About This Water Blasting Job
There was nothing broken at this house. That is exactly why jobs like this sit on the list for years — no single part of it is urgent, and all of it is annoying every day.
The first area was a quiet corner at the back with a bench. It had gone green all over: the pavers, the timber seat and the fence behind it. Moss does not stay cosmetic for long — it holds water, so the pavers were genuinely slippery after rain, and sitting there came with a faint smell of damp. Washed back, it is somewhere you would use again.
One honest note about that corner. The fence had been painted, and in places the paint had already lifted where the moss had been working away underneath it. Water blasting took some of that loose paint off with the moss. That is not damage, it is paint that was coming anyway — but it does mean a return visit the next day to touch the fence up, which is worth knowing before you book a wash on painted timber.
The second area was the BBQ space in front of the brick fireplace. Years of organic matter walked across the concrete had gone green, and on top of that there were paint marks left behind by earlier work around the house. For this one the concrete attachment came out — a rotary surface cleaner made for slabs. It spins its jets under a shroud, so the pressure lands evenly instead of cutting stripes into the surface, and the spray stays under the hood instead of going up the fireplace and over the furniture. It lifted the moss and the old paint together.
The third was the entrance: a few pavers and a section of driveway at the front door. Small, but it is the first thing anyone sees.
Three areas, about two hours, $220 for the water blasting, done on my own.
