"These folks did a great job, from my initial call to them to learn about their low pressure washing system for our house. They did an excellent job detailing the process and setting up the appointment. They came on time, and made a 30 minute call ahead as I requested, and did an excellent job. Am very happy and everything was as promised. Would hire them again for sure."

We use a special proprietary blend of cleaning agents that will not only kill all of the growth, it will greatly lengthen the time required between cleanings. This solution will not harm people, plants, or animals and is not harmful to the roof itself.

"Steve and his son Dylan did two jobs for us. One at our house where they stained the deck as well as power wash the exterior and patio. They also power washed the exterior of my father-in-law's house. They are courteous, punctual and do an excellent job. Their pricing is very competitive. I would recommend them gladly."

Pressure Washing FAQs, answered by experts

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.

It‘s risky to pressure wash indoors, and we wouldn’t recommend it, but following all safety guidelines can prevent the worst outcomes. Always make sure to use an electric-powered machine over one that’s gas-powered, remove obstacles that could cause tripping or falling, and keep appliances like hair dryers and toothbrushes unplugged and out of the way to prevent electrical hazards. 

Concrete does well with a number of cleaning agents, as it’s a durable material. Choose from acidic cleaners, alkaline cleaners, and pH-neutral cleaners, in addition to antibacterial solutions. Your best bet is to simply read the fine print with your preferred detergent and make sure it mentions concrete as a viable surface. 

Yes, it is highly recommended to wash a house's exterior before painting to ensure the best results. Cleaning the surface removes dirt, dust, grime, mold, mildew, and old paint, which allows the new paint to adhere properly and results in a smoother, long-lasting finish. Failing to clean can lead to poor adhesion, peeling, and an uneven appearance. Pressure washing is an efficient method for this, but be cautious not to use excessive pressure that could damage siding or wood. For materials like vinyl or stucco, soft washing might be a better option. After washing, allow sufficient drying time, such as three to four days, before painting to prevent trapping moisture, which can cause blistering or peeling.

No, pressure washing isn’t recommended for cartridge filters. The high pressure can damage the filter paper, and the gentler pressure from a regular garden hose will work to rinse the cartridge filter. If the cartridge is very dirty or has algae or mineral buildup, you can use a muriatic acid solution to soak the filter and remove the buildup.
