Musty Smell in the Bathroom

A persistent musty smell in the bathroom is often a sign of hidden moisture. This can occur when water escapes behind tiles or into surrounding materials and does not dry properly. In many cases, this type of moisture build-up is linked to a leaking shower and should be assessed early to help prevent further damage.

Wet Flooring or Damage Outside the Shower

If areas outside the shower are becoming damp or damaged, this may indicate that water is escaping beyond the shower recess. Signs can include wet flooring, rotted timber at the doorway, or peeling paint on nearby walls. This type of damage usually develops over time and should be addressed promptly to prevent it spreading into surrounding areas.

Cracked or Deteriorated Grout & Silicone

Cracked, deteriorated, or missing grout and silicone are one of the most common causes of shower leaks. These materials act as a barrier to water penetration around joints and tiled surfaces. When they begin to fail, moisture can pass beneath the tiles and contribute to ongoing water damage if not repaired.

Did You Know ?

Many leaking showers can be sealed without removing tiles

Many showers can be professionally sealed without removing tiles when the structure remains sound, helping avoid the cost and disruption of a full bathroom rebuild.

Proper shower sealing helps protect surrounding areas from ongoing moisture damage caused by deteriorated grout and failed silicone joints.

While DIY sealing products are widely available, long-lasting waterproofing results often depend on correct preparation, quality materials and professional application.

Shower Preparation

Existing floor & perimeter grout is removed to the required depth using specialised grout removal tools, including the shower hob if present.
Existing wall grout is removed in preparation for new mould-resistant grout. Some cement-based grout types can be difficult to remove without risking tile damage.
Existing silicone seal is removed from all internal shower junctions, including vertical joints.
Any visible mould within the shower area is treated and removed before sealing begins.

Epoxy Grout Application

High grade epoxy grout is applied to internal shower junctions, perimeter areas and around the floor waste to provide durable waterproof protection.

Epoxy grout offers strong water and chemical resistance while helping reduce cracking, peeling and ongoing maintenance.

Once the resealing process is complete, the shower area is cleaned, inspected and prepared for use following the recommended curing period.

What Causes a Leaking Shower?

Showers can leak for several reasons, which is why identifying the source of the problem is important before recommending a sealing solution.

Common causes of a shower leak include building movement, deteriorated grout, failed silicone joints, cracked seals and waterproofing issues beneath the tiled surface. In some bathrooms, more than one issue may be contributing to the leak.

Before beginning any shower sealing work, a professional assessment should be carried out to check the condition of the shower and identify the areas causing the problem.

At SealTech Solutions, we take the time to properly assess each shower before recommending the most suitable sealing and waterproofing solution.
