- Sealant that never bonded to the surface
Aftercare tips
Aftercare is simple:
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
- Act quickly if a seal starts to leak
- Open a window or run the fan after bathing
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black saves a harder job later.
New build mastic in Minnow End
A new house keeps drying out and settling for its first couple of years. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include messy sealant that spoils new finishes and sealant applied over dusty or wet surfaces, across plot handovers, bathrooms & en suites and kitchens.
Somewhere as small as Minnow End, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
All of our work is guaranteed for twelve months.

What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
Skirting and floors
Wet-area floor joints need a flexible seal. We seal them with a sealant suited to wet areas.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
When it is not the sealant
We’ll always be straight with you, so here’s what sealant can’t fix:
- Leaking fittings rather than failed sealant
- Structural cracks in walls or ceilings
- A tray or bath that isn’t properly supported, until it’s fixed
If in doubt, ring 0345 464 0079 or drop us an email and we’ll say what we think.

How the visit works
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes anything from a few hours to several days, depending on the number of plots, and the area is left clean. Somewhere as small as Minnow End, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each joint is checked for movement before we start.
- We remove the failed sealant and clean the joints.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Before we arrive
- Mention any sign-in or site rules at work premises
- Mention any parking rules near the property
- Mention if the joints have been sealed before
