Can I do it myself?
A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Window mastic in Bilting
Behind a thin line of old mastic there’s sometimes a deep void. Filling it with sealant alone leaves a joint that can’t move properly, so deep gaps get backing rod first. That way the new bead bonds to the frame and the wall only. We work on uPVC windows, composite doors and patio & French doors, and the jobs we see most are old mastic that has gone black or come away and hard, cracked sealant around windows.
Somewhere as small as Bilting, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Big or small, it’s backed by our one-year guarantee in Bilting and across Kent.

What window mastic looks like in Bilting
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as Wye School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Wye station, renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as Church of St Lawrence, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the job changes by surface
Window sills
Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
Aluminium frames
Bi-fold and sliding aluminium doors have long frame joints, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.
Leave it or put it right?
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. In a small place like Bilting, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

The process
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the job takes a morning for a couple of windows and a door in most cases. For a village or hamlet like Bilting, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- We fit backing rod in deep gaps so the sealant is the right depth.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- We clear up and check every joint is fully closed.
Preparing for the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on
- Let us know if you’ve seen damp or leaks

Looking after it afterwards
Good habits help new joints last longer. Our tips:
- Wipe condensation off the frames
- Do not paint over the silicone
- Keep solvents and bleach off the sealant
- Repaint timber before it’s bare
Silicone cannot generally be painted, so if you’re planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

What should I tell you?

Will the old sealant be removed?
Always. Sealing over old sealant is the main reason resealing fails early, so we never do it.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
