Window mastic in Hampstead Norreys, done properly
There are two joints on most windows. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. We seal one or both, depending on what’s needed. If you have gaps where the sill meets the wall and mastic that’s falling out in pieces, we can help, on window sills, timber windows & doors and aluminium frames alike.
Around Hampstead Norreys, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How the visit works
On the day, we start by going over the job with you. We protect the surfaces around the joints before we start. Most jobs take most of a day for a typical house, less for a few frames. For a village or hamlet like Hampstead Norreys, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
- Every joint is tooled smooth and checked before we leave.
Before we arrive
- Tell us about any water getting in
- Mention any tricky access
- Where the joints are inside, avoid wetting them before we arrive

Common problems we fix in Hampstead Norreys
A lot of older mastic was never designed to stay flexible. Once it has hardened, the frame’s movement tears it from the wall, and a gap opens along one edge.
People usually contact us when they notice something like this:
- Black, perished sealant on frames
- Gaps where the sill meets the wall
- Untidy mastic left by window fitters
- Hard, cracked sealant around windows
For site and facilities teams at buildings such as Hampstead Norreys C.E. Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
What the job involves on each surface
Patio & French doors
The joints around patio doors run a long way, top, sides and threshold. Most leaks start at the bottom corners, so we pay close attention there.
Window sills
Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
Windows and doors in Hampstead Norreys
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.
Homes close to Church of St Mary include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Why act early in Hampstead Norreys
The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Leave it until water is coming in and you may need plastering and decorating as well. Around Hampstead Norreys, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Commercial jobs are quoted on the same basis as homes: how much there is to do, how we reach it and what it needs. Call for a quick quote and we will explain what it covers.

What sealant work cannot fix
To be straight with you, some problems need a different trade:

- Penetrating damp from a failed cavity tray or render
- Draughts through the window seals rather than the frame
