How we handle new build mastic in Ravenstruther
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly instead of bonding to the dust. We work on windows & doors, kitchens and plot handovers, and the jobs we see most are kitchen sealant that has pulled off the wall and cracked caulk along new skirting.
Timber frame is common in newer Scottish homes, and it settles over the first years, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
A one-year guarantee comes with the work, just as it does everywhere we cover.

Signs you need new build mastic in Ravenstruther
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
The most common problems we see are:
- Cracked sealant around new window and door frames
- Smeared, uneven beads picked up at snagging
- Beads laid onto grit and dust from the build
- New-build shower sealant that has already split
If you’ve bought a new home near Carstairs station, the sealant around baths, showers and frames is worth checking in the first year or two.

Leave it or put it right?
A tube of sealant from the DIY shop will not fix the cause: grit, unprimed surfaces and old layers underneath. Proper removal and preparation are what make it last. Out of town in Scotland, exposed walls take a lot of weather, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Some things make a job bigger or smaller: 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.

Should I try it myself first?
If you’re 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 fails, we can still redo it.
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.
What new build mastic looks like in Ravenstruther
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.

FAQs for Ravenstruther
Is Ravenstruther in your area for new build mastic?

Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Is it normal for sealant to crack in a new home?
A new house dries and settles for a year or two, and sealant is often rushed onto dusty, unprimed surfaces. Either can make it fail early.
Do you have insurance?
Yes, we’re fully insured for domestic and commercial work.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint.
My new home is still under warranty. Should I contact you?
Your builder, if you’re still in their snagging or warranty period. After that, or if their repair keeps failing, we can do it.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Check bath and shower seals every few months as the house settles
- Resist patching a failed seal with a tube from the DIY shop
- Wipe joints with warm soapy water
- Ventilate bathrooms well, especially in the first year
Do not stand on the bath edge or the lip of the tray in the first few weeks. If a bath or tray moves when you stand in it, get it looked at.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
What happens on the day
At the end, we look at the finished work together. The work normally takes a few hours in a single home, depending on the size of the job. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
