About our remedial sealant in Chesham Bois
Decorators’ caulk in a shower, bathroom silicone on a window, a rigid filler in a movement joint will not last, however tidy it looks. We take it out and use a sealant made for that joint. We work on mouldy bath & shower sealant, botched or over-sealed joints and failed movement joints, and common reasons people get in touch are movement joints that have split or pulled away and over-sealed joints coming away.
Even in a smaller place like Chesham Bois, bathrooms and kitchens see heavy daily use. Older or newer, every room gets the same approach: old sealant or grout cut out, joints cleaned and dried, and a fresh finish laid.
Your job is guaranteed for a year, as with all our work.

Different surfaces, different methods
Mouldy bath & shower sealant
Repeat mould usually points to a damp, poorly aired room. Along with resealing, we’ll mention if the room needs better ventilation.
Over-sealed & botched joints
A botched joint can hide two or three layers of sealant, and silicone residue is cleaned off the tiles too. Only a clean joint will take a new bead.
For landlords and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
We also work for property managers and facilities teams. Several sites can go on one quote, and we’re fully insured.
Chesham Bois questions
I let a flat near Amersham station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Do you work for hotels and guest houses in Chesham Bois?
Yes, hospitality work, including hotels, is part of what we do. Jobs can be programmed room by room, with out-of-hours working possible to arrange.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
Do the sealants smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
What happens if the problem is the tray or the plumbing?
We check for that before we reseal. If the fault is elsewhere, you will know before any work is done.
Is it worth trying it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
How long should I leave it?
Many sealants skin over quickly but take longer to cure fully. We will give you the cure time for the product we used.
When to call us in Chesham Bois
Silicone only bonds to surfaces that are clean and dry. Soap film, dust, damp or old residue stop it gripping, and the joint starts to come away early.
Common reasons people contact us include:
- A second bead peeling off the first
- Smears and lumps from a botched reseal
- Beads that never stuck properly
- Leaks that keep coming back after resealing
Homes close to Church of St Leonard include some older properties, and timber floors under older bathrooms flex, so joints need a sealant that moves with them.
Before booking anyone
- Whether all the old sealant comes out first
- How the colour is chosen
- The length of the guarantee
- How hidden problems are handled
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- A bath, tray or worktop that moves until it’s properly fixed
- Plumbing leaks behind walls or under trays
- Failed tanking or loose tiles behind the sealant
If you’re not sure, just phone 0345 464 0079 or drop us an email and we’ll give you a straight answer.
Surfaces we seal
- Shrunken worktop sealant
- Failed movement joints
- Botched or over-sealed joints
- Leaking tray & enclosure joints
- Expansion joints
- Mouldy bath & shower sealant
What happens if it’s left?
DIY removal often leaves scratches and a film of residue, and the residue left behind stops the next bead bonding. Careful stripping is where most of our time goes. In a smaller place like Chesham Bois, wherever a wall is exposed, a failed outside joint is a real source of damp. Inside, a split seal lets water into floors and panels just as it would anywhere.
We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What we do, step by step
The work is kept neat and contained to the joints we are treating. The job generally takes a few hours for a typical bath or shower, longer where several layers have been applied. In a smaller place like Chesham Bois, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we work out whether the problem is the sealant, movement or a leak.
- Old beads and residue are removed down to clean surfaces.
- Mould is treated and the joint dried.
- We reseal with a product suited to the joint, backed where needed.
- We finish neatly and point out anything that needs another trade.
Getting ready for the visit
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work
- For indoor joints, keep the area dry beforehand if you can

Related advice
DIY sealant or a professional job?
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.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
