How the job changes by surface
Window sills
Every drop off the glass ends up on the sill, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.
Patio & French doors
Heavy door frames can move more than windows. The sealant must cope with it without cracking.
How we handle window mastic in Sheepdrove
Homes in Sheepdrove have every kind of window: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on timber windows & doors, window sills and uPVC windows, and common reasons people get in touch are sealant in the wrong colour for the frame and cracked sealant at the sill ends.
Mastic can only go onto a dry, clean joint, so window work in Sheepdrove is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
A 12-month guarantee comes as standard.

How to look after the new joints
After the cure time, these simple habits help:
- Keep timber frames painted
- Wipe condensation off the frames
- Keep solvents and bleach off the sealant
- Clean frames with a soft cloth and soapy water
Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.
Leaks generally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

What sealant work cannot fix
We will not take on work that will not last, so these are the limits:
- Damp coming through the wall itself rather than the frame joint
- A failed sealed unit that has misted up
- Faulty window hardware

When to call us in Sheepdrove
Frames are never completely still. A plastic or aluminium frame lengthens in sunshine and shortens as it cools, while the brick or render around it hardly moves. If the sealant cannot stretch, it splits.
Look out for these signs:
- Gaps between the frame and the inside reveal
- Mastic that is falling out in pieces
- A bead that doesn’t match the frame
- Rain getting in at the frame or under the sill
Around Sheepdrove, as everywhere, window mastic is only as good as the preparation behind it.
Questions to ask before you book
- Who turns up on the day
- How the surfaces are prepared before sealing
- Is VAT in the price?
- Which sealant they’ll use, and why
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What window mastic looks like in Sheepdrove
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Ashdown House (about 3.9 miles west) are a reminder that the area around Sheepdrove has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For an older house near a landmark such as Church of St Michael and All Angels, the joint between an old wall and a newer frame is normally the first place rain gets in.
