Different surfaces, different methods

Plot handovers
Developers can send the plot schedule and specification. Sealant work across the plot is covered to the agreed spec.
New build mastic in Stewarton
Some owners wait for the first year’s movement before having joints redone. That makes sense for small gaps that are just cosmetic, but a seal that is letting water through needs doing now. We work on windows & doors, bathrooms & en suites and kitchens, and people most often call us about sealant work across a run of new homes and frame joints opening as the plaster dries.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
All of our work is guaranteed for twelve months, in Stewarton and everywhere else we cover.

Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. In a place like Stewarton, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Why us?
- Over 20 years’ experience
- A choice of colours where the product allows
- We agree the colour with you first
- Tidy, careful work

Signs you need new build mastic in Stewarton
The wrong product is sometimes used in the wrong place: decorators’ caulk in a wet area, or a stiff sealant where there’s movement. Neither lasts long.
Look out for these signs:
- Cracks appearing as a new home settles
- Smeared, uneven beads picked up at snagging
- Kitchen sealant that has pulled off the wall
- Frame joints opening as the plaster dries
In and around Stewarton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

What sealant work can’t fix
In fairness, some problems need a different trade:
- Leaking fittings rather than failed sealant
- Your warranty claim itself, which is between you and the builder
- Baths and trays that move too much for sealant to cope with
If in doubt, drop us a line at info@mrmastic.co.uk and we’ll say what we think before you book.

Questions from Stewarton
Do you work for landlords with property near Stewarton station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just send an email to info@mrmastic.co.uk with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Stewarton?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Where are you based?
We’re a Crawley-based firm, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Do you take on second-fix sealing for builders?
Yes. We seal plots to the developer’s programme ready for handover. Get in touch with the number of plots and the scope for a clear quote.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Do I have to be there?
It depends on the job. Inside work needs someone to give us access, while outside work can sometimes be arranged differently.
New build mastic in Stewarton: local notes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up. Stewarton is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for plot mastic and the sealant in new homes to keep out.
For new homes near Stewarton station, it’s worth checking the sealant early, while snags are still fresh.

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. Most jobs take anything from a few hours to several days, depending on the number of plots.

- 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.
- We tool every joint neatly and tell you when each area can be used.
