Pressure washing in St. Clair Shores, MI and Metro Detroit: Your pavers are still under there.

Yes. HD Landscape is based in St. Clair Shores and pressure washes walks, patios and pavers here and across Metro Detroit. Call or text (586) 718-8762 to set up a free estimate.

Walks, patios and pavers. For anything else, such as a driveway, send a photo first so Jake can see whether it is a job we can take on.

It can if it is done badly. A narrow tip held close can blow out joint sand, and too much pressure can mark softer surfaces. Done well, a wash starts on a small spot and stays a wide spray at a low angle that does not run down the joints.

There is no single number, because the surface decides it. The Concrete Masonry and Hardscapes Association lists 1,000 to 4,000 psi for professional cleaning of concrete pavers, while the Brick Industry Association says no more than 400 psi on clay brick unless the maker allows more. The safe way in is to start low with a wide fan tip and go up only if a small spot shows the surface can take it.

Often, yes, at least a little. Even careful washing can move some joint sand, so look at the joints once the surface is dry. If the sand has only dropped a bit, a top up may do it. If the joints are weedy or keep washing out, polymeric sand may be the better fix.

It is probably efflorescence, natural salts that moisture carries to the surface and leaves behind as it dries. It does not hurt the pavers and it tends to fade with time. Pressure alone will not cure it. If you would rather not wait, it takes a cleaner made for the job, tried on a small spot first.

Shade and moisture. Moss and algae settle in where paving stays damp, often on the shady side of a house, under trees or where a downspout lets out. Washing removes the growth, but the spot will go green again if it stays wet. Jake can point out what is keeping it damp, and if the problem is drainage, yard grading may help.

Only when it needs it. Regular sweeping keeps most paving clean, and washing more than you have to wears on the joint sand. A good time to call is when a broom and a hose have stopped working.

Spring is the natural time, because a yearly look over of your pavers belongs in the spring anyway, and a wash clears off what winter left behind. Fall is a chance to deal with leaf stains before the cold. Wait until temperatures are safely above freezing, since a wet surface can turn to ice. It pairs well with a spring or fall cleanup.

Sometimes. Oil soaks in, so water alone may only lighten it, and deep stains can take repeated treatment. Plan on lighter, not always gone. A photo of the stain is a good start, and Jake can give you a straight answer from there.

Dirty wash water should stay out of storm drains, because storm drains generally lead to lakes and streams, and around here that can mean Lake St. Clair. So the runoff needs thought before the water goes on, and plain water is the first choice. If you are washing on your own, ask your city what it allows, because local rules vary.

That comes down to how much surface there is, what is on it and how the joints look, so Jake prices it once he has seen it. A photo by text is a fine start. Seeing it is free, and you end up with an itemized estimate you can go through line by line.
