Corner grouting

Corner Grouting

Corner grouting is the finishing step that makes tiled rooms look complete and stay protected. The corners where walls meet, and where walls meet floors, are exposed to movement, moisture, and daily cleaning. When these joints are left open, filled poorly, or start to crack, water can seep behind tiles and cause staining, mould growth, and loose sections over time. Our service restores neat, clean lines and creates a durable barrier that helps your tiled surfaces last longer.

Why Corner Grouting Matters

Corners are stress points. Buildings settle, temperatures change, and bathrooms and kitchens expand and contract with humidity. These small movements often show up first in corner joints, where traditional grout can fracture and crumble. Once a crack forms, it can trap dirt and allow moisture to travel behind tiles, which is especially risky around showers, baths, splashbacks, and utility rooms.

We focus on both appearance and protection. A properly finished corner joint gives tiles a crisp, uniform look while reducing the risk of water damage. If your tiles are part of broader floor maintenance services, refreshing corner joints is a smart way to extend the life of the installation and avoid larger repairs.

Our Corner Grouting Process

1. Inspection and preparation

We begin by checking the condition of existing grout or sealant, looking for cracks, gaps, mould, and movement. We also examine nearby tile edges for chips or hollow spots. Preparation is key, so we remove loose material and clean the joint thoroughly to ensure strong adhesion and a tidy finish.

2. Careful removal of failed grout or sealant

Where old grout has deteriorated, we take it out with the right tools to avoid scratching tile surfaces. For corners that were previously sealed, we remove old silicone cleanly and strip residue so the new joint bonds properly. This step is essential for preventing early failure and keeping the corner line straight.

3. Regrouting and sealing for a clean, durable joint

After preparation, we install the correct corner joint finish for the location. In many wet areas, a flexible sealant is used to handle movement and keep water out. In other areas, a suitable grout solution may be appropriate depending on tile type and the joint design. We tool the joint for a smooth profile, clean excess material, and leave edges sharp and consistent.

4. Final clean up and curing guidance

We finish by wiping down tiles and ensuring the corners look even from end to end. You will receive clear advice on curing times and when the area can be used again, which is especially important for showers and floors. If the corner work is part of a wider refresh, we can coordinate it alongside floor repair services so everything is completed in the right order.

Where Corner Grouting Helps Most

Corner grouting is useful anywhere tiles meet at an angle or transition between surfaces. Common areas include bathrooms, kitchens, hallways, and commercial washrooms. It is also a practical solution after renovations, leaks, or tenant turnover, when hygiene and presentation need to be restored quickly.

• Showers and wet rooms to reduce water ingress at wall corners and floor junctions
• Bath surrounds to prevent staining and mildew build up in hard to clean edges
• Kitchen splashbacks for a neat finish that resists grease and moisture
• Utility rooms where frequent cleaning and damp conditions stress corner joints
• Commercial spaces where high traffic and strict hygiene make clean joints essential

Common Signs You Need Corner Grouting

If you notice any of the issues below, corner joints may be failing and should be addressed sooner rather than later. Early repairs are usually faster and less disruptive than fixing water related damage behind tiles.

1. Visible cracking or missing material in the corner line
2. Dark staining that returns soon after cleaning
3. Mould or musty odours around showers and baths
4. Loose or hollow sounding tiles near corners
5. Gaps where water can sit or run behind the surface

Corner joint work pairs well with broader updates to tiled areas. If you are planning a refresh of adjacent finishes, our team can align the work with your professional flooring services to keep transitions clean and consistent.
