Bath resealing, shower resealing and regrouting

Black mould in the silicone, grout that crumbles when you touch it and a gap opening up between the bath and the wall are signs a bathroom needs attention, but not necessarily a new one. CRF Services Ltd reseals baths and showers and regrouts sound tiles across Rochester and Medway, so the room stays watertight for longer. If you are not sure whether your tiles can be saved, the [regrout or retile guide](/guides/regrout-or-retile-bathroom) helps you decide before you book.

Bath resealing done properly

A bath moves slightly when it is filled and when someone gets in, which is why the joint along the wall is sealed with flexible silicone rather than grout. Resealing starts by cutting out every bit of the old silicone, not running a new bead over the top. The joint is cleaned of soap and mould, treated, and left to dry fully.

Before the new bead goes on, the bath is filled with water so it sits at its lowest point. That way the silicone cures in the stretched position and does not tear the first time the bath is used. The bead is run in one even line, tooled smooth and left to cure before the bath is emptied and used again.

Shower resealing

Showers get more water on their joints than baths, so their sealant fails sooner. The tray to wall joint, the vertical corners and the screen fixings are all cut out, cleaned and resealed. If the tray flexes underfoot or the old silicone keeps splitting in the same spot, the problem may be the tray rather than the sealant, and a shower tray replacement may be the lasting fix. Why mould keeps returning is explained in the mouldy shower sealant guide.

Regrouting tiles

Regrouting is for tiles that are still firmly stuck and flat but whose grout has cracked, stained or washed out. The old grout is raked out to an even depth without chipping the tile edges, the joints are vacuumed and cleaned, and fresh grout is pressed in, shaped and cleaned off the face of the tiles. Corners and the joint at the bath or tray are finished with silicone, not grout.

If tiles sound hollow when tapped, or move when the grout is removed, they are coming away from the wall and regrouting will not hold. In that case, part or all of the wall may need retiling, covered on the bathroom tiling page.

  • Old silicone cut out completely
  • Old grout raked out to an even depth
  • Joints cleaned, treated and dried
  • New grout pressed in and finished
  • New silicone run at the bath, tray and corners

Patio and floor regrouting

Regrouting is not only for bathrooms. Kitchen and hallway floor tiles with worn grout can be raked out and regrouted in the same way, and the pointing between patio slabs can be raked out and renewed when weeds push through or the joints have washed away. Patio joints use an outdoor jointing mortar or compound rather than tile grout, and the work is planned for a dry spell.

What regrouting and resealing cost depends on

The cost of a regrout depends on the area of tiling, the width and depth of the joints, how hard the old grout is to remove and whether any loose tiles need refixing first. Resealing a single bath is a short job; resealing and regrouting a full shower enclosure takes longer. Several small bathroom jobs are best grouped into one visit, and each is quoted in writing after photos.

Common questions

Bath resealing, shower resealing and regrouting questions answered

It depends on the tiled area, the joint size and how stubborn the old grout is. Each job is quoted from photos or a visit.

Silicone needs time to cure before the shower is used, usually a day. The exact time depends on the product and the room temperature.

So the bath sits at its lowest point while the silicone cures, which stops the seal tearing when the bath is used.

No. Loose or hollow tiles need refixing or retiling first, otherwise the new grout will crack again.
