Frames and glazing around East Ham
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St Bartholomew's Church, the joint between an old wall and a newer frame is usually the first place rain gets in. East Ham is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. For landlords with property near Barking station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
East Ham is about 5 miles south-east of Walthamstow, in Greater London. Across the E6 area, we cover window mastic for homes and businesses. 764 places in Greater London are on our list, large and small. We also work in London, about 7 miles from East Ham.
Every address in E6, IG11, E13 and E12 is within our area for window mastic, from the main roads to the quietest streets. Window mastic is available to properties on High Street South, Market Street and High Street North and the roads around them. East Ham is on the A13 and A117, which makes it straightforward to reach.

For rail, the closest station is Barking station, roughly 1.3 miles north-east.

The countryside around East Ham includes Ripple Nature Reserve and Hollow Pond.
Window mastic in East Ham, done properly
Some gaps around frames are far deeper than they look. Filling it with sealant alone leaves a joint that cannot move properly, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you have cracked sealant at the sill ends and hard, cracked sealant around windows, we can help.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.
Your job is guaranteed for a year, as with all our work.

When something else is needed
It helps to know what we can’t do:
- Faulty window hardware
- A frame that has rotted at the joint
- Misting between the panes of a double-glazed unit (that needs a new unit)
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think.
Surfaces we seal
- uPVC windows
- Aluminium frames
- Timber windows & doors
- Composite doors
- Patio & French doors
- Window sills
What the job involves on each surface
Window sills
Where a sill meets brick or render, the ends often crack first. We reseal them so rain can’t run into the wall.
Patio & French doors
Door frames take knocks and movement every time the doors are used. A flexible sealant copes with that, where a rigid one would crack.
What affects the cost of window mastic
Some jobs are bigger than they look, and some smaller. The main factors:
- When we can work, for business premises
- The old material and how stubborn it is
- Any mould that needs treating
- The number and length of the joints
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
Asking for a quote
You do not need to know the technical terms. It helps if you can tell us:
- What the problem is, such as mould, gaps, leaks or cracking
- How many joints, rooms or windows are involved
- Any access issues, like height or stairs
- Any previous sealing or DIY work
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we’ll talk you through what we’d do. When it suits you, call 0345 464 0079 or send us an email.
What happens if it’s left?
Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. Resealing now is a small job by comparison. In a flat in East Ham, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting. If you’re unsure, ring 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

How the visit works
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from an hour or two to a full day, depending on how many frames there are. In East Ham, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Where gaps are deep, backing rod goes in first.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Every joint is checked before we leave.
How to prepare
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in
- Let us know if you’ve seen damp or leaks
