New build mastic in Northfield
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, so sealant that was laid quickly before handover often cracks. Typical jobs include internal frame sealant that has split and beads laid onto grit and dust from the build, on plot handovers, kitchens and skirting & floors.
Older tenement flats normally have timber floors on joists, with skirting joints that open and close with the seasons. For a flat in Northfield, a flexible sealant copes with that movement where filler would crack.
We stand behind the work with a 12-month guarantee.

How the job changes by surface
Skirting and floors
New homes often develop a gap between skirting and floor. A flexible sealant closes it without cracking like caulk.
Windows and doors
On new builds, external frame sealant can be patchy. It’s resealed with an exterior sealant suited to the frame and wall.
What happens on the day
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 normally takes a few hours for most snagging lists, longer for a run of plots. For a tenement in Northfield, work inside your flat is between us and you, while shared parts may need the factor or neighbours to agree. Tell us which applies when you book.
- We start by agreeing which joints are on the list, from the snagging sheet or plot schedule.
- Failed or untidy sealant is cut out completely.
- We clean off dust from the build and prime the surfaces where the product needs it.
- We apply a sealant that suits each joint and tool it to a neat finish.
- We check every joint and tell you how long each needs to cure.
Getting ready for the visit
- Mention any parking rules near the property
- Plan for the work area to be out of bounds to pets and children
- Let us know about earlier repairs to the joints

Advice
Why deal with it now?
Resealing everything on a snagging list in one visit is generally simpler than chasing joints one at a time. You get one visit and one clear quote for the lot. In a Scottish city tenement, failed sealant affects more than one flat: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.
Combining jobs into one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Joints and finishes in Northfield homes
Northfield is within about 2 miles of the coast. Plot mastic on new homes near the coast takes more weather than it would inland, so it’s worth checking at snagging. Timber frame is common in newer Scottish homes, so skirting and sealant joints can open up as the building settles.
For new homes near Brunstane station, it’s worth checking the sealant early, while snags are still fresh.

Do you need new build mastic in Northfield?
On many sites, sealant goes on in the final rush before handover. Dusty, unprimed joints are common, so the bead never bonds properly.
Any of these means the joints need attention:
- Leaking shower tray seals in a new home
- Internal frame sealant that has split
- Kitchen sealant that has pulled off the wall
- Gaps between new skirting and floors
Around Northfield, as everywhere, new build mastic is only as good as the preparation behind it.
