What Our Customers Say
FAQ – Composite Decking Supplier for Markham
What makes National Decking a trusted composite decking supplier for Markham?
National Decking supplies premium composite decking materials for Markham homeowners, contractors, and deck builders. We help customers compare brands, colours, profiles, board lengths, fascia, fasteners, railings, and accessories so they can order the right materials for their deck project. Our team works with decking products every day and can guide you based on Ontario weather, project size, budget, and installation needs.
Which composite decking brands do you supply for Markham projects?
We supply trusted composite decking brands such as Trex, TimberTech, Fiberon, and TruNorth. Availability may vary by collection, colour, profile, and board length, so we recommend checking current stock before placing your order. We can also help compare the main differences between each brand.
Is composite decking suitable for Markham’s freeze-thaw weather?
Yes. Composite decking is a strong choice for Markham’s Ontario climate because it is designed to handle moisture, seasonal temperature changes, UV exposure, and regular outdoor use better than traditional wood decking. It does not require annual staining or sealing, making it a practical low-maintenance option for backyards, patios, and contractor-built decks.
Do you deliver composite decking to Markham and nearby areas?
Yes. National Decking supplies and delivers composite decking to Markham, Unionville, Thornhill, Cornell, Buttonville, Milliken, Greensborough, Berczy, Wismer, Richmond Hill, Vaughan, Stouffville, and nearby GTA areas. Delivery timing depends on product availability, order size, and location.
Can Markham contractors and deck builders get special pricing?
Yes. Contractors and deck builders working in Markham can contact National Decking for contractor pricing, bulk material support, and product availability. We can help with composite boards, fascia, fasteners, railings, lighting, and other deck materials needed for residential or commercial projects.
Can I visit a showroom before choosing composite decking for my Markham project?
Yes. You can visit a showroom to compare composite decking samples, colours, textures, profiles, and brands before ordering. This is useful for homeowners who want to see the material in person and for contractors who need to confirm the right product before quoting or building a deck.
Can I order fascia, hidden fasteners, railings, and lighting with my decking?
Yes. In addition to composite decking boards, you can order matching fascia, hidden fasteners, railings, lighting, and other deck accessories. Buying the full deck package together helps avoid delays and makes it easier to match materials correctly.
How do I choose between composite decking and PVC decking for a Markham project?
Composite decking is a strong low-maintenance option for most Markham backyard decks and offers a good balance of durability, appearance, and value. PVC decking is usually a more premium option and can be better for areas with higher moisture exposure or customers who want a lighter-weight synthetic board. The best choice depends on your budget, design, exposure, and long-term performance expectations.
