Floor joint sealing in Newmill
The gap under a skirting board often opens as floors and walls move with the seasons. Caulk tends to crack there, so we close it with a flexible sealant instead. We work on commercial floors, skirting boards and concrete floor joints, and common reasons people get in touch are cracked caulk along skirting in bathrooms and kitchens and floor edges that trap water and grime.
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.
There’s a 12-month guarantee on every job, whatever its size.

Aftercare tips
So the new joints stay in good condition:
- Look at floor joints each spring
- Have a cracking tiled floor checked before tiles break
- Keep caulk for dry, still joints only
- Vacuum floor joints regularly to stop grit building up
Silicone sealant is not made to take paint. If the joint will be painted, tell us beforehand so we use a paintable sealant.
In wet areas, an open floor joint lets water reach the subfloor. A sound seal stops that happening.
Honest limits
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Loose, hollow or cracked tiles, which need a tiler
- Subfloor problems that need a flooring contractor
- Failed waterproofing under a wet room floor
If in doubt, send an email to info@mrmastic.co.uk and we’ll say what we think.

Can I do it myself?
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Joints and finishes in Newmill homes
Floors around the Scottish Borders run from suspended timber in older homes to concrete in newer houses and units, and they do not all move the same way. The joint at the skirting or threshold has to allow for that. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
For jobs in and around Newmill, choosing the right material for each joint is as important as a tidy finish. In and around Newmill, as anywhere, good floor joint sealing starts with a clean, dry, properly prepared joint.
