Window & door mastic in Greenstead Green, Essex
Professional window mastic in and around Greenstead Green, with every bit of old sealant taken out first.
- Draughty joints inside around the window
- Gaps where the sill meets the wall
- Rain getting in at the frame or under the sill
Should I try it myself first?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Keeping the joints in good condition
Looking after new joints is easy:
- Look round the frames every year or so
- Clean frames with a soft cloth and soapy water
- Keep paint off silicone joints
- Clear any debris from frame drain holes
Timber frames need their paint kept up, since wood that gets wet swells and shrinks more. Keep paint off the silicone itself.
Look out for the warning signs: split or missing mastic, gaps, damp patches inside or black mould on the reveal. If you notice one, it’s time to get the joint looked at.
What we are called out for in Greenstead Green
Frames are never completely still. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. If the sealant can’t stretch, it splits.
If you can see any of these, it’s time to have the joints looked at:
- Damp patches on the reveal after heavy rain
- Cold air getting in at the frame edge
- Old mastic that has gone black or come away
- Cracked sealant at the sill ends
If you let a flat or house near Chappel & Wakes Colne station, renewing tired window mastic between tenants heads off draught and damp complaints.
Questions to ask before booking

Why it’s worth doing now in Greenstead Green
Resealing frames is a short job: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. In a small place like Greenstead Green, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.

Honest limits
In fairness, there are a few things sealant won’t fix:
- Condensation trapped between the panes
- Worn gaskets, brush seals or a door that has dropped
- Damp problems in the wall away from the window

What happens on the day
There’s no need to move everything out before we come, only the area right around the joints. Everything nearby is protected, and the work takes most of a day for a typical house, less for a few frames for a typical job. In a small place like Greenstead Green, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First we look at every frame and agree the list.
- Next the failed sealant is cut away and the joint cleaned.
- Where gaps are deep, backing rod goes in first.
- New exterior sealant goes on in a matching colour and is tooled smooth.
- Finally we tidy up and check each joint.
Before we arrive
- Keep children and pets away from the work area
- Where the joints are inside, avoid wetting them before we arrive
- Tell us about any water getting in

Frames and glazing around Greenstead Green
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For site and facilities teams at buildings such as The Ramsey Academy, the mastic around its windows and doors needs looking after like any other building’s. Homes close to Parish Church of St James include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.
