Advice
New build mastic in Lullingstone, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference. Typical jobs include smeared, uneven beads picked up at snagging and leaking shower tray seals in a new home, across windows & doors, plot handovers and bathrooms & en suites.
Work in a small place like Lullingstone just needs the journey and access planning, and once on site, the job is the same as anywhere.
You are covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Do you need new build mastic in Lullingstone?
Sealant applied onto damp surfaces does not bond well. Site programmes do not always leave time for joints to dry before the sealant goes on.
If you can see any of these, it’s time to have the joints looked at:
- Sealant work across a run of new homes
- Internal frame sealant that has split
- Kitchen sealant that has pulled off the wall
- Gaps opening as the house dries out and settles
For new homes near Eynsford station, it’s worth checking the sealant early, while snags are still fresh.

Keeping the joints in good condition
So the new joints stay in good condition:
- Open a window or run the fan after bathing
- Avoid running a DIY bead over the old one
- Avoid scourers and strong chemicals on sealant
- Get a leaking seal dealt with straight away
Avoid standing on the rim of the bath or the edge of the tray. If a bath or tray moves when you stand in it, get it looked at.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
What the job involves on each surface
Show homes
In a show home, the sealant is on display. Every bead is neat and coloured to suit the room.
Skirting and floors
Wet-area floor joints need a flexible seal. They get a flexible, water-resistant sealant.
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Settlement cracks that need a surveyor
- Disputes or warranty claims with your builder
- Leaking fittings rather than failed sealant
If in doubt, call 0345 464 0079 or send us an email and we will say what we think.
