Burwash Weald Window Mastic
We cover Burwash Weald for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.
- Gaps left after new windows were fitted
- Draughts coming in around windows and doors
- Mastic that is falling out in pieces
Surface by surface
Composite doors
If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We seal the frame and let you know about anything else.
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour suits the frame.
Window mastic in Burwash Weald, done properly
Around Burwash Weald we seal all kinds of frames: from uPVC casements to timber and aluminium, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on uPVC windows, timber windows & doors and patio & French doors, and common reasons people get in touch are gaps left after new windows were fitted and cracked sealant at the sill ends.
Mastic can only go onto a dry, clean joint, so window work in Burwash Weald is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a morning for a couple of windows and a door, depending on the size of the job. Somewhere as small as Burwash Weald, 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.
- Old, cracked mastic is removed completely.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Keep pets and children clear of the area while we work
- Clear items away from the joints we’re working on

Will there be a smell?
That depends on the sealant. Some products have a noticeable smell, others very little.

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

Window mastic in Burwash Weald: local notes
With historic houses such as Bateman's (about 0.9 miles east) nearby, there’s older building stock in the area around Burwash Weald as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around St Philip's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why act early in Burwash Weald
Choosing the product is half the job. Decorators’ caulk and bathroom silicone are not designed for outside joints that move. An exterior, low-modulus sealant stays flexible in sun and frost. Older cottages and farmhouses around Burwash Weald can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Make sure the drainage slots aren’t blocked
- Look round the frames every year or so
- Wash the frames with mild soapy water
- Don’t aim a pressure washer at the joints
On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Keep paint off the silicone itself.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Early resealing stops it reaching that point.
