About our remedial sealant in Puddle Dock
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. We’re often asked to deal with a shower that leaks however often it’s resealed and black mould underneath the bead, on expansion joints, shrunken worktop sealant and mouldy bath & shower sealant.
Across London, a large share of homes are flats, conversions or mansion blocks, and many bathrooms sit right above someone else’s ceiling. That makes worn sealant and cracked grout in Puddle Dock more than a cosmetic job.
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.

Your questions about remedial sealant in Puddle Dock
Could a tired shower seal in my Puddle Dock flat affect the neighbours below?
Yes, and the first sign is often a stain on the ceiling below. A proper reseal before the leak starts is the easy fix.
Can parking be tricky for a visit in Puddle Dock?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
Do you do commercial work?
Yes, regularly. Larger jobs can be planned room by room or area by area.
Can you quote for more than one area?
Yes, and it often makes sense. Combining jobs makes good use of the visit, so mention them when you ask for a quote.
Can tenants book the work?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do you work for letting agents?
Yes. We work in homes, commercial premises and hotels, and we are fully insured.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
Can I choose the sealant colour?
In most cases you can choose. We will explain which colours are available and agree one before we start.
What remedial sealant looks like in Puddle Dock
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. London has a lot of flats and conversions, and a failed shower or bath seal in one can show up on the ceiling below, so tired sealant is best dealt with early.
Puddle Dock is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Managing a site like The James Oglethorpe Primary School? Then we reseal washrooms and kitchens in schools and businesses as well as homes.

Do you need remedial sealant in Puddle Dock?
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
Common reasons people contact us are:
- Kitchen joints letting water behind the worktop
- Smears and lumps from a botched reseal
- Torn expansion joints
- Beads that never stuck properly
If you live in an older home near Moor Lane Church, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.

What affects the cost of remedial sealant
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- How many rooms, windows or areas are involved
- Any working-time requirements on site
- The size of the job
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Any previous sealing or DIY work
- How we’d reach the joints
- The address or postcode of the job
Every job is quoted individually, so start by telling us what you need. Just call 0345 464 0079 or send us an email with the details, and photos are welcome.
Should I try it myself first?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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.
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Look for stains below bathrooms now and then
- Don’t add new sealant on top of old
- Check trays and worktops do not move
- Never fill a movement joint with mortar or grout
Give the new sealant its full cure time: follow the cure time we give you.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Why it’s worth doing now in Puddle Dock
Another bead over the top will not fix a failed joint. It doesn’t grip the old layer, leaving the leak in place and one more layer to cut out later. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.

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 normally takes a few hours, depending on how many layers have to come out, depending on the amount of work. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. 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.
- Every layer of old sealant is cut and cleaned out.
- Next, any mould is treated and the joint dried.
- We use the right backing and sealant for any joint that moves.
- Finally we finish the joint and talk you through what we found.
How to prepare
- Mention if the joints have been sealed before
- Mention any leaks or damp you’ve noticed
- Keep pets and children clear of the area while we work
