"We replaced our outdated builder-grade doors with a new R-16 insulated carriage house door through Duncan Door Service. 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. Duncan Door Service 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."
"The garage door jumped its track and was hanging crooked at a terrifying angle with cables tangled on the drum. Called Duncan Door Service's emergency dispatch and someone was at our driveway in 45 minutes. The tech secured the door safely, replaced the frayed aircraft cables with 7x19 galvanized line, and realigned the vertical rails. Highly recommended for emergency repairs in Saint Charles."
