New Build Mastic in Mambeg

- Internal frame sealant that has split
- Shower seals failing in the first year or two
- Plot mastic for developers ahead of handover
New build mastic in Mambeg, done properly
We never seal over a failed new-build bead. Fresh silicone can’t bond to the old layer, so it all comes out before we clean, dry and reseal. If you have untidy sealant flagged on a snagging list and plot mastic for developers ahead of handover, we can help, whatever the surface.
For a place like Mambeg, the journey and access are planned in advance. Outdoor plot mastic needs dry weather, but indoor floor and skirting joints can be sealed whatever the forecast.
Every job is covered by a 12-month guarantee.

What we cannot put right
It helps to know what we cannot do:
- Baths and trays that move too much for sealant to cope with
- Settlement cracks that need a surveyor

Leave it or put it right?
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. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.

Signs you need new build mastic in Mambeg
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
It’s worth asking for a quote if you see:
- Messy sealant that spoils new finishes
- Frame joints opening as the plaster dries
- Second-fix sealing on new plots
- Leaking shower tray seals in a new home
Around Mambeg, as everywhere, new build mastic is only as good as the preparation behind it.

How the visit works
We keep the work tidy and contained to the area we’re working on. Expect the work to take anything from a few hours to several days, depending on the number of plots, and we explain the cure time before we leave. Outdoor work around Mambeg depends on the weather, as sealant needs a dry surface, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- 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 down to clean surfaces.
- Joints are vacuumed and cleaned of building dust.
- Primer goes on where the surface and product need it, then the new sealant.
- Each bead is tooled and the cure times explained.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about stairs, lifts or work at height
- Let us know if you’ve seen damp or leaks
