"Provider did an excellent job once we were finally able to get him to come over. He was not familiar with the deck stain I bought so in turn we did not get the two coats applied like we wanted. This is partially my fault due to me not informing him that the two coats need to be applied Wet on Wet (applied within 20 minutes of each other). Other than that he showed up when he said he would and performed the work, and a little extra, in a timely and professional manner.

Pressure Washing FAQs, answered by experts

No, you should not pressure wash or power wash roof shingles, including asphalt shingles. The high water pressure from these machines is too strong and can damage the shingles by forcing water underneath, loosening their adhesive, and causing them to fall off. A safer and better alternative is soft washing with a pump sprayer. To ensure the job is done safely without causing damage, it is best to hire a local roof cleaner.

Use of harnesses and ladders ensures safe roof access.

It usually takes about two to four hours to pressure wash a 2,000-square-foot home. The exact time depends on how much dirt there is, the type of siding, and whether you’re doing it yourself or hiring a professional pressure washing service. A DIY job can take an average of six to eight hours, but you should plan for it to take an entire day. A pro can get the job done quicker.

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.

On average, pressure washing a house can take anywhere from 30 minutes to three hours. The time frame to pressure wash or power wash your home, fence, or other property depends on the size of the project and the complexity and accessibility of the areas that need cleaning. Part of the time required to complete the job includes setup and removal of equipment needed. A two-story house with a steep roof may require working from scaffolding or a ladder, likely adding to the time required to finish the project.
