Do you need new build mastic in Moredun?
When the heating goes on in the first winter, the house dries fast. Skirting, frames and worktops pull away slightly and cracks appear in the sealant.
Most people get in touch when they notice one of these:
- Beads laid onto grit and dust from the build
- Kitchen sealant that has pulled off the wall
- Leaking shower tray seals in a new home
- Joints pulling apart as timber shrinks
In and around Moredun, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

New build mastic in Moredun
A new build should have a neat, sound bead at every joint. Smeared, patchy or cracked sealant is worth sorting early, before water reaches anything behind it. We’re often asked to deal with messy sealant that spoils new finishes and sealant applied over dusty or wet surfaces, on windows & doors, plot handovers and bathrooms & en suites.
Scotland’s cities are still adding new flats and houses, and new-home owners often find sealant snags in the first year or two.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

If you manage several properties in or around Moredun, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
New build mastic in Moredun: local notes
Moredun is close to the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, and as the frame dries and settles, skirting and sealant joints can open up.
If you’ve bought a new home near Shawfair station, the sealant around baths, showers and frames is worth checking in the first year or two.

Different surfaces, different methods
Kitchens
Beside the sink, the joint takes water every day. We use a sealant suited to kitchens, food-safe where it’s needed.
Plot handovers
Good preparation at handover saves snagging later. We clean out building dust before sealing.
What we can’t put right
It helps to know what we can’t do:
- Broken tiles or a split tray
- A tray or bath that isn’t properly supported, until it’s fixed
- Plumbing faults behind the sealant
If in doubt, send an email to info@mrmastic.co.uk and we will say what we think before booking.
