How the job changes by surface
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, including the smears and film on surrounding tiles. Only a clean joint will take a new bead.
Movement & expansion joints
A movement joint must be able to stretch. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed with a low-modulus product.
Remedial sealant in Chelwood Common
Water on the floor doesn’t always mean failed silicone. Cracked trays, leaking wastes and faulty valves often look like a sealant problem. If that is what we find, we will tell you rather than reseal something that won’t fix it. Common call-outs are for sealant that came away because the surface wasn’t prepared and a second bead peeling off the first, across leaking tray & enclosure joints, failed movement joints and expansion joints.
In a village or hamlet like Chelwood Common, homes are often older cottages and farmhouses alongside a few newer houses. Movement in older walls and floors tends to show first as cracked grout or split sealant.
Our work is backed for twelve months, in Chelwood Common and everywhere else we cover.

Aftercare tips
After the cure time, these simple habits help:
- Always have old sealant cut out, not covered
- Report a tray that rocks or a worktop that lifts
- Keep the room well ventilated
- Check ceilings under showers for marks
Go easy on the new sealant: a mild cleaner and a soft cloth, with no blades or scourers.
Mould under a second layer of sealant keeps growing out of sight. When it finally shows, the whole bead needs to come out.
Why act early in Chelwood Common
Remedial work takes longer than a straight reseal, but not by much: it takes a few hours for most joints, depending on how much old sealant has to come out. Compared with chasing the same leak every few months, it’s time well spent. In a small place like Chelwood Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

What if resealing won’t fix my leak?

What does remedial sealant cost?

Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
Will there be a smell?
There can be a smell while the sealant cures. Opening a window helps.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What affects the quote in Chelwood Common
Call for a quick quote. What matters most is:
- The type of sealant required
- The old material and how stubborn it is
- Working hours on commercial sites
- Whether the work is at height
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
To help us quote quickly, please include:
- Whether it has been sealed before
- Where the job is, and your postcode
- Photos by email, if that is easy
- Any access issues, like height or stairs
There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or drop us an email.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Leaks from a shower valve, waste or pipework (a plumber’s job)
- Failed tanking or loose tiles behind the sealant
- Cracks in the fitting rather than the joint
If you’re not sure, just phone 0345 464 0079 or send us an email and we’ll give you a straight answer.

What else we do in Chelwood Common
DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Remedial sealant around Chelwood Common
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
If you look after a building such as Danehill Church of England Primary School, 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. Homes close to Chelwood Gate Church include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant.
