Remedial sealant in Gatton
Some sealant jobs aren’t a simple reseal, because someone has already had a go. New sealant over old, smeared beads, unsuitable products and hidden mould all have to come out before the joint can be done properly. We work on mouldy bath & shower sealant, expansion joints and botched or over-sealed joints, and the jobs we see most are sealant that came away because the surface wasn’t prepared and decorators’ caulk around a bath or shower.
Homes around Gatton are mostly houses and cottages rather than flats. The work is the same as anywhere: everything old comes out before the new sealant or grout goes in.
We stand behind the work with a one-year guarantee, so you’re covered after we have gone.

What sealant work can’t fix
We’d rather tell you now than do work that will not last, so these are the limits:
- Plumbing leaks behind walls or under trays
- A tray or bath that is cracked
- Failed tanking or loose tiles behind the sealant
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Failed movement joints
- Shrunken worktop sealant
- Expansion joints
- Mouldy bath & shower sealant
DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.

You don’t need to know the technical terms. Just tell us:
- The problem you’ve noticed
- Whether it has been sealed before

Why it’s worth doing now in Gatton
Ripping out a bathroom is not generally needed. If the bath, tray and tiles are sound, remedial resealing usually puts it right. If they’re not, we’ll tell you. Older cottages and farmhouses around Gatton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and give you a clear quote before any work starts.

Surface by surface
Windows & doors
Frames resealed over the top end up with hard, layered mastic. We remove it all and clean back to sound surfaces before backing and resealing.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We take care not to make it worse, and tell you about any damage we find.
Bathrooms and kitchens in Gatton
Hard water is the norm across most of the South East, so limescale builds up on sealant, grout and fittings.
Homes close to St Andrew's Church include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant. Managing a site like Lime Tree Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. Letting a property close to Merstham station? Then botched sealant from a previous quick fix is easier to strip out between tenants.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a typical bath or shower, longer where several layers have been applied, and the area is left clean. In a small place like Gatton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- Surrounding tiles, trays and frames are protected first.
- The botched or failed sealant is cut away completely.
- The joint is degreased and checked for movement and leaks.
- New sealant goes in once the joint is dry, and is tooled smooth.
- You get the cure time and our view on why the joint failed.

How long before the joint can be used?

Aftercare tips
Aftercare is simple, and it makes a real difference:
- Don’t wait for a small gap to become a leak
- Run the fan after every shower
- Never fill a movement joint with mortar or grout
- Do not add new sealant on top of old
Ventilation keeps mould away from the new bead: run the fan during and after showers, or open a window.
A split movement joint lets rain into walls and floors, and the longer it’s left, the more the joint edges break down. A joint with sound edges is far easier to reseal.
