A deck in Niskayuna spends five months under snow and ice and the rest of the year under pollen, tree sap, and shade. What starts as a light gray film turns into slick green mildew on the north side and black tannin blotches wherever wet leaves sat over the winter.
Deep tree canopy along River Rd and Rosendale keeps hardscape damp for days, so green algae film and joint moss are the number-one complaint here.
We clean decks the way the wood and the composite manufacturers say to: a dedicated cleaner, real dwell time, and low pressure — never a turbo tip dragged across the grain. The result is an even, bright surface that's ready to seal or ready to use.
