Remedial Sealant in Alscot
Failed sealant joints in Alscot need attention? We cut out the old, prepare the joints and apply the right sealant.
- Thick, messy sealant smeared over tiles
- Sealant peeling off a dusty or damp surface
- Repeat leaks from the same joint
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Clean sealant with mild products only
- Do not point over movement joints
- Ask why a joint failed before redoing it
- Keep an eye on the ceiling below the bathroom
If we have found a cause, such as a loose tray or a leaking waste, get it fixed, or the new joint may fail again.
Warning signs: peeling layers, mould showing through the bead, leaks after showering or cracks in a movement joint. Any of them means it’s time for remedial work.
Remedial sealant in Alscot, done properly
In Alscot, as anywhere, remedial jobs tend to look alike: over-sealed joints, hidden mould, repeat leaks and split movement joints. Each is stripped back and done again properly. We work on shrunken worktop sealant, expansion joints and failed movement joints, and the jobs we see most are over-sealed joints coming away and smears and lumps from a botched reseal.
Being in a small place like Alscot makes no difference to the job itself: the journey and access are simply agreed in advance. Once we’re there, the bathroom or kitchen gets the same care as anywhere else.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

What we’re called out for in Alscot
Joints that move need sealant that can stretch. Flexing baths, rocking trays and building movement joints will split a rigid or thin bead.
The most common problems we see are:
- Mould trapped under a layer of silicone
- Smears and lumps from a botched reseal
- Worktop sealant that has shrunk and split
- Repeat leaks from the same joint
If you let a flat or house near Monks Risborough station, botched sealant from a previous quick fix is easier to strip out between tenants.
What your quote should include
- What insurance they hold
- When the joint can take water or movement
- Is VAT in the price?
- Whether you can choose the colour
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours, depending on how many layers have to come out, and the area is left clean. Somewhere like Alscot needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we find out how and where the joint has failed.
- All the old sealant comes out, including any layers underneath.
- The joint is cleaned, treated for mould and left to dry.
- We use the right backing and sealant for any joint that moves.
- The new joint is tooled neatly and we explain anything else we found.
Getting ready for the visit
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Move anything stored near the joints

Advice
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Remedial sealant around Alscot
Hard water is the norm across most of the South East, which leaves limescale on sealant, grout and fittings, and it has to be cleaned off before new sealant goes in.
Schools such as Princes Risborough Primary School are buildings too, and its toilets, changing areas and kitchens need their sealant renewed like any other building’s. In the older streets around St Teresa's Church, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

Why it’s worth doing now in Alscot
A joint that has failed twice will fail again unless the cause is dealt with. Taking time to find the cause, whether it’s movement, a leak or the wrong product, is what stops it happening again. Around Alscot, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
