Window mastic for homes and businesses in Stambourne Green
Homes in Stambourne Green have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have water coming in at the bottom corners of a door and old mastic that has gone black or come away, we can help, whatever the surface.
In a village or hamlet like Stambourne Green, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Every job comes with our one-year guarantee.

When it is not the sealant
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- A frame that has rotted at the joint
- Faulty window hardware
- Damp problems in the wall away from the window

What window mastic looks like in Stambourne Green
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours for a handful of frames, longer for a whole house. Somewhere like Stambourne Green needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Plan for the work area to be out of bounds to pets and children
- Clear the area around the work
- Tell us if parking is tricky

Signs you need window mastic in Stambourne Green
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
It’s worth asking for a quote if you see:
- Hard, cracked sealant around windows
- A bead that doesn’t match the frame
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
Around Stambourne Green, as everywhere, window mastic is only as good as the preparation behind it.

Different surfaces, different methods
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. It comes out, deep gaps get backing rod and the joint is resealed.
What happens if it’s left?
Getting a straight, even bead on an outside frame takes practice, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Stambourne Green, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
