Remedial sealant in Covent Garden, done properly
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint fails however neatly it’s applied. We take it out and use a sealant made for that joint. We work on failed movement joints, mouldy bath & shower sealant and botched or over-sealed joints, and people most often call us about mould trapped under a layer of silicone and a second bead peeling off the first.
Hard London water leaves limescale on sealant, grout and taps alike. In Covent Garden, remedial sealant is as much about a room looking cared for as about keeping water out.
Every job comes with our 12-month guarantee.

How we quote for remedial sealant
There’s no set price list, because jobs vary so much. What we look at:
- Working hours on commercial sites
- The number of rooms or windows
- Access and height
- Whether old sealant or filler has to be cut out
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

FAQs for Covent Garden
Is parking an issue for remedial sealant in Covent Garden?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.
Could a tired shower seal in my Covent Garden 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.
Is it worth trying it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Can you reseal a split movement joint?
Yes. Failed movement joints are cut out and resealed with backing and a flexible sealant suited to the movement.
Do you remove the old sealant?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Someone sealed over the old bead. Can you fix it?
Yes. Stripping layered sealant takes longer than a normal reseal, but it’s the only way the new joint will last.
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.
Do you work in Covent Garden?
Yes. We work in Covent Garden. To book, call 0345 464 0079 or send us an email.
Covent Garden 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. There are hotels and other places to stay in and around Covent Garden. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Covent Garden is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you live in an older home near Crown Court Church, older homes can move a little, which is hard on rigid grout and tired sealant.

Looking after it afterwards
Aftercare is simple:
- Keep the room well ventilated
- Do not add new sealant on top of old
- Keep bleach and abrasives off the bead
- Keep movement joints clear of mortar and paint
Watch the joint over the first few weeks, especially if movement was the problem. If anything changes, just call 0345 464 0079 or send us an email.
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.
The process
A visit follows a simple pattern: we check the joints, protect the area around them, do the work and clear up. It normally takes a few hours, depending on how many layers have to come out. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Covent Garden. A visitor permit or a nearby bay makes the visit run more smoothly.
- We protect the surfaces around the joint.
- Every layer of failed sealant is stripped out.
- We clean and degrease the joint and look for signs of movement or water.
- New sealant goes in once the joint is dry, and is tooled smooth.
- We give you the cure time and explain what caused the failure.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any previous sealing or DIY attempts
- Mention any tricky access

Different surfaces, different methods
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning.
Over-sealed & botched joints
Botched joints sometimes have damaged edges from earlier scraping. We work carefully to avoid adding to it, and point out any existing damage.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Common problems we fix in Covent Garden
Some joints fail because water is reaching them from behind. A leaking valve, a failed waste or cracked grout feeds water behind the bead, so the silicone goes mouldy or lets go.
People generally contact us after spotting one of these:
- Black mould underneath the bead
- Worktop sealant that has shrunk and split
- Products that weren’t meant for the joint
- A second bead peeling off the first
For landlords with property near London Charing Cross station, botched sealant from a previous quick fix is easier to strip out between tenants.
