Thanington New Build Mastic
We cover Thanington for plot mastic for developers and snagging failed sealant in new homes. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Cracked caulk along new skirting
- Frame joints opening as the plaster dries
- Smeared, uneven beads picked up at snagging
New build mastic in Thanington, done properly
Developers send us the plot schedule and we work through it. We seal bathrooms, kitchens, windows, doors and skirting so plots are ready to hand over using the right product for each joint. We work on bathrooms & en suites, skirting & floors and kitchens, and people most often call us about untidy sealant flagged on a snagging list and skirting joints opening in the first winter.
For a new home in or near Thanington, it’s worth checking the sealant early. Common snags include open skirting joints, lifting shower seals and gaps around frames.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

When something else is needed
We’ll always be straight with you, so here’s what sealant cannot fix:
- Cracking that points to a structural problem
- Leaking fittings rather than failed sealant
- Broken tiles or a split tray
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
Joints and surfaces we work on
- Bathrooms & en suites
- Windows & doors
- Show homes
- Skirting & floors
- Plot handovers
- Kitchens
Different surfaces, different methods
Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one.
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. The old sealant comes out and anti-fungal sanitary silicone goes in after cleaning and priming.
How the visit works
You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes anything from a few hours to several days, depending on the number of plots in most cases. For a job in Thanington, we agree the time, the access and parking before the day. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out.
- We clean out the dust and grit left from the build.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Mention any tricky access

Related advice
Why it’s worth doing now in Thanington
A quick bead over the top of the old sealant can look fine at first, but it won’t bond to the old layer. A lasting seal starts with removing the old one completely. Homes in smaller places like Thanington 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.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and give you a clear price before any work starts.
Why choose Mr Mastic in Thanington
- Any old sealant cut out fully, not covered over
- Over 20 years’ experience
- Experience in homes, commercial sites and hotels
- White, clear, grey or coloured to suit, where the product allows

Signs you need new build mastic in Thanington
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 and the sealant may split.
The problems people generally mention when they call are:
- Joints pulling apart as timber shrinks
- Cracked caulk along new skirting
- Sealant applied over dusty or wet surfaces
- Sealant work across a run of new homes
For new homes near Canterbury East station, it’s worth checking the sealant early, while snags are still fresh.
Before booking anyone
- Is the old sealant removed completely?
- Are they insured?
- Whether the sealant suits the joint
- How the colour is chosen
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
