What the job involves on each surface
Composite doors
A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.
uPVC windows
We clean the frame edge carefully so the plastic isn’t marked, then the new bead is laid against the frame and the wall and tooled smooth.

The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a morning for a couple of windows and a door in most cases. In a small place like Deane, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check how each frame can be reached safely.
- All the failed sealant is cut away, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing.
- Deep voids are backed, then the sealant is gunned in.
- The joint is shaped to shed water and the area tidied.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Mention if the joints have been sealed before
- Tell us about any water getting in

Common problems we fix in Deane
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
These are the problems we’re asked about most:
- Sealant in the wrong colour for the frame
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
- Rain getting in at the frame or under the sill
Homes close to Church of All Saints include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Aftercare tips
So the new joints stay in good condition:
- Check the mastic once a year
- Keep timber frames painted
- Make sure the drainage slots aren’t blocked
- Wash the frames with mild soapy water
Silicone can’t usually be painted, so if you’re planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.
Signs to watch for: 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.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
