Small jobs, properly finished
Regrouting and resealing
Failed grout and mouldy silicone are more than cosmetic. Once water gets behind tiles it can soften the backing, loosen the tiles and find its way into the ceiling below. Regrouting and resealing puts that right: the old material is removed, the joints are cleaned out, and new grout and sanitary silicone restore the waterproof surface.
How we work
What is regrouting?
Regrouting means raking out the old grout from between tiles and applying fresh grout. It is worth doing when the grout is cracked, crumbling, missing in places or permanently discoloured, but the tiles themselves are still sound and well fixed. If tiles are loose, hollow-sounding or the wall behind them has moved, regrouting alone will not hold them; that points towards retiling, and our guide to [regrout or retile](/guides/regrout-or-retile) explains how to tell the difference.
Resealing is the companion job: stripping out old silicone from around the bath, shower tray, screen and basin, and applying fresh sanitary-grade sealant. Silicone has a limited life. Once it lifts, shrinks or goes black with mould that cleaning will not shift, replacement is the right fix.
What the work covers
Old grout raked out to a proper depth
Joints cleaned and allowed to dry
New grout applied and finished neatly
Old silicone cut away completely
Surfaces cleaned and dried before resealing
Fresh sanitary silicone tooled to a clean line
Loose tiles reported honestly, not grouted over
Is regrouting expensive?
Compared with retiling, no. Regrouting keeps the existing tiles, so there is no tile cost and no making good of the wall behind. The cost depends on the area involved, the condition of the joints and how much old material has to come out. A shower enclosure is the most common job; a fully tiled bathroom is a bigger one. We quote after seeing the room or clear photographs, so the price reflects the actual work.
Doing it once, properly
The difference between a regrout that lasts and one that fails again is preparation. Grout smeared over old grout does not bond; silicone over damp or dirty surfaces peels within months. We remove material back to a clean joint, let everything dry, and only then apply the new grout and sealant. It is not a long job, but it cannot be rushed past the drying stages.
Good to know
When to regrout, and when water is the real problem
Regrout when the joints are failing but the tiled surface is otherwise sound. If water has been getting behind the tiles for a while, the cause matters as much as the symptom. Our guide to leaking shower causes and fixes walks through the common culprits, and mould on walls explains when mould is a ventilation issue rather than a grout issue.
A note on timing: Martin is currently booked well ahead, so smaller jobs like regrouting are scheduled around larger projects. It is still worth getting in touch, because a leaking shower rarely improves by waiting, and we will tell you straight away if the problem sounds bigger than a regrout.

Common questions
Regrouting and Resealing: your questions answered
Can you regrout tile that is already down?
Yes, that is exactly what regrouting is. The old grout is raked out and replaced while the tiles stay in place, provided the tiles are still sound and well fixed.
When should I regrout my shower?
When grout is cracked, missing, crumbling or stays dark after cleaning, or when silicone has lifted or gone mouldy. Acting early keeps water out of the wall behind.
What is regrouting?
Removing the old grout from between tiles and applying new grout, without replacing the tiles themselves. It restores the waterproof surface of a tiled area.
Is regrouting expensive?
It is much cheaper than retiling because the tiles stay. The price depends on the area and the condition of the joints; we quote after seeing the room or photographs.
