Tile & Grout Cleaning and Colour Sealing in Toronto & GTA

Sentinel Maintenance Inc (SMI) offers professional tile and grout cleaning and colour sealing services that restore vibrancy to tiled surfaces while extending their lifespan. Over time, tiles lose their shine and grout lines accumulate dirt, stains, and mildew—especially in high-moisture environments. Our service combines high-pressure steam cleaning and stain removal with durable colour sealing to rejuvenate and protect your floors, walls, and backsplashes. The result is a cleaner, more uniform look that resists future grime buildup. We serve residential and commercial clients across Toronto and the GTA, treating ceramic, porcelain, stone, and other tile types. Whether refreshing a bathroom, commercial kitchen, or office lobby, SMI ensures your tile surfaces are deep-cleaned, sealed, and protected with industry-leading techniques.
