Different surfaces, different methods
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
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.
How we handle window mastic in Trotton
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. The old mastic is removed and the joint resealed with a flexible exterior sealant. Typical jobs include damp patches on the reveal after heavy rain and untidy mastic left by window fitters, on composite doors, aluminium frames and uPVC windows.
Homes in small places like Trotton often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Frames and glazing around Trotton
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Cowdray House (about 3.2 miles east) are a reminder that the area around Trotton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St George's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

It depends on the product. Before we leave, we’ll tell you the cure time.
Can you do upstairs windows?

Will resealing my frames help with draughts?
Yes, where the draught is at the frame edge. We check where the draught is before any work starts.
Can I do it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What we are called out for in Trotton
Older frames were often sealed with products that set hard. Once it’s rigid, every bit of frame movement pulls at it, and a gap opens along one edge.
Common reasons people contact us are:
- Untidy mastic left by window fitters
- Gaps where the sill meets the wall
- Damp patches on the reveal after heavy rain
- Mastic that has split away from the wall
If you look after a building such as Stedham Primary School, the mastic around its windows and doors needs looking after like any other building’s.

- How long to leave it before use
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a small place like Trotton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

What we cannot put right
Some problems need a builder, plumber or other trade rather than us:
- A failed sealed unit that has misted up
- Rotten timber, which needs a joiner first
- Draughts through the window seals rather than the frame
If in doubt, call 0345 464 0079 or email us and we will say what we think.

How to look after the new joints
Simple care keeps the joints in good condition. Our advice:
- Clean frames with a soft cloth and soapy water
- Ventilate rooms so frames don’t stay wet inside
- Look round the frames every year or so
- Don’t aim a pressure washer at the joints
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
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. Catching it early keeps the fix to a reseal.
