Rotherhithe Remedial Sealant
We cover Rotherhithe for removing failed, mouldy or leaking sealant and putting it right. Old sealant removed completely, joints prepared properly and a 12-month guarantee.
- Movement joints that have split or pulled away
- A shower that leaks however often it’s resealed
- Thick, messy sealant smeared over tiles
What sealant work can’t fix
Sealant isn’t the answer to every problem, and we’ll tell you before work begins. Sealant won’t put right:
- A bath, tray or worktop that moves until it’s properly fixed
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Water damage behind tiles that needs a tiler
If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.
Where we work in Rotherhithe

About our remedial sealant in Rotherhithe
A movement joint stops working when its sealant splits or sets hard. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. If you have worktop sealant that has shrunk and split and beads that never stuck properly, we can put it right.
Much of London’s older housing is Victorian and Edwardian terraces, many of them now split into flats, with bathrooms fitted into whatever space was available. Small, steamy rooms are where mould gets into sealant and grout fastest, and homes in Rotherhithe are no different.
We stand behind the work with a 12-month guarantee, so you are not left on your own once the job is done.

Do you need remedial sealant in Rotherhithe?
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
The most common problems we see are:
- Torn expansion joints
- Beads that never stuck properly
- Over-sealed joints coming away
- Products that weren’t meant for the joint
Rented homes near Canada Water station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.

What the job involves on each surface
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Windows & doors
A frame that keeps leaking may not be the mastic. If the frame joint isn’t the cause, we’ll say so.

What we do, step by step
Before we leave, we go over the finished joints with you and explain the cure time. The visit itself generally takes a few hours, depending on how many layers have to come out, depending on how much there is to do. In Rotherhithe, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We look at how the sealant has failed and check for movement or a leak path.
- We strip the joint completely, removing any layers below.
- Next, any mould is treated and the joint dried.
- Where the joint moves, backing and a flexible sealant suited to the movement go in.
- The new joint is tooled neatly and we explain anything else we found.
How to prepare
- Tell us if parking is tricky
- Mention if the joints have been sealed before
- Tell us about any water getting in

Advice
FAQs for Rotherhithe
Can worn sealant in a flat in Rotherhithe cause a leak downstairs?
It can, yes: water that gets past a split bead or cracked grout often runs under the tray and shows on the ceiling below. Replacing the sealant and grout before that happens is much less trouble than repairing a neighbour’s ceiling.
Do you work for landlords with property near Canada Water station?
Yes, we work for letting agents and landlords. Just phone 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
Will the old sealant be removed?
Yes, every time. New sealant will not bond properly to old, so the joint is cleaned back first.
What if the leak isn’t the sealant?
We will tell you. If it’s a cracked tray, a failed valve or a leaking waste, resealing will not fix it, so we will not pretend it will.
Do you guarantee remedial jobs?
Yes. You get our 12-month guarantee, and we’re fully insured.
Can you do several jobs on one visit?
Yes. Just list everything you need.
Landlords, agents and businesses in Rotherhithe
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
For anyone letting property in or around Rotherhithe, several properties can go on one quote. Send us the addresses and the work at each, and photos by email help.
How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Act on a lifting corner straight away
- Look for stains below bathrooms now and then
- Report a tray that rocks or a worktop that lifts
- Ask why a joint failed before redoing it
Clean gently: no scraping, scouring pads or harsh chemicals.
Movement joints that have split let water into the structure, and left long enough, the edges of the joint can crumble. Resealing while the edges are sound is simpler.
