My Husband decided our energy bills were too high & explored options to bring them down. We added insulation & that helped a lot. What took it the extra mile was the door hatch sealing- (we have 4 that was leaking hot air) and the solar attic fans.
My home is always comfortable & the AC is working less hard. The guys are very respectful & professional. Highly recommend.

I recently had Koala Insulation of Baton Rouge install blown-in attic insulation and do some air sealing in our home here in Baton Rouge, and I couldn’t be happier with the results. From the first call, their team was responsive, professional, and easy to work with. They came out quickly for a free evaluation, explained everything clearly (including the expected energy savings), and gave us a fair quote with no pressure.

The crew arrived on time, worked efficiently, and left the place spotless—no mess in the attic or house afterward. The difference is already noticeable: our home feels more comfortable, and I’m looking forward to seeing the drop in our cooling bills this summer.

If you’re in the Baton Rouge area and need insulation work (attic, spray foam, air sealing, etc.), I highly recommend Koala. Great local company that does quality work and truly stands behind their service. Would use them again without hesitation!

We had Koala Insulation add insulation to our attic, and the experience was outstanding from start to finish. Their customer service is top-notch, and every employee we interacted with was professional, courteous, and knowledgeable.

The installation team did an incredible job. They were thorough, paid attention to every detail, and made sure nothing was missed. You can tell they take pride in their work and genuinely care about doing the job right.

The best part is that we’ve already noticed a difference in the comfort of our home. It’s clear that the insulation is making an impact.
If you’re considering adding insulation to your home, I highly recommend Koala Insulation. Excellent service, excellent workmanship, and excellent results!

Extremely professional and courteous. Started immediately and worked steadily until job was finished. Cleaned up completely (even vacuumed) and shared pictures from the job. Thanked me for business.

Excellent communication, provided all that was agreed to in a prompt and professional manner. Did a thorough job, including taking time on prep work prior (doing it the right way – with baffles and depth gauges). The installation of the blown insulation was up to or exceeding the spec, and we have the photos to prove it!
1 week later – attached is my daily report from Entergy for the past week – even better than I hoped. BTW, Monday’s high was 93 degrees.

How much does insulation cost in Gonzales?

Blown-in attic insulation in the Gonzales area typically starts at $1.60 per square foot, so a standard 1,500 sq ft attic usually lands in the $2,400 to $4,000 range. Spray foam costs more per square foot but seals air leaks at the same time. Final price depends on attic size, the R-value you’re starting from, and the insulation type. Every quote is written, itemised, and free.

What type of insulation is best for a Gonzales attic?

For most Gonzales homes, blown-in cellulose over the attic floor combined with air sealing gives the best result for the money — it fills gaps around joists and wiring that batts leave open. Spray foam is the better choice when you need to air seal the roof deck itself or convert the attic into conditioned space. We recommend a type after inspecting your attic, not before.

What R-value do I need for an attic in Gonzales?

Gonzales sits in climate zone 2A, where the Department of Energy recommends R-30 to R-49 for attics. Most Gonzales homes built before 2000 come in around R-11 to R-30, which is well short for our hot, humid Gulf Coast summers. Reaching R-38 or higher is also the level most Entergy and local utility rebate programs look for. We measure your current R-value during the free evaluation and tell you exactly where you stand.

What areas around Gonzales do you serve?

Koala Insulation of Gonzales serves Gonzales and the surrounding Baton Rouge area across Greater Baton Rouge. Not sure if you’re in range? Call (225) 457-1001 and we’ll confirm in a minute.

How long does the job take, and do I need to leave the house?

Most attic insulation jobs are finished in a single day, and you can stay home for blown-in work. Spray foam requires you to be out of the house for roughly 24 hours while it cures. We’ll tell you which applies before we book.
