Due to the nature of the materials upstands are made from, usually MDF
We can only cut the mitres & edge the ends
Only a small amount of water will cause damage.
As a result the joints & sealing against water damage is left to the client
If we are asked, & agree to do it we cannot be held responsible
if water damage results.
Every care is exercised to ensure a good seal but the volume of water
in the vicinity of the upstands is beyond our control.

Please read the manufacturers leaflet carefully.
