Need a Home Services / Solar Panel Cleaning Contract in Washington? AroundWire Can Help

In Washington State, contracts for home services such as solar panel cleaning typically require clear definition of service scope, frequency, and safety protocols, especially given the potential for roof work and fall risks. While solar panel cleaning does not require a specialty contractor license, general business licensing with the Washington State Department of Revenue is mandatory, and local city business licenses may also apply. Contractors are expected to comply with Washington’s Consumer Protection Act, ensuring transparency in pricing, terms, and cancellation policies. Insurance obligations are significant; service providers should carry general liability insurance (commonly $1 million per occurrence) and, if employing workers, valid workers’ compensation coverage as required by the Washington State Department of Labor & Industries. Risk mitigation provisions often address property damage, personal injury, and indemnification. Payment terms usually specify completion-based milestones, with final payment upon satisfactory inspection; state law prohibits contractors from taking more than a modest deposit (generally no more than 10% or $1,000, whichever is less) before work begins. Contracts should also outline procedures for dispute resolution, with mediation or arbitration favored over litigation per industry best practices. Prevailing wage laws generally do not apply unless the client is a public entity. Environmental regulations may affect cleaning agents used, as Washington restricts certain chemicals to protect stormwater systems. Finally, contracts should reflect local norms for prompt communication and documentation, supporting consumer trust and regulatory compliance.
