Willingale Window Mastic
We cover Willingale for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and every job guaranteed for a year.
- Mastic that has split away from the wall
- White mastic on grey or black frames
- Gaps where the sill meets the wall
Keeping the joints in good condition
A little care helps the new joints last. Our advice:
- Avoid harsh chemicals near the mastic
- Ventilate rooms so frames don’t stay wet inside
- Keep paint off silicone joints
- Keep jet washers away from the mastic
Silicone can’t generally be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Signs to watch for: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
About our window mastic in Willingale
There are two joints on most windows. The external joint is the weather seal; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you are dealing with draughty joints inside around the window and old mastic that has gone black or come away, we can put it right.
Around Willingale, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
A 12-month guarantee comes as standard, so you are covered after we have gone.

Surface by surface
Composite doors
Front doors take the weather head on, and the top and bottom corners tend to fail first. Those corners get the most care.
uPVC windows
Plastic frames move a lot between a hot afternoon and a cold night, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.

What we are called out for in Willingale
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- Cracked sealant at the sill ends
- Whistling draughts around closed windows
- Cracked internal joints between frame and plaster
- Untidy mastic left by window fitters
For an older house near a landmark such as Parish Church of St Christopher Willingale Doe, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Questions to ask before you book
- Whether they’re fully insured
- What preparation is included
- How long to leave it before use
- Is VAT in the price?
Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again.
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.

What we do, step by step
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere like Willingale needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
Getting ready for the visit
- Let us know about stairs, lifts or work at height
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit
