About our new build mastic in Wouldham
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. We work on show homes, skirting & floors and kitchens, and common reasons people get in touch are kitchen sealant that has pulled off the wall and sealant work across a run of new homes.
Older homes in small places like Wouldham often have timber floors that move with the seasons, which is why skirting and threshold joints need a flexible sealant, not filler.
Each job carries a 12-month guarantee, large or small.

Signs you need new build mastic in Wouldham
New homes are full of moisture from plaster, screed and concrete, which takes a year or two to dry out. As it does, timber shrinks and joints open, and sealant that cannot keep up splits.
Most people get in touch when they notice one of these:
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
If you’ve bought a new home near Halling station, the sealant around baths, showers and frames is worth checking in the first year or two.

- Which colour the sealant will be

Surface by surface
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. The joint is stripped back before the new bead goes in.
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.

Other services in Wouldham
Leave it or put it right?
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Around Wouldham, older homes often have timber in their 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 are unsure, phone 0345 464 0079 or email us and we’ll give you an honest view and a quote.

Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Raise failed sealant with the developer while you’re covered
- Keep photos and emails about snagging items
- Act quickly if a seal starts to leak
- Wait for the cure time before using a resealed shower
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers to help keep mould away.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.

How it works
Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the number of plots. In a small place like Wouldham, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

- We remove the failed sealant and clean the joints.
- 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.
Before we arrive
- Tell us about any water getting in
- Try not to wet indoor joints just before the visit
