Anyone can buy a pressure washer and print a flyer. Telling a real company apart from that takes about three questions. Here is what to ask, and what the answers mean.
Question one: what PSI do you run on each surface?
This is the fastest filter. If the answer is one number for your driveway and your roof, walk away. Different surfaces need genuinely different setups. A pro will tell you the driveway gets high pressure and the roof and stucco get low-pressure soft washing. Someone who treats every surface the same is going to damage the delicate ones.
Question two: what are you putting on the roof and walls?
A real soft wash uses a cleaning solution that kills the algae and mildew at the root. If someone says they will soft wash your roof with just water at low pressure, that is rinsing, not soft washing, and the streaks will be back within months. The chemistry is the whole point.
Question three: licensed, insured, and is the price flat?
Licensed and insured protects you if something goes wrong on your property. A flat, upfront price protects you from the number climbing once the crew arrives. A quote that cannot be given until someone has seen the property or clear photos is a good sign, not a bad one. It means they are pricing the real job.
The red flags
Watch for a whole-property price from someone who never asked what your surfaces are made of, a quote suspiciously lower than everyone else, and any hesitation on the insurance question. The honest version of this business is specific about surfaces, upfront about price, and happy to answer all three questions. That is the standard we hold ourselves to, and you can start a flat quote or just read how we work.
Common Questions
What should I ask before hiring?
Ask what PSI they run on each surface, what they put on the roof and walls, whether they are licensed and insured, and whether the quote is flat or could change. The answers tell you fast whether they know the work.
Is the cheapest quote usually a problem?
Often. The cheapest number in Miami is frequently someone planning to pressure wash surfaces that should be soft washed, which is how roofs and stucco get damaged. Price the method, not just the number.
Does licensed and insured actually matter?
Yes. If someone is on your roof or around your property without insurance and something goes wrong, that becomes your problem. It is a fair question to ask and a fair thing to expect.
