"They were very courteous, setting up an estimate, working with me via text, and worked around my schedule to get my gutters cleaned. When cleaning the gutters, he was quick and washed off my walkway afterwards. I really appreciated their work and I will get their service in the future!"

"Luke, Bryan and Bhakti did an outstanding job for us. We wanted to open up our floor plan for the living and dining areas so they did the demo of a wall, then re-plastered the ceiling which involved matching a complicated ceiling plaster design. They also removed some decorative mirrors in the living area again, repaired the drywall and matched the plaster pattern. They also applied a skim coat to the kitchen walls then painted everything they had repaired. Luke was very knowledgeable as was his team. They were very service minded, courteous and friendly. Luke took the time to discuss the project daily with me and reviewed their progress/plans. There were no hidden costs and Luke also made sure he and his team met their deadline. We have found our team for all of our Handyman services, for sure."

Pressure Washing FAQs, answered by experts

You should never use bleach in a pressure washer. While bleach is effective at killing mold and mildew, it is a potent chemical that can corrode the machine's seals and nozzles, destroying it from the inside out. Additionally, pressure washing with bleach sprays the chemical into the air, which is dangerous if inhaled and can kill nearby plants, flowers, or harm animals that ingest it. If you need to remove mold or mildew, it is best to hire a professional who will use a safe and effective cleaning agent.

Powerwashing services for businesses typically range from $200 to $1,500, depending on surface size, level of grime, and cleaning methods. Heavily stained or high-rise buildings may require additional labor and equipment.

The ideal PSI (pounds per square inch) for a pressure washer depends on the surface you are cleaning. For general home use, a pressure washer with a range of 2,000 to 3,000 PSI is recommended and powerful enough for most residential projects.

The specific PSI you should use varies by task:

  • High-Pressure Tasks (2,500-3,000 PSI): Tough materials like concrete, stone, masonry, and brick can handle higher pressures. This is suitable for removing stubborn stains from driveways or cleaning graffiti.

  • Low-Pressure Tasks (around 600-1,300 PSI): Softer surfaces require a gentler touch to avoid damage. Use a low PSI setting for cleaning wood decks (especially softwoods like pine and cedar), vinyl siding, outdoor furniture, and stucco.

For best results, choose the right nozzle for your surface, such as a 15-degree nozzle for siding or a surface cleaner attachment for driveways. Using an extendable wand can also make the work easier and more ergonomic.

Costs depend on fabric type, drape size, cleaning method, and whether additional services like pressing or deodorizing are included.

You should always hook up your pressure washer to the water supply before turning it on and ensure there’s a good water flow. If you try to turn the machine on without water in the system, it overworks and overheats the unlubricated pump. This can quickly lead to irreversible damage.
