Fabric Building Maintenance
Annual inspections, tensioning, hardware service and preventative maintenance plans that protect your fabric building investment for decades.
Built for purpose. Built for Ontario.
An engineered fabric building is a 25-40 year asset, but only if it's maintained. Membrane wear, cable creep, hardware fatigue and drainage drift are all predictable, manageable conditions — when caught early, none of them become structural problems. When ignored, they cascade into membrane failure and tens of thousands of dollars in damage.
Building Depot's preventative maintenance program is built around what MegaDome engineering and decades of Ontario installation data tell us a fabric building actually needs: an annual structural and tensioning inspection, a spring drainage and ground-condition review, and a late-fall snow-readiness check before the first major loading event of winter.
Every maintenance visit includes cable and ratchet tensioning to spec, hardware torque verification, membrane abrasion and tear inspection, anchor and base-plate corrosion review, drainage and ground-line trim audit, plus full mechanical service on roll-up doors, sliding doors and ventilation hardware. You receive a written condition report with photos and a prioritized action list.
For owners who want predictable budgeting and priority response, we offer one-, three- and five-year service agreements. Agreement clients receive locked-in maintenance pricing, after-hours emergency mobilization, and free annual drone photography of the building exterior for insurance and asset-record purposes.

ExploreThe complete guide to fabric building maintenance.
Building Depot is the Authorized MegaDome Dealer for Ontario and fabric building maintenance services are one of the most-specified MegaDome configurations across the province. Engineered fabric building maintenance services combine a hot-dip galvanized steel arch frame with a high-tenacity PVC membrane to deliver a clear-span, naturally lit, corrosion-resistant envelope that lasts decades with a fraction of the operating cost of conventional steel or wood construction.
MegaDome fabric buildings are engineered for minimal maintenance — annual inspection, periodic re-tensioning, and routine cleaning of ridge vents and louvers. Building Depot offers Ontario-wide annual maintenance contracts that keep owners in warranty-compliant condition and identify potential issues before they become structural failures.
A typical annual maintenance visit takes a half-day per building. At the 5–7 year mark we perform a full re-tension of the membrane to compensate for the natural relaxation that occurs in any PVC fabric structure. With that simple maintenance cycle, MegaDome buildings routinely deliver 25–30+ years of service before fabric replacement is required.
This page is the complete Ontario reference for fabric building maintenance services — covering benefits, applications, construction process, engineering, foundation options, installation, warranty and ongoing maintenance. Every Building Depot project is delivered turnkey under one accountable contract: in-house engineering, stamped Ontario drawings, municipal permit management, foundation construction, fabric installation and full commissioning. One contract, one project manager, one phone number from kickoff to keys.

Operators we build for across Ontario.
From contract to keys.
Annual maintenance contracts are scheduled into the off-season window for each application — fall for agricultural operations, spring for sport facilities, summer for ice arenas. A Building Depot maintenance technician arrives with a documented inspection checklist and the tools, hardware and small-quantity membrane patches required for routine fixes.
Inspection covers the full membrane surface, ratchet tensioning system, anchor bolts, ridge vent and gable louvers, end-wall doors, and the foundation interface. Findings are documented with photographs and tabulated in an engineered inspection report delivered within 5 business days of the visit.
Where the inspection identifies a major issue (membrane damage beyond patching scope, structural settlement, hardware failure beyond routine replacement), a separate repair quote is prepared and the work is scheduled as a follow-up service visit.
Stamped Ontario engineering on every project.
Every MegaDome fabric building maintenance services Building Depot delivers in Ontario ships with third-party engineering sealed by an Ontario P.Eng. and certified to CSA A660 — the Canadian standard for pre-engineered steel building systems. Engineering accounts for site-specific snow loads (1.6–3.5 kPa across the province), hourly wind pressures per the Ontario Building Code, unbalanced snow drift conditions and any seismic factors. Drawings include the full structural design, foundation reactions, anchor bolt schedules and ventilation specifications, and are submitted directly into the municipal permit package.
Engineering is included in every Building Depot quote — never billed separately, never outsourced to a third party the owner has to chase. The same engineering team that designs the building stands behind it through the permit process, the foundation inspection and any post-construction follow-up. That single accountable contract is why GTA developers, Northern Ontario mining operators and Eastern Ontario municipalities specify MegaDome through Building Depot as their default fabric building solution.
Engineered to your site, your budget and your soil.
Anchor Bolt Inspection
Annual inspection and re-tightening of perimeter anchor bolts. Standard part of every annual visit.
Foundation Crack Survey
Annual foundation crack survey. Identifies settlement and freeze-thaw movement before structural impact.
Curb Wall Re-Caulk
5-year re-caulking of base channel and curb wall interface. Maintains weather seal.
L-Block Position Survey
Annual position survey of pre-cast L-blocks. Identifies movement from loader impact or settlement.
Turnkey installation by Building Depot crews.
All maintenance work is performed by Building Depot's in-house service crews using OEM MegaDome parts. There is no sub-contracting to third-party crews unfamiliar with the tensioning system. Routine maintenance includes membrane re-tensioning to manufacturer specification, anchor bolt re-torquing, hardware replacement and ridge vent / louver cleaning.
At the 5–7 year service mark, a full membrane re-tension is performed across the entire envelope. This single intervention extends the membrane's effective service life by 5+ years and is the most cost-effective maintenance investment an owner can make on a MegaDome building.
Backed for the long haul.
MegaDome fabric building maintenance services carry a 25-year limited warranty on the structural steel frame and a 15-year limited warranty on the PVC membrane. Both warranties cover materials and workmanship and are honoured directly by Building Depot — Ontario's Authorized MegaDome Dealer — so warranty claims are resolved by the same team that installed the building, not bounced between a dealer, a manufacturer and a sub-contracted installer.
Hardware components — ratchet tensioners, anchor brackets, ventilation louvers and door systems — are covered under the membrane warranty. Building Depot maintains a full inventory of replacement membrane panels, brackets and hardware in Ontario, which means warranty service is typically scheduled within days, not the weeks it takes a U.S.-based supplier to ship parts across the border.
Simple, predictable upkeep.
Maintenance on a MegaDome fabric building maintenance services is intentionally minimal — that's a core part of the value proposition versus conventional steel. Annual maintenance comprises a visual inspection of the membrane surface and ratchet tensioning system, a check of ridge vents and gable louvers, a tightening of anchor bolts where exposed and a wash-down of any accumulated debris. The hot-dip galvanized steel frame requires no painting, no rust treatment and no panel replacement over the building's design life, which is a meaningful operating-cost advantage over painted metal buildings that demand recoating every 10–15 years.
Building Depot offers an Ontario-wide annual inspection and re-tensioning service for operators who want a turnkey maintenance contract. A typical building requires a half-day visit once a year to remain in warranty-compliant condition. At the 5–7 year mark, our crews perform a full re-tension of the membrane to compensate for the natural relaxation that occurs in any PVC fabric structure. With that simple maintenance cycle, MegaDome buildings routinely deliver 25–30+ years of service before any fabric replacement is required.
