Window Mastic in Lower Haysden
Mastic around window and door frames, sills and patio doors for homes and businesses in Lower Haysden and across Kent. ARBOMaster approved applicators, fully insured, with a one-year guarantee.
- Rain getting in at the frame or under the sill
- Rushed sealant from a window installation
- Cracked sealant at the sill ends
How to look after the new joints
Looking after new joints is easy:
- Clean frames with a soft cloth and soapy water
- Walk round the house once a year and look at the joints
- Keep solvents and bleach off the sealant
- Keep jet washers away from the mastic
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water trapped behind a failed joint can start rot in timber frames and sills. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
How we handle window mastic in Lower Haysden
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you are dealing with rain getting in at the frame or under the sill and cold air getting in at the frame edge, we can put it right, on uPVC windows, aluminium frames and window sills alike.
Homes in small places like Lower Haysden 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Why it’s worth doing now in Lower Haysden
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 Lower Haysden, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote.

What window mastic looks like in Lower Haysden
With historic houses such as Penshurst Place (about 2.8 miles west) nearby, there’s older building stock in the area around Lower Haysden as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Sussex Road Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St Stephen's Mission Church, the joint between an old wall and a newer frame is generally the first place rain gets in. If you let a flat or house near Tonbridge station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What the job involves on each surface
uPVC windows
The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
