How we handle new build mastic in Allhallows-on-Sea
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over. We work on show homes, kitchens and plot handovers, and the jobs we see most are worktop and upstand sealant coming away and internal frame sealant that has split.
For a small place like Allhallows-on-Sea, the journey and access are planned in advance, and once on site, the job is the same as anywhere.
We guarantee the work for a year. If something is not right with it in that time, tell us and we will put it right.

Can I do it myself?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

When something else is needed
New sealant cannot fix everything, and we’d rather say so up front. Sealant will not put right:
- Settlement cracks that need a surveyor
- Movement caused by a poorly fitted tray or bath
- Your warranty claim itself, which is between you and the builder
Not sure which it is? You can call 0345 464 0079 or drop us an email and we’ll tell you honestly.

What affects the cost of new build mastic
The quote reflects the job in front of us. We take into account:
- The type of sealant required
- The old material and how stubborn it is
- How easy the joints are to reach
- The size of the job
What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear price before we start.
Asking for a quote
There’s no need for technical detail. Just tell us:
- Whether it’s a home or a business
- The problem you’ve noticed
- The address or postcode of the job
- Pictures of the joints, sent by email
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. When it suits you, ring 0345 464 0079 or send us an email.
Leave it or put it right?
Small cosmetic gaps can wait for the house to settle, but water getting through can’t. Not sure whether yours can wait? You can phone 0345 464 0079 or email us with a few photos and we’ll tell you. In a small place like Allhallows-on-Sea, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Act quickly if a seal starts to leak
- Look at the sealant regularly in the first couple of years
- Follow the cure time we give you
- Raise failed sealant with the developer while you are covered
Leave the sealant for the cure time we give you before showering or bathing. Most silicones need around a day to cure enough for use.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Left alone, a small crack can become a leak.
What new build mastic looks like in Allhallows-on-Sea
Allhallows-on-Sea 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Chalkwell station, it’s worth checking the sealant early, while snags are still fresh.
