Woodley Window Mastic
Window mastic for Woodley, by sealant specialists with 20+ years’ experience. Rated 4.9 on Google from 180+ five-star reviews.
- Gaps between the frame and the inside reveal
- Cracked or shrunken mastic around the frame
- A bead that doesn’t match the frame
Aftercare tips
To keep the joints looking good and working properly:
- Wash the frames with mild soapy water
- Air rooms to keep condensation down around windows
- Keep jet washers away from the mastic
- Keep paint and stain on wooden frames in good order
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
Window mastic in Woodley
Frames and walls don’t move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. If you have old mastic that has gone black or come away and sealant in the wrong colour for the frame, we can help, whatever the surface.
In a town like Woodley, the windows on the most exposed side of a house take the brunt of the rain, and that’s normally where the sealant gives up first. It’s worth looking at every frame, not just the one that leaks.
There’s a 12-month guarantee on every job, large or small.

DIY versus a professional finish
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Why act early in Woodley
The work is quick compared with the damage it prevents: it takes a few hours for a few frames, or a day or more for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. In Woodley, as anywhere, most leaks start as a small gap in a joint, and they’re far easier to fix early.
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

Different surfaces, different methods
uPVC windows
Some uPVC windows were sealed at fitting with a quick bead that never bonded. We cut it out, back any deep gaps and reseal properly.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain cannot run into the wall.
Windows and doors in Woodley
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Letting a property close to Winnersh Triangle station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. In the older streets around United Reformed Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Can new window sealant be painted?
It depends on the sealant. Silicone isn’t paintable, but some hybrid sealants are. Mention any painting plans before we start.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.

Signs you need window mastic in Woodley
Plenty of failed mastic was poorly applied in the first place. Sealant run over dust, wet brick or loose mortar never bonded as it should, and it lets go sooner than it should.
Common reasons people contact us include:
- Cracked or shrunken mastic around the frame
- Rain getting in at the frame or under the sill
- Cold air getting in at the frame edge
- Gaps where the sill meets the wall
Managing a site like Rivermead Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
