Grand Slam Maintenance was founded by Brendan Loeppky, a dedicated college athlete whose journey began with a 10-day contract for the Edmonton Riverhawks during their inaugural season. After seven consecutive 10-day contracts, Brendan earned a permanent spot and still proudly plays for the Riverhawks today. That same grit, hustle, and team-first attitude are the foundation of everything we do at Grand Slam.

​

We’re not just a service company — we’re a purpose-driven team committed to excellence. Brendan started Grand Slam with a vision: to deliver professional exterior cleaning services while creating reliable, flexible jobs for student-athletes chasing their dreams. We understand the discipline it takes to balance school, sport, and work — and we believe that same dedication is what makes our team the best in the game.

​

When you hire Grand Slam, you’re getting more than just clean windows or a spotless driveway. You’re getting dependable, hardworking people who take pride in doing the job right — the first time. We back every service with a satisfaction guarantee. That means we don’t pack up until you’re happy, and if you spot something we missed after the job, we’ll come back and make it right.

​

Our attention to detail, professionalism, and commitment to customer satisfaction is what makes us different — and why our clients keep calling us back. From pressure washing to gutter cleaning to Christmas lighting, we show up ready to deliver a Grand Slam experience, every time.
