How it works
We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job usually takes anything from an hour or two to a full day, depending on how many frames there are, and we explain the cure time before we leave. Somewhere like Martyr Worthy needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check how each frame can be reached safely.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- We tool the joint so water runs off, then clear up.
Getting ready for the visit
- Mention any leaks or damp you’ve noticed
- Where the joints are inside, avoid wetting them before we arrive
- Move anything stored near the joints

Advice
Window mastic in Martyr Worthy
Whether it’s one leaking patio door or every frame on the house, you will get a clear quote before work begins. Just phone 0345 464 0079 or send us an email and tell us how many frames there are and how they’re reached. We work on window sills, composite doors and uPVC windows, and common reasons people get in touch are gaps where the sill meets the wall and rain getting in at the frame or under the sill.
Homes in small places like Martyr Worthy often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Why it’s worth doing now in Martyr Worthy
Getting a straight, even bead on an outside frame takes practice, especially on upper floors. We cut out properly, back deep gaps and tool every joint neatly, using a product chosen for the frame and wall. Around Martyr Worthy, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will go through it with you.

Do you need window mastic in Martyr Worthy?
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
The most common problems we see are:
- Gaps left after new windows were fitted
- Draughts coming in around windows and doors
- Cracked sealant at the sill ends
- Mastic that is falling out in pieces
If you live in an older home near Church of St Swithin, the joint between an old wall and a newer frame is normally the first place rain gets in.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Ventilate rooms so frames do not stay wet inside
- Keep paint off silicone joints
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
A yearly look round the frames is enough. Small splits are simple to catch before they leak, and if anything looks wrong, just call 0345 464 0079 or email us.
Leaks usually show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.
