Pro Power-washing Tips
Getting your house in tip-top shape for the warm season often means blasting away crud with a power-washer. Keep reading for the dirt on how to tackle four common tasks
Get a Deck Summer-Ready
Opt for a 40-degree fan nozzle and keep it at least 6 to 8 inches from the boards. For optimum control, spray at a 45-degree angle, starting close to the house and slowly working away from it. Spray boards in the direction of the grain.
Loosen Filth from a Fence
For fences, including composite ones, start at the top and work your way down with a 40-degree fan nozzle. Think twice before spraying wood lattice; its thin strips are delicate and typically held together with galvanized staples, so excessive pressure can tear panels apart.
Shape Up Your Siding
Less pressure will get this job done. Use a 25-degree nozzle to fan the water out evenly, and work with the tip of the wand 12 to 18 inches from the house. Spray at a downward angle in the direction of the siding laps. Spraying head-on can force water behind the siding, and into the sheathing, causing damage and ruining wall insulation—ditto for shingle siding.
Remove Grime from a Roof
Washing asphalt shingles under excessive pressure can loosen the textured granules that make up its protective coating, leaving your home susceptible to water damage during the next rainstorm. This cleaning job is best left to an insured pro.
