How often should I recaulk my bathroom?

Bathroom caulk should typically be replaced every 1-3 years, depending on the quality of the original installation, the type of caulk used, and your bathroom's humidity levels. However, you should inspect it regularly and replace it as soon as you notice cracking, peeling, or mold growth.

Signs it's time to recaulk include visible cracks or gaps, discoloration that won't clean off, peeling or pulling away from surfaces, and any black mold spots that keep returning after cleaning. In Ottawa's climate, bathrooms with poor ventilation may need more frequent recaulking due to higher moisture levels, especially during our humid summers and when heating systems create temperature fluctuations in winter.

Quality matters significantly when it comes to caulk longevity. Premium 100% silicone caulk with mold and mildew resistance will last longer than basic acrylic caulk, though it's more challenging to apply smoothly. Many Ottawa homeowners find that investing in quality caulk and proper application extends the replacement interval to 2-3 years rather than annual touch-ups.

Proper preparation is crucial for long-lasting results. This means completely removing old caulk (not just applying over it), thoroughly cleaning and drying the surfaces, and applying the new caulk in optimal conditions - ideally when humidity is lower and temperatures are moderate. The shower or tub should be dry and shouldn't be used for 24 hours after application.

For best results and to avoid water damage from improper sealing, consider having recaulking done as part of regular bathroom maintenance by experienced contractors who can ensure proper waterproofing around tubs, showers, and sink areas.
