DIY Tile Grout Gone Wrong: Why You Should Call a Professional

A small gap in your bathroom tile grout may seem harmless — until you find yourself with a leaking bathroom floor or damp patches on the ceiling below. Many homeowners in Singapore try quick DIY tile grout repairs to save time and money, but unfortunately, these fixes often lead to more damage (and higher repair costs) later.

Why DIY Grout Repairs Often Fail

Tile grouting looks simple, but it’s a skill that requires precision, proper materials, and waterproofing knowledge. Here’s why DIY grout jobs often go wrong:

‍

- Wrong Type of Grout Used
Not all grout is waterproof. Using regular or low-grade grout in wet areas can allow moisture to seep beneath tiles.‍

‍

- Poor Surface Preparation
Most people who DIY often skip cleaning out old or damaged grout properly before applying new material. This prevents the new grout from bonding securely.

‍

- No Waterproofing Layer Beneath Tiles
In bathrooms, a proper waterproofing membrane is crucial. Without it, water seeps into the concrete, causing leaks, mould, and structural damage.

‍

- Uneven Application
Uneven grout lines can trap water, weaken tiles, and allow moisture to spread under the surface.

Signs of a Lousy Grout Job

If you notice these warning signs, your grout is likely compromised:

• Hairline cracks or missing grout between tiles
• Persistent dampness or mould in corners
• Loose or hollow-sounding tiles
• Water leaking to the floor/room below

At this stage, tile grout repair is more than just cosmetic — it’s about preventing water seepage and protecting your home’s structure.
