Old Ford Window Mastic
Professional window mastic in and around Old Ford, with every bit of old sealant taken out first.
- Draughty joints inside around the window
- Mastic that has split away from the wall
- Leaking joints at the ends of sills
When to call us in Old Ford
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.
Most people get in touch after spotting something like this:
- Water coming in at the bottom corners of a door
- Cracked or shrunken mastic around the frame
- Gaps between the frame and the inside reveal
- Cracked sealant at the sill ends
In the older streets around St Paul Old Ford, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What window mastic looks like in Old Ford
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
As a London address, Old Ford can be tricky for parking: let us know about parking bays, permits or a driveway. For site and facilities teams at buildings such as Mulberry UTC, larger buildings have plenty of frames, and the mastic around each one ages.

Keeping the joints in good condition
Looking after new joints is easy:
- Check the mastic once a year
- Do not paint over the silicone
- Do not aim a pressure washer at the joints
- Wipe condensation off the frames
Keep the new mastic undisturbed while it cures, for as long as we advise. Do not point a pressure washer at the joints.
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.
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a morning for a couple of windows and a door. In a London area like Old Ford, the main things to plan are parking and access: let us know about parking, the floor we will be working on and any lift or shared entrance.
- First, we go round the frames with you and agree the list.
- The old mastic is cut out and scraped back to clean surfaces.
- 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.
- We tool each bead neatly and check every joint is closed.
How to prepare
- Keep children and pets away from the work area
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Leave it or put it right?
If you’re painting or rendering, reseal at the same time. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- A sash or casement that will not close properly

Old Ford questions
Is parking an issue for window mastic in Old Ford?
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.
Do you cover Old Ford for window mastic?
Yes. Our work covers London and the South East, and Old Ford is part of that. You can call 0345 464 0079 or drop us an email and let us know what needs doing.
How much does window mastic cost in Old Ford?
We do not publish prices, because the cost depends on the job: its size, the old material, access and the product needed. We agree the price before any work begins.
Will there be a smell?
It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we’ll explain our choice.
Are you insured?
Yes. We’re fully insured.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Can I do it myself?
Sometimes. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Different surfaces, different methods
Aluminium frames
Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. We use a neutral-cure product.
uPVC windows
uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.
What affects the cost of window mastic
For a quick quote, just ask. What matters most is:
- How easy the joints are to reach
- The number of rooms or windows
- The number and length of the joints
- How much old sealant there is and how hard it is to remove
The cost reflects the work involved, not a rough estimate. That’s why we ask about the job first and agree the price before starting.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the job is, and your postcode
- Access, such as stairs, a lift or height
- Whether it’s a home or a business
- What the problem is, such as mould, gaps, leaks or cracking
