Treated Timber

Buy Treated Timber Online

Treated timber is used where wood needs extra resistance to damp, rot, and day-to-day exposure. It’s a practical choice for external repairs, outdoor joinery, and any timber work that’s likely to face moisture over time. When you use the right treated timber, it stays more stable, holds fixings better, and reduces the risk of early softening or failure at the ends and cut faces.

Treated timber for outdoor repairs and exposed timber work

Treated timber is commonly used in places that see regular wetting and drying. It’s also used indoors where timber is close to concrete floors, voids, or areas that can stay cold and damp.

Typical uses include:
• external repairs where timber is exposed to rain and condensation
• battens and supports where the timber sits close to masonry
• garden and boundary repairs where timber is outside year-round
• replacement work where you want added protection as standard

What to look for when buying treated timber

Treated timber is still timber, so quality comes down to straightness, consistency, and how you handle it after cutting.

Treatment for the intended exposure
Choose timber treated for the setting it’s going into, especially where the wood will be outdoors or close to persistent damp.

Straight lengths and consistent sections
Bow and twist waste time. More consistent lengths make set-out easier and keep lines straighter.

Cut ends and drilled holes
Any cut face is a weak point if it’s left unprotected. Planning your cuts and sealing exposed ends helps the timber last longer.

Fixing points and splitting control
Treated timber can still split at edges. Pilot holes and sensible edge distances reduce waste and keep fixings cleaner.

Working with treated timber on site

A few habits help treated timber perform better and reduce snagging later.

• store it supported and off the ground so it stays straighter
• avoid trapping water at joints and fixings
• keep cuts clean and avoid tearing fibres at the edge
• use suitable fixings for outdoor use where needed

Before ordering treated timber

• confirm where it’s being used and what exposure it will face
  • choose the section size for the span and load
  • allow for trimming so you’re not forced to use warped ends
  • plan cuts so exposed ends can be protected
  • order enough to keep lengths consistent across the run
