New build mastic in Banknock, done properly
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so it all comes out before we clean, dry and reseal. We are often asked to deal with smeared, uneven beads picked up at snagging and sealant applied over dusty or wet surfaces, on kitchens, show homes and skirting & floors.
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.
You are covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

What we are called out for in Banknock
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracked sealant shows up.
Any of these means the joints need attention:
- Shower seals failing in the first year or two
- Gaps between new skirting and floors
- Worktop and upstand sealant coming away
- Internal frame sealant that has split
In and around Banknock, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Should I go to my builder first?
Report it to the builder first while you are covered. If it isn’t resolved, we’ll cut it out and reseal it.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
Keeping the joints in good condition
To keep the joints looking good and working properly:
- Clean sealant with mild detergent, not abrasives
- Watch for new gaps as the house dries out
- Do not wait for the house to settle if water is getting through
- Report sealant problems to your builder during the snagging period
Photograph failed sealant before it’s redone and keep the builder’s replies. It’s useful if you need to raise other issues later.
Report failed sealant to the builder while you are in the snagging period. After that, putting it right may fall to you.
Why it’s worth doing now in Banknock
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
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.
