New build mastic in Carfin
New homes move as they dry out. Timber dries and shrinks, and baths and trays settle, and sealant applied in a hurry at handover can split. Typical jobs include untidy sealant flagged on a snagging list and skirting joints opening in the first winter, on windows & doors, skirting & floors and show homes.
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.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Surface by surface
Kitchens
Worktops in new homes can move slightly as the house dries, opening gaps behind the upstand. We reseal them with a flexible sealant.
Windows and doors
Internal joints between frames and plaster often crack as a new house dries. We remove cracked sealant and apply a flexible one in a matching colour.
What we can’t put right
Some problems need a builder, plumber or other trade rather than us:
- Leaks from pipes, valves or wastes, which need a plumber
- Cracked trays, tiles or worktops
- A tray or bath that isn’t properly supported, until it’s fixed
Not sure which it is? You can send an email to info@mrmastic.co.uk and we’ll tell you honestly before you book.

What we’re called out for in Carfin
If plaster or screed was still damp when it was sealed, the bond suffers. Site programmes do not always leave time for joints to dry before the sealant goes on.
Common reasons people contact us are:
- Second-fix sealing on new plots
- Gaps opening as the house dries out and settles
- Kitchen sealant that has pulled off the wall
- Sealant that never bonded to the surface
For new homes near Carfin station, it’s worth checking the sealant early, while snags are still fresh.
What your quote should include
- What product goes in the joint
- Whether all the old sealant comes out first
- What the cure time is
- Whether they’re fully insured
Aftercare tips
A little care helps the new joints last. We recommend:
- Get a leaking seal dealt with straight away
- Resist patching a failed seal with a tube from the DIY shop
- Raise failed sealant with the developer while you are covered
- Watch for new gaps as the house dries out
Do not stand on the bath edge or the lip of the tray. If a bath or tray moves when you stand in it, get it looked at.
Do not let the snagging period run out with sealant problems unreported. After that, putting it right may fall to you, so raise it early.
DIY sealant or a professional job?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

What else we do in Carfin
The process
When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes anything from a few hours to several days, depending on the number of plots. Somewhere like Carfin may be a longer drive, and the journey is planned ahead. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.
- First we work through your snagging list or plot schedule with you.
- The old bead comes out in full, with no layer left behind.
- 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.
- Finally, each room is checked and you are given the cure time.
Before we arrive
- Let us know if you’ve seen damp or leaks
- Clear items away from the joints we are working on
- Tell us about access, such as stairs, a lift or high-level joints
