The process
We keep the work tidy and contained to the joints we are treating. Expect the work to take a morning for a couple of windows and a door, and we tell you how long to leave it before we go. Somewhere like Midgham Green needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each window and door with you.
- We remove the old mastic and clean the frame and the wall.
- We fit backing rod in deep gaps so the sealant is the right depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
Before we arrive
- Mention any tricky access
- Plan for the work area to be out of bounds to pets and children
- Clear items away from the joints we’re working on

We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.

More services for Midgham Green
Different surfaces, different methods
Aluminium frames
Metal frames expand in the sun and are often slim, with little room for error. A tidy bead in anthracite grey, black or a matching colour keeps the clean look.
uPVC windows
uPVC expands and contracts noticeably with temperature, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.
Common problems we fix in Midgham Green
Sills take more water than any other part of a window, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.
People generally contact us when they notice one of these:
- Cold air getting in at the frame edge
- Mastic that is falling out in pieces
- Mastic that has split away from the wall
- A bead that doesn’t match the frame
For an older house near a landmark such as Church of St Matthew, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- When the joint can take water or movement
- What product goes in the joint
- How the joint is cleaned and prepared
- How the colour is chosen
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How to look after the new joints
Aftercare is simple:
- Avoid harsh chemicals near the mastic
- Do not aim a pressure washer at the joints
- Wash the frames with mild soapy water
- Don’t paint over the silicone
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.
What window mastic looks like in Midgham Green
