Honest limits
It helps to know what we cannot do:
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)

Surfaces we seal
- uPVC windows
- Aluminium frames
- Composite doors
- Patio & French doors
- Timber windows & doors
- Window sills
Keeping the joints in good condition
So the new joints stay in good condition:
- Wipe condensation off the frames
- Check the mastic once a year
- Keep jet washers away from the mastic
- Make sure the drainage slots aren’t blocked
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Signs you need window mastic in Jarvis Brook
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
It’s worth asking for a quote if you see:
- Gaps where the sill meets the wall
- Damp patches on the reveal after heavy rain
- Hard, cracked sealant around windows
- A bead that doesn’t match the frame
Rented homes near Crowborough station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Frames and glazing around Jarvis Brook
With historic houses such as Groombridge Place (about 4.7 miles north) nearby, there’s older building stock in the area around Jarvis Brook as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
For an older house near a landmark such as St Michael & All Angels, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Jarvis Brook Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Related advice
What the job involves on each surface
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that without cracking.
Aluminium frames
Aluminium moves with heat, and the frames are often slimmer than uPVC. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
