About our window mastic in Finkley
Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the bead blends with the window rather than framing it. Common call-outs are for a bead that doesn’t match the frame and rushed sealant from a window installation, on timber windows & doors, uPVC windows and aluminium frames.
In a village or hamlet like Finkley, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
You get a 12-month guarantee, the same in Finkley as everywhere else we work.

DIY sealant or a professional job?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What we do, step by step
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes anything from an hour or two to a full day, depending on how many frames there are, depending on the size of the job. In a small place like Finkley, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
How to prepare
- Tell us about any water getting in
- Mention any parking rules near the property
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote
Getting a quote is simple: let us know the job and the location and its rough size. A few photos by email make the job easier to understand.

What sealant work can’t fix

Whether it’s one flat or a portfolio, you get the same standard of work: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Repaint timber before it’s bare
- Clean frames with a soft cloth and soapy water
- Ventilate rooms so frames don’t stay wet inside
- Check the mastic once a year
Most silicone sealants will not take paint, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
Draughts get worse, not better. As the old mastic shrinks further, more air gets through, and a cold room gets colder. Resealing closes it.

Window mastic in Finkley: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Smannell and Enham Church of England (Aided) Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Andover station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. In the older streets around Christ Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

What happens if it’s left?
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. Around Finkley, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
