Remedial sealant in Sandhurst
Not every leak is a sealant leak. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. When the fault is elsewhere, we say so instead of resealing for the sake of it. We are often asked to deal with products that weren’t meant for the joint and floor or wall movement joints that have failed, on mouldy bath & shower sealant, botched or over-sealed joints and expansion joints.
Homes around Sandhurst are mostly houses and cottages rather than flats. Sealant and grout wear out here just as they do anywhere: old material cut out, joints cleaned and a fresh finish laid.
You’re covered for a year from the day we finish. If anything is not right with it, call 0345 464 0079 or email us.

Can I do it myself?
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.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Surface by surface
Leaking trays & enclosures
A cracked tray, failed valve or leaking waste needs a different fix. We say so rather than reseal.
Mouldy bath & shower sealant
Mould that has grown into silicone does not clean out for good. All of it comes out, and the joint is treated and dried before anti-fungal sanitary silicone goes in.

Signs you need remedial sealant in Sandhurst
Joint depth matters. A bead bonded on three sides, or laid too thick, can’t flex, so it tears when the joint moves. Backing rod or bond-breaker tape prevents it.
Keep an eye out for these signs:
- Smears and lumps from a botched reseal
- Kitchen joints letting water behind the worktop
- Decorators’ caulk around a bath or shower
- Repeat leaks from the same joint
For an older house near a landmark such as Mission Church, older homes can move a little, which is hard on rigid grout and tired sealant.
What your quote should include
- Whether they’re fully insured
- How much experience the applicator has
- How long the guarantee is
- Whether they seal over old material or remove it
Leave it or put it right?
Repeat failures have a cause. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. In a small place like Sandhurst, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Looking after it afterwards
Aftercare is simple:
- Do not add new sealant on top of old
- Don’t point over movement joints
- Get the cause of a repeat leak found before resealing
- Keep bleach and abrasives off the bead
Leave the new joint to cure fully before it gets wet or moves: normally around 24 hours, or as long as we advise.
If a joint has failed more than once, stop resealing it. Get the cause found first, or the next bead will go the same way.

Sandhurst: your questions answered
Is Sandhurst within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Robertsbridge station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or email us and tell us about the property, and we’ll give you a clear price.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
How do I get a quote for remedial sealant in Sandhurst?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Is it messy?
Very little: the area around the joints is protected first, and we tidy up before we go.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do you fix expansion and movement joints?
Yes. We cut out the failed sealant, fit backing and reseal with a flexible product.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Remedial sealant around Sandhurst
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Letting a property close to Robertsbridge station? Then failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you look after a building such as Sandhurst Primary School, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.

How it works
Our applicators work methodically: 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. Somewhere as small as Sandhurst, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
