About our remedial sealant in Finsbury
A joint that keeps failing usually has a reason. Movement, the wrong product or a leak from somewhere else will beat any new bead. Finding that cause comes before any new sealant. We’re often asked to deal with wide, uneven beads that look worse than the old ones and sealant that came away because the surface wasn’t prepared, on shrunken worktop sealant, leaking tray & enclosure joints and expansion joints.
Hard London water leaves limescale on sealant, grout and taps alike. In Finsbury, remedial sealant is as much about a room looking cared for as about keeping water out.
All of our work is guaranteed for twelve months, in Finsbury and everywhere else we cover.

What affects the quote in Finsbury
We quote each job individually. This is what makes a difference:
- How easy the joints are to reach
- Any mould that needs treating
- The number of rooms or windows
- The type of sealant required
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, and we’ll explain the quote if you ask.
What to tell us for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Pictures of the joints, sent by email
- The problem you’ve noticed
- Whether it has been sealed before
- Any access issues, like height or stairs
There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To get started, phone 0345 464 0079 or email us.
How it works
There’s no need to move everything out, just the space around the work. We protect the rest, and the job takes a few hours for most joints, depending on how much old sealant has to come out for a typical job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Finsbury. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Preparing for the visit
- Mention any tricky access
- Mention any parking rules near the property
- Tell us about any water getting in
Getting a quote
We quote each job on its own, so start by telling us what you need. Just ring 0345 464 0079 or send us an email with the details and send photos if you have them.

FAQs for Finsbury
Could a tired shower seal in my Finsbury flat affect the neighbours below?
Yes. In a flat, water from a failed bath or shower seal has only one way to go, and that’s down. A proper reseal before the leak starts is the easy fix.
Is parking a problem for a job in Finsbury?
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.
Does remedial work come with a guarantee?
Yes, for 12 months. Where we’ve flagged another fault, it needs fixing for the joint to last.
Can failed expansion joints be resealed?
Yes. If a joint has been filled with mortar or rigid filler, we rake it out where possible, then the joint is sealed properly.
Can you work on commercial sites?
Yes, regularly. Larger jobs can be planned room by room or area by area to suit the site.
Do you come to Finsbury?
Yes. We’re based in Crawley and work across South East England, London and Scotland.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional.
How long does the work take?
The number of joints and layers decides it. We will tell you before any work starts.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t point over movement joints
- Check trays and worktops don’t move
- Never seal over old silicone
- Do not wait for a small gap to become a leak
Keep the room ventilated: use the extractor or open a window after showering.
Warning signs: sealant lifting at the ends, a second bead visible on top of the first, black mould under the silicone, or stains below a bathroom. Any of them means it’s time for remedial work.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Bathrooms and kitchens in Finsbury
In a London flat, water from a failed bath or shower seal can reach the neighbours below, so tired sealant is best dealt with early. Finsbury has hotels and guest accommodation nearby. As well as homes, we work in hotel bathrooms, where resealing and regrouting can be done room by room.
Letting a property close to Old Street station? Then botched sealant from a previous quick fix is easier to strip out between tenants. If you live in an older home near Jewin Welsh Presbyterian Chapel, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

When it is not the sealant
We will always be straight with you, so here’s what sealant cannot fix:
- Tiles that have come away from the wall
- A cracked shower tray or bath (that needs repair or replacing)
- A leaking trap, valve or supply pipe
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.
Joints and surfaces we work on
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
- Mouldy bath & shower sealant
- Shrunken worktop sealant
- Failed movement joints
Different surfaces, different methods
Worktops & kitchens
Kitchen joints hold grease and residue, so we spend extra time cleaning.
Over-sealed & botched joints
Previous removal attempts can leave scratches or gouges. We work carefully to avoid adding to it, and tell you about any damage we find.
Signs you need remedial sealant in Finsbury
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.
Signs it’s time to call us include:
- Kitchen joints letting water behind the worktop
- Movement joints that have split or pulled away
- Sealant applied over old sealant that has lifted
- Beads that never stuck properly
For site and facilities teams at buildings such as Prior Weston Primary School and Children's Centre, washroom and kitchen sealant there needs the same care as at home, and schools and businesses are part of our work as well as homes.
