Window mastic for homes and businesses in Upper Wellingham
A cold draught around a closed window often comes from the frame edge. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. If you have rain getting in at the frame or under the sill and old mastic that has gone black or come away, we can help, on patio & French doors, uPVC windows and aluminium frames alike.
Outdoor sealant needs dry, clean surfaces, so work on frames around Upper Wellingham is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, it’s backed by our one-year guarantee in Upper Wellingham and across East Sussex.

Signs you need window mastic in Upper Wellingham
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar didn’t grip properly, so it comes away long before its time.
These are the problems we are asked about most:
- Black, perished sealant on frames
- Cracked sealant at the sill ends
- Damp patches on the reveal after heavy rain
- Untidy mastic left by window fitters
Schools such as Ringmer Community College and Sixth Form are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What window mastic looks like in Upper Wellingham
The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Glyndebourne (about 2.2 miles south-east) are a reminder that the area around Upper Wellingham has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Letting a property close to Cooksbridge station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around The Parish Church of St Mary, the joint between an old wall and a newer frame is usually the first place rain gets in.

Surface by surface
Timber windows & doors
Soft or rotten wood cannot be sealed successfully. If we find rot, we will tell you before going ahead, as a joiner will need to deal with it.
Patio & French doors
Water at the foot of a door frame isn’t always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We check before we reseal.

When it is not the sealant

Leave it or put it right?
Failed mastic is not a reason to replace sound windows. Where the frames are sound, new mastic generally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Where a wall is exposed, as many are in small places like Upper Wellingham, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost reflects the work involved, not guesswork. That is why we ask a few questions first and agree the price before starting.
