New build mastic in Kennington, done properly
Snagging sealant properly means taking the failed bead out completely. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you’re dealing with joints pulling apart as timber shrinks and second-fix sealing on new plots, we can put it right, on bathrooms & en suites, kitchens and skirting & floors alike.
In smaller places like Kennington, new homes tend to come as small developments or single plots. Each still needs its sealant and floor joints finished properly from day one.
All our work comes with our 12-month guarantee, wherever you are in Oxfordshire.

What the job involves on each surface
Kitchens
Worktop, upstand and sink joints in new kitchens often get a hurried bead. We remove it and reseal with a kitchen-suitable sealant.
Plot handovers
We work through plots to your schedule, sealing each room ready for handover. Joints are prepared properly before sealing so the sealant lasts.

Questions from Kennington
Is Kennington in your area for new build mastic?
Yes. We work across London and the South East, and Kennington is part of that. You can call 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Do you work for landlords with property near Radley station?
Yes. We work for landlords and letting agents as well as homeowners. You can phone 0345 464 0079 or email us with the details for a clear quote.
Can you quote for more than one area?
Of course. Doing several areas at once is normally more efficient.
Do you take on second-fix sealing for builders?
Yes. Second-fix sealing in bathrooms, kitchens, frames and floors is part of what we do. We clean and prime joints properly to keep callbacks down.
Will you just run a new bead over the existing one?
No. Sealing over old sealant looks fine for a few weeks, then lifts. All the old sealant comes out before we start.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.

Signs you need new build mastic in Kennington
Baths and trays settle under load once the home is lived in. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used.
Look out for these signs:
- New-build shower sealant that has already split
- Untidy sealant flagged on a snagging list
- Sealant applied over dusty or wet surfaces
- Joints pulling apart as timber shrinks
For new homes near Radley station, it’s worth checking the sealant early, while snags are still fresh.

What we do, step by step
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. It normally takes a few hours for most snagging lists, longer for a run of plots. For a job in Kennington, we agree the time, the access and parking before the day. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We go through the snagging list or plot schedule and agree the joints to do.
- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.
- A sealant chosen for each area goes in and is tooled smooth.
- We check every joint and tell you how long each needs to cure.
Preparing for the visit
- On commercial sites, let us know about site rules
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before

What else we do in Kennington
Why act early in Kennington
It often makes sense to do all the sealant items on a snagging list together. You get one visit and one clear quote for the lot. Homes in smaller places like Kennington can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
We do not show prices on the website, because the cost depends so much on the job itself. For a quick quote, please phone 0345 464 0079 or email us.
