New build mastic in Newington
Across Newington, we work for both new-home owners and the builders handing those homes over. One shower or a whole phase of plots, the method doesn’t change: remove, clean, prime where needed, then a neat new bead. If you’re dealing with second-fix sealing on new plots and worktop and upstand sealant coming away, we can help, on plot handovers, windows & doors and kitchens alike.
Older tenement flats usually have timber floors on joists, with skirting joints that open and close with the seasons. For a flat in Newington, a flexible sealant copes with that movement where filler would crack.
A one-year guarantee comes with the work, just as it does everywhere we cover.

When to call us in Newington
Sealant is often one of the last jobs before handover. Joints are not always cleaned of dust or primed, and the sealant sits on grit instead of the surface.
Look out for these signs:
- New-build shower sealant that has already split
- Gaps opening as the house dries out and settles
- Sealant work across a run of new homes
- Cracked caulk along new skirting
For new homes near Edinburgh Waverley station, it’s worth checking the sealant early, while snags are still fresh.
Questions to ask before booking
- When the joint can take water or movement
- What happens if the job turns out different
- What guarantee comes with the work
- Whether all the old sealant comes out first

New build mastic around Newington
Newington 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. Many new homes in Scotland are timber-framed, and as the frame dries and settles, skirting and sealant joints can open up.
Around Newington, as everywhere, new build mastic is only as good as the preparation behind it.

When something else is needed

- Cracked trays, tiles or worktops
- Cracking that points to a structural problem
Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Why it’s worth doing now in Newington
DIY kits do not solve the main problems with new-build sealant: dust, no primer and old sealant left in the joint. Proper removal and preparation are what make it last. Wind-driven rain gets into any failed joint on the outside of a city building, and in Newington, damp can spread through stone and plaster before anyone sees it.
We do not show prices on the website, because each job is priced on what it involves. For a quick quote, please send an email to info@mrmastic.co.uk and we will talk you through it.

DIY sealant or a professional job?
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.
