New build mastic in Seawick
For builders and developers, we work through plots to the schedule you give us. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. If you have frame joints opening as the plaster dries and new-build shower sealant that has already split, we can help, whatever the surface.
Somewhere as small as Seawick, 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.
Each job carries a 12-month guarantee.

Keeping the joints in good condition
Good habits help new joints last longer. A few tips:
- Watch for new gaps as the house dries out
- Act quickly if a seal starts to leak
- Keep water off fresh sealant until it has cured
- Keep pictures and emails about snagging items
Don’t stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
Early snagging is easier snagging. Left alone, a small crack can become a leak over time.
How we quote for new build mastic
There’s no set price list, because no two jobs are the same. What we look at:
- Whether the work is at height
- Whether there’s mould to deal with
- The old material and how stubborn it is
- The number of rooms or windows
Combining jobs into one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

The process
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for most snagging lists, longer for a run of plots, and the area is left clean. Somewhere like Seawick needs a little journey planning: 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.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- Joints are dried and primed where the product calls for it.
- Baths are filled with water, then the new sealant is applied.
- We check every joint and leave you with the cure times.
How to prepare
- Let us know about earlier repairs to the joints
- Let us know about parking restrictions
- On commercial sites, let us know about site rules

Advice
Why deal with it now?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Dealing with it early keeps the damage away from ceilings, floors and finishes. In a small place like Seawick, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we’ll go through it with you.
Why us?
- Full insurance on every job
- Quality sealants from Arbo and Everbuild
- White, clear, grey or another colour, product permitting
- Old sealant always removed completely
Surface by surface
Bathrooms and en suites
Shower trays in new homes often move slightly in the first year. We reseal once the old bead is fully out.
Skirting and floors
New homes often develop a gap between skirting and floor. We seal it with a flexible sealant that copes with the movement.
For landlords and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

What else we do in Seawick
What new build mastic looks like in Seawick
Seawick is within about 1 mile of 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. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Around Seawick, as everywhere, new build mastic is only as good as the preparation behind it. For new homes near Clacton-On-Sea station, it’s worth checking the sealant early, while snags are still fresh.

Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or drop us an email and let us know what needs doing and where.
Can you reseal over the builder’s sealant?
No. We always remove the existing bead, then clean and prime the joint, and a new bead applied.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common. Poor preparation at handover adds to it.
Can I do it myself?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
