About our window mastic in Bolter End
Every window and door frame has a gap around it, and mastic is what closes it. When it cracks, hardens or pulls away, draughts and rain get in. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We work on timber windows & doors, uPVC windows and composite doors, and people most often call us about cracked or shrunken mastic around the frame and untidy mastic left by window fitters.
In a village or hamlet like Bolter End, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
There’s a 12-month guarantee on every job, large or small.

Window mastic in Bolter End: local notes
With historic houses such as West Wycombe Park House (about 2.2 miles north-east) nearby, there’s older building stock in the area around Bolter End as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Saunderton station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. If you live in an older home near Church of the Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Lane End Primary School, the mastic around its windows and doors needs looking after like any other building’s.

What the job involves on each surface
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.

How to look after the new joints
Looking after new joints is easy:
- Repaint timber before it’s bare
- Keep drainage slots and sill grooves clear
- Do not use solvent cleaners on the joint
- Look round the frames every year or so
Check the drainage slots in the frames are not blocked, so rain drains out rather than building up at the sealant.
Signs to watch for: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
When something else is needed
It helps to know what we cannot do too:
- Broken hinges, locks or handles
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
If in doubt, ring 0345 464 0079 or drop us an email and we will say what we think.
What we seal
- Composite doors
- uPVC windows
- Patio & French doors
- Timber windows & doors
- Aluminium frames
- Window sills
Why act early in Bolter End
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, in a sealant suited to the wall. Around Bolter End, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Combining jobs into one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will send you a clear quote for the lot.
