New build mastic in East Mersea, done properly
New homes move as they dry out. Timber shrinks, plaster dries and baths and trays bed down, so sealant that was laid quickly before handover often cracks. If you have joints pulling apart as timber shrinks and sealant work across a run of new homes, we can put it right.
Around East Mersea, older homes often have timber floors that move through the year, so skirting and threshold joints need a flexible sealant rather than a rigid filler.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or send us an email.

Are you ARBOMaster approved?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
My new home is still under warranty. Should I contact you?
Start with the builder if you are in the snagging or warranty period. If it isn’t resolved, we can reseal it properly.
When is the best time to reseal in a new build?
That depends on the joint. Failed seals in wet areas need doing now, while small cosmetic gaps can wait a while.
Is there any odour?
Possibly a little. It fades as the sealant cures.
How much does new build mastic cost in East Mersea?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.

What new build mastic looks like in East Mersea
East Mersea is close to the coast. New homes near the sea put their outside mastic to work from day one, 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.
For new homes near Alresford station, it’s worth checking the sealant early, while snags are still fresh.

Surface by surface

We seal show-home bathrooms, kitchens and frames ready for viewings. Tell us when the home is open so we can plan around it.
Plot handovers
Developers can send the plot schedule and specification and we’ll quote. Sealant work across the plot is covered as agreed.
DIY versus a professional finish
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Aftercare tips
Looking after new joints is easy:
- Avoid scourers and strong chemicals on sealant
- Get a leaking seal dealt with straight away
- Keep water off fresh sealant until it has cured
- Watch for new gaps as the house dries out
Don’t stand on the bath edge or the lip of the tray in the first few weeks. Report any movement in a bath or tray.
If a shower tray or bath seal splits in the first year, look for movement. Have it resealed, and the tray or bath checked, before it gets worse.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but a leaking seal can’t. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few pictures. In a small place like East Mersea, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Advice
Landlord and commercial work in East Mersea
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
