How we handle new build mastic in Clachan Seil
Snagging sealant properly means taking the failed bead out completely. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. We work on bathrooms & en suites, skirting & floors and windows & doors, and common reasons people get in touch are gaps opening as the house dries out and settles and sealant that never bonded to the surface.
Work in a place like Clachan Seil is planned ahead, journey included. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
All our work is covered by a one-year guarantee, wherever you are in Argyll and Bute.

It normally takes a few hours for most snagging lists, longer for a run of plots.

Advice
When something else is needed
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Damaged fittings that need replacing
- Leaking fittings rather than failed sealant
- Disputes or warranty claims with your builder
If you are not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.

Joints and finishes in Clachan Seil homes
Clachan Seil is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
In and around Clachan Seil, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint. For jobs in and around Clachan Seil, choosing the right material for each joint is as important as a tidy finish.

Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Leave it or put it right?
Water getting past a failed seal in a new build reaches walls and floors that are still settling. Resealing promptly protects the new finishes around it. In a place like Clachan Seil, small leaks are easy to put off, but water behind a failed seal does the most damage when nobody’s watching.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re unsure, send an email to info@mrmastic.co.uk for an honest opinion and a quote.

Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How to look after the new joints
Good habits help new joints last longer. Our tips:
- Open a window or run the fan after bathing
- Watch for new gaps as the house dries out
- Do not wait for the house to settle if water is getting through
- Wipe joints with warm soapy water
Avoid standing on the rim of the bath or the edge of the tray while the sealant cures. Report any movement in a bath or tray.
Don’t let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you so report it promptly.
