Tylers Green homes and the weather
With historic houses such as Hughenden Manor (about 2.4 miles west) nearby, there’s older building stock in the area around Tylers Green 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. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near High Wycombe station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you live in an older home near Church of St Margaret, the joint between an old wall and a newer frame is generally the first place rain gets in.

- A failed sealed unit that has misted up

Aftercare tips
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid harsh chemicals near the mastic
- Keep drainage slots and sill grooves clear
- Paint up to the joint, not over it
- Walk round the house once a year and look at the joints
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 old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.
Can I do it myself?
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.
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.

How the visit works

- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
How to prepare

Related advice
Common problems we fix in Tylers Green
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
The problems people usually mention when they call include:
- Cracked or shrunken mastic around the frame
- Damp patches on the reveal after heavy rain
- Rushed sealant from a window installation
- Old mastic that has gone black or come away
For site and facilities teams at buildings such as Manor Farm Community Infant School, the mastic around its windows and doors needs looking after like any other building’s.
