Commercial Spray Foam Insulation (Closed Cell) in San Juan, TX

M&R Foam Insulation specializes in closed cell spray foam insulation for homes and businesses across the Rio Grande Valley — serving McAllen, Brownsville, Harlingen, Edinburg, Mission, Pharr, and surrounding South Texas areas. With a top-tier R-value and built-in moisture resistance, closed cell spray foam cuts energy bills and strengthens your structure year-round.

When maximum energy efficiency and structural integrity matter, closed cell spray foam is the gold standard — and M&R Foam Insulation is the Rio Grande Valley's trusted choice. We serve McAllen, Edinburg, Brownsville, Harlingen, San Juan, Mission, Pharr, Weslaco, Alamo, Elsa, Mercedes, San Benito, Alton, Sullivan City, Rio Grande City, and throughout South Texas. Closed cell spray foam has an R-value of approximately R-6 to R-7 per inch and expands into a solid, impermeable layer that also functions as a vapor barrier — preventing moisture infiltration that leads to mold and structural damage. In a region like the Rio Grande Valley, where humidity is a year-round concern, this moisture protection is a critical advantage. It also adds rigidity and racking strength to walls and roofs, benefiting South Texas properties that endure extreme summer heat and severe weather. Residents and builders throughout McAllen, Edinburg, Harlingen, and across Hidalgo and Cameron County rely on M&R Foam Insulation for precise, professional installations that meet code and deliver real energy savings.

Brandon was very thorough on his walkthrough with the services that M&R offers. He was able to detail the work that would be done for old blown insulation removal and foam insulation addition into my attic. He was also able to give information on financing options and how the install and moving forward with M&R would improve not only my energy bill but overall circulation of AC. M&R did great work with the old insulation removal and I appreciated that they notified me of a roof leak that I was unaware of. M&R offered to send another crew to be able to assess the leak and patch it before the foam insulation was installed. Communication was great with the work crews and office to guarantee that the job would be done completely and professionally.

Francisco made the whole process easy and straightforward, clearly explaining everything with no surprises, and the installers did a phenomenal job with the spray foam. We’re already noticing a much cooler attic, and we’re excited to see the difference in our electric bill!

We had a great experience with this foam insulation company. The work turned out really well, and we are very happy with the results. There was a small issue during the process, but Eliseo, the owner, took responsibility and made sure it was fixed properly. I really appreciate that he stood behind his work and made sure we were satisfied. A special thank you to the guys who came out and did the work. They worked hard, were respectful, and did a great job. I wish I knew their names so I could thank them personally, but I definitely want them to know that their hard work is appreciated! Great customer service, good quality work, and very professional. We definitely recommend them! ⭐⭐⭐⭐⭐
