Timber decking in Sheffield
Timber is the traditional choice: warm underfoot, natural to look at and cheaper to fit than composite. It needs a little care each year to keep it at its best.
Treated softwood decking typically costs £60 to £130 per square metre installed, and hardwood £110 to £250.

What a good quote includes
Six things to ask every installer to put in writing, so you can compare quotes properly.
Pressure-treated timber, graded for ground contact
Joists and posts near the ground should be treated to the higher Use Class 4 standard. Ask for it in writing.
Grooved or smooth boards
Grooves are traditional but hold water and dirt. Many installers now recommend smooth or anti-slip boards.
Stainless or coated screws
They resist rust and the black staining that cheap screws leave in timber.
Ventilation under the deck
Air moving under the boards helps the timber dry out, which is what makes it last.
End grain sealed
Cut ends should be treated on site, because that is where rot starts.
A care plan
Ask what treatment the installer recommends and how often, so you know the real running cost.

Is timber or composite better?

How often should timber decking be treated?
