New build mastic for homes and businesses in Collydean
Our new-build work comes in two parts: plot mastic for developers, and putting right failed sealant for people who’ve bought a new home. In both, preparation makes the difference, because that is what rushed new-build sealant normally lacks. Typical jobs include second-fix sealing on new plots and cracked sealant around new window and door frames, across skirting & floors, bathrooms & en suites and windows & doors.
Many newer homes in Scotland are timber-framed and settle as they dry out, which shows as gaps at skirtings and floor joints. Older stone-built homes, meanwhile, often have timber floors that move with the seasons.
All of our work is guaranteed for twelve months.

DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out 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.
Surface by surface
Kitchens
Sink joints are wet all the time. We use a sealant suited to kitchens suited to the job.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Resist patching a failed seal with a tube from the DIY shop
- Check bath and shower seals every few months as the house settles
- Keep water off fresh sealant until it has cured
- Record problems with dated pictures
Keep the bathroom ventilated, especially in the first year. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
If a shower tray or bath seal splits in the first year, look for movement. Getting it resealed properly, and any movement checked, stops it recurring.

Common problems we fix in Collydean
On many sites, sealant goes on in the final rush before handover. Joints aren’t always cleaned of dust or primed, so the bead never bonds properly.
The problems people generally mention when they call include:
- Gaps behind new kitchen upstands
- Cracked caulk along new skirting
- Untidy sealant flagged on a snagging list
- Shower seals failing in the first year or two
In and around Collydean, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
What your quote should include
- How long the guarantee is
- Are they insured?
- Which colour the sealant will be
- Who turns up on the day
Leave it or put it right?
It often makes sense to do all the sealant items on a snagging list together. It’s one visit, one quote and one set of cure times to plan around. Around Collydean, water from a failed joint in an older stone home can soak into timber and plaster.
