Sinzere Janitorial Services was founded by Bertram Johnson with a simple but powerful mission: to prove that cleaning companies don’t have to overlook the small details that matter most. Starting with just basic equipment and an unwavering commitment to quality, we built our company on the principle of treating every space with the same care and attention you’d give to your own home. We believe that cleanliness is more than just removing dirt—it’s about creating professional, welcoming environments where businesses can thrive.

Today, we operate as a full-service janitorial team while maintaining the ‘mom-and-pop’ values that define us. We build genuine personal relationships with our clients, pay meticulous attention to every detail, and focus on keeping local businesses consistently clean, safe, and professional. Whether it’s routine office maintenance or flexible after-hours cleaning, we’re committed to exceeding expectations and proving that personalized service and quality craftsmanship still matter in the cleaning industry.
