What affects the cost of new build mastic

- How easy the joints are to reach
- Any mould that needs treating
- How many rooms, windows or areas are involved

How we handle new build mastic in Stonehill Green
Developers send us the plot schedule and we work through it. Bathrooms, en suites, kitchens, frames and skirting are sealed ready for handover. We’re often asked to deal with shower seals failing in the first year or two and cracks appearing as a new home settles, across bathrooms & en suites, plot handovers and skirting & floors.
In a village or hamlet like Stonehill Green, new homes are more likely to be a barn conversion or a handful of houses than a big estate. Each still needs its sealant and floor joints finished properly.
Our work is backed for twelve months.

How to look after the new joints
Good habits help new joints last longer. Our tips:
- Avoid scourers and strong chemicals on sealant
- Use the extractor fan every time you shower
- Record problems with dated pictures
- Raise failed sealant with the developer while you are covered
Follow the cure time we give you before the area gets wet. Most silicones need around a day to cure enough for use.
Lifting sealant traps moisture and mould behind it. Dealing with it before it goes black keeps the job straightforward.
Surface by surface
Show homes
In a show home, the sealant is on display. We lay neat, even beads in colours to suit the finishes.
Plot handovers
Good preparation at handover saves snagging later. Dust from the build is removed first.
How it works
Good joint work is mostly preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it generally takes a few hours for most snagging lists, longer for a run of plots. Somewhere as small as Stonehill Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, the list of joints is agreed from your snagging sheet or plot schedule.
- Every bit of the old builder’s sealant is cut out, with no layer left behind.
- Joints are vacuumed and cleaned of building dust.
- We prime where needed and apply a sealant suited to each joint.
- Each bead is tooled and the cure times explained.
Before we arrive
- Keep children and pets away from the work area
- Tell us about access, such as stairs, a lift or high-level joints
- Mention if the joints have been sealed before

Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
When to call us in Stonehill Green
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.
It’s worth asking for a quote if you see:
- Leaking shower tray seals in a new home
- Plot mastic for developers ahead of handover
- Kitchen sealant that has pulled off the wall
- Skirting joints opening in the first winter
If you’ve bought a new home near Swanley station, the sealant around baths, showers and frames is worth checking in the first year or two.

Why it’s worth doing now in Stonehill Green
A hairline gap at a skirting can wait, but water getting through cannot. If you’re unsure which you have, call 0345 464 0079 or email us with pictures. Where a wall is exposed, as many are in small places like Stonehill Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
