Houses within sight of the water take a constant salt load. It is invisible until it dulls glass, powders paint edges and holds moisture against render long after the rain has stopped.
Glass and frames
Salt film re-forms on seaward glass within days of a clean, which is why coastal window rounds are often shorter than inland ones. Pure water rinsing lifts salt without leaving a residue that attracts more.
This guide sits under our Wall Cleaning & Softwash work, covering 20-mile radius of Plymouth.
Render and paint
Salt is hygroscopic - it holds water. Damp render stays biologically active for longer, so seaward elevations go green faster than the sheltered side of the same house.
Practical cycles
We usually suggest a shorter interval on the exposed elevation only, rather than treating the whole property more often. It costs less and matches how the building actually weathers.
Questions we get on this
- Do you clean properties right on the front?
- Yes, across Plymouth, the Sound and surrounding coastal villages within our working radius.
- Does salt shorten how long results last?
- On the exposed elevation, usually yes. We build that into the advice rather than the price.
- Can salt be removed from render permanently?
- No - it is continually redeposited. The goal is managing the growth it encourages.
