Remedial sealant in Slough Green
Removing failed sealant is the hardest part of the job. Every layer is cut out, the residue cleaned off and the joint degreased, without scratching tiles, trays or frames. Only then can new sealant bond. Common call-outs are for decorators’ caulk around a bath or shower and repeat leaks from the same joint, across failed movement joints, leaking tray & enclosure joints and expansion joints.
In a village or hamlet like Slough Green, 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.
All our work is covered by a one-year guarantee.

What happens if it’s left?
Remedial work takes longer than a straight reseal, but rarely a lot: it takes a few hours, depending on how many layers have to come out. Compared with chasing the same leak every few months, it’s time well spent. Around Slough Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Can I do it myself?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
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, then guaranteed for a year.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Always have old sealant cut out, not covered
- Never fill a movement joint with mortar or grout
- Keep bleach and abrasives off the bead
- Find out why the sealant failed first
Keep the room ventilated: use the extractor or open a window after showering.
Mould trapped under over-sealed joints spreads unseen. When it finally shows, the whole bead needs to come out.
How the visit works
We work through the job in order: protect, prepare, seal, tidy. Typically it takes a few hours for most joints, depending on how much old sealant has to come out, and the area is left clean. Somewhere like Slough Green needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- Surrounding tiles, trays and frames are protected first.
- Every layer of failed sealant is stripped out.
- The joint is degreased and checked for movement and leaks.
- 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.
How to prepare
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Tell us about access, such as stairs, a lift or high-level joints

How we quote for remedial sealant
There’s no set price list, because jobs vary so much. The quote depends on:
- Whether there’s mould to deal with
- Working hours on commercial sites
- How much old sealant there is and how hard it is to remove
- How much there is to do
The cost reflects the work involved, not guesswork. That is why we ask about the job first.

- A few photos by email, if you can

Different surfaces, different methods
Over-sealed & botched joints
Every layer has to come out, including the smears and film on surrounding tiles. New sealant needs a fully clean surface.
Movement & expansion joints
Movement joints in floors, walls and façades need a flexible sealant set to the right depth. Failed sealant is cut out, backing rod or tape is fitted and the joint resealed.
