Bathroom resealing in Middle Assendon
It isn’t only bathrooms. Worktop upstands, sink edges and splashback joints get wet every single day, and water that gets into the back edge of a worktop can swell the board. We reseal them with a kitchen-suitable silicone, matched to the worktop where it’s on show. If you are dealing with a messy, uneven bead from a previous reseal and water getting behind the kitchen upstand, we can put it right, on kitchen worktops & upstands, shower trays & enclosures and basins & vanity units alike.
Homes around Middle Assendon are mostly houses and cottages rather than flats. The work is the same as anywhere: old material cut out, joints cleaned and a fresh finish laid.
Each job carries a 12-month guarantee, whatever its size.

Why it’s worth doing now in Middle Assendon
A failed joint gets more costly to put right the longer it’s left. Once water is behind the bath, it can reach floorboards, panels and the ceiling underneath, and that is a far bigger job than a reseal. Around Middle Assendon, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Surface by surface
Basins & vanity units
Vanity units have long, worktop-style joints against the wall. Water that gets behind can damage the unit, so the joint is sealed in one unbroken line.
Kitchen worktops & upstands
Kitchen joints need more degreasing than bathroom ones, because cooking grease stops sealant bonding. Proper degreasing is what helps the new joint last.
Common problems we fix in Middle Assendon
Silicone does not last for ever. Daily water, heat and cleaning products take their toll over the years, and how long it lasts comes down to use, cleaning and ventilation.
Keep an eye out for these signs:
- Cracked, shrunken or lifting silicone
- Lumpy, uneven sealant from a DIY attempt
- Black spots spreading through the bead
- Water getting behind the bath panel
If you live in an older home near Church of St James, timber floors under older bathrooms flex, so joints need a sealant that moves with them.

How the visit works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a couple of hours for a single bath or shower. In a small place like Middle Assendon, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First the area is protected and every bit of old sealant removed, including the film left on the tiles.
- Next, the joint is cleaned and any mould is treated.
- Once it’s dry, any bath is filled so the bead is laid with it at its heaviest.
- A single bead of anti-fungal sanitary silicone is applied and tooled smooth.
- Finally we tidy up and explain the cure time before we leave.
How to prepare
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
