Leave it or put it right?
DIY kits don’t solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Older cottages and farmhouses around Sutton-under-Brailes can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

How we handle new build mastic in Sutton-under-Brailes
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. Both get the same care over preparation, because that is what rushed new-build sealant normally lacks. We work on show homes, skirting & floors and kitchens, and the jobs we see most are sealant work across a run of new homes and frame joints opening as the plaster dries.
Somewhere as small as Sutton-under-Brailes, 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’ll put it right.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Get a leaking seal dealt with straight away
- Record problems with dated pictures
- Wait for the cure time before using a resealed shower
- Watch for new gaps as the house dries out
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
Leave a failed new-build seal and water can reach the floor and the ceiling below. Catching it early keeps the fix to the sealant and protects the rest of the house.
Common problems we fix in Sutton-under-Brailes
Fresh sealant can be knocked or cut by trades finishing off. A bead disturbed before it has cured may never seal properly and it shows once the home is in use.
People generally contact us when they notice something like this:
- Sealant applied over dusty or wet surfaces
- Cracked sealant around new window and door frames
- Leaking shower tray seals in a new home
- Cracks appearing as a new home settles
Around Sutton-under-Brailes, as everywhere, new build mastic is only as good as the preparation behind it.

Sutton-under-Brailes questions
Do you cover Sutton-under-Brailes for new build mastic?
Yes. We work across London and the South East, and Sutton-under-Brailes is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Is new build mastic in Sutton-under-Brailes guaranteed?
All our work, in Sutton-under-Brailes and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
When is the best time to reseal in a new build?
Any seal that is leaking should be redone right away. For small cosmetic gaps, waiting until the house has settled can save doing them twice.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Why does sealant fail so quickly in new builds?
There are generally two causes: movement as the house dries and settles, and sealant laid onto dust without primer. A proper reseal deals with both.
Can landlords and businesses book you?
Yes, often. Several properties can be quoted together.
What should I tell you?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply call 0345 464 0079 or send us an email.
