How we handle new build mastic in Kingsley
Across Kingsley, 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. If you have new-build shower sealant that has already split and beads laid onto grit and dust from the build, we can put it right, whatever the surface.
For a small place like Kingsley, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
You get a one-year guarantee, the same in Kingsley as everywhere else we work.

Kingsley questions
Is Kingsley within the area you cover?
Yes, Kingsley is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Kingsley in your area for new build mastic?
Yes. We work across London and the South East, and Kingsley is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
When is the best time to reseal in a new build?
For failed seals that let water through, the best time is now. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
Can you do plot mastic on a new development?
Yes. We take on second-fix sealant work across new plots. We clean and prime joints properly to keep callbacks down.
Who should fix failed sealant in a new build?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix does not last, we can help.
Where is Mr Mastic based?
We’re based in Crawley, and we cover South East England, London and all of Scotland.
Do you hold any approvals?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Avoid running a DIY bead over the old one
- Keep water off fresh sealant until it has cured
- Avoid scourers and strong chemicals on sealant
- Get a leaking seal dealt with right away
Clean the sealant with a mild detergent and a soft cloth. Avoid abrasive pads and strong solvents as they wear the bead.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small.
What else we do in Kingsley
Honest limits
New sealant cannot fix everything, and we’ll tell you before any work starts. It won’t solve:
- Your warranty claim itself, which is between you and the builder
- Plumbing faults behind the sealant
- Structural cracks in walls or ceilings
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.

What new build mastic looks like in Kingsley
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you’ve bought a new home near Bentley (Hampshire) station, the sealant around baths, showers and frames is worth checking in the first year or two. In and around Kingsley, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Advice
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.

Surface by surface
Plot handovers
Send us the schedule and any sealant specification for a quote. Sealant work across the plot is covered.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
