When should I recaulk my shower?

Recaulk your shower when you notice cracking, peeling, discoloration, or gaps in the existing caulk - typically every 1-2 years for most Ottawa homes, though high-use showers may need attention sooner.

Signs it's time to recaulk include visible cracks or gaps where water can penetrate, black or pink mold growth on the caulk lines, caulk that feels soft or pulls away from surfaces, or persistent musty odors that suggest water is getting behind tiles. Don't wait until you see water damage - prevention is much cheaper than repairs.

In Ottawa's climate, temperature fluctuations cause expansion and contraction that can accelerate caulk failure. Winter heating and summer humidity create conditions where caulk deteriorates faster, especially around tub edges and shower corners where movement is greatest. If your bathroom lacks proper ventilation, you may need to recaulk more frequently.

Choose 100% silicone caulk for wet areas rather than latex or acrylic versions. Silicone provides superior water resistance and flexibility. For tile showers, consider color-matched caulk that complements your grout. Proper surface preparation is crucial - remove all old caulk completely, clean with rubbing alcohol, and ensure surfaces are completely dry before applying new caulk.

Professional installation ensures proper waterproofing techniques and longer-lasting results. Poor caulking is one of the leading causes of water damage in Ottawa bathrooms, often leading to expensive repairs behind walls.
