Frequently Asked Questions

  • Pressure-treated lumber generally lasts anywhere from 15 to 40 years, depending on the treatment level, the exposure, and whether it is in contact with the ground. Material rated for ground contact holds up longest, which is why it is used for posts, docks, and structural framing. Keeping it sealed or stained and off standing water helps it reach the upper end of that range. We stock the right grades for decks, docks, and outdoor framing.

  • Both are excellent outdoors, and many builds use them together. Pressure-treated lumber is stronger and more economical, which makes it the go-to for structure, framing, and anything in ground contact. Cedar is naturally resistant to rot and insects and simply looks better, so it is a favourite for exposed finish work like decking, railings, and trim. Tell us your project and we will help you decide where each one fits.

  • New pressure-treated lumber usually needs to dry out before it will accept stain, and that can take anywhere from a few weeks to a few months depending on the weather. A simple test is to sprinkle water on the surface: if it beads up, the wood is not ready, and if it soaks in, you are good to stain. Staining too early traps moisture and the finish will not hold. We can recommend the right stain once your lumber has dried.
