Checklist: Hiring a Commercial Power Washing Contractor on Long Island
What property and facility managers should ask before hiring a commercial power washing contractor: insurance, methods, scheduling, wastewater, and references.
Insurance and compliance
Ask for a Certificate of Insurance naming your property or management company before work starts. If your company uses a contractor management platform like ISNetworld, confirm the contractor is a member in good standing.
Methods and surface protection
Ask how they will clean each surface. A good contractor soft washes EIFS, stucco, and painted surfaces and uses hot water pressure on concrete and masonry. Ask what cleaning solutions they use and how they protect landscaping, windows, and signage.
Scheduling and site safety
Confirm they can work around business hours, tenants, and deliveries. Ask how they will cone off work areas and keep walkways safe.
Wastewater and cleanup
Ask how wash water is handled around storm drains, especially for degreasing jobs like dumpster pads and parking lots.
Written scope and references
Get a written quote listing surfaces, method, schedule, and price. Ask for references from similar commercial properties and read their reviews.
