Great communication, prompt, professional in every way...even equipment, not your average guy bringing a portable pressure washer; truck mounted equipment. I would HIGHLY recommend!

"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

Pressure washing is a great way to take care of built-up messes much more easily and quickly than manual scrubbing. Pressure washing can save you energy, time, and even money by getting rid of contaminants that can lead to damage to your home. It can also increase curb appeal if you’re getting ready to make a home sale.

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.

Whether you need to winterize your pressure washer depends on where it will be stored. If it's kept in a location where temperatures could drop to freezing, any liquid left in the water pump can freeze, expand, and cause severe damage to the machine. To prevent this, you can add antifreeze to the pump. While emptying the machine with compressed air is an alternative, it can be a tedious process and may not remove all the liquid. If you can store the pressure washer in a relatively warm place with no risk of freezing, you won't need to add antifreeze. However, regardless of storage conditions, it is good practice to empty the gas chamber and refresh the oil before storing it for the winter.

Jet washers can last for up to 10 years, but a more exact timeline for your jet washer depends on the frequency of use and maintenance. Some machines are given a rating of their approximate total hours of usage, which can help determine how long yours will stick around based on how many hours you use it each year. Aside from learning how to properly use the jet washer, you’ll want to keep it stored safely and securely so that it won’t rust or get damaged between uses.

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.
