Best pressure washers near Boulder, CO

It takes about 15 minutes per each side of an exterior house to apply detergent and 15 minutes to remove it, so you’ll need roughly two hours for the whole job. However, that length of time may decrease or increase depending on the size of your home, so always budget a little more than expected to ensure you don’t end up rushing to get it done.

Yes, you can technically use a pressure washer to remove paint from brick, but it comes with a significant risk of damaging the brick surface. A high-power pressure washer can be fast but may leave the brick looking unsightly. The recommended method is to first apply a chemical paint stripper, following the product's instructions, and then use a stiff metal bristle brush or a pressure washer on a low-pressure setting to remove the loosened paint. Due to the risk of damage, it is often best to hire a professional who can use low-stress methods.

The ideal frequency for pressure washing depends on the surface being cleaned and your local environmental conditions. For a home's exterior with siding that is safe to wash (such as vinyl, cement, or aluminum), a full wash once or twice a year is a good guideline to remove accumulated dirt, grime, mold, and mildew. You may need to wash more frequently if you live in an area with heavy rain or snow, near a dirt road, or if you notice excessive buildup. Other surfaces have different schedules; for example, a frequently used driveway may need cleaning more often, while outdoor patio furniture might only need to be washed every few years. Use your discretion based on how dirty the area gets.

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.
