What happens on the day
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Somewhere as small as Marsh Baldon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Every joint is checked before we leave.

Advice
Window mastic for homes and businesses in Marsh Baldon
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you have gaps where the sill meets the wall and a bead that doesn’t match the frame, we can help, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Marsh Baldon is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
All our work comes with a one-year guarantee.

What sealant work can’t fix
In fairness, there are a few things sealant will not fix:
- Worn gaskets, brush seals or a door that has dropped
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
If in doubt, call 0345 464 0079 or email us and we’ll say what we think before you book.

Window mastic in Marsh Baldon: local notes
With historic houses such as Garsington Manor (about 2.2 miles north-east) nearby, there’s older building stock in the area around Marsh Baldon 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For landlords with property near Radley station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Church of St Peter include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What the job involves on each surface
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. We match white, brown, anthracite grey and black frames.
Composite doors
Draughts round the door leaf usually come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.

Every job gets its own quote. These are the things that affect it:

What happens if it’s left?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Older cottages and farmhouses around Marsh Baldon can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

When to call us in Marsh Baldon
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the brick or render around it hardly moves. A sealant that can’t keep up eventually tears.
Any of these means the joints need attention:
- Hard, cracked sealant around windows
- Cracked sealant at the sill ends
- Draughts coming in around windows and doors
- Draughty joints inside around the window
If you look after a building such as Marsh Baldon Church of England Controlled School, its window and door frames need their mastic kept sound, just like a home’s.
