About our remedial sealant in Ashtead
Some sealant jobs aren’t a simple reseal, because someone has already had a go. Silicone laid over silicone, smears across tiles, the wrong product in a moving joint or mould trapped underneath all need stripping out. We work on mouldy bath & shower sealant, expansion joints and failed movement joints, and the jobs we see most are a second bead peeling off the first and wide, uneven beads that look worse than the old ones.
Most bathrooms in a town like Ashtead are in family homes, used every day, which is hard on sealant and grout. The usual signs are mould in the bead, gaps by the sink and grout that is cracked or stained.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What happens if it’s left?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. Dealing with the joint now is a small job by comparison. Gaps in sealant and mould in the bead never get better on their own, and in a busy home in Ashtead they get worse with every use. Now is the easy time to put it right.
Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Keeping the joints in good condition
Looking after new joints is easy, and it makes a real difference:
- Always have old sealant cut out, not covered
- Keep an eye on the ceiling below the bathroom
- Clean sealant with mild products only
- Keep the room well ventilated
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

The process
At the end, we look at the finished work together. The work normally takes a few hours, depending on how many layers have to come out, depending on the size of the job. A visit in Ashtead needs access to the work and a place to park close by. For outside work, let us know about side access, gates and any upper-floor joints.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.

Different surfaces, different methods
Over-sealed & botched joints
Every layer has to come out, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Leaking trays & enclosures
A shower that leaks after resealing often has a tray that moves or an enclosure sealed on the wrong side. Both are checked before we reseal.
Ashtead homes and their sealant
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you let a flat or house near Ashtead station, a joint that keeps failing is best fixed properly while the property is empty. Schools such as Parsons Mead School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes. In the older streets around St George's Church, walls and floors in older homes can move, and sealant and grout show it first.
