Window & door mastic in Dagenham Dock, Greater London
Window and door frames in Dagenham Dock need attention? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Cracked sealant at the sill ends
- Cracked internal joints between frame and plaster
- Mastic that is falling out in pieces
Window mastic for homes and businesses in Dagenham Dock
Most frames have an outside joint and an inside one. The external joint is the weather seal; inside, the joint between frame and plaster stops draughts and tidies the reveal. Either or both can be done. If you are dealing with untidy mastic left by window fitters and a bead that doesn’t match the frame, we can help, on aluminium frames, composite doors and window sills alike.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking, and access in Dagenham Dock is something to talk through when you book.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What window mastic looks like in Dagenham Dock
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. In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking.
For site and facilities teams at buildings such as St Peter's Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around St Martin's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Common problems we fix in Dagenham Dock
Sills take more water than any other part of a window, and the ends of the sill, where it meets the wall, are where it gets in. Failed sealant there lets rain into the wall or behind the frame.
These are the problems we are asked about most:
- Mastic that has split away from the wall
- Rushed sealant from a window installation
- Old mastic that has gone black or come away
- Whistling draughts around closed windows
Dagenham Dock is in London, so parking needs planning: let us know about parking bays, permits or a driveway.
Questions to ask before booking

Your questions about window mastic in Dagenham Dock
Is parking an issue for window mastic in Dagenham Dock?
Parking in Dagenham Dock, as in most of London, takes a little planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you work for landlords with property near Dagenham Dock station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
How much does window mastic cost in Dagenham Dock?
It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or send us an email with a short description of the job.
Can you seal the gap between the frame and the plaster indoors?
Yes. Draughts often come through the inside gap too, so it can be worth sealing both.
Do you hold any approvals?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Can you do upstairs windows?
Yes, as long as they can be reached safely. Tell us about access when you get in touch and we will plan for it.
Do you remove the old sealant?
Yes. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What do you put in the joint?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
How the job changes by surface
Aluminium frames
Coated aluminium needs a compatible sealant. We use a neutral-cure product.
Patio & French doors
Heavy door frames can move more than windows. A flexible sealant copes with that, where a rigid one would crack.

- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.
- We apply a weatherproof sealant to match the frame and tool it neatly.

What we cannot put right
Before you book, it’s worth knowing the limits:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Damp coming through the wall itself rather than the frame joint
- A frame that has rotted at the joint
If you’re not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer.
Where we work in Dagenham Dock

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
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.
Looking after it afterwards
Looking after new joints is easy:
- Don’t use solvent cleaners on the joint
- Walk round the house once a year and look at the joints
- Do not aim a pressure washer at the joints
- Keep paint and stain on wooden frames in good order
Check the drainage slots in the frames are not blocked, so water can run away instead of sitting against the joint.
Leaks normally show up in wet, windy weather, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.
