How remedial sealant works in City of London
If a joint has been resealed and is leaking again, it’s worth a proper look. Send pictures when you ring 0345 464 0079 or send us an email, along with when it was last resealed. We work on expansion joints, failed movement joints and mouldy bath & shower sealant, and the jobs we see most are torn expansion joints and wide, uneven beads that look worse than the old ones.
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a typical bath or shower, longer where several layers have been applied.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- Once dry, a suitable sealant is applied and tooled.
- We give you the cure time and explain what caused the failure.
What you will pay
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Bathrooms and kitchens across City of London
Our remedial sealant work across City of London covers homes, rentals and businesses, in City of London and well beyond. Wherever the job is, all the old material comes out before anything new goes in.
Hard water across most of the South East leaves limescale on sealant, grout and fittings. Whatever the job in City of London, surfaces are cleaned back properly before new sealant goes in.
City of London: If you live in an older home near St Olave Old Jewry, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. For site and facilities teams at buildings such as Fashion Retail Academy, its toilets, changing areas and kitchens need their sealant renewed like any other building’s.
How the job changes by surface
Movement & expansion joints
Some movement joints have been filled with mortar or grout. Where it can be raked out, we replace it with flexible sealant.
Leaking trays & enclosures
When failed joints are the cause, they’re all cut out and renewed, tray edges and screen profiles included.
When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Old mastic in a building from before 2000 that should be checked for asbestos before it’s disturbed
- A tray or bath that’s cracked
- Water damage behind tiles that needs a tiler
Aftercare tips
Good habits help new joints last longer. Our tips:
- Never fill a movement joint with mortar or grout
- Have loose fittings fixed before resealing
- Check ceilings under showers for marks
- Ask why a joint failed before redoing it
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
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.
Why deal with it now?
Hidden water does the most damage: wet floors, stained ceilings and swollen worktops. By comparison, sorting the joint is quick.

Will you leave a mess?

How long will it take to strip and reseal the joint?
It takes a few hours for most joints, depending on how much old sealant has to come out. We’ll give you a timescale when we quote.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
