Hi All, I have shiplap on the front and rear of my semi detached house and I'm not sure when it needs treating. It looks a bit grey in one corner but otherwise is still the brown colour the same as the rest of the houses here. We've been here for a year but I have put off treating it because it is awkward at the rear because the previous owners put a conservatory along the whole back of the house. It's impossible to reach the walls from upstairs windows as the large ones don't open and the conservatory roof is the thick but hollow square tubular sort of sheets which I'm not sure would take a mans weight.
Should I get a builder in with scaffolding to do the treating? If so would it be a good idea to get plastic shiplap put up instead and save in the longrun?
Any advice would be gratefully recieved
