What we’re called out for in Whitemans Green
Once people move in, baths and trays take weight and bed down. If a bath wasn’t filled when it was sealed, the bead is stretched the first time it’s used and can tear.
Common reasons people contact us are:
- Skirting joints opening in the first winter
- Beads laid onto grit and dust from the build
- Plot mastic for developers ahead of handover
- Smeared, uneven beads picked up at snagging
In and around Whitemans Green, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic in Whitemans Green, done properly
We carry out plot mastic and second-fix sealing for builders, and snagging reseals for new-home owners. In both, preparation makes the difference, because that is what rushed new-build sealant normally lacks. We work on kitchens, plot handovers and bathrooms & en suites, and the jobs we see most are sealant applied over dusty or wet surfaces and frame joints opening as the plaster dries.
For a small place like Whitemans Green, the journey and access are planned in advance, and the work itself is the same as on any site.
There’s a 12-month guarantee on every job, large or small.

What else we do in Whitemans Green
What happens if it’s left?
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can call 0345 464 0079 or drop us an email with a few pictures. Older cottages and farmhouses around Whitemans Green can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Look at the sealant regularly in the first couple of years
- Don’t wait for the house to settle if water is getting through
- Avoid running a DIY bead over the old one
- Photograph failed sealant before it’s redone
Keep pictures of the joints and any snagging correspondence with your builder. It helps if anything else comes up during the warranty period.
Early snagging is easier snagging. Small faults turn into leaks if left.
How the job changes by surface
Bathrooms and en suites
Baths, showers, basins and trays in new bathrooms are the most common new-build reseal. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens, food-safe where it’s needed.
