Reviews
Trust earned on the job
“J Castillo Construction replaced our entire roof after a storm. The crew showed up on time, protected the landscaping, and walked me through every material choice. Our house looks brand new from the curb.”
Maria Delgado

“We had a stubborn leak around a skylight for years. The expert crew at J Castillo found the flashing issue in one visit, replaced the skylight, and sealed everything properly. No drips since—and they cleaned up like pros.”
James Porter

“Hired J Castillo Construction for a flat roof on our addition and seamless gutters. The expert crew delivered a clear estimate, solid communication, and finished work that looks sharp. I’ll call them again for the main house.”
