- Skirting joints opening in the first winter
What happens on the day
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the work takes a few hours for most snagging lists, longer for a run of plots for a typical job. For a village or hamlet like West Dean, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- The finished joints are checked and the cure times given.
Getting ready for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us if parking is tricky
- Tell us about any previous sealing or DIY attempts

New build mastic in West Dean
We work in new homes and on new-build sites across West Dean. One shower or a whole phase of plots, the method does not change: cut out, clean, prime where needed and reseal neatly. If you have cracked caulk along new skirting and kitchen sealant that has pulled off the wall, we can help, whatever the surface.
Somewhere as small as West Dean, 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.
Every job is covered by a one-year guarantee, wherever you are in West Sussex.

What sealant work can’t fix
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
- Broken tiles or a split tray
If in doubt, ring 0345 464 0079 or send us an email and we’ll say what we think.

Leave it or put it right?
A failed shower or bath seal in a new home lets water into floors and walls that are still drying out. Dealing with it early keeps the damage away from ceilings, floors and finishes. Around West Dean, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
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, then guaranteed for a year.
What else we do in West Dean
Keeping the joints in good condition
So the new joints stay in good condition:
- Wipe joints with warm soapy water
- Act quickly if a seal starts to leak
- Watch for new gaps as the house dries out
- Photograph failed sealant before it’s redone
Do not stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Early resealing keeps the job small and the new finishes intact.
What the job involves on each surface
Bathrooms and en suites
En suite showers are a common source of leaks into the room below. Resealing properly keeps water where it belongs.
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
What new build mastic looks like in West Dean
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
