Pressure Washing Services

The County of San Mateo, Department of Public Works, is conducting a Request for Proposals (RFP) to procure pressure washing and window washing services on an as-needed basis for multiple County facilities. The scope of services includes power washing of horizontal and vertical surfaces such as sidewalks, exterior walls, parking lot curbs, flat roof surfaces, and covered walkways, as well as interior and exterior window washing on all building floors. A specific focus area is the Hall of Justice and County Office Building 1 Project in Redwood City, which involves pressure washing and window cleaning of an eight-story Hall of Justice building and a five-story County Office Building 1, including bird netting removal and replacement. All work must be performed between 7:00 a.m. and 5:00 p.m., Monday through Friday, excluding County holidays, with coordination required for any evening or weekend emergency work. Minimum qualifications require proposers to demonstrate at least four years of similar service experience within the last seven years, maintain an active C-61/D-36 Limited Specialty License, comply with environmental regulations for wastewater disposal, and be registered with the System for Award Management (SAM). Contractors must also comply with all OSHA safety regulations, provide appropriate equipment for elevated access work, implement storm drainage protection measures, and obtain necessary encroachment permits. Evaluation criteria are weighted as follows: service approach (40 points), experience and organizational capacity (25 points), and price proposal (35 points). Pricing proposals must be submitted on a per-square-foot basis for pressure washing services and per-pane basis for window washing, with all rates listed as prevailing wage. The deadline for questions and contract exceptions is May 13, 2026, at 2:00 p.m., with proposals due electronically via OpenGov on May 20, 2026, at 2:00 p.m., and an anticipated contract award date of June 23, 2026.

The County of San Mateo has adopted a Procurement Preference for Local Businesses Ordinance that may apply to this solicitation, potentially favoring local business entities in the evaluation process. No pre-proposal conference or site visit is scheduled, and no incumbent contractors or current vendors are identified in the available materials. The selected contractor will enter into an agreement for an aggregate fiscal obligation not to exceed $2,000,000 over a term of up to five years, with separate Task Orders to be issued as work is warranted throughout the agreement period. The County anticipates awarding the contract to one contractor. Prevailing wage requirements under California Labor Code Section 1770 et seq. apply to this procurement, and the contractor must obtain all required licenses and permits at its own expense prior to commencing work. The successful contractor will be required to maintain comprehensive general liability insurance of at least $1,000,000, motor vehicle liability insurance of $1,000,000, and professional liability insurance of $1,000,000, with the County named as an additional insured, ensuring adequate financial protection and professional capacity for the duration of the agreement.
