When you hire Grand Slam Maintenance, you’re supporting college athletes chasing their dream of playing at the next level.

Grand Slam Maintenance was founded by Brendan Loeppky, whose journey started with a 10-day contract playing for the Edmonton Riverhawks during their inaugural season. After seven back-to-back 10-day contracts, the team couldn’t let him go — and today, Brendan is still proudly playing for the Riverhawks.
That same drive and passion fuel Grand Slam Maintenance. Brendan brings the grit and determination he’s known for on the field into every job the company takes on.
His vision for Grand Slam goes beyond just spotless windows and fresh siding — it’s about creating a business that supports university athletes with flexible, reliable work while they pursue their dreams. When you hire Grand Slam, you’re not only getting quality service with a satisfaction guarantee — you’re also helping student-athletes keep playing the game they love.

What we do best
Residential
Commercial
Interior/ Exterior
At Grand Slam Maintenance, we clean not only the glass but also take care to wipe down the window seals and clear out dirt and debris from the tracks. Our thorough process ensures your windows look great and function smoothly, inside and out.
Soft Washing/ Power washing
We use high-pressure water to blast away built-up grime, algae, and stains from hard surfaces like concrete, siding, and decks. For more delicate areas, our soft washing method uses low pressure and eco-friendly solutions to safely clean without causing damage.
Gutter Cleaning
We remove all debris by hand or with specialized tools to ensure water can flow freely. We also flush the downspouts and check for blockages to help prevent leaks, water damage, and foundation issues.
Holiday Lighting
We handle everything from design and installation to takedown and storage. Our team ensures your home shines bright and safe all season long—without you ever needing to climb a ladder.
