Full services directory How it worksFor prosAbout Get matched Call (866) 582-8523AI tools are useful for working out which surfaces you have, which need soft washing rather than pressure, and what to ask a contractor. They cannot see the condition of your mortar joints, your shingles or your seals, and they cannot tell you what your specific product manufacturer permits. Use them to prepare, then verify method against the trade guidance and your own product documentation.
The genuinely useful thing here is method matching: listing your surfaces — roof type, siding type, deck material, driveway material — and working out which ones must be soft washed and which can take pressure. That list is exactly what you should hand to every bidder.
The second useful thing is question generation. Going into a quote knowing to ask about PSI per surface, dwell time, plant protection and insurance changes who you end up hiring.
What a tool cannot do: judge whether your mortar joints are sound, whether your seals are intact, whether your shingles are already shedding granules, or what your particular siding manufacturer permits. NPS guidance is clear that confirming the building is watertight is a pre-condition for water cleaning, and that is a physical inspection.
Verify any method advice against the primary sources — ARMA for roofs, the siding association for siding, NPS for masonry — and against your own product's care instructions. On roofs specifically, the answer is settled: ARMA says never pressure wash asphalt shingles.
That is worth something only while you are still choosing. Tell us what is going on and we will match you with a few pressure washing pros whose licence and insurance we have already checked — free, no obligation.
