Get matched with top pressure washers in Cornwall, NY

We don’t recommend pressuring washing clapboard siding. At high levels of pressure, a pressure washer can damage wood siding permanently. Pressure washing can also make it easier to drive water into the cracks of clapboard (which are recommended for easier drainage), causing moisture damage.

If you think your clapboard siding is so dirty it could benefit from pressure washing, we suggest contacting a pressure wash cleaning service and getting a quote on a wood siding project. Some siding manufacturers recommend never pressure washing because it can force water behind the siding.

Does the water in your taps sometimes come out very slowly? If so, you might have problems with low water pressure in your house, and your pressure washer won’t effectively clean. To test if your water pressure is sufficient, time how long it takes for the water from your hose to fill a 5-gallon bucket. Usually, if it takes less than two minutes, you’re good to go.

You should avoid using a pressure washer on any surface or item that could be damaged by the high-pressure spray, as some materials are too delicate to withstand the force.

Key items and surfaces to avoid include:

• Electrical Components: Never pressure wash electrical systems, as water can cause short-circuits and create a safety hazard. This includes utility meters, breaker boxes, electrical outlets, generators, and HVAC or air conditioner units.

• Delicate and Fragile Materials: Fragile items can crack, shatter, or be stripped by the pressure. Avoid pressure washing windows, glass, light fixtures, shingled roofs (especially asphalt), and stucco.

• Painted, Stained, or Sealed Surfaces: Unless your goal is to strip the finish, do not pressure wash painted surfaces, stained wood (like decks), or anything with a protective seal that could be stripped away. Be especially cautious with older surfaces that may contain lead paint.

• Soft Woods and Certain Decking: Delicate surfaces like softwood, composite decking, and antique or wooden patio furniture can be etched or damaged. If you must wash wood, use a lower-powered pressure washer with a wide-angle nozzle to prevent damage.

• Living Things: Never use a pressure washer on people, pets, or plants. The force can cause serious injury and will destroy landscaping.

Generally 1-2 hours, depending on the area and level of dirt accumulation.
