About our new build mastic in Singleton
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. Typical jobs include plot mastic for developers ahead of handover and gaps opening as the house dries out and settles, across kitchens, skirting & floors and windows & doors.
For a small place like Singleton, the journey and access are planned in advance, and the work itself is the same as on any site.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Leave it or put it right?
Running a new bead over the builder’s sealant might look tidy for a few weeks, but it won’t bond to the old layer. Taking it all out and starting again is the only way to get a lasting seal. Older cottages and farmhouses around Singleton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we will go through it with you.

Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Get a leaking seal dealt with straight away
- Use the extractor fan every time you shower
- Report sealant problems to your builder during the snagging period
- Check bath and shower seals every few months as the house settles
Avoid standing on the rim of the bath or the edge of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
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.
Singleton: your questions answered
Is Singleton within the area you cover?
Yes. Singleton 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.
Do you cover Singleton for new build mastic?
Yes. We work across London and the South East, and Singleton is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
Is there a guarantee?
Yes. All our work carries our 12-month guarantee.
Can I send you my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
Will the old sealant be removed?
Yes. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Will there be a smell?
Possibly a little. It fades as the sealant cures, and ventilation helps.
Will it make a mess?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
What new build mastic looks like in Singleton
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Around Singleton, as everywhere, new build mastic is only as good as the preparation behind it. Whether the job is in Singleton itself or nearby, the right material for each joint matters as much as a neat finish.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for most snagging lists, longer for a run of plots. For a village or hamlet like Singleton, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First we work through your snagging list or plot schedule with you.
- We cut out every bit of the failed or messy sealant.
- Surfaces are cleaned of building dust and primed where needed.
- New sealant suited to each joint is applied and tooled neatly.
- Finally, each room is checked and you are given the cure time.
How to prepare
- Mention any tricky access
- Let us know if you’ve seen damp or leaks
- For indoor joints, keep the area dry beforehand if you can

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

We seal show-home bathrooms, kitchens and frames ready for viewings. We’ll plan around viewing times.
