When to call us in Trowley Bottom
Silicone doesn’t last for ever. Every shower, every splash and every wipe with a cleaner slowly wear it down, so its life depends on how the room is used, cleaned and aired.
Most people get in touch after spotting one of these:
- A messy, uneven bead from a previous reseal
- Gaps between the worktop and the wall
- Damp behind the bath or under the tray
- A reseal done over the top of the old bead
Rented homes near Harpenden station change hands often, and a reseal between tenants is a quick way to make the bathroom and kitchen look cared for.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
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 doesn’t work out, we can still put it right.
How it works
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take a couple of hours for a single bath or shower. Somewhere as small as Trowley Bottom, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint first and check for movement or leaks.
- 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, normally around 24 hours.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Clear items away from the joints we’re working on
- Mention any parking rules near the property

Why it’s worth doing now in Trowley Bottom
Sorting it now is quick: the work takes a morning or an afternoon for most single baths and showers. Left until water gets through, the job can grow to lifting panels, drying out and decorating. Around Trowley Bottom, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

What the job involves on each surface
Wet rooms
If a wet room leaks, the cause may be the tanking or the drain rather than the joints. We reseal the joints and will tell you if the water seems to be coming from somewhere else.
Basins & vanity units
The back of a basin gets wet every time someone washes. Corners behind basins are where mould tends to start, so it’s cut out and renewed just like a bath joint.

Bathroom resealing in Trowley Bottom: local notes
Most of the South East has hard water, so limescale builds up on sealant, grout and fittings.
In the older streets around Church of St Leonard, bathrooms in older houses have often been refitted more than once, with sealant laid over sealant. Schools such as Flamstead Village School 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 sealant work cannot fix
We’ll always be straight with you, so here’s what new sealant will not do:
- Water getting in through the grout rather than the sealant
- Water coming from the plumbing rather than the joint
- Cracks in the tray itself rather than the joint
