★ 4.9 167 Google Reviews
★★★★★
"We manage six retail buildings in the Galleria area. Ironclad has the service contract on all of them. The dispatcher answers every call, the techs arrive in branded trucks, and the monthly invoice has never had a single surprise line item. Three years in, never had to escalate."
S., Galleria property management
★★★★★
"Six locations, six different rooftop layouts. Ironclad set up a quarterly PM schedule across all of them and we have not had a Saturday-night cooling emergency since the contract started. The PM finds the small stuff before it becomes the Saturday-night stuff."
C., Sugar Land restaurant group
★★★★★
"Forty-eight units across two buildings. Annual maintenance contract is a fair price and the techs are pleasant to my tenants. Last summer we lost a compressor on a Friday. They had a replacement installed by Saturday afternoon, no overtime billing, contract rate applied."
M., Pearland multi-family operator
★★★★★
"Tenant fit-out for a 14,000 sq ft office. Ironclad fabricated the ductwork, set new VAV boxes, tied into the BAS, and worked overnights so the existing tenants on the floors below were not disrupted. Inspector signed off without a single correction."
J., Energy Corridor office
