Joints and finishes in Gilmerton homes
Many new homes in Scotland are timber-framed, so skirting and sealant joints can open up as the building settles.
Whether the job is in Gilmerton itself or nearby, the right material for each joint matters as much as a neat finish.

How we handle new build mastic in Gilmerton
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water reaches anything behind it. If you have kitchen sealant that has pulled off the wall and leaking shower tray seals in a new home, we can put it right.
New homes in smaller Scottish places are often single plots, self-builds or small developments. Each needs its sealant and floor joints finished as carefully as on a big site.
Our work is backed for twelve months.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Act quickly if a seal starts to leak
- Clean sealant with mild detergent, not abrasives
- Watch for new gaps as the house dries out
- Report sealant problems to your builder during the snagging period
Watch the joints as the house settles. Small gaps can appear as the house dries and can be resealed later.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
The process
We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours in a single home, and the area is left clean. Somewhere like Gilmerton may be a longer drive, and the journey is planned ahead. Mention tracks, gates, ferries or anything else about the route.
- We start by going through the snagging items or plot schedule with you.
- Every bit of the old builder’s sealant is cut out.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- We tool every joint neatly and tell you when each area can be used.
How to prepare
- Keep children and pets away from the work area
- Try not to wet indoor joints just before the visit
- Let us know about parking restrictions

What we’re called out for in Gilmerton
On many sites, sealant goes on in the final rush before handover. Joints are not always cleaned of dust or primed, so the bead never bonds properly.
People usually contact us after spotting one of these:
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
- Shower seals failing in the first year or two
- Gaps between new skirting and floors
In and around Gilmerton, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.

Honest limits
In fairness, there are a few things sealant won’t fix:
- Plumbing faults behind the sealant
- Movement caused by a poorly fitted tray or bath
- Settlement cracks that need a surveyor
