How we handle new build mastic in Swinhill
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the sealant actually sticks instead of bonding to the dust. If you’re dealing with kitchen sealant that has pulled off the wall and cracked caulk along new skirting, we can put it right, whatever the surface.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. In older homes, timber floors move through the year too.
The work is covered for a year after we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Don’t wait for the house to settle if water is getting through
- Clean sealant with mild detergent, not abrasives
- Watch for new gaps as the house dries out
- Resist patching a failed seal with a tube from the DIY shop
Don’t stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.
What else we do in Swinhill
Different surfaces, different methods
Plot handovers
Plot mastic is carried out to the developer’s schedule. Joints are prepared properly before sealing to keep callbacks down.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Work for landlords, hotels and businesses
For anyone letting property in or around Swinhill, several properties can go on one quote. Send us the addresses and the work at each.
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
Why act early in Swinhill
A quick bead over the top of the old sealant can look fine at first, but it cannot bond to what’s underneath. Taking it all out and starting again is the only way to get a lasting seal. Around Swinhill, water from a failed joint in an older stone home can soak into timber and plaster.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, drop us a line at info@mrmastic.co.uk for an honest opinion and a quote.

DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Do you need new build mastic in Swinhill?
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Keep an eye out for these signs:
- Kitchen sealant that has pulled off the wall
- Beads laid onto grit and dust from the build
- New-build shower sealant that has already split
- Cracks appearing as a new home settles
If you’ve bought a new home near Larkhall station, the sealant around baths, showers and frames is worth checking in the first year or two.
