What happens on the day
There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of rooms in most cases. For a village or hamlet like Ashendon, 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.
- We agree a programme with you: which rooms, in what order, at what times.
- We go through your site’s paperwork needs, such as RAMS, before work begins.
- Old sealant is cut out room by room and joints cleaned and treated.
- Anti-fungal sanitary silicone goes into wet areas, with suitable sealant elsewhere.
- Each finished area is checked with you and given a cure time.
Preparing for the visit
- For business premises, tell us about site rules or sign-in
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts

Related advice
Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Aftercare tips
Good habits help new joints last longer. Our tips:
- Encourage users to squeegee shower walls
- Act on lifting sealant before it leaks
- Schedule work around occupancy
- Keep strong chemicals and scourers off the joints
Make it easy for staff to flag a failing joint. Catching one split early can save a leak later.
Signs to look for: mould, splits, peeling corners or water marks downstairs. When you see them, it’s time to plan a reseal.
When to call us in Ashendon
Heavy use means more movement: people of all sizes, daily cleaning and constant loading. A tray that isn’t fully supported soon tears its seal.
It’s worth asking for a quote if you see:
- Mouldy bathrooms flagged at a tenancy check
- Leaking joints in shower rooms and changing areas
- Shower leaks reaching the floor below
- Silicone laid over old silicone by a previous contractor
