Frequently Asked Questions — Commercial Door & Dock Installation
Common questions from contractors, facility managers, and operations teams planning new door and dock installations across Ontario.
How do I know what type of commercial door is right for my facility?+
It depends on your traffic volume, clear opening height, thermal requirements, operating environment, and security needs. High-traffic facilities like distribution centres and food processing plants benefit from high-speed roll-up doors. Cold storage and freezer applications require insulated sectional or insulated roll-up doors. Fire-rated openings require listed fire door assemblies. Security-sensitive openings often use rolling steel. Wilcox does a full site assessment before recommending any product — we'll match the door to your actual operating conditions, not just sell you what's easiest to stock.
What loading dock equipment do you install?+
We install the complete range of dock equipment: hydraulic, air-powered, and mechanical dock levelers; edge-of-dock levelers; vertical-storing levelers; dock seals (foam and inflatable); dock shelters; dock bumpers; hook-style and wheel-based vehicle restraints; interlock control panels; dock lifts and scissor lifts; dock lighting and fans; traffic light systems; and dock conversion kits. We work with all major manufacturers and can match your existing equipment for consistency across your facility.
How long does a commercial door or dock system installation take?+
A standard overhead sectional door or dock leveler replacement typically takes 4–8 hours. A full dock package (door, leveler, seal, restraint, and interlock) typically takes 1–2 days. New construction multi-door projects are scheduled in phases and detailed timelines are provided during the quote stage. We coordinate with your operations team to minimize downtime and can work nights and weekends for facilities that can't take daytime outages.
Do you work with general contractors on construction projects?+
Yes. Wilcox is an experienced trade subcontractor for commercial and industrial construction projects across Ontario. We provide shop drawings and equipment submittals, attend site coordination meetings, work directly with structural and mechanical trades, and meet milestone schedules. We've worked with major construction firms including EllisDon on large-scale new construction and renovation projects. We can take a single door or a 40-door project.
Do you handle building permits for door and dock installations?+
Yes. Our project management team coordinates the permit process for installations requiring building permit review — including fire-rated door assemblies, new structural openings, and new construction projects. We work directly with the general contractor and local building department to keep your project on schedule. For straightforward replacements in existing rough openings, a permit is typically not required.
Do you install fire-rated door assemblies?+
Yes. Wilcox installs and certifies fire-rated door assemblies including rolling steel fire doors, fire shutters, and fire-rated sectional doors per NFPA 80 and Ontario Fire Code requirements. We work with listed assemblies from all major manufacturers and ensure the complete installation — door, frame, hardware, fusible link, and automatic closing device — meets the specified fire rating. We provide full documentation for your AHJ, insurer, and building inspector at project sign-off.
What brands of doors and dock equipment do you install?+
We are vendor-neutral and install products from all major manufacturers. For doors: Hörmann, Rytec, Cornell, Cookson, CHI Overhead Doors, Wayne Dalton, Raynor, and ASSA ABLOY. For dock equipment: Blue Giant, Poweramp, Rite-Hite, Pentalift, and others. We'll recommend the right product for your budget, application, and serviceability — not just the brand we happen to stock.
Can you replace a dock leveler without modifying the pit?+
In most cases, yes. We perform a site assessment to measure the existing pit dimensions and spec the right replacement unit or closest-fit option. When minor pit modifications are needed — concrete work, dock board adjustments, or steel modifications — we handle that in-house or through our trusted civil partners. We'll quote the full scope so there are no surprises.
What is included in the turnover package at project completion?+
Every completed Wilcox installation includes a comprehensive digital turnover package: manufacturer product warranty documentation, Wilcox workmanship warranty, as-built installation records, operating and maintenance manuals, high-resolution photos of the completed installation, and a list of all equipment installed with model and serial numbers. For dock systems, we also provide on-site operator training for your team on safe and correct use of levelers, restraints, and interlock controls.
Do you install vehicle restraints and dock safety interlock systems?+
Yes. Dock safety systems are a core part of our installation work. We install hook-style and wheel-based vehicle restraints, manual restraints, interlock control panels, dock communication lights, fans, bumpers, and safety signage. Critically, we commission and test the complete interlock sequence — so the restraint, leveler, and overhead door are properly interconnected and your dock meets OHSA loading dock safety requirements from day one.
How do you handle installation at live facilities without disrupting operations?+
We are very experienced working in live operational environments: active distribution centres, food processing plants, cold storage facilities, pharmaceutical warehouses, and retail logistics hubs. We coordinate staging areas, access windows, and work phases with your facility team. For critical docks that can't go offline during business hours, we schedule installation work in the evening or overnight. Our crews are disciplined and efficient — we've done this on complex live sites hundreds of times.
Do you provide a warranty on installation work?+
Yes. All Wilcox installations are backed by the manufacturer's product warranty and our own workmanship warranty. Specific warranty terms vary by product and manufacturer — these are detailed in your quote. We also offer extended service and maintenance agreements to keep your equipment covered and performing well beyond the initial warranty period.
Can you install doors and dock systems across multiple locations for a national account?+
Yes. Wilcox operates nationally and manages multi-site installation programs for retailers, 3PL operators, food manufacturers, and industrial real estate portfolios. We provide a single project management point of contact, consolidated scheduling, and unified reporting — so your national facilities program runs on one set of standards regardless of location.
What is the difference between a sectional door and a rolling steel door?+
Sectional doors are constructed of horizontal panels connected by hinges and travel up and back along overhead tracks. They are the most common commercial door type, offering good insulation, variety in sizes and finishes, and easy operator integration. Rolling steel doors coil into a compact overhead drum and are preferred for high-security or space-constrained applications — particularly where ceiling clearance above the opening is limited. Rolling steel doors are also available in fire-rated configurations. Wilcox installs and services both types.
