What we do

Six services, one crew, two markets.

Residential and commercial work across the Rio Grande Valley and the San Antonio metro — from a single attic to a full metal building.

Spray Foam Insulation

Open-cell & closed-cell, residential and commercial

Seals the envelope where batts and blown-in can't reach — attics, wall cavities, crawl spaces and metal buildings.

Contractor Services

Volume application, scheduled to your build

We work as a sub for builders and GCs, sized to the job and slotted into your timeline instead of holding it up.

Air Sealing

Penetrations, top plates, vents and skylights

The cheapest efficiency win there is. We close the gaps letting your conditioned air straight out of the building.

Why Panda

The owner is on the job, not just on the invoice.

Owner-operated

Daniel Valencia runs the estimates and stays involved through the walkthrough. Customers name him personally in review after review — that isn't an accident.

Two Texas locations

Pharr for the Rio Grande Valley, Adkins for the San Antonio metro. Local crews in both markets, same standard of work.

Premium products only

Icynene and Heatlok systems from Huntsman Building Solutions. We'll tell you the exact product and the rated R-value before you sign anything.

Free assessment, no pressure

We look at the space, tell you what it actually needs, and quote it. If foam isn't the right call for your building, we'll say so.

What to expect

Five steps from first call to final walkthrough.

Free Assessment

Call or send the form. We ask about the building, the problem areas, and your timeline.

On-Site Evaluation

We come out, get into the attic or crawl space, measure, and write a quote against what's actually there.

Schedule

You pick the date. We confirm the product, the thickness, and how long we'll be in your space.

Installation

Masked, sprayed, trimmed, cleaned up. Removal first if the old insulation has to come out.

Walkthrough

We walk the job with you before we leave, and follow up after to confirm the building is performing.

"I can't say enough great things about Panda Insulation! They recently did spray foam insulation in my attic, and the results have been absolutely amazing. My house is finally cool, my AC actually shuts off, and even the garage isn't burning up like before. The difference is night and day! The customer service was exceptional. Daniel was extremely professional — he explained everything clearly, answered all our questions, and even followed up after the job to make sure we were 100% satisfied."

Spray foam, attic — Rio Grande Valley

"Panda Insulation did an amazing job. We had some pest issues and decided to have everything removed and new insulation added. One area is very tight. They did a great job removing everything especially in that area and then insulated everything and even sealed around vents and a skylight that had been an issue. The house feels more solid and not as hollow as before. It made a huge difference."
