Why deal with it now?
A hairline gap at a skirting can wait, but a leaking seal cannot. Not sure whether yours can wait? You can email us at info@mrmastic.co.uk with a few pictures and we will tell you. In a place like Hardgate, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.

About our new build mastic in Hardgate
Dust is the enemy of new-build sealant. We clean every joint thoroughly and prime where the surface and product need it, so the new bead bonds properly. We work on skirting & floors, bathrooms & en suites and windows & doors, and common reasons people get in touch are cracked caulk along new skirting and plot mastic for developers ahead of handover.
Around smaller Scottish places like Hardgate, new homes tend to be single plots or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
Every job is covered by a one-year guarantee.

When to call us in Hardgate
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops and cracked sealant shows up.
These are the problems we are asked about most:
- New-build shower sealant that has already split
- Sealant that never bonded to the surface
- Untidy sealant flagged on a snagging list
- Joints pulling apart as timber shrinks
In and around Hardgate, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

How to look after the new joints
A little care helps the new joints last. We recommend:
- Record problems with dated pictures
- Avoid scourers and strong chemicals on sealant
- Check bath and shower seals every few months as the house settles
- Wait for the cure time before using a resealed shower
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
Joints and finishes in Hardgate homes
Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
For jobs in and around Hardgate, choosing the right material for each joint is as important as a tidy finish.
