How we handle new build mastic in West Wittering
Some new-home owners let the house settle before resealing. That makes sense for small gaps that are just cosmetic, but a failed shower or bath seal shouldn’t wait. Typical jobs include gaps opening as the house dries out and settles and sealant applied over dusty or wet surfaces, across bathrooms & en suites, show homes and windows & doors.
Around West Wittering, older homes often have timber floors that move through the year, which is why skirting and threshold joints need a flexible sealant, not filler.
All of our work is guaranteed for twelve months, in West Wittering and everywhere else we cover.

Leave it or put it right?
A tube of sealant from the DIY shop won’t fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Older cottages and farmhouses around West Wittering can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

New build mastic in West Wittering: local notes

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Around West Wittering, as everywhere, new build mastic is only as good as the preparation behind it.

When is the best time to reseal in a new build?

How long should I leave it?
It depends on the product. We tell you how long to leave it before we go.
Are you fully insured?

Why does sealant fail so quickly in new builds?
A new house dries and settles for a year or two, and sealant is often applied quickly onto dusty surfaces. Either can make it fail early.

Signs you need new build mastic in West Wittering
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Both fail early.
Keep an eye out for any of the following:
- Untidy sealant flagged on a snagging list
- Cracked caulk along new skirting
- Gaps opening as the house dries out and settles
- Beads laid onto grit and dust from the build
If you’ve bought a new home near Nutbourne station, the sealant around baths, showers and frames is worth checking in the first year or two.

What the job involves on each surface
Skirting and floors
Gaps under skirting are one of the most common new-build snags. A flexible sealant closes it without cracking like caulk.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
How the visit works
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take a few hours for most snagging lists, longer for a run of plots. Somewhere as small as West Wittering, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- We clean out the dust and grit left from the build.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
Before we arrive
- Tell us if parking is tricky
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
