PeakFlow Exteriors is a founder-operated, fully-insured exterior cleaning company built around one idea: do it the way the manufacturers actually recommend — pure de-ionized water, soft bristles, no harsh chemicals, no high-pressure blasting.
Most exterior cleaners in Washington still hit panels and windows with pressurized tap water and soap. That strips coatings and leaves mineral spots when it dries. We built PeakFlow on the opposite approach — water-fed poles where they work best, roof access with proper fall protection when the job calls for it, 100% de-ionized water, and a methodical pace that protects your investment.
