Mastic around window and door frames, sills and patio doors for homes and businesses in Plaistow Green and across Windsor and Maidenhead. ARBOMaster approved applicators, fully insured, with a 12-month guarantee.

- Water coming in at the bottom corners of a door
Window mastic in Plaistow Green
The new joint doesn’t have to be white. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. If you’re dealing with water coming in at the bottom corners of a door and gaps where the sill meets the wall, we can help, on patio & French doors, uPVC windows and composite doors alike.
Somewhere as small as Plaistow Green, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, whatever its size.

How the job changes by surface
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. If we find rot, we’ll tell you before going ahead, as that is a job for a joiner.
How it works
Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes a morning for a couple of windows and a door, and the area is left clean. For a village or hamlet like Plaistow Green, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky

Advice
What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Plaistow Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

For landlords and businesses
From a single let to a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
What we can’t put right
Before you book, it’s worth knowing the limits:
- A frame that has rotted at the joint
- Damp problems in the wall away from the window
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly.

Frames and glazing around Plaistow Green
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like St Leonard's Hill (about 2.5 miles north-east) are a reminder that the area around Plaistow Green 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.
If you live in an older home near Church of St Peter, the joint between an old wall and a newer frame is generally the first place rain gets in. Letting a property close to Ascot station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you look after a building such as Cranbourne Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
How long the joints last depends on use and care. Here’s what we suggest:
- Paint up to the joint, not over it
- Keep paint and stain on wooden frames in good order
- Clear any debris from frame drain holes
- Air rooms to keep condensation down around windows
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so it pays to reseal before that happens.
