What we do, step by step
Good joint work is mostly preparation, and we do not rush it. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours for a few frames, or a day or more for a whole house. In Ealing, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- First, we go round the frames with you and agree the list.
- We remove the old mastic and clean the frame edge and wall.
- Where the gap is deep, backing rod goes in first.
- The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
- Mention if the joints have been sealed before
- Let us know about parking restrictions
- Mention any tricky access

Window mastic in Ealing, done properly
Homes in Ealing have every kind of window: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. If you have cracked internal joints between frame and plaster and untidy mastic left by window fitters, we can put it right, whatever the surface.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out, in Ealing as anywhere.
Each job carries a 12-month guarantee.

Honest limits
We won’t take on work that will not last, so here’s what sealant cannot put right:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- A door that needs adjusting, rehanging or new seals
- Penetrating damp from a failed cavity tray or render
If in doubt, call 0345 464 0079 or drop us an email and we’ll say what we think before booking.
Surfaces we seal
- Composite doors
- uPVC windows
- Window sills
- Timber windows & doors
- Aluminium frames
- Patio & French doors
Landlords, agents and businesses in Ealing
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can be quoted together.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What affects the cost of window mastic
There’s no set price list. The quote depends on:
- Which sealant suits the joint
- How much old sealant there is and how hard it is to remove
- How many areas need sealing
- Whether there’s mould to deal with
Doing several joints on one visit generally makes better use of the time than several visits, so tell us about everything that needs sealing. You’ll get one clear quote for the whole job.
Asking for a quote
To make quoting easier, let us know:
- How we’d reach the joints
- What the problem is, such as mould, gaps, leaks or cracking
- Whether it’s a home or a business
- Where the job is, and your postcode
It all starts with a short chat. Describe the problem, the location and the size of the job. Whenever you’re ready, call 0345 464 0079 or send us an email.
DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Why deal with it now?
The work is quick compared with the damage it prevents: the visit takes a few hours for a handful of frames, longer for a whole house. Leave it until water is coming in and you may need plastering and decorating as well. Damp from a failed joint spreads quietly in older London brickwork and timber, and by the time it shows on a wall or ceiling in Ealing, the repair is bigger than the sealant job would have been.
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
Why us?
- Tidy, careful work
- A sealant colour to suit the surroundings
- Old sealant always removed completely
- Sanitary silicone with an anti-fungal additive in wet areas

Ealing homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Pitzhanger Manor (about 0.1 miles east) are a reminder that the area around Ealing has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Ealing Broadway station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Ealing Independent College are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. As a London address, Ealing can be tricky for parking: let us know about parking bays, permits or a driveway.

Aftercare tips
Once the sealant has cured, a few habits help it last:
- Use gentle cleaners on frames and sealant
- Repaint timber before it’s bare
- Do not aim a pressure washer at the joints
- Don’t use solvent cleaners on the joint
Keep sill grooves and drainage slots clear, so rain drains out rather than building up at the sealant.
Water gets in quietly when mastic fails. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Your questions about window mastic in Ealing
Can parking be tricky for a visit in Ealing?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
I let a flat near Ealing Broadway station. Can you help?
Yes, landlords and agents are among the people we work for. You can ring 0345 464 0079 or email us with the details for a clear quote.
What sealant do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Do you work in Ealing?
Yes. We work in Ealing, as part of our work across South East England, London and Scotland. To book, phone 0345 464 0079 or send us an email.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Do you take out the old sealant first?
Yes, every time. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
Can new sealant go over the old?
No. We remove every bit of old sealant first.
Does the work come with a guarantee?
Yes, with our 12-month guarantee. A yearly look at the joints helps them last.
