About our window mastic in Hedgerley Green
The mastic around a window or door seals the gap between the frame and the wall. 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 composite doors, uPVC windows and window sills, and people most often call us about cracked internal joints between frame and plaster and draughts coming in around windows and doors.
Homes in small places like Hedgerley Green often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
Each job carries a 12-month guarantee.

Do you need window mastic in Hedgerley Green?
Every frame moves through the day. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
Any of these means the joints need attention:
- Whistling draughts around closed windows
- Rushed sealant from a window installation
- Leaking joints at the ends of sills
- Black, perished sealant on frames
Schools such as Gayhurst School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Why deal with it now?
If you are painting or rendering, reseal at the same time. Fresh joints finish the job neatly. Older cottages and farmhouses around Hedgerley Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
What it costs depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts.

What window mastic looks like in Hedgerley Green
With historic houses such as Cliveden (about 4.5 miles west) nearby, there’s older building stock in the area around Hedgerley Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Parish Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you let a flat or house near Gerrards Cross station, renewing tired window mastic between tenants heads off draught and damp complaints.

Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
- Don’t aim a pressure washer at the joints
- Repaint timber before it’s bare
Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Timber windows & doors
Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as that’s a job for a joiner.
Patio & French doors
Patio and French doors have the longest joints on most houses. The threshold and the bottom corners take the most water, so they get particular care.
