💬 Recent Verified Customer Experiences:
"Our old chain-drive opener was grinding horribly and finally gave out on a Saturday. The technician from Union Door walked me through replacement options clearly without any high-pressure upselling. Installed a belt-drive smart opener with battery backup and camera. Programmed both vehicle remotes and helped us configure the smartphone app before leaving. Extremely professional and clean work."
"We replaced our outdated builder-grade doors with a new R-16 insulated carriage house door through Union Door. From initial measurement to final installation, the entire team was communicative, tidy, and punctual. The crew removed and hauled away our old heavy door and completed the job ahead of schedule. Noticeable temperature improvement in the garage immediately."
"Our facility warehouse roll-up door was binding at top clearance and stalling the motor. Union Door dispatched a commercial service team within an hour. They serviced the counter-balance springs, tightened the guide tracks, and adjusted the limit switches. Reliable, licensed pros who know commercial overhead hardware thoroughly."
