- Sealant that came away because the surface wasn’t prepared
Remedial sealant in St George's Hill, done properly
Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. Typical jobs include floor or wall movement joints that have failed and a second bead peeling off the first, across failed movement joints, shrunken worktop sealant and botched or over-sealed joints.
Even in a smaller place like St George's Hill, bathrooms and kitchens see heavy daily use. Whether it’s a cottage bathroom or a newer en suite, the approach is the same: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

Bathrooms and kitchens in St George's Hill
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. There are hotels and other places to stay in and around St George's Hill. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
If you live in an older home near United Reform Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them. If you let a flat or house near Weybridge station, botched sealant from a previous quick fix is easier to strip out between tenants. Schools such as Manby Lodge Infant School are buildings too, and we reseal washrooms and kitchens in schools and businesses as well as homes.

Can I do it myself?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Work for landlords, hotels and businesses
Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for a typical bath or shower, longer where several layers have been applied for a typical job. For a job in St George's Hill, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- Finally we finish the joint and talk you through what we found.
How to prepare
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Tell us if parking is tricky

Common questions in St George's Hill
Do you work for landlords with property near Weybridge station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you work for hotels and guest houses in St George's Hill?
Yes, hotels and guest houses are among the places we work. A room-by-room programme keeps most rooms in use while the work goes on.
Do the sealants smell?
Possibly a little. Any smell clears as the sealant cures, and ventilation helps.
Can you remove old sealant without damaging the bath?
Yes. We cut and lift the old sealant with tools suited to the surface, and the residue is cleaned away. We point out any damage that’s already there.
Can failed expansion joints be resealed?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
How long before the joint can be used?
Most sealants are touch-dry well before they’re fully cured. We will tell you how long to leave the joint.
Can you remove sealant that is been put over old sealant?
Yes. It’s slower than a standard reseal, because every layer has to come out cleanly, but it’s the only way the new joint will last.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
How to look after the new joints
Aftercare is simple, and it makes a real difference:
- Find out why the sealant failed first
- Always have old sealant cut out, not covered
- Use a soft cloth, not a scourer, on silicone
- Look for stains below bathrooms now and then
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, because the new sealant cannot hold back a problem underneath.
Don’t keep resealing the same joint. Get the cause found first, or the next bead will go the same way.
What happens if it’s left?
It’s easy to scratch acrylic, enamel or an uPVC frame cutting out old sealant, and any film left behind stops new sealant sticking. Careful removal is most of a remedial job. Homes in smaller places like St George's Hill can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.
