About Us

Welcome to Reliance Window Cleaning Services, a local, family-run business built on a foundation of hard work and dedication.

The business is owned and operated by Jack and Maddy, a married team committed to providing Sleaford and the surrounding areas with a premier cleaning service. Jack’s journey began at just 16 years old, starting the company immediately after leaving school with a vision for high-quality service. Following their wedding in 2021, Maddy joined the business, making Reliance a truly family-oriented operation.
