About our remedial sealant in Gordon Hill
Movement and expansion joints fail when the sealant cannot stretch. The old sealant comes out and backing goes in to control the depth, before resealing with a flexible product suited to the movement. If you have wide, uneven beads that look worse than the old ones and repeat leaks from the same joint, we can help.
Across London, a large share of homes are flats, conversions or mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. That makes worn sealant and cracked grout in Gordon Hill more than a cosmetic job.
A one-year guarantee comes as standard.

Questions from Gordon Hill
I let a flat near Gordon Hill station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Can parking be tricky for a visit in Gordon Hill?
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 fix expansion and movement joints?
Yes. The depth is set with backing so the sealant only bonds to the two sides.
Should I try DIY first?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
Are you insured?
Yes. We are fully insured for domestic and commercial work.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little.
How long does the work take?
It takes a few hours, depending on how many layers have to come out. You will know the timing when we quote.
Can you match the sealant colour?
Usually, yes. Sealants come in white, clear, grey and other colours, and we agree the colour with you before we start.
Why act early in Gordon Hill
Another bead over the top will not fix a failed joint. It can’t bond to what’s underneath, so the leak carries on and there’s now more to remove. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
What you get with us
- A 12-month guarantee on all work
- Anti-fungal silicone where joints get wet
- We agree the colour with you first
- Colour picked to suit the job

Signs you need remedial sealant in Gordon Hill
All sealant wears out eventually. Over the years it shrinks, hardens and gets colonised by mould, faster where ventilation is poor. Then the only fix is removal and a new bead.
These are the problems we’re asked about most:
- Black mould underneath the bead
- Gaps opening along the back of the worktop
- Leaks that keep coming back after resealing
- Over-sealed joints coming away
Gordon Hill is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Keep the room well ventilated
- Keep bleach and abrasives off the bead
- Act on a lifting corner right away
- Keep movement joints clear of mortar and paint
Clean gently: no scraping, scouring pads or harsh chemicals.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
The process
When we arrive, we look over the joints with you first, so there are no surprises. We protect the surfaces around the joints before any work starts. The work normally takes a few hours for most joints, depending on how much old sealant has to come out. 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.
- First we find out how and where the joint has failed.
- We strip the joint completely, removing any layers below.
- We clean the joint, treat any mould and let it dry.
- Moving joints get backing and a flexible sealant to suit.
- We tool the joint and tell you about anything else that needs attention.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- On commercial sites, let us know about site rules
- Tell us if parking is tricky

How the job changes by surface
Worktops & kitchens
Shrunken worktop sealant leaves a gap that lets water into the back edge. It’s cut out, degreased and resealed in a colour to suit.
Movement & expansion joints
A sealant stuck to the back of the joint cannot stretch. Backing stops that, so the sealant grips the two sides only.
Remedial sealant around Gordon Hill
London has hard water, which leaves limescale on sealant, grout and taps, and it has to be cleaned off before new sealant goes in. In a London flat, water from a failed bath or shower seal can reach the neighbours below, which is why it’s worth fixing early.
In the older streets around St Michael & All Angels, timber floors under older bathrooms flex, so joints need a sealant that moves with them. Rented homes near Gordon Hill station change hands often, and failed or mouldy sealant is worth putting right between tenancies, before it turns into a leak.
