Remedial sealant in Stockbury, done properly
Water on the floor does not always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we’ll tell you rather than reseal something that will not fix it. If you have movement joints that have split or pulled away and over-sealed joints coming away, we can help, on botched or over-sealed joints, mouldy bath & shower sealant and failed movement joints alike.
Somewhere as small as Stockbury, homes tend to be cottages, farmhouses or converted buildings, with some newer houses too. Older walls and timber floors can move a little, and cracked grout and split sealant are often the first signs.
Big or small, you get the same 12-month guarantee in Stockbury and across Kent.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep movement joints clear of mortar and paint
- Use a soft cloth, not a scourer, on silicone
- Have loose fittings fixed before resealing
- Always have old sealant cut out, not covered
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just ring 0345 464 0079 or send us an email.
Mould under a second layer of sealant keeps growing out of sight. By the time it shows through, the joint is well past saving.
Stockbury: your questions answered
Can you help a landlord with a rental near Newington station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can ring 0345 464 0079 or send us an email with the details for a clear quote.
Can you do remedial sealant in Stockbury?
Yes, Stockbury is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing.
What happens if the problem is the tray or the plumbing?
We check for that before we reseal. If we find the leak is elsewhere, we tell you before going further.
How long will it take to strip and reseal the joint?
Allow a few hours, depending on how many layers have to come out. You will know the timing when we quote.
Do I need to be at home?
That depends on where the joints are. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
Is remedial work guaranteed?
Yes. Our one-year guarantee covers the work, and we are ARBOMaster approved.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you take off two layers of silicone?
Yes. We remove every layer; over-sealing fails because silicone won’t bond to silicone.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Honest limits
Honest advice matters more to us than a booking, so here’s what sealant can’t fix:
- Sealant in an older building that needs testing for asbestos first
- A cracked shower tray or bath (that needs repair or replacing)
- Movement from fittings that are not supported
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before booking.
Joints and surfaces we work on

How the visit works
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours, depending on how many layers have to come out. Somewhere like Stockbury needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work out whether the problem is the sealant, movement or a leak.
- Each layer is cut out and the residue cleaned off.
- Mould is treated and the joint dried.
- The right product goes in, with backing where the joint moves.
- The joint is tooled and you’re told about anything else we found.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Clear items away from the joints we’re working on
- Tell us about any previous sealing or DIY attempts

Related advice
Why deal with it now?
Mould under a bead can’t be reached by cleaning. The layers have to come out, so the joint can be treated and resealed. In a small place like Stockbury, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.
Why Stockbury clients choose us

- One-year guarantee on every job
- Arbo and Everbuild products
- Experience in homes, commercial sites and hotels
When to call us in Stockbury
Joint depth matters. A bead bonded on three sides, or laid too thick, cannot flex, so it tears when the joint moves. Backing sets the depth and stops that.
If you can see any of these, it’s time to have the joints looked at:
- Thick, messy sealant smeared over tiles
- Products that weren’t meant for the joint
- Black mould underneath the bead
- Gaps opening along the back of the worktop
If you live in an older home near St Mary Magdalene Church, walls and floors in older homes can move, and sealant and grout show it first.
Questions to ask before you book
- What preparation is included
- How much experience the applicator has
- What guarantee comes with the work
- Whether VAT is included
Different surfaces, different methods
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing rod or bond-breaker tape prevents it, letting the sealant flex between the two faces.

Remedial sealant in Stockbury: local notes
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.
For landlords with property near Newington station, botched sealant from a previous quick fix is easier to strip out between tenants.
