- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
- New-build shower sealant that has already split
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is.
If you’ve already had a go yourself, that is fine. We cut it out and start again.
About our new build mastic in Winkfield Street
Across Winkfield Street, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. We work on show homes, windows & doors and plot handovers, and the jobs we see most are sealant applied over dusty or wet surfaces and plot mastic for developers ahead of handover.
Somewhere as small as Winkfield Street, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
Whatever the size of the job, you get the same one-year guarantee.

How it works
When we get to you, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to several days, depending on the number of plots. For a village or hamlet like Winkfield Street, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We go through the snagging list or plot schedule and agree the joints to do.
- The old bead comes out in full, with no layer left behind.
- We clean off dust from the build and prime the surfaces where the product needs it.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
How to prepare
- Clear items away from the joints we are working on
- Keep children and pets away from the work area
- Mention any parking rules near the property

Advice
Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. It won’t solve:
- Leaking fittings rather than failed sealant
- A tray or bath that is not properly supported, until it’s fixed
- Disputes or warranty claims with your builder
Not sure which it is? You can ring 0345 464 0079 or send us an email and we will tell you honestly before booking.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Photograph failed sealant before it’s redone
- Use the extractor fan every time you shower
- Avoid scourers and strong chemicals on sealant
- Wait for the cure time before using a resealed shower
Don’t stand on the bath edge or the lip of the tray while the sealant cures. Report any movement in a bath or tray.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
