Waterproof. Durable. Built for Every Alberta Season.
Vinyl decking is the only decking surface that is completely and permanently waterproof. Unlike composite, PVC boards, wood, or any other deck surface category, vinyl decking is a membrane system — it is heat-welded at every seam and edge to create a continuous, water-impermeable surface that protects the structure underneath. For homeowners with elevated decks above living spaces, garages, or lower-level patios, vinyl decking is often the only logical choice — and for many others, it is simply the best long-term low-maintenance surface available.
At Green Ladder Contractors, we install vinyl decking systems across Red Deer and Central Alberta. We help homeowners select the right product for their deck structure, exposure, and aesthetic goals — and we install every membrane with the workmanship standards required to keep the warranty intact and the deck performing properly through Alberta's full range of seasonal conditions.
What Is Vinyl Decking?
Vinyl decking is a PVC sheet membrane — typically 45–65 mils thick — that is applied directly over a solid plywood deck substrate. It is reinforced with a polyester or non-woven backing for dimensional strength, and it comes in rolls ranging from 54" to 72" wide in a variety of patterns, colours, and textures.
The key difference between vinyl decking and every other decking material is how it handles water. Rather than simply resisting moisture at the board surface, vinyl creates a fully sealed membrane. All seams are heat-welded on-site, all edges are sealed and metal-capped, and all penetrations (drains, posts, ledger boards) are properly flashed and sealed. The result is a deck surface that directs all water off the surface — not through it.
This makes vinyl decking the definitive choice for:
-
Elevated decks over garages, basements, or living spaces where water penetration would cause damage
-
Balconies and roof decks
-
Pool decks and waterfront applications
-
Any homeowner who wants a sealed, low-maintenance surface that will never need staining, sealing, or sanding
Vinyl vs Other Decking Materials
Feature | Vinyl Decking | Composite/PVC Boards | Pressure-Treated Wood |
|---|---|---|---|
Warranty | 10–15 years waterproofing | 25–50 years product | Maintenance-dependent |
Installation | Applied membrane over plywood substrate | Boards fastened to structural framing | Boards fastened to structural framing |
Repair | Damaged sections can be patched | Boards replaced individually | Boards replaced individually |
Appearance | Wide range of patterns, textures, and colours | Very realistic wood looks | Natural wood |
Maintenance | Annual inspection + occasional cleaning | Occasional | Staining every 2–4 years |
Best for over living space | Yes — specifically designed for this | No | No |
Waterproofing | 100% waterproof membrane — no water penetrates | Water resistant — boards shed water, gaps allow some through | Requires staining; wood absorbs and passes moisture |
Vinyl Decking Is a Different Category
One important distinction homeowners should understand: vinyl decking is a surface membrane applied over a solid plywood deck, not individual boards fastened to an open-joist frame. This means the structural approach is different from composite or wood decking. The deck substrate must be solid, level, and properly supported before the vinyl is applied. Green Ladder Contractors handles the full build — structural framing, plywood substrate, and vinyl membrane installation — as one integrated system.
Patterns, Colours & Styles
Vinyl decking has come a long way from the plain grey or beige membranes of previous generations. Today's vinyl comes in a wide range of patterns and textures including:
-
Wood grain patterns — Realistic plank and board-style looks that mimic hardwood or cedar
-
Contemporary wood — Modern flooring-style patterns that extend your indoor aesthetic outdoors
-
Concrete and stone patterns — Clean, architectural looks that suit modern home designs
-
Solid and textured finishes — Classic, clean surfaces in a range of neutral and earth tones
Colours and patterns vary by manufacturer. During your free consultation, Green Ladder Contractors can walk you through available options and help you match the surface to your home's exterior.
Maintenance and Lifespan
Vinyl decking is one of the lowest-maintenance deck surfaces available — but it is not zero-maintenance. To protect your warranty and maximize lifespan, vinyl decks require:
-
Annual inspection of all seams, edges, metal cappings, and any sealant or caulking around penetrations
-
Cleaning with mild soap and water as needed — most manufacturers recommend avoiding pressure washers at high settings near seams and edges
-
Prompt attention to any edge or seam lifting — catching minor issues early prevents water from working under the membrane
With proper maintenance and professional installation, a vinyl deck membrane will typically perform for 15–20+ years in Central Alberta's climate. The quality of the installation — particularly seam welding, edge detailing, and penetration flashing — is the single biggest factor in how long a vinyl deck lasts. Green Ladder Contractors installs every membrane to manufacturer specifications to ensure warranty coverage is valid from day one.

Frequently Asked Questions
What is the difference between vinyl decking and composite decking?
Vinyl decking is a PVC sheet membrane applied over a solid plywood substrate — it creates a continuous, fully waterproof surface. Composite decking consists of individual boards fastened to an open-joist frame — it resists moisture at the board surface but is not a sealed waterproofing system. Vinyl is the right choice when waterproofing is required (over garages, living spaces, or basements). Composite is the right choice for open-frame decks where low maintenance and wood aesthetics are the priority.
Is vinyl decking good for Alberta's climate?
Yes — vinyl decking is specifically well-suited to Alberta's climate. The membrane is engineered to remain flexible through freeze-thaw cycling, resist UV degradation at Alberta's latitude, and handle heavy snow loads when the substrate is properly built. Professional installation with correctly detailed edges and seams is essential for performance in extreme seasonal conditions.
How long does vinyl decking last in Alberta?
A professionally installed vinyl deck typically performs for 15–20+ years. The biggest factor in lifespan is installation quality — particularly seam welding, edge detailing, and penetration flashing. Annual inspections to catch any minor seam or edge issues early will protect the membrane and extend its service life.
Can vinyl decking be installed over an existing deck surface?
Sometimes — it depends on the condition of the existing substrate. Vinyl must be applied over a solid, flat, structurally sound plywood surface. If the existing substrate has rot, soft spots, uneven areas, or inadequate structural support, those issues must be addressed first. Green Ladder Contractors assesses the substrate condition during your free site consultation and provides an honest recommendation before any work begins.
Does vinyl decking need to be stained or sealed?
No. Vinyl decking requires no staining, sealing, or sanding — ever. The membrane is the finished surface. Annual inspection of seams, edges, and any caulking or sealant at penetrations is all that's required to maintain performance and warranty coverage.
What causes vinyl decking to fail?
The most common causes of vinyl deck failure are: poor seam welding during installation, inadequate edge and corner detailing, improperly flashed penetrations (posts, drains, ledger boards), and substrate issues that were not corrected before the membrane was applied. This is why choosing an experienced installer who follows manufacturer specifications matters far more with vinyl than with almost any other decking product. Green Ladder Contractors installs every membrane to spec.
Can vinyl decking be repaired if it gets damaged?
Yes. One of the advantages of vinyl membrane systems is that damaged sections can be patched or replaced without replacing the entire deck surface. Repairs must be done properly — heat-welded by an experienced installer — to maintain waterproofing integrity.
