Insulation for San Juan’s family homes, old and new
San Juan was founded in 1909 and sits between Pharr and Alamo, about five miles east of McAllen. Most people know it for the Basilica of Our Lady of San Juan del Valle, one of the largest churches in South Texas. Away from the shrine, San Juan is mostly a city of family homes, and it has grown to about 35,000 people as of 2020.
The older streets in central San Juan have smaller one story houses, many with thin attic insulation and additions that were never insulated well. The newer subdivisions on the edges of town were built to the code minimum of their day. In a Valley summer, both show up as rooms that never cool down. We check the attic, look for gaps and old damaged material, and give you a written estimate. Our crew is bilingual. Hablamos español.
