"They cleaned our gutters and power washed the house when the gutters did not appear as bad as we feared. We hired again to roof wash and power wash the house this year. They did a great job and washed some of the windows that we requested all within our budget."

"Todd did an amazing job power washing my property. I was honestly surprised by how much of a difference it made.. everything looked so much cleaner and brighter when he was done. He was professional, showed up when he said he would, and clearly takes pride in his work. The attention to detail really stood out, and the whole process was easy from start to finish. If you?re looking for someone reliable who does great work and charges a fair price, I definitely recommend Todd and his company. I?ll absolutely be using them again in the future."

"I have hired the INEX crew to replace the floor and top of the railing on my deck. They did a great job. Gave me a very reasonable price. Showed up on time and finished job in one day. Ron takes great pride in his work and his costumers. They are coming back in few weeks to power wash and stain my deck. I am very happy with the results and definitely hire them again. I highly recommend this company. Great work guys !!! Thank you !!"

Pressure Washing FAQs, answered by experts

It is generally not recommended to use dish soap in a pressure washer. Dishwashing liquid is formulated for cooler water, and the warmer water used in a pressure washer can create excessive suds, potentially damaging the machine's tubing and other components. Always check the manufacturer’s instructions for recommended detergents. If you find yourself in a pinch, you can try a highly diluted solution, such as one tablespoon of dish soap per 1.5 quarts of water, to avoid clogging the machine.

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.

The life expectancy of a pressure washer depends on the model, its overall quality, and how well it is maintained. Most pressure washers have a life expectancy rating, typically measured in hours of use. Many models are rated for up to 500 hours, which can translate to a lifespan of around 10 years for a homeowner who uses the machine for about 50 hours per year. If you plan on using your pressure washer regularly, you may want to look for a higher-quality model rated for 2,000 hours or more.

It’s not necessary, but you can absolutely use soap or detergent when pressure washing your house. Washing with a mixture of soap and water will ensure your siding is spotless when you’re finished. However, in many cases it is not necessary to use soap and you can still achieve a powerful result without any product. 

Professionals use high-pressure steam cleaners, brushes, and specialized cleaning solutions for effective results.
