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.

Spray foam details

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.

The three foams above run on Honeywell Solstice® HFO blowing agent — a global warming potential of 1, versus roughly 1,000 for the older HFC agents still in wide use. Huntsman reports that properly installed closed-cell systems deliver energy savings up to 40%. Coatlok and the intumescent coatings are applied over or alongside those foams, not in place of them.

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

Premium products only

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

“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. That kind of service is rare and so appreciated! The technician who came to do the spray foam was incredibly polite, courteous, and did a fantastic job. Everything was done efficiently and with care. We’re extremely grateful for the service we received and highly recommend Panda Insulation to anyone looking to improve their home’s comfort and energy efficiency. Thank you for everything!”

“Bought a home in Alamo. The insulation was sloppily installed , there was no insulation above the garage, and the ductwork leaked. The attic could get as hot as 145F and the uninsulated garage got up to 105F. The worst energy use was 56 kWh/day. Patched ductwork leaks and use dropped down to 32 kWh/day. After Panda sprayed the underside of the roof deck to R38, and put 2 inches of foam on the ductwork, about 24 kWh/day (without using the electric dryer or oven). Before Panda, air coming out of the registers was around 58F, after insulation around 50F. It only took two days, thanks a million Panda, and especially Daniel with so much experience.”

“Panda Insulation exceeded my expectations. They were punctual, professional, and incredibly thorough with the foam insulation work. The crew was respectful of my property, took time to explain the process, and completed the job efficiently without cutting corners. You can tell they take pride in their work. The quality of the insulation is excellent, and I’ve already noticed a difference in indoor comfort. I wouldn’t hesitate to hire them again and highly recommend them to anyone looking for reliable, top-notch insulation services.”

“Daniel received my call and said he could meet with us that day. The first impression after hearing a very detailed description of how foam insulation was the best product to use - was amazement. He did not skip a detail about our particular situation we were in solving our high cost of electricity. We spent several days in meetings with Daniel to review all options. We believe that the right decision was made. He finished our attic foam insulation today. Overall Daniel presents his product with transparentcy and we trust him.”
