New build mastic in Slamannan, done properly
Across Slamannan, we work for both new-home owners and the builders handing those homes over. Whether it’s one en suite or a run of plots, the method is the same: remove, clean, prime where needed, then a neat new bead. If you have messy sealant that spoils new finishes and sealant that never bonded to the surface, we can help, on skirting & floors, bathrooms & en suites and show homes 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.
All our work comes with a one-year guarantee.

Should I try it myself first?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, 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.

Keeping the joints in good condition
To keep the joints looking good and working properly:
- Keep pictures and emails about snagging items
- Resist patching a failed seal with a tube from the DIY shop
- Get a leaking seal dealt with right away
- Wait for the cure time before using a resealed shower
Keep an eye on the joints over the first couple of years. Small gaps can appear as the house dries and can be resealed later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you.
Common problems we fix in Slamannan
Once people move in, baths and trays take weight and bed down. A bath sealed empty drops slightly when filled, straining the joint and can tear.
Signs it’s time to call us include:
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
- Gaps between new skirting and floors
- Beads laid onto grit and dust from the build
For new homes near Caldercruix station, it’s worth checking the sealant early, while snags are still fresh.

Why act early in Slamannan
For developers, getting the sealant right first time saves return visits. Every return visit for a failed seal takes time. 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.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

How the visit works
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours in a single home. Outside jobs in Slamannan need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.
- We look at why each joint failed, including any movement.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- New sealant goes in, with baths filled first so they’re at their heaviest.
- We check every joint and leave you with the cure times.
Before we arrive
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints
- For indoor joints, keep the area dry beforehand if you can
