Advice
New build mastic in Langley Vale, done properly
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. If you’re still within the builder’s snagging or warranty period, tell them first and if that stalls, we can do it. If you have new-build shower sealant that has already split and internal frame sealant that has split, we can put it right, whatever the surface.
Older homes in small places like Langley Vale often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
You get a one-year guarantee, the same in Langley Vale as everywhere else we work.

Signs you need new build mastic in Langley Vale
Sealant applied onto damp surfaces does not bond well. On a busy site, joints are not always given time to dry before the sealant goes on.
These are the problems we’re asked about most:
- Shower seals failing in the first year or two
- Gaps behind new kitchen upstands
- Smeared, uneven beads picked up at snagging
- Sealant that never bonded to the surface
Around Langley Vale, as everywhere, new build mastic is only as good as the preparation behind it.
Before you book anyone
- Are they insured?
- Is the old sealant removed completely?
- How much experience the applicator has
- Whether you can choose the colour
DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
What the job involves on each surface
Windows and doors
On new builds, external frame sealant can be patchy. We reseal it with a weatherproof, flexible sealant.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We take it out and reseal neatly, colour-matched where it shows.
What new build mastic looks like in Langley Vale
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Leave it or put it right?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Cutting out, cleaning and priming are what make the difference. In a small place like Langley Vale, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first.

Aftercare tips
A little care helps the new joints last. We recommend:
- Watch for new gaps as the house dries out
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
- Use the extractor fan every time you shower
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak in a busy bathroom.
