New build mastic in Haggs
We never seal over a failed new-build bead. New silicone won’t bond to old silicone, so the joint is cut out, cleaned, dried and resealed. If you have sealant applied over dusty or wet surfaces and internal frame sealant that has split, we can put it right, on kitchens, show homes and bathrooms & en suites alike.
Many newer homes in Scotland are timber-framed and settle as they dry out, so skirting and floor joints can open up. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
Big or small, it’s backed by our one-year guarantee.

Different surfaces, different methods
Skirting and floors

Windows and doors
The gap between a new frame and its plaster reveal often opens up. We remove cracked sealant and apply a flexible one in a matching colour.
What new build mastic looks like in Haggs
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Around Haggs, as everywhere, new build mastic is only as good as the preparation behind it. If you’ve bought a new home near Cumbernauld station, the sealant around baths, showers and frames is worth checking in the first year or two.

How we quote for new build mastic
Call for a quick quote. The main things that affect it are:
- Access and height
- Any working-time requirements on site
- Mould in or behind the old joints
- How much old sealant there is and how hard it is to remove
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Helping us quote
When you contact us, it’s useful to know:
- Roughly how big the job is
- Whether it’s a home or a business
- Where the property is
- Photos by email, if that’s easy
It all starts with a short chat. Describe the problem, the location and the size of the job, and we will explain how we’d tackle it. Whenever you’re ready, drop us a line at info@mrmastic.co.uk.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. Not sure whether yours can wait? You can email us at info@mrmastic.co.uk with a few pictures. 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.
Rather than a set price list, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Watch for new gaps as the house dries out
- Don’t seal over failed sealant yourself
- Open a window or run the fan after bathing
- Act quickly if a seal starts to leak
Keep the bathroom ventilated, especially in the first year. Run the fan or open a window after bathing.
Don’t let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.
DIY sealant or a professional job?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
