How we handle window mastic in Great Bardfield
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include water coming in at the bottom corners of a door and cracked sealant at the sill ends, on aluminium frames, uPVC windows and patio & French doors.
Somewhere as small as Great Bardfield, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Different surfaces, different methods
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.

Do you need window mastic in Great Bardfield?
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
The most common problems we see are:
- Old mastic that has gone black or come away
- Sealant in the wrong colour for the frame
- Draughty joints inside around the window
- Leaking joints at the ends of sills
If you look after a building such as Great Bardfield Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
What your quote should include
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
- How long to leave it before use
- Who turns up on the day
Leave it or put it right?
Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. In a small place like Great Bardfield, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.
What you get with us
- An ARBOMaster approved applicator
- More than 20 years in sealant work
- Arbo and Everbuild products
- We leave the area clean and tidy

Window mastic in Great Bardfield: local notes
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Parish Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works

In total, it normally takes most of a day for a typical house, less for a few frames. Somewhere as small as Great Bardfield, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Let us know about parking restrictions
- Try not to wet indoor joints just before the visit
