New Build Mastic in Widewall
New-build sealant joints in Widewall need attention? We cut out the old, prepare the joints and apply the right sealant.
- Untidy sealant flagged on a snagging list
- Plot mastic for developers ahead of handover
- Shower seals failing in the first year or two
How we handle new build mastic in Widewall
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you are dealing with leaking shower tray seals in a new home and skirting joints opening in the first winter, we can help.
Timber frame is common in newer Scottish homes, and it settles over the first years, so skirting and floor joints can open up. 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.

Aftercare tips
So the new joints stay in good condition:
- Act quickly if a seal starts to leak
- Check bath and shower seals every few months as the house settles
- Resist patching a failed seal with a tube from the DIY shop
- Put sealant faults on your snagging list early
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
A failed seal in a new home lets water into joists, plasterboard and ceilings. Early resealing keeps the job small and the new finishes intact.
What we do, step by step
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours for most snagging lists, longer for a run of plots in most cases. For a place like Widewall, longer drives are planned in advance. Mention tracks, gates, ferries or anything else about the route.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- The failed sealant is removed completely down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
How to prepare
- Clear items away from the joints we are working on
- Mention any sign-in or site rules at work premises
- Let us know if you’ve seen damp or leaks

Questions from Widewall
What guarantee comes with new build mastic in Widewall?
All our work, in Widewall and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.
Do you cover smaller places like Widewall?
Yes. Widewall is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland, including the islands, where work is planned around ferry crossings. Let us know about access, parking and anything unusual about getting there when you book.
Is it worth trying it myself?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. We can always put it right if it fails.
Why has my new-build shower seal failed already?
Cracking in the first couple of years is common. Rushed application on dusty surfaces makes it worse.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
How do I get a quote for new build mastic in Widewall?
There’s no set price, as it depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
What do you need from me for a quote?
A short description and the location. We’ll ask anything else we need to know.
Can I send you my snagging list?
Yes. Photos of each sealant item help us quote. Items that need a plumber, tiler or the builder are flagged.
Common problems we fix in Widewall
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
People normally contact us when they notice one of these:
- New-build shower sealant that has already split
- Cracked sealant around new window and door frames
- Untidy sealant flagged on a snagging list
- Gaps behind new kitchen upstands
Around Widewall, as everywhere, new build mastic is only as good as the preparation behind it.

Joints and finishes in Widewall homes
Widewall 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.
Whether the job is in Widewall itself or nearby, the right material for each joint matters as much as a neat finish.

Should I try it myself first?
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
