Collier Row Remedial Sealant
Removing failed, mouldy or leaking sealant and putting it right for Collier Row, backed by a one-year guarantee. Call for a quick quote.
- A shower that leaks however often it’s resealed
- Sealant peeling off a dusty or damp surface
- Gaps opening along the back of the worktop
Remedial sealant for homes and businesses in Collier Row
Movement and expansion joints fail when the sealant cannot stretch. We cut out the failed sealant and set the depth with backing, then a flexible sealant matched to the movement goes in. If you have gaps opening along the back of the worktop and leaks that keep coming back after resealing, we can put it right.
London homes include a lot of flats, conversions and mansion blocks, so a bathroom is often directly above a neighbour’s ceiling. In Collier Row, that’s a good reason to put tired sealant and grout right early.
Whatever the size of the job, it’s backed by our 12-month guarantee in Collier Row and across Greater London.

Different surfaces, different methods
Worktops & kitchens
Kitchen joints hold grease and residue, so cleaning takes longer than in a bathroom.
Mouldy bath & shower sealant
Mould can sit behind the silicone, not just in it. We treat the exposed joint once the bead is out so the new sealant starts clean.
DIY versus a professional finish
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
How we quote for remedial sealant
For a quick quote, just ask. The main things that affect it are:
- Working hours on commercial sites

What you pay reflects the work, not a rough estimate. That’s why we ask about the job first and give you a clear quote before any work starts.

When you contact us, these details help:

Related advice
What we are called out for in Collier Row
A lot of failed joints have been sealed over rather than replaced. New silicone cannot stick to the old bead, so the new layer peels, and damp and mould settle between them.
Most people get in touch when they notice something like this:
- Over-sealed joints coming away
- Products that weren’t meant for the joint
- Black mould underneath the bead
- A shower that leaks however often it’s resealed
For site and facilities teams at buildings such as Rise Park Infant School, we reseal washrooms and kitchens in schools and businesses as well as homes.
What to look for in a quote
- What product goes in the joint
- What the cure time is
- Are they insured?
- Who does the work, and how experienced they are
Keeping the joints in good condition
After the cure time, these simple habits help:
- Report a tray that rocks or a worktop that lifts
- Clean sealant with mild products only
- Check ceilings under showers for marks
- Never seal over old silicone
Keep the room ventilated: use the extractor or open a window after showering.
Leaks through failed sealant grow over time. Each use pushes more water behind the bead, into whatever is behind or below. Early action keeps it to a sealant job.
