How we handle remedial sealant in Putney
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 work on mouldy bath & shower sealant, failed movement joints and shrunken worktop sealant, and common reasons people get in touch are sealant peeling off a dusty or damp surface and gaps opening along the back of the worktop.
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. A compact bathroom that steams up every day is hard on silicone and grout, and homes in Putney are no different.

Remedial sealant around Putney
London’s water is hard, which leaves limescale on sealant, grout and taps. In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early.
If you let a flat or house near Putney station, failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak. If you look after a building such as Our Lady of Victories Catholic Primary School, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.

- A tray or bath that’s cracked
- Plumbing leaks behind walls or under trays
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before you book.

Do you need remedial sealant in Putney?
All sealant wears out eventually. Mould grows into the silicone, the surface hardens and the bead shrinks, especially in damp, poorly aired rooms. At that point it has to come out.
Common reasons people contact us include:
- Black mould underneath the bead
- Leaks that keep coming back after resealing
- Beads that never stuck properly
- Torn expansion joints
Putney is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before you book
- How hidden problems are handled
- What guarantee comes with the work
- Is VAT in the price?
- What insurance they hold
Looking after it afterwards
After the cure time, these simple habits help:
- Don’t wait for a small gap to become a leak
- Ask why a joint failed before redoing it
- Do not point over movement joints
- Clean sealant with mild products only
Keep an eye on the joint at first, especially if movement was the problem. If anything changes, just call 0345 464 0079 or drop us an email.
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.
Why it’s worth doing now in Putney
Adding more sealant is the usual quick fix, and it rarely works. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Putney.
Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.
What you get with us

How the visit works
There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. In Putney, 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.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
Getting a quote
Getting a quote is simple: let us know the job and the location, and roughly how big it is. A few photos by email make the job easier to understand, and we’ll come back to you with a quote.

Surface by surface
Worktops & kitchens
If a worktop moves when you lean on it, the sealant will keep splitting. That needs refixing before resealing, and we will tell you if we find it.
Movement & expansion joints
Bonding on three sides is a common reason movement joints tear. Backing stops that, so the sealant grips the two sides only.
Questions from Putney
Is parking a problem for a job in Putney?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for landlords with property near Putney station?
Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Do you cover Putney?
Yes. We work in Putney and the rest of Greater London. For a quote, phone 0345 464 0079 or drop us an email.
What does remedial sealant cost?
Size, access and the old material all affect the cost. Call for a quick quote and we will talk you through it.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long does remedial resealing take?
Longer than a simple reseal, because every layer has to come out. For most joints, it’s a few hours, and we confirm the time with your quote.
Can I add another job to the visit?
Of course. Doing several areas at once is normally more efficient.
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.
