When we handle commercial pressure washing for concrete in New Hampshire, it comes down to three things: protecting your plants and property, cleaning with the right method, and walking the job with you at the end. On concrete, the method we use is pressure wash with a surface cleaner.
Method and pressure
Cleaning solution: A degreaser for oil spots and a pre-treatment for organic growth; post-treatment slows regrowth.
Cleaning concrete safely
Plain broom-finish concrete is the surface pressure washing is made for. A rotary surface cleaner gives an even finish without the stripes a wand leaves, and hot water helps with grease and oil.
Avoid: Holding a narrow tip close to the surface, which etches lines into the cream layer of the concrete.
How often: Every year, or every 6 months in shaded, damp spots.

Local commercial pressure washing for concrete for New Hampshire
Commercial properties in New Hampshire usually get a big spring clean of sidewalks, entrances and parking areas to remove sand, salt and winter litter, and many schedule a second visit in the fall.
Near the coast, salt air leaves a film on siding, windows, screens and railings that dulls finishes and speeds up corrosion on metal. Regular rinsing and washing help protect them.

Every year, or every 6 months in shaded, damp spots. Shade, nearby trees, humidity and heavy traffic mean more frequent cleaning; sunny, dry spots can go longer. Our free cleaning frequency tool gives a recommendation for your climate.
What if it rains on the day?
