New-build mastic & snagging in Newington, Kent
Our applicators work in Newington on plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Kitchen sealant that has pulled off the wall
- Internal frame sealant that has split
- Skirting joints opening in the first winter
Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Wait for the cure time before using a resealed shower
- Get a leaking seal dealt with right away
- Resist patching a failed seal with a tube from the DIY shop
- Raise failed sealant with the developer while you’re covered
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture doesn’t sit on the sealant.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
New build mastic in Newington, done properly
Snagging sealant properly means taking the failed bead out completely. Fresh silicone cannot bond to the old layer, so it all comes out before we clean, dry and reseal. If you have internal frame sealant that has split and gaps between new skirting and floors, we can help.
Somewhere as small as Newington, new homes tend to be conversions, self-builds or a few houses rather than an estate. Each still needs its sealant and floor joints finished properly.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

What new build mastic looks like in Newington
Newington 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.
Around Newington, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Folkestone West station, it’s worth checking the sealant early, while snags are still fresh.

Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. Older cottages and farmhouses around Newington can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Related advice
Different surfaces, different methods
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. A fresh flexible bead closes them.
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
What affects the quote in Newington
We do not publish a price list. The quote depends on:
- The size of the job
- The old material and how stubborn it is
- Whether the work is at height
- Any mould that needs treating
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
What to tell us for a quote
To make quoting easier, let us know:
- What’s wrong with the joints now
- Any previous sealing or DIY work
- The type of property
- How many joints, rooms or windows are involved
