"Very professional. They had an issue with the pressure washer. Came back the next morning (worked with me on time) to finish. While they were here on day 1, they noted additional things for me: 1) roof had mold/moss on it 2) gutter was not pitched correctly They gave me a "package deal" for the power washing and roof cleaning. it looks great. Gutters look like new. Stucco (that was stained and black under the deck) looks like new. I'm very happy and would recommend!"

Pressure Washing FAQs, answered by experts

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. 

Yes, you can safely pressure wash vinyl siding. As a durable material, vinyl can typically withstand pressure up to 3,000 PSI, holding up better than other siding types like aluminum or stucco. However, it's crucial to operate the pressure washer correctly to avoid damage. Before you begin, repair any existing cracks or damage to the siding. For a safe setup, use a 15- or 25-degree nozzle and maintain a distance of at least three feet from the siding to prevent splashback and damage.

If you don’t use the right PSI setting for your fence’s material, then yes, pressure washing can ruin your fence. Specifically, if you use a PSI that's too powerful, you may permanently damage a fence. Pressure washers can also remove paint from fences, though this can be a great thing if you’re looking to restore an old wood fence.

You should wait until your pavers have completely dried and cured before pressure washing them. Wait at least three to five days, though some sealants may need up to an entire week. Rushing that timeline can mess with the finish, weaken the seal, or leave streaks that are tough to fix. Once the sealant has fully set, stick to a gentle approach. Keep the pressure under 1,500 PSI and hold the nozzle at least two feet from the surface. Anything stronger or closer can blast the joint sand loose or wear down the sealant you just applied.

You don't technically need to seal your driveway after pressure washing, but doing so will help keep your driveway clean for longer. The best driveway sealer depends on the type of driveway you have. To seal asphalt, consider an asphalt emulsion sealer, fast-drying sealer, or latex acrylic sealer. Concrete driveways commonly use acrylic sealers or penetrating sealers.
