About our new build mastic in Brantham
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. Both get the same care over preparation since hurried prep is behind a lot of new-build failures. If you’re dealing with leaking shower tray seals in a new home and gaps behind new kitchen upstands, we can put it right, whatever the surface.
Somewhere as small as Brantham, new homes tend to be conversions, self-builds or a few houses rather than an estate. Every one needs its sealant and floor joints done properly, whatever the size of the site.
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.

What happens if it’s left?
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 for the lot. Older cottages and farmhouses around Brantham can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We cut it out and start again.
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.
Common questions in Brantham
Do you cover smaller places like Brantham?
Yes. Brantham is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do new build mastic in Brantham?
Yes. We work across London and the South East, and Brantham is part of that. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Can new sealant go on top of the old bead?
No. Fresh silicone does not stick to the old layer, so sealing over the top fails quickly. The old sealant always comes out first.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you work for landlords and businesses?
Yes, often. We can quote for several properties at once.
What sealant do you use?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we’re using and why.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can you quote for more than one area?
Yes. Just list everything you need and you’ll get one quote.
Keeping the joints in good condition
Aftercare is simple:
- Watch for new gaps as the house dries out
- Open a window or run the fan after bathing
- Get a leaking seal dealt with right away
- Put sealant faults on your snagging list early
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.
How the job changes by surface
Show homes
We can refresh show-home sealant that has discoloured or been knocked. The old bead comes out and a clean new one goes in.
Kitchens
New-kitchen sealant is often applied in a rush. We remove it and reseal with a kitchen-suitable sealant.
Honest limits
To be straight with you, there are a few things sealant will not fix:
- Movement caused by a poorly fitted tray or bath
- Damaged fittings that need replacing
- Settlement cracks that need a surveyor
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before you book.

How the visit works
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. All told, the work takes anything from a few hours to several days, depending on the number of plots. In a small place like Brantham, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we work through your snagging list or plot schedule with you.
- Failed or untidy sealant is cut out completely.
- Surfaces are cleaned of building dust and primed where needed.
- A sealant chosen for each area goes in and is tooled smooth.
- Finally, each room is checked and you are given the cure time.
How to prepare

- Mention any tricky access
- Tell us if parking is tricky

What else we do in Brantham
New build mastic in Brantham: local notes
Brantham is close to 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. 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 Manningtree station, it’s worth checking the sealant early, while snags are still fresh. Around Brantham, as everywhere, new build mastic is only as good as the preparation behind it.
