Bathroom resealing in Knowl Hill, done properly
The bead of silicone around a bath, tray or worktop is what keeps water out of the gaps. Once it cracks or goes mouldy, water starts to find its way through. Every trace of the old sealant is taken out and replaced with anti-fungal sanitary silicone. If you have water getting behind the bath panel and water getting behind the kitchen upstand, we can help, on basins & vanity units, sinks & splashbacks and baths alike.
Homes around Knowl Hill 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.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Give the silicone its full cure time
- Keep scourers and sharp tools away from the bead
- Squeegee the walls and tray after use
- Keep the fan on for a while after bathing
Check the sealant now and then. A small split or a corner lifting is easy to spot, and if anything looks wrong, just call 0345 464 0079 or drop us an email.
Watch for the early signs: lifting ends, gaps, dark shadows under the bead or a stain downstairs. Any of these means the joint needs attention.
How the visit works
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a couple of hours for a single bath or shower. For a village or hamlet like Knowl Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- First, each joint is checked for movement and signs of water.
- Every trace of the old bead is removed, including the thin smear on the tiles.
- The joint is cleaned, degreased and treated for mould.
- With the joint dry, and any bath loaded with water, a single bead of anti-fungal silicone is applied.
- The bead is tooled smooth and you are told the cure time, generally around 24 hours.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Tell us about access, such as stairs, a lift or high-level joints

Surface by surface
Shower trays & enclosures
The vertical joint where a screen profile meets the wall is a common leak point. We reseal it along with the base of the enclosure, sealing the side the enclosure’s instructions call for.
Wet rooms
Wet rooms rely on sound joints at floor and wall junctions. They’re resealed with anti-fungal sanitary silicone, working on the surface joints, not the tanking or drainage.
Bathroom resealing around Knowl Hill
Most of the South East has hard water, which leaves limescale on sealant, grout and fittings.
Homes close to Saint Peter include some older properties, and bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Rented homes near Wargrave station change hands often, and mouldy sealant is one of the first things a new tenant notices, so it’s worth renewing between lets. Schools such as Knowl Hill Church of England Primary Academy are buildings too, and 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.

What happens if it’s left?
A quick bead over the top of the old one might look better for a while, but it will not bond. It lifts, traps water and grows mould behind it, so the next person has twice as much to remove. Older cottages and farmhouses around Knowl Hill can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

- A cracked shower tray or bath (that needs repair or replacement)

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
