New build mastic in Seton, done properly
Dust is the enemy of new-build sealant. Each joint is cleaned of dust and primed where the product calls for it, so the new bead bonds properly rather than sitting on a layer of grit. Typical jobs include smeared, uneven beads picked up at snagging and skirting joints opening in the first winter, across kitchens, show homes and skirting & floors.
Work in a place like Seton is planned ahead, journey included. Inside work goes ahead in any weather; outside mastic needs a dry day.
Whatever the size of the job, it’s backed by our one-year guarantee.

Your questions about new build mastic in Seton
Will you come out to Seton?
Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.
Can you do new build mastic in Seton?
Yes. We work across all of Scotland, and Seton is part of that. Just drop us a line at info@mrmastic.co.uk with a few details of the job.
Who should fix failed sealant in a new build?
Your builder, if you’re still in their snagging or warranty period. If that does not work out, we are happy to quote.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint before applying anything new.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We will tell you what we are using and why.
When is the best time to reseal in a new build?
Where water is getting through, don’t wait. Small gaps that are just cosmetic can be resealed once movement has slowed.
Where do you work from?
We work from Crawley. We cover Seton and the rest of East Lothian.
Signs you need new build mastic in Seton
The wrong product is sometimes used in the wrong place: caulk where water collects, or a rigid product on a moving joint. Neither lasts long.
If you can see any of these, it’s time to have the joints looked at:
- Sealant work across a run of new homes
- Gaps opening as the house dries out and settles
- Gaps between new skirting and floors
- Shower seals failing in the first year or two
Around Seton, as everywhere, new build mastic is only as good as the preparation behind it.

- Cracking that points to a structural problem
- Broken tiles or a split tray
- Leaks from pipes, valves or wastes, which need a plumber

DIY versus a professional finish
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the job changes by surface
Windows and doors
External mastic around new windows and doors is sometimes rushed or missed. It’s resealed with an exterior sealant suited to the frame and wall.
Kitchens
Worktops in new homes can move slightly as the house dries, which opens gaps along the back. A fresh flexible bead closes them.
For landlords and businesses
We work for landlords and letting agents as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order.
Whether it’s one flat or a portfolio, the work is the same standard: the old material taken out, careful preparation and a 12-month guarantee.

What new build mastic looks like in Seton
Seton is close to the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For new homes near Prestonpans station, it’s worth checking the sealant early, while snags are still fresh.

Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Clean sealant with mild detergent, not abrasives
- Record problems with dated pictures
- Follow the cure time we give you
- Watch for new gaps as the house dries out
Ventilation matters in a new home, which is still drying out. Use the extractor fan or open a window after showers so moisture does not sit on the sealant.
Report failed sealant to the builder while you’re in the snagging period. Once it ends, the repair may be down to you so report it promptly.
How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, carry out the job and tidy away. It generally takes a few hours in a single home.

- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- New sealant suited to each joint is applied and tooled neatly.
- We check every joint and tell you how long each needs to cure.
Before we arrive
- Tell us about any water getting in
- Tell us about access, such as stairs, a lift or high-level joints
- Try not to wet indoor joints just before the visit
