Blown in insulation fills around joists, wires, and ducts with no gaps, which batts can’t do once they hit an obstruction. We use batts for knee walls, vaulted ceilings, and new construction, not bulk attic coverage.
