About our new build mastic in Whitecraig
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. We work on bathrooms & en suites, plot handovers and show homes, and people most often call us about worktop and upstand sealant coming away and gaps between new skirting and floors.
New homes in smaller Scottish places are often single plots, self-builds or small developments. They need their sealant and floor joints finished just as carefully as on a big site.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Follow the cure time we give you
- Check bath and shower seals every few months as the house settles
- Clean sealant with mild detergent, not abrasives
- Do not wait for the house to settle if water is getting through
Keep pictures of the joints and any snagging correspondence with your builder. It’s useful if you need to raise other issues later.
Do not let the snagging period run out with sealant problems unreported. Once it ends, the repair may be down to you, so raise it early.

Signs you need new build mastic in Whitecraig
When the heating goes on in the first winter, the house dries fast. Gaps open along skirting, frames and worktops.

- Second-fix sealing on new plots

- Beads laid onto grit and dust from the build
- Skirting joints opening in the first winter
Around Whitecraig, as everywhere, new build mastic is only as good as the preparation behind it.
Questions to ask before booking
- What the cure time is
- Which sealant they’ll use, and why
- Whether all the old sealant comes out first
- What the quote includes, VAT included or not
What we do, step by step
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 anything from a few hours to several days, depending on the number of plots. Outside jobs in Whitecraig need a dry day, because sealant won’t bond to a wet joint, so an outdoor job can move if the forecast changes. Work indoors isn’t affected.
- Each joint is checked for movement before any work starts.
- Old sealant is cut out and the joints cleaned.
- We make sure the joints are dry and prime them if needed.
- Baths are filled with water, then the new sealant is applied.
- The finished joints are checked and the cure times given.
How to prepare
- Mention any tricky access
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules

Joints and finishes in Whitecraig homes
Whitecraig 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. Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
If you’ve bought a new home near Wallyford station, the sealant around baths, showers and frames is worth checking in the first year or two.
Whitecraig is about 2 miles south-east of Musselburgh, in East Lothian. We provide new build mastic to homes and businesses in Whitecraig and the surrounding area. Our East Lothian coverage runs to 48 places, Whitecraig among them. There’s also a page for Edinburgh, about 7 miles away.
All of EH21 is covered for new build mastic. Local streets include Whitecraig Crescent, Whitecraig Terrace and Whitecraig Gardens East, all of which we cover. Other places close to Whitecraig include Carberry (1 mile south-east), Old Craighall (1 mile west), Inveresk (1 mile north), Wallyford (1 mile north-east) and Musselburgh (2 miles north-west).

What’s near Whitecraig
For rail, the closest station is Wallyford station, about 1.6 miles north-east of the centre. A little further out are Musselburgh Doll Museum (1.6 miles north-west) and Midlothian Community Hospital (3.5 miles south-west). Not far away are Whinny Hill and Duddingston Loch.
What happens if it’s left?
A hairline gap at a skirting can wait, but water getting through can’t. If you’re unsure which you have, email us at info@mrmastic.co.uk with photos and we’ll tell you. 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.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

How the job changes by surface
Skirting and floors
As timber and screed dry, skirting and floors shift. We use a flexible product rather than caulk painted or coloured to suit.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one in a matching colour.

Why has my new-build shower seal failed already?
