Fabric Replacement
Full membrane recovers for MegaDome and every major fabric building brand — reuse your existing engineered frame and save 50-70% vs new construction.
Built for purpose. Built for Ontario.
Every engineered fabric building eventually reaches the end of its membrane life. PVC and PE membranes are designed for 20-25 years of Ontario service, but UV exposure, repeated snow loading, abrasion and accumulated minor tears compound over time. When the membrane is no longer economical to patch, a full recover is the right move.
A recover is dramatically cheaper than building new. Your existing engineered steel frame, foundation, anchors and most accessory hardware stay in place — only the membrane and worn-out fittings are replaced. Total cost typically lands at 30-45% of new-build pricing, with full manufacturer warranty on the new fabric.
Building Depot is Ontario's authorized MegaDome dealer and the province's specialist in fabric recovers across every major brand. We strip the old membrane, inspect every cable, ratchet, anchor and base-plate, repair or replace any worn hardware, then install fresh PVC fabric tensioned to engineered specification. Optional upgrades — heavier 28 oz fabric, ridge venting, translucent panel additions or insulation systems — are sequenced into the recover at significant cost savings vs. doing them separately.
Most clients keep operating through the recover. We work in sections, isolate the work area, and protect interior contents and equipment. A typical 60'x120' building is back to full operation in 5-10 working days. Every recover comes with stamped Ontario engineering, full membrane warranty and a one-year workmanship guarantee.

ExploreThe complete guide to fabric membrane replacement.
Building Depot is the Authorized MegaDome Dealer for Ontario and fabric membrane replacement services are one of the most-specified MegaDome configurations across the province. Engineered fabric membrane replacement 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.
After 20–25+ years of service, a MegaDome fabric membrane reaches end of design life and is due for full replacement. The hot-dip galvanized steel frame typically still has 25+ years of remaining service life — meaning a membrane replacement effectively delivers a new building at a fraction of the cost of a full new-build. Building Depot performs full membrane replacements across Ontario on MegaDome buildings and on third-party fabric buildings where geometry and frame condition allow.
A typical membrane replacement runs 2–4 weeks depending on building size. The old membrane is decommissioned, the frame is inspected and any required hardware is replaced, and the new OEM MegaDome membrane is tensioned over the existing frame using the original ratchet tensioning system.
This page is the complete Ontario reference for fabric membrane replacement 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.
Headline benefits.
Where MegaDome fits.
End-of-Life Re-Membrane
Full membrane replacement at 20–25+ year service mark. Engineered frame certification and OEM membrane installation.
Storm-Damaged Re-Membrane
Major storm damage requiring full membrane replacement. Engineered insurance documentation supplied.
Third-Party Building Re-Membrane
Re-membrane of non-MegaDome fabric buildings where geometry and frame condition allow.
Frame Upgrade + Re-Membrane
Frame hardware upgrade combined with full re-membrane. Restores building to new-build specification.
Operators we build for across Ontario.
From contract to keys.
Re-membrane projects start with a frame inspection by a Building Depot engineer. The frame is examined for corrosion, distortion, anchor and bracket integrity, and any hardware requiring replacement. The engineer issues a frame certification documenting the building's suitability for re-membrane and the expected remaining service life of the certified frame.
Where the frame inspection identifies major issues — significant corrosion, distortion or anchor failure — Building Depot prepares a frame remediation quote alongside the re-membrane quote. In rare cases the inspection recommends full replacement rather than re-membrane; that recommendation is presented honestly even where it costs us the re-membrane work.
Once the frame is certified, the new OEM MegaDome membrane is ordered to the building's measured geometry. Lead time on new membrane is typically 8–12 weeks from order to delivery in Ontario.
Stamped Ontario engineering on every project.
Every MegaDome fabric membrane replacement 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.

Turnkey installation by Building Depot crews.
On site, the old membrane is decommissioned and removed, the frame and hardware are inspected and replaced where required, and the new membrane is tensioned over the existing frame using the original ratchet system. Most re-membrane projects run 2–4 weeks on site, scheduled into a low-impact window for the operator.
At completion the building receives a fresh 15-year membrane warranty and an engineered re-membrane certificate. The frame retains its original 25-year warranty extended for the certified remaining service life. Operationally the building is identical to a new MegaDome build at roughly 60–70% of the new-build cost.
Backed for the long haul.
MegaDome fabric membrane replacement 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 membrane replacement 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.
