Should I try it myself first?
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.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
About our window mastic in Ickenham
From a single sill to a whole house of windows, you’ll get a clear quote before work begins. Just phone 0345 464 0079 or drop us an email and tell us how many frames there are and how they’re reached for window mastic in Ickenham. We work on uPVC windows, window sills and patio & French doors, and people most often call us about damp patches on the reveal after heavy rain and cold air getting in at the frame edge.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Ickenham as anywhere.
The work is covered for a year after we finish. If anything isn’t right with it, ring 0345 464 0079 or email us.

The process
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the work takes anything from an hour or two to a full day, depending on how many frames there are in most cases. In a London area like Ickenham, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Preparing for the visit
- Mention any tricky access
- Mention any leaks or damp you’ve noticed
- Mention any sign-in or site rules at work premises

Frames and glazing around Ickenham
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. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Homes close to St Giles' Church include some older properties, and 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 The Douay Martyrs Catholic School, its window and door frames need their mastic kept sound, just like a home’s.

Looking after it afterwards
After the cure time, these simple habits help:
- Look round the frames every year or so
- Keep solvents and bleach off the sealant
- Make sure the drainage slots are not blocked
- Wipe condensation off the frames
Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.
What the job involves on each surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Window sills
The end joints of a sill tend to fail before the rest. We reseal them so rain can’t run into the wall.
Common problems we fix in Ickenham
Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
Look out for any of the following:
- Gaps between the frame and the inside reveal
- Cold air getting in at the frame edge
- Damp patches on the reveal after heavy rain
- Old mastic that has gone black or come away
If you let a flat or house near West Ruislip station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.
