For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. Typical jobs include sealant that never bonded to the surface and skirting joints opening in the first winter, on plot handovers, windows & doors and show homes.
If you’ve bought a new home in or near East Wittering, the first year or two is a good time to check the sealant. Common snags include open skirting joints, lifting shower seals and gaps around frames.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. A few tips:
- Wipe joints with warm soapy water
- Check bath and shower seals every few months as the house settles
- Use the extractor fan every time you shower
- Follow the cure time we give you
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
A seal that splits early is often a sign of movement. Getting it resealed properly, and any movement checked, stops it recurring.
Why it’s worth doing now in East Wittering
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. In an older home around East Wittering, damp from a failed joint can get into timber and plaster, which is far harder to put right than the sealant itself.

New build mastic in East Wittering: local notes
East Wittering is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Whether the job is in East Wittering itself or nearby, the right material for each joint matters as much as a neat finish.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Signs you need new build mastic in East Wittering
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
The most common problems we see are:
- Internal frame sealant that has split
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
- Kitchen sealant that has pulled off the wall
In and around East Wittering, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
