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.

I was so impressed by the sheer competence and kindness of the team that handled our repair. They arrived exactly when they said they would, diagnosed the problem quickly, and kept the worksite immaculate😍 Fantastic service overall!
Prior to engaging Frontline, we consulted with four other companies regarding the roof leak. Following a comprehensive roof inspection, we decided on a full roof replacement. Julio provided a detailed explanation of the materials, pricing, and addressed all our inquiries concerning the project's execution. Throughout the process, our project manager, Gabriel, was readily available to address any concerns. The team demonstrated professionalism and efficiency, completing the project within the agreed-upon timeframe. The crew worked diligently throughout the day. The outcome was a leak-free roof, ensuring our peace of mind for the foreseeable future.
My sister in law referred me to Frontline Solutions. I called the company number and by that evening I had a representative, Lilly Hernandez, at my home. I had requested a quote for spray insulation to my attic. Lilly got right to work by taking photos, sitting me down and telling me her findings. She was very knowledgeable, professional and great at answering all my questions and addressing my concerns. I decided to accept the quote and am eager to see the job completed. Thank you Lilly!!

I recently hired RGV Insulation for spray foam, and I couldn't be happier with the results. Their workers were professional, punctual, and really easy to communicate with. If I ever had a question , they always took time to explain which options were better for me. Also, something that stuck to me is that they did their best not to interfere with the people inside the house, making sure their route to the work area didnt bother anyone in the slightest... such attention to detail is rare! On the day of the job, they worked efficiently and left everything cleaner than when they started. The difference in comfort inside the house was noticeable immediately, and it's clear they take pride in doing quality work. I highly recommend RGV Insulation for their services. They won't disappoint!
