Plot mastic for developers and snagging failed sealant in new homes in Newbridge, with a 12-month guarantee on every job. Call for a quick quote.
- Sealant applied over dusty or wet surfaces
- Plot mastic for developers ahead of handover
- Leaking shower tray seals in a new home
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Keep water off fresh sealant until it has cured
- Act quickly if a seal starts to leak
- Report sealant problems to your builder during the snagging period
- Wipe joints with warm soapy water
Watch the joints as the house settles. Hairline gaps can open as timber and plaster dry.
Lifting sealant traps moisture and mould behind it. Resealing before mould gets in keeps the job straightforward.
New build mastic for homes and businesses in Newbridge
If your new home has a leaking shower seal, open skirting joints or untidy sealant, we can help. While the builder’s snagging or warranty period runs, report it to them first, and if it is not put right, get in touch with us. We work on plot handovers, windows & doors and show homes, and the jobs we see most are skirting joints opening in the first winter and frame joints opening as the plaster dries.
In a village or hamlet like Newbridge, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the visit works
Every visit runs the same way: we check the joints, protect the area around them, do the work and clear up. It usually takes a few hours in a single home. For a village or hamlet like Newbridge, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- For indoor joints, keep the area dry beforehand if you can
- Tell us if parking is tricky
- Move anything stored near the joints

Why deal with it now?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. It’s one visit, one quote and one set of cure times. Around Newbridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
What you get with us
- Neat joints and a tidy finish
- Experience in homes, commercial sites and hotels
- Quality sealants from Arbo and Everbuild
- We agree the colour with you first

Surface by surface
Kitchens
Sink joints are wet all the time. A kitchen sealant goes in there suited to the job.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Each joint is cleaned and primed where needed so the sealant lasts.
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Deciding who is responsible under a builder’s warranty
- Damaged fittings that need replacing
- Settlement cracks that need a surveyor
Not sure which it is? You can call 0345 464 0079 or send us an email and we will tell you honestly before booking.
Surfaces we seal
- Show homes
- Plot handovers
- Kitchens
- Bathrooms & en suites

Your questions about new build mastic in Newbridge
Can you do new build mastic in Newbridge?
Yes, Newbridge is within the area we cover. Our work covers London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will give you a clear quote.
Do you cover smaller places like Newbridge?
Yes, Newbridge is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I go to my builder first?
If you are still within the builder’s snagging or warranty period, report it to them first. If they’re slow or the fix does not last, we can help.
Do you work for letting agents?
Yes, regularly. We can quote for several properties at once, and between tenancies is a good time for the work.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme. Tell us the plots and the joints involved for a clear quote.
Do you use white or clear sealant?
The colour is chosen to suit the tiles, worktop or frame. Let us know your preference when you ask for a quote.
Should I wait before resealing?
For failed seals that let water through, the best time is now. Cosmetic gaps can wait until the first year or two of movement has passed.
Can new sealant go on top of the old bead?
No. New silicone won’t bond to old silicone, so it soon lifts and traps water. We cut the old bead out completely.
Signs you need new build mastic in Newbridge
If plaster or screed was still damp when it was sealed, the bond suffers. On a busy site, joints are not always given time to dry.
The problems people normally mention when they call are:
- Beads laid onto grit and dust from the build
- Gaps behind new kitchen upstands
- Sealant work across a run of new homes
- Cracked caulk along new skirting
For new homes near Ashurst New Forest station, it’s worth checking the sealant early, while snags are still fresh.
