New build mastic in Westbourne, done properly
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, and sealant applied in a hurry at handover can split. Common call-outs are for shower seals failing in the first year or two and beads laid onto grit and dust from the build, across windows & doors, plot handovers and show homes.
Around Westbourne, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
Whatever the size of the job, you get the same one-year guarantee.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance.
Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Aftercare tips
Aftercare is simple:
- Clean sealant with mild detergent, not abrasives
- Look at the sealant regularly in the first couple of years
- Use the extractor fan every time you shower
- Raise failed sealant with the developer while you are covered
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry and can be resealed later.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Structural cracks in walls or ceilings
- Deciding who is responsible under a builder’s warranty
- Cracked trays, tiles or worktops
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before booking.

The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it normally takes a few hours in a single home. For a village or hamlet like Westbourne, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by going through the snagging items or plot schedule with you.
- The failed sealant is removed completely.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints
- Clear the area around the work

Advice
Joints and finishes in Westbourne homes
Westbourne 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you’ve bought a new home near Emsworth station, the sealant around baths, showers and frames is worth checking in the first year or two.
