What the job involves on each surface
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.

Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
New homes and floors in Upper Dicker
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In and around Upper Dicker, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

When to call us in Upper Dicker
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. Drying timber shrinks and pulls joints apart and the sealant has to cope with the movement.
The problems people usually mention when they call are:
- Gaps between new skirting and floors
- Messy sealant that spoils new finishes
- Worktop and upstand sealant coming away
- Shower seals failing in the first year or two
For new homes near Berwick (Sussex) station, it’s worth checking the sealant early, while snags are still fresh.

Why it’s worth doing now in Upper Dicker
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Older cottages and farmhouses around Upper Dicker can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Report sealant problems to your builder during the snagging period
- Act quickly if a seal starts to leak
- Keep photos and emails about snagging items
- Open a window or run the fan after bathing
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
