About our new build mastic in Church Norton
Across Church Norton, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: cut out, clean, prime where needed and reseal neatly. We are often asked to deal with frame joints opening as the plaster dries and new-build shower sealant that has already split, across bathrooms & en suites, kitchens and plot handovers.
In a village or hamlet like Church Norton, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Big or small, it’s backed by our one-year guarantee.

Landlord and commercial work in Church Norton
If you manage several properties in or around Church Norton, several properties can be quoted together. Just tell us the addresses and what each one needs.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
What happens if it’s left?
A tube of sealant from the DIY shop won’t fix the cause: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Where a wall is exposed, as many are in small places like Church Norton, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask a few questions first and give you a clear price before work begins.
Why book with us
- Anti-fungal sanitary silicone in wet areas
- Any old sealant cut out fully, not covered over
- Trusted Arbo and Everbuild sealants
- A choice of colours where the product allows

When to call us in Church Norton
Not every new-build joint gets the right sealant: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
If you can see any of these, it’s time to have the joints looked at:
- Second-fix sealing on new plots
- Leaking shower tray seals in a new home
- Gaps between new skirting and floors
- Frame joints opening as the plaster dries
Around Church Norton, as everywhere, new build mastic is only as good as the preparation behind it.
What to look for in a quote
- How the joint is cleaned and prepared
- Are they insured?
- What the cure time is
- Whether the sealant suits the joint
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep photos and emails about snagging items
- Ventilate bathrooms well, especially in the first year
- Raise failed sealant with the developer while you are covered
- Keep water off fresh sealant until it has cured
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing to help keep mould away.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you so report it promptly.
Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

How the visit works
You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes anything from a few hours to several days, depending on the number of plots for a typical job. In a small place like Church Norton, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children
- For indoor joints, keep the area dry beforehand if you can

New build mastic around Church Norton
Church Norton is within about 1 mile of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. 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.
For new homes near Bognor Regis station, it’s worth checking the sealant early, while snags are still fresh.
