Window & door mastic in South Ealing, Greater London
Professional window mastic in and around South Ealing, with old sealant always removed completely.

How we handle window mastic in South Ealing
Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. If you have cold air getting in at the frame edge and mastic that has split away from the wall, we can put it right.
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 South Ealing as anywhere.
You get a one-year guarantee, the same in South Ealing as everywhere else we work.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Keep paint and stain on wooden frames in good order
- Air rooms to keep condensation down around windows
- Keep jet washers away from the mastic
- Paint up to the joint, not over it
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
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. If you notice one, it’s time to get the joint looked at.
DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Windows and doors in South Ealing
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
South Ealing is in London, so parking needs planning: let us know about parking bays, permits or a driveway. For an older house near a landmark such as St Mary's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. If you look after a building such as Grange Primary School, the mastic around its windows and doors needs looking after like any other building’s.

Common questions in South Ealing
I let a flat near Brentford station. Can you help?
Yes. We work for landlords and agents as well as householders. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is parking a problem for a job in South Ealing?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Will new mastic stop draughts?
It will if the frame joint is the problem. We check where the draught is before we start.
Will it make a mess?
No. The area is protected while we work and cleaned up afterwards.
Can you get sealant to suit coloured frames?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Do you work on first-floor windows?
Yes, where they can be reached safely. Let us know about access when you ask for a quote and we will plan for it.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we’ll tell you what we’re using.
How many windows can you do in a day?
A few frames take a few hours, while a whole house takes longer. We confirm the timing with your quote.
What we do, step by step
Good joint work is mostly preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. For a job in South Ealing, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- First, we confirm safe access to each frame.
- All the failed sealant is cut away.
- The surfaces are cleaned and left dry.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about stairs, lifts or work at height
- Mention any parking rules near the property

Work for landlords, hotels and businesses
For anyone letting property in or around South Ealing, several properties can be quoted together. Just tell us the addresses and what each one needs.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
Why act early in South Ealing
Failed mastic isn’t a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that is needed. If we find failed glass units or worn seals, we will tell you. In a flat in South Ealing, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
Why book with us
- We leave the area clean and tidy
- Sanitary silicone with an anti-fungal additive in wet areas
- White, clear, grey or coloured to suit, where the product allows
- A sealant colour to suit the surroundings
