What is the cost to professionally clean and reseal tile grout throughout an Ottawa home?

Professional grout cleaning and sealing typically costs $300 to $1,500 in Ottawa depending on the total square footage of tiled surfaces and the condition of the grout. For an average home with tile in a bathroom or two, a kitchen backsplash, and perhaps an entryway, you're usually looking at $400 to $800. Larger homes with multiple bathrooms and extensive tile throughout may reach $1,200 to $1,500. Labour typically runs $25 to $50 per hour, with the contractor charging either hourly or providing a flat rate for the entire job based on footage and grout condition.

The cost depends heavily on how dirty the grout is and what type of sealer you choose. If grout is heavily soiled with mould, soap scum, and mineral deposits — which is common in Ottawa bathrooms after several years — the cleaning takes longer and may require specialized equipment like a grout cleaning machine or steam cleaning. Deep cleaning can add 30 to 50 percent to the labour cost. Light cleaning of relatively clean grout is obviously faster and cheaper than tackling black, stained grout in a shower.

The sealer choice affects price. Standard penetrating grout sealers (acrylic or silicate-based) cost $3 to $8 per square foot applied and offer reliable protection for one to two years in Ottawa's challenging climate. Premium penetrating sealers that last three to five years cost slightly more. Membrane sealers that sit on top of the grout rather than penetrating into it are thicker and more visible but can last longer — expect to pay a modest premium. In Ottawa's salt-laden winters, properly sealed grout in entryways and mudrooms extends grout life dramatically compared to unprotected grout.

Important considerations for Ottawa: Grout in high-traffic areas exposed to road salt, melting snow, and the freeze-thaw cycle deteriorates much faster than grout in interior bathrooms or kitchens. If your grout is in an entryway or mudroom, plan to reseal it annually as part of your winter maintenance routine — it's the most cost-effective way to prevent expensive grout replacement down the road. Epoxy grout, which never needs sealing, is worth considering if you're replacing grout in these punishing areas.

Get quotes from at least two tile contractors in Ottawa — a professional cleaner can often assess the grout condition over photos or a quick visit and provide a more accurate quote than a ballpark estimate. Make sure the quote specifies the square footage being covered, whether deep cleaning is included, and which sealer product will be applied. If your grout is heavily discoloured or cracked, the contractor may recommend full grout removal and replacement rather than just cleaning and sealing — that's a different project with higher costs but sometimes the better long-term option.
