Movement and expansion joints fail when the sealant can’t stretch. We cut out the failed sealant and set the depth with backing, before resealing with a flexible product suited to the movement. Typical jobs include gaps opening along the back of the worktop and decorators’ caulk around a bath or shower, on leaking tray & enclosure joints, shrunken worktop sealant and botched or over-sealed joints.

What remedial sealant looks like in Three Mile Cross
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings.
Homes close to St Michael and All Angels include some older properties, and older homes can move a little, which is hard on rigid grout and tired sealant.

Why act early in Three Mile Cross
Spraying mould remover on a sealed-over joint doesn’t reach what’s underneath. The layers have to come out. Around Three Mile Cross, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

Do you need remedial sealant in Three Mile Cross?
Using the wrong product is a common cause: acrylic caulk in a wet area, a general-purpose sealant on a moving joint, or an acetoxy silicone on natural stone or some metals. None of them last.
Look out for any of the following:
- Smears and lumps from a botched reseal
- Dark patches showing through the sealant
- Sealant peeling off a dusty or damp surface
- A shower that leaks however often it’s resealed
Letting a property close to Reading Green Park station? Then a joint that keeps failing is best fixed properly while the property is empty.
What to look for in a quote
- Whether they’re fully insured
- Whether VAT is included
- Whether all the old sealant comes out first

How to look after the new joints
After the cure time, these simple habits help:
- Report a tray that rocks or a worktop that lifts
- Check ceilings under showers for marks
- Always have old sealant cut out, not covered
- Find out why the sealant failed first
Go easy on the new sealant: no scraping, scouring pads or harsh chemicals.
A failing joint rarely gets better on its own. Every shower or downpour sends more water through, into floors, walls or ceilings. Early action keeps it to a sealant job.
What we do, step by step
Once we’re on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. Most jobs then take a few hours, depending on how many layers have to come out. For a village or hamlet like Three Mile Cross, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- The failure is looked at first, so we know whether it’s sealant, movement or water from elsewhere.
- Old beads and residue are removed down to clean surfaces.
- We treat any mould and dry the joint thoroughly.
- We reseal with a product suited to the joint, backed where needed.
- The joint is tooled and you’re told about anything else we found.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Clear the area around the work
- Where the joints are inside, avoid wetting them before we arrive
