Decks and Landings

Whether you are looking for a classic deck, a beautiful hardwood deck or a low maintenance composite deck, we can create all of these and more. We can even generate a stone tile deck for the same cost as a composite one. Visit our showroom to see what we have to offer!

Wood Maintenance

  • Treated wood should be left for a year before staining: this will help prevent the stain from peeling.
  • If the stain begins to split or crack, sand the deck and then re-stain.
  • We recommend using Sansin brand, Outdoor Wood, Semi-transparent stain. Consult Benjamin Moore for further advice on finishing.
  • If a board warps or cracks, put in a screw to help straighten or hold together the pieces. The entire board can be replaced if necessary.
  • Ensure screws or nails remain below the surface of the decking. If left unattended, screws and nails can become hazardous.

Composite Maintenance

  • Hot grease can melt into composite decking. Please place your barbecue on a mat.
  • Embers from a fire can melt into composite decking. Do not have a wood fire on a composite deck.
  • Composite does not need to be stained but may be if desired.
  • Ensure composite boards remain securely fastened and not broken or cracked.
  • Do not use a high pressure washer on composite decking.
  • Rinse deck with a garden hose every spring and fall. If necessary, soap may be used to clean a composite deck.

Railing Maintenance

  • Make sure the hand rail remains smooth with no cracks or slivers. If the railing is aluminum, make sure there are no gouges or cracks.


  • Greentree provides a 5 year structural warranty against any major structural defects in decks and/or railings.
  • Greentree provides a 1 year workmanship warranty against any craftsmanship defects in decks and/or railing.
  • Composite decking comes with a manufacturer’s warranty.
  • Greentree is not liable for any cracking, chipping, warping, discolouration and/or disfiguration of material that may occur after installation.

Frequently Asked Questions

  • Q: Does composite decking get hot?
    A: The amount of heat that composite decking receives depends on 2 major aspects. Firstly, the amount of sunlight the deck receives, the hotter the material gets. Secondly, the colour of the material can affect how hot the deck gets: lighter colours do not absorb as much heat as darker colours. A deck that receives full sunlight can become too hot to walk on, especially with a darker material.
  • Q: Can composite decking get scratched?
    A: Although composite decking is “scratch resistant,” it is not scratch proof therefore your decking can be scratched. However, it does take more force to scratch than pressure treated or cedar decking.
  • Q: Does composite decking colour fade?
    A: Most composite decking comes with a warranty against fading for between 20 to 25 years.
  • Q: Is there a tolerance for gaps?
    A: Due to the expansion and contraction of the boards at different temperatures, the spacing at joints will fluctuate.
  • Q: Is composite decking slippery?
    A: This can be greatly different between material types. Some materials, like Zuri, are fairly smooth whereas other matierials, like Trex, are fairly rough. The smoother materials can become slightly slippery when wet and especially slippery when frosted. The more rough materials grip well when wet but can be slightly slippery when frosted.
  • Q: Do I have to stain cedar wood?
    A: You do not have to stain cedar wood as it has natural oils that help protect it from the climate. Cedar will fade to a gray over time unless you stain it; if you do stain it however you may need to do so every year.
  • Q: Do I have to stain pressure treated wood?
    A: It is not recommended to stain pressure treated lumber for a minimum of 1 year as it has been recently coated in a treatment paint that can inhibit the ability of the stain to adhere to the wood. However, as it dries out staining pressure, treated wood is recommended to increase the lifespan. We recommend using Sansin brand, Outdoor Wood, Semi-transparent stain. Consult Benjamin Moore for further advice on finishings.
  • Q: What kind of fasteners will my deck have?
    A: Composite decking has hidden clip fasteners in the central portion and mushroom head screws on the borders, sides and detail work. Cedar and pressure treated decking use standard treated deck screws on their decks, side skirts and railings. The structure of all decks use nails rather than screws as nails have a higher shear strength.
  • Q: What kind of piles will my deck have?
    A: As a standard, we use screw piles on all decks however this may change to fit your local building codes.
  • Q: What is the underside of a deck made of?
    A: All our deck structures are built with pressure treated lumber, in adherence to the City of Edmonton code.
  • Q: Do I have to get a permit for my deck?
    A: We recommend contacting your local building authority to determine which, if any, permits may be required. If requested, your project manager can help to acquire the permit on your behalf.
  • Q: Will all my steps be the same height?
    A: All of your steps will be within ¼” of each other, aside from the step that meets the ground, as the ground may be uneven.
