How it works
The work is kept neat and contained to the area we are working on, so you can carry on as normal. Expect the work to take a few hours for a typical bath or shower, longer where several layers have been applied, and we explain the cure time before we leave. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Bounds Green. A visitor permit or a nearby bay makes the visit run more smoothly.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- The joint is cleaned, treated for mould and left to dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
How to prepare
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on
- Tell us about any previous sealing or DIY attempts

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
Bounds Green: your questions answered
Can worn sealant in a flat in Bounds Green cause a leak downstairs?
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 you help a landlord with a rental near Bowes Park station?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or send us an email with the details for a clear quote.
Can you fix a reseal that hasn’t worked?
Yes. There’s generally a reason: sealant over sealant, movement or another leak, and we deal with the cause first.
Do you work in Bounds Green?
Yes. We are based in Crawley and work across South East England, London and Scotland, Bounds Green included.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We’ll tell you what we are using and why.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it does not work out, we can redo it.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Do you guarantee remedial jobs?
Yes, with our one-year guarantee. If we have pointed out another problem, getting it fixed helps the new joint last.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Find out why the sealant failed first
- Act on a lifting corner straight away
- Keep movement joints clear of mortar and paint
- Keep the room well ventilated
Leave the new joint to cure fully before it gets wet or moves: generally 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.
Bounds Green homes and their sealant
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, which is why it’s worth fixing early.
Managing a site like Bounds Green Infant School? Then we reseal washrooms and kitchens in schools and businesses as well as homes. As a London address, Bounds Green can be tricky for parking: let us know about parking bays, permits or a driveway.

Your quote is based on your job. We take into account:
- How much there is to do

Photos by email are helpful but not essential. Try to tell us:

Why deal with it now?
Mould under a bead cannot be reached by cleaning. Removal is the only way to get at it, and the joint treated and dried before resealing. In a flat in Bounds Green, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.

What else we do in Bounds Green
When to call us in Bounds Green
Water from somewhere else can ruin a good seal. A slow leak behind the tiles soaks the joint from the back, so the silicone goes mouldy or lets go.
Any of these means the joints need attention:
- Over-sealed joints coming away
- Torn expansion joints
- Dark patches showing through the sealant
- Sealant peeling off a dusty or damp surface
Letting a property close to Bowes Park station? Then a joint that keeps failing is best fixed properly while the property is empty.
