About our window mastic in Acton
The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you have draughty joints inside around the window and rushed sealant from a window installation, we can put it right.
Mastic can only go onto a dry, clean joint, so window work in Acton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
There’s a 12-month guarantee on every job, whatever its size.

Why deal with it now?
If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Around Acton, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
The cost reflects the work involved, not guesswork. That’s why we ask about the job first and give you a clear quote before we start.
Why us?
- Every job guaranteed for a year

What happens on the day
At the end, we look at the finished work together and explain the cure time. The visit itself normally takes a few hours for a few frames, or a day or more for a whole house, depending on the amount of work. Somewhere like Acton needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- Each frame is looked over and we agree which ones need resealing.
- The old mastic is cut out and scraped back to clean surfaces.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Quotes for window mastic in Acton
There’s no set price list, because jobs vary so much. What we look at:
- Mould in or behind the old joints
- The size of the job
- The old material and how stubborn it is
- The number of rooms or windows
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.
Asking for a quote
You don’t need to know the technical terms. It helps if you can tell us:
- Whether it’s a home or a business
- Where the job is, and your postcode
- Any access issues, like height or stairs
- What’s wrong with the joints now
Need a quote? Please ring 0345 464 0079 or send us an email and tell us about the job. We’ll explain what we’d do and give you a clear price before we start.
Window mastic in Acton: local notes
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. Historic houses like Smallhythe Place (about 1.5 miles north-west) are a reminder that the area around Acton 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.
If you let a flat or house near Appledore (Kent) station, renewing tired window mastic between tenants heads off draught and damp complaints. Schools such as Wittersham Church of England Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as Parish Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Your questions about window mastic in Acton
Do you cover smaller places like Acton?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can you do window mastic in Acton?
Yes. Our work covers London and the South East, and Acton is part of that. You can ring 0345 464 0079 or send us an email and tell us what needs doing.
When is the sealant fully cured?
Different products cure at different speeds, so follow the cure time we give you.
Is the work guaranteed?
Yes. Our 12-month guarantee covers every job.
How many windows can you do in a day?
That depends on the number of frames, how they’re reached and the state of the old mastic. You’ll know the timing when we quote.
I rent my home. Can I book you?
Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.
Can you do the inside joint as well?
Yes. The outside joint keeps the weather out, and the inside joint stops draughts and finishes the reveal. We can do either or both.

We also work for property managers and facilities teams. We can quote a run of properties together.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.
Surface by surface
Composite doors
An exposed front door gets wind-driven rain. Those corners get the most care.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
