Our flagstone back patio is a mess, a disaster actually. And we’re in quite a quandary about what to do with it, short of a stick of TNT.
There’s moss and algae in the shady corner by the BBQ and where there’s some run off of water from the house.
More problematic is how so many stones have sunk, the ground underneath it fallen in where chipmunks burrow and where over time, the sand has washed away.
You can see here how this stone has nothing underneath it.
The whole patio is a giant trip hazard, so many stones listing and leaning and up and down.
A few years back we lifted up twenty or so stones and filled the ground underneath with a huge delivery of sand we got. It was backbreaking work but the problem now is much worse that much of the patio has resettled.
Here’s the conundrum: As part of the plan to renovate the upstairs, we were going to create a screened in porch off the back of the breakfast room, bring the propane line under the patio to a place for a gas fireplace. We’d clean and refit all the stones, or maybe even change the entire surface to something else, brick, pavers?
Because we opted out of doing the upstairs work last year, if I were to refit/replace the whole stone patio now, it would be money lost when it comes time that we DO finish the upstairs and screen-in part. Capisce?
So, it leaves us with the cheap way out. Get the stones all cleaned (I’ve seen special scrubbers just for flagstone), then have a dump truck of sand delivered and do the least amount of work to make it right for another year.
Pain in the neck. Anyone cleaned their flagstone deck or have someone do it they recommend? The machine I’ve seen is as large as a floor sander, heavy, too heavy for either one of us to use it.
