New Build Mastic in Newtimber
Plot mastic for developers and snagging failed sealant in new homes for homes and businesses in Newtimber and across West Sussex. Fully insured, ARBOMaster approved and guaranteed for a year.
- Skirting joints opening in the first winter
- Kitchen sealant that has pulled off the wall
- Joints pulling apart as timber shrinks
Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
New build mastic for homes and businesses in Newtimber
A new house keeps drying out and settling for its first couple of years. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you are dealing with worktop and upstand sealant coming away and cracked sealant around new window and door frames, we can help.
In a village or hamlet like Newtimber, 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 something is not right with it in that time, tell us and we will put it right.

When it isn’t the sealant
Sealant isn’t the answer to every problem, and we will tell you before we start. Sealant will not put right:
- Cracking that points to a structural problem
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
If you’re not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer before booking.

Joints and finishes in Newtimber homes
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.
In and around Newtimber, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. If you’ve bought a new home near Hassocks station, the sealant around baths, showers and frames is worth checking in the first year or two.

What we do, step by step
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for most snagging lists, longer for a run of plots. Somewhere like Newtimber needs a little journey planning: 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.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- 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.
- We tool every joint neatly and tell you when each area can be used.
Preparing for the visit
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
- Tell us about access, such as stairs, a lift or high-level joints

Your questions about new build mastic in Newtimber
Do you cover smaller places like Newtimber?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is Newtimber in your area for new build mastic?
Yes. We work across London and the South East, and Newtimber is part of that. You can phone 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
Is it worth resealing while the house is still settling?
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.
I rent my home. Can I book you?
Yes. Ask your landlord first, and we can send them the quote if that helps.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.
How long should I leave it?
That depends on the sealant used, so follow the cure time we give you.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status.
Will you just run a new bead over the existing one?
No. Fresh silicone doesn’t stick to the old layer, so it soon lifts and traps water. The old sealant always comes out first.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We also work for property managers and facilities teams. Several sites can be quoted together, and we are fully insured for the work.

Why it’s worth doing now in Newtimber
The builder is normally the first port of call while the snagging or warranty period runs. If it’s slow, or the same joint keeps failing, a proper reseal from a specialist is the next step. Where a wall is exposed, as many are in small places like Newtimber, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Combining jobs into one visit is generally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.
