About our new build mastic in Carbrain
Building dust is behind a lot of failed 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 messy sealant that spoils new finishes and frame joints opening as the plaster dries, we can help.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Ventilate bathrooms well, especially in the first year
- Record problems with dated photos
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
Keep an eye on the joints over the first couple of years. Hairline gaps can open as timber and plaster dry, and they’re simple to reseal once movement has slowed.
Mould takes hold quickly in sealant that has gaps or lifted edges. Dealing with it before it goes black keeps the job straightforward.

Related advice
Different surfaces, different methods
Bathrooms and en suites
Trays and baths in new builds settle as they’re used. We reseal once the old bead is fully out with baths filled first.
Windows and doors
A draught at a new window can be a missed or failed joint. We check and reseal the frame edges.
What we are called out for in Carbrain
Baths and trays settle under load once the home is lived in. A bath sealed empty drops slightly when filled, straining the joint and can tear.
The problems people usually mention when they call include:
- Leaking shower tray seals in a new home
- Messy sealant that spoils new finishes
- Gaps behind new kitchen upstands
- Beads laid onto grit and dust from the build
Around Carbrain, as everywhere, new build mastic is only as good as the preparation behind it.

Your questions about new build mastic in Carbrain
Is Carbrain in your area for new build mastic?
Yes, Carbrain is within the area we cover. We work across all of Scotland. You can send an email to info@mrmastic.co.uk and tell us what needs doing.
I let a flat near Cumbernauld station. Can you help?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just drop us a line at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
Should I go to my builder first?
While the snagging or warranty period runs, the builder should be your first contact. If they’re slow or the fix doesn’t last, we can help.
Will the old sealant be removed?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Can I send you my snagging list?
Yes. Send it with pictures and we’ll quote for the sealant items. If something isn’t sealant, we’ll say so.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can new sealant go on top of the old bead?
No. We always remove the existing bead, then clean and prime the joint, before resealing.
What does new build mastic cost?
There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.

Can I do it myself?
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.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Joints and finishes in Carbrain homes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
