Advice
About our new build mastic in Deanston
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. Typical jobs include smeared, uneven beads picked up at snagging and kitchen sealant that has pulled off the wall, on plot handovers, windows & doors and bathrooms & en suites.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. In older homes, timber floors move through the year too.
Big or small, you get the same one-year guarantee.

What we can’t put right
New sealant can’t fix everything, and we’d rather say so up front. Sealant will not put right:
- Your warranty claim itself, which is between you and the builder
- Movement caused by a poorly fitted tray or bath
- Leaks from pipes, valves or wastes, which need a plumber
Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly.

Leave it or put it right?
Sealant done properly at handover means fewer callbacks. Snagging visits for failed sealant cost time on every plot and most come down to preparation. Around Deanston, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

New build mastic in Deanston: local notes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles. Deanston 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.
Around Deanston, as everywhere, new build mastic is only as good as the preparation behind it.

Other services in Deanston
Do you need new build mastic in Deanston?
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and the sealant may split.
People normally contact us after spotting one of these:
- New-build shower sealant that has already split
- Smeared, uneven beads picked up at snagging
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
For new homes near Dunblane station, it’s worth checking the sealant early, while snags are still fresh.
What to look for in a quote
- What happens if they find a problem under the old sealant
- What the cure time is
- Whether all the old sealant comes out first
- The length of the guarantee
Looking after it afterwards
Joint life depends on how it’s used and looked after. We suggest:
- Keep water off fresh sealant until it has cured
- Clean sealant with mild detergent, not abrasives
- Open a window or run the fan after bathing
- Photograph failed sealant before it’s redone
Follow the cure time we give you before the area gets wet. Silicone is generally left for about a day.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black saves a harder job later.
Deanston: your questions answered
Is Deanston within the area you cover?
Yes, smaller places are covered as well as towns. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Dunblane station?
Yes, we work for letting agents and landlords. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will send you a clear quote.
Is it worth trying it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Are you fully insured?
Yes. We’re fully insured, and we can confirm the details when we quote.
Is there a guarantee?
Yes. There’s a 12-month guarantee on every job, wherever you are.
When is the best time to reseal in a new build?
It depends on whether water is getting through. A leaking shower or bath seal should be redone right away, but cosmetic gaps can wait for movement to slow.
Do the sealants smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long does the job take?

Different surfaces, different methods
Bathrooms and en suites
En suite seals are easy to miss on a snagging list until they leak. A proper reseal keeps water in the tray.
Windows and doors
Draughts around new frames are often a sealant gap. We check and reseal the frame edges.
