DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
When something else is needed
Some problems need a builder, plumber or other trade rather than us:
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
- Rotten timber, which needs a joiner first
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Frames and glazing around Brick End
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Horham Hall (about 2.4 miles north-east) are a reminder that the area around Brick End has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
In the older streets around Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Leave it or put it right?
The work is quick compared with the damage it prevents: it takes a few hours for a handful of frames, longer for a whole house. Wait for damp to appear and there may be plaster and decorating to sort out too. Older cottages and farmhouses around Brick End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Doing several joints on one visit is generally more efficient than separate visits. We will give you a clear quote for the lot.

When to call us in Brick End
Water runs down the glass onto the sill, 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.
If you can see any of these, it’s time to have the joints looked at:
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
- Mastic that is falling out in pieces
- Whistling draughts around closed windows
Letting a property close to Stansted Airport station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Does someone need to be in?
That depends on where the joints are. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
How long will my window job take?
It depends on access, the old mastic and the size of the frames. You will know the timing when we quote.
Do you seal inside as well as outside?
Yes. Plenty of draughts come through the inside joint as well as the outside, so it can be worth sealing both.
Do you have sealant for grey or black windows?
Yes. White, brown, anthracite grey, black and clear sealants are all available.
Will you leave a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
What should I tell you?

What the job involves on each surface
Patio & French doors
Patio and French doors have the longest joints on most houses. Most leaks start at the bottom corners, so they get particular care.
Timber windows & doors
On period timber windows, traditional sand mastic is sometimes the better choice. We can talk through the options.
What happens on the day
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of frames, longer for a whole house. In a small place like Brick End, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each frame is looked over and we agree which ones need resealing.
- We remove the old mastic and clean the frame edge and wall.
- Deep gaps get closed-cell backing rod to set the depth.
- A flexible exterior sealant is applied in a colour to suit the frame.
- Every joint is tooled smooth and checked before we leave.
Getting ready for the visit
