Wayne County · on Lake St. Clair

Pressure Washing in Grosse Pointe, MI

The five Pointes sit on the lake in eastern Wayne County. Tudor Revival, neo-Georgian, Dutch Colonial and arts and crafts houses, most of them older, most of them masonry, under mature trees a block or two from open water. That combination grows moss and algae faster than anywhere else on our map, and it is the least forgiving of a pressure wand.

What we actually find on Grosse Pointe properties

Every town on our map has its own housing stock, its own weather exposure and its own list of things that go wrong on the outside of a building. This is Grosse Pointe.

01

Pre war brick and limestone will not take pressure

Mortar in a house built before the war is softer than the brick around it. A wand at full pressure washes the joints out and the repoint bill is a different order of magnitude from the wash. Everything here is soft wash: low pressure, the right detergent, time, and a rinse.

Under old trees a roof grows moss, not just algae

Algae is a black stain. Moss is a plant with a root in the shingle, and it holds water against the mat until the mat fails. Pulling it off dry takes the granules with it. We treat it, let it release, and rinse at low pressure so the shingle survives the cleaning.

Divided light windows are hand work

An original window has eight or twelve small panes to a sash and painted muntins between them. That is not a job for a wand at any pressure. It is a pole, pure water and a hand finish on the sills, and it takes the time it takes.

A block from the lake, nothing ever dries all the way

Humidity coming off Lake St. Clair keeps the shaded side of a house damp through most of the season. It is why the Pointes need washing on a shorter cycle than inland Macomb County, and why skipping a year here costs more than it saves.

“Scott was very responsive and helpful in answering questions ... I can’t wait to see the roof clear if all moss and growth. I also had my siding soft washed. Would consider doing this yearly to hopefully prolong the life of the roof I have and clean the siding. 100% recommend.”
