Why composite for slopes
A hillside deck often means many steps and several levels. Timber steps can become slippery in shade and need treating every year, which is a chore when parts are awkward to reach. Capped composite stays grippy and needs only an occasional wash.
Steps and nosings
Composite ranges include step treads, risers and nosings in the same colours. A contrasting nosing on each tread makes steps easier to see, which matters on long flights.
Fitting on a slope
Composite needs closely spaced joists and a level frame. On terraced decks each level gets its own frame on concrete pads, with joists set accurately so boards sit flat and the hidden clips hold properly.
Frost and shade
Durham winters bring frosts, and hillside gardens can stay shaded. Capped boards resist moisture, so freeze-thaw doesn't damage them the way it can split timber. They also resist the green film that makes shaded timber slippery.
Colour
Mid-greys and browns suit both Durham's sandstone and brick houses, and hide dirt on busy steps. We bring samples to the survey.
Maintenance
A brush and an occasional wash with soapy water keeps composite clean. On a hillside deck, that's much easier than treating timber on every step.
FAQ
Can composite be used on a deck with a lot of steps?
Yes. Composite step treads and nosings give a consistent, grippy finish on even long flights.
Does composite cope with hard frosts?
Yes. The capped boards don't absorb water, so they aren't damaged by freeze-thaw. Like any outdoor surface, frost can make them slippery for a while.
