Commercial Door & Dock Repair — FAQ
Common questions from facility managers, operations directors, and maintenance teams across Ontario.
How fast can Wilcox respond to an emergency repair?
We offer 24/7 emergency service across Ontario. For most GTA calls, we can have a certified technician on-site within a few hours. Our service trucks are stocked with the most common parts to maximize first-visit fix rates.
Do you use subcontractors for repair work?
No. All Wilcox technicians are direct employees — trained, badged, and background-checked. You always get a Wilcox technician on your site, not a third-party contractor.
What documentation do I receive after a repair?
Every completed job includes a detailed service report with photos, parts replaced, technician notes, and a compliance checklist. Fire door work includes written NFPA 80 drop test certification.
Can you repair any brand of commercial door or dock equipment?
Yes. Our technicians are trained across all major brands — Blue Giant, Hörmann, Rytec, Rite-Hite, Cornell/Cookson, Wayne Dalton, Raynor, and more. We stock common parts for all major manufacturers.
Is a planned maintenance agreement worth it vs. reactive repairs?
Almost always yes. A PMA typically costs 30–50% less per visit than reactive service calls, eliminates emergency callout premiums, and catches wear before it becomes failure.
Do you handle fire door repairs and NFPA 80 compliance testing?
Yes. Wilcox is certified to perform NFPA 80 annual fire door drop testing and issue written compliance documentation. We repair fusible links, closing devices, reset mechanisms, safety edges, and controls.
What is included in a service call for a broken dock leveler?
A standard call includes a full safety inspection, diagnosis of the failure, repair of the issue, and testing before the technician leaves. We document everything and flag additional items for your maintenance records.
Can you repair high-speed fabric or rubber doors?
Yes. We service Rytec, Hörmann SpeedLine, TNR/Albany, and all major high-speed door systems. Common repairs include curtain replacements, crash resets, motor and VFD service, and safety edge replacements.
Are your technicians certified for working at heights?
Yes. All Wilcox technicians are certified under Ontario’s Working at Heights regulation (O. Reg. 213/91). We maintain full WSIB coverage and CGL insurance on every job.
How do you handle repairs in live operational environments?
We complete a JHA before any work begins, apply lockout/tagout on all powered systems, and coordinate with your facility team. We work evenings, nights, and weekends to avoid peak production hours.
Do you provide repairs for cold storage and freezer door systems?
Yes. We repair insulated sectional doors, high-speed rubber doors, walk-in cooler impact doors, and bi-parting cold storage doors. We understand the performance requirements for sub-zero environments.
What is the difference between a dock leveler repair and replacement?
Repair is warranted when the core structure is sound and the failure is in a serviceable component. Replacement is needed when the deck is warped or the unit is 15–20+ years old with multiple failing systems. We give you an honest assessment and quote both options.
Can Wilcox service our facility across multiple Ontario locations?
Absolutely. We manage multi-location contracts for retailers, 3PLs, food manufacturers, and property managers. One service agreement, one point of contact, consolidated invoicing across all sites.
What areas of Ontario do you service?
We cover all of Southern Ontario — GTA, Golden Horseshoe, and beyond. Our regional dispatch keeps response times fast across Mississauga, Toronto, Brampton, Hamilton, Kitchener, Barrie, and surrounding areas.
Do you perform fire door inspections separately from drop testing?
Yes. We perform full NFPA 80 visual inspections as a standalone service — useful for new facility takeovers, pre-acquisition due diligence, and insurance audits. We identify all deficiencies and deliver documentation acceptable to your AHJ.
