For complex or hard-to-find leaks, we recommend engaging a professional leak detection company that uses specialised equipment such as thermal imaging, dye testing, or pressure testing.

As a homeowner, you can perform two simple tests yourself to help determine whether the leak is coming from the waste drain pipe or from the tiled surface (grout and waterproofing membrane).

Important Note:
These basic tests help identify leaks from the drain pipe or the tiled surface. They do not detect leaks from main water supply pipes, wall grout, shower niches, or screens. For those issues, professional leak detection is usually required.

1. Waste Drain Pipe Test

Remove the waste grate from the shower or balcony drain (usually by twisting it anti-clockwise with a screwdriver).

If you have a hose:
Direct the hose into the drain hole and run water for several minutes.

If you don’t have a hose:
Fill 2-litre bottles with water and carefully pour them directly into the drain hole (avoid flooding the surrounding tiles). Repeat several times to simulate normal use. Check the ceiling and walls in the room below for any signs of dripping or damp patches.

If water appears below, the waste drain pipe is likely cracked or leaking — contact a plumber immediately.

If no water appears, proceed to the flood test.

2. Flood Test (Surface Test)

Block the drain grate completely using a large mug, plug, or similar item.

Pour water generously over the tiled surface (using a bucket or tap) and let it sit for 30–60 minutes.

Check the ceiling and walls directly below for any dripping, damp patches, or staining.

If water appears below during this test, the leak is most likely coming from cracked grout, failed sealants, or the waterproofing membrane beneath the tiles.

Next Steps

Once you’ve confirmed there is a leak, feel free to send us any photos or inspection reports. We can then assess the best way to permanently repair your balcony or shower leak with no tile removal where possible.

Yes, we can do a mixed grout approach — using epoxy grout on the shower base and standard cement-based grout on the walls.

This is a popular option for customers looking to keep costs down while still getting the best protection where it matters most. The shower base receives the heaviest direct water exposure and standing water, so epoxy grout on the floor is highly recommended as it provides superior waterproofing and durability. The walls generally receive less intense water exposure, so normal grout is often sufficient in those areas.

Important Note:
If a leak detection test has shown that water is penetrating through the wall grout (causing leaks behind the tiles), we would strongly recommend using epoxy grout on the walls as well for proper long-term waterproofing. However, if there is no active leak from the wall grout and you simply want to refresh the appearance for maintenance, then standard grout on the walls is perfectly fine.

We strongly advise against attempting DIY balcony shower repairs. While minor cosmetic fixes might seem simple, properly repairing a leaking balcony or shower requires specialised skills and tools.

Our technicians use professional equipment to carefully remove grout without damaging the existing tiles — a task that takes many years of experience and skill to do correctly.

DIY attempts often result in temporary fixes that can trap moisture behind the tiles, accelerate membrane failure, or cause even bigger and more expensive damage later.

Professional balcony shower repairs using the correct materials and proper surface preparation usually save you money in the long run by providing a permanent solution and preventing structural issues.

Important Note:
Epoxy grouts are technically demanding to install. They set quickly and require skilled, precise application and fast cleanup. Incorrect installation can leave haze or sticky residue on tiles. For the best results and a clean, professional finish, epoxy grout should always be installed by experienced professionals.

No, we’re not limited to just showers and balconies. We regularly re-grout and reseal many other wet and dry areas, including:

• Bathrooms (walls and floors)
• Toilets
• Kitchens
• Laundries

Whether it’s for maintenance, upgrading to epoxy grout, or fixing staining and mould issues, we can help refresh and waterproof these areas using the same high-quality materials and professional finish.
