What window mastic looks like in New Hinksey
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Holywell Manor (about 1.4 miles north) nearby, there’s older building stock in the area around New Hinksey as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Church of St John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as New Hinksey Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to Oxford station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

- Soft or decayed wood in the frame

The process
Before we leave, we go over the finished joints with you and explain the cure time. The work normally takes most of a day for a typical house, less for a few frames, depending on how much there is to do. Parking around New Hinksey is usually easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.
- We clear up and check every joint is fully closed.
How to prepare
- Keep pets and children clear of the area while we work
- On commercial sites, let us know about site rules
- Tell us about any water getting in

How to look after the new joints
Aftercare is simple:
- Wash the frames with mild soapy water
- Air rooms to keep condensation down around windows
- Make sure the drainage slots aren’t blocked
- Paint up to the joint, not over it
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Paint up to the joint, not over the silicone.
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.

Different surfaces, different methods
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We will tell you which suits your home.
Window sills
Sills catch the water running down the glass, so the joints at each end and underneath matter. Each is cleaned out and resealed.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
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 fails, we can still redo it.
Leave it or put it right?
Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. Around New Hinksey, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
There are no prices on our website, because the cost depends so much on the job itself. Call for a quick quote and we will talk you through it.
