Securing post-construction cleaning jobs involves a mix of networking, marketing, and showcasing your expertise. Begin by identifying potential clients in your area, whether they’re commercial establishments, residential complexes, or individual homes. Tailor a proposal that highlights your services, rates, and any unique selling points. Attending local business events or joining Chambers of Commerce can provide networking opportunities. Cold calls, referrals, and advertising — both online and offline — can also be effective in landing contracts. Lastly, always deliver exceptional service — satisfied clients often lead to repeat business and referrals.
