Window mastic in Balmerlawn, done properly
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. We work on window sills, aluminium frames and timber windows & doors, and people most often call us about water coming in at the bottom corners of a door and rushed sealant from a window installation.
In a village or hamlet like Balmerlawn, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.

How the visit works
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes most of a day for a typical house, less for a few frames. For a village or hamlet like Balmerlawn, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We check each frame and agree which ones need doing.
- The old mastic is cut out and the surfaces cleaned back.
- Deep gaps are filled with backing rod to set the depth.
- A flexible, weatherproof sealant is applied in a colour to suit the frame.
- Finally we tidy up and check each joint.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Mention if the joints have been sealed before
- Mention any tricky access

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Look round the frames every year or so
- Repaint timber before it’s bare
- Ventilate rooms so frames don’t stay wet inside
- Make sure the drainage slots are not blocked
Silicone cannot normally be painted, so if you are planning to paint the frames or walls, tell us beforehand. We can use a paintable sealant where that matters.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Catching it early keeps the fix to a reseal.
Common problems we fix in Balmerlawn
On timber frames, paint and putty build up around the joint. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
If you can see any of these, it’s time to have the joints looked at:
- Cracked or shrunken mastic around the frame
- Rushed sealant from a window installation
- Gaps where the sill meets the wall
- Draughty joints inside around the window
If you look after a building such as Brockenhurst Church of England Primary School, the mastic around its windows and doors needs looking after like any other building’s.
Questions to ask before you book
- What preparation is included
- Are they insured?
- Whether they seal over old material or remove it
- Which colour the sealant will be
Window mastic in Balmerlawn: local notes
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 Beaulieu Palace House (about 4.9 miles east) are a reminder that the area around Balmerlawn has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near Brockenhurst station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Nicholas, the joint between an old wall and a newer frame is generally the first place rain gets in.
