Should I try DIY first?

No. Fresh sealant doesn’t stick to old sealant, and it traps any mould or water underneath. It all has to come out first.

What happens if it’s left?
Running fresh sealant over the old joint is tempting, but new sealant can’t bond to old, crumbling mastic. It peels before long, and water still gets in behind. The old mastic has to come out. Around Parslow's Hillock, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost depends on the size of the job, how hard the old material is to remove and access to the work. We give a clear quote before work begins.

- Black, perished sealant on frames
- Mastic that has split away from the wall
- Rain getting in at the frame or under the sill

Window mastic in Parslow's Hillock: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hughenden Manor (about 4.6 miles south-east) are a reminder that the area around Parslow's Hillock has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
Schools such as Princes Risborough School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Princes Risborough station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Related advice
Keeping the joints in good condition
Aftercare is simple:
- Avoid harsh chemicals near the mastic
- Air rooms to keep condensation down around windows
- Make sure the drainage slots are not blocked
- Look round the frames every year or so
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. Any of these is worth a call.

What else we do in Parslow's Hillock
How the job changes by surface
Aluminium frames
Coated aluminium needs a compatible sealant, and acetoxy silicones are not used, as they can attack some metals. We use a neutral-cure product.
Window sills
Sills catch the water running down the glass, so the sill ends and the joint under the frame are vital. Each is cleaned out and resealed.
