Window mastic in Magdalen Laver, 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 deep gaps get backing rod first. The sealant then grips the two sides it should. Typical jobs include mastic that’s falling out in pieces and hard, cracked sealant around windows, across composite doors, patio & French doors and aluminium frames.
Somewhere as small as Magdalen Laver, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
We stand behind the work with a 12-month guarantee, so you’re covered after we’ve gone.

How it works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the job takes most of a day for a typical house, less for a few frames in most cases. For a village or hamlet like Magdalen Laver, 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 how each frame can be reached safely.
- Old, cracked mastic is removed completely.
- The surfaces are cleaned and left dry, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- We tool the joint so water runs off, then clear up.
Before we arrive
- On commercial sites, let us know about site rules
- Keep pets and children clear of the area while we work
- Mention any leaks or damp you’ve noticed

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What happens if it’s left?
Running fresh sealant over the old joint is tempting, but it will not grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Older cottages and farmhouses around Magdalen Laver can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Paint up to the joint, not over it
- Repaint timber before it’s bare
- Clear any debris from frame drain holes
- Wipe condensation off the frames
Silicone can’t normally be painted, so mention any painting plans before work begins. There are paintable sealants for joints that need it.
Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. A new joint closes it up.

Frames and glazing around Magdalen Laver
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Parish Church of St Mary Magdalen, the joint between an old wall and a newer frame is normally the first place rain gets in.

When to call us in Magdalen Laver
Mastic ages in the weather. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.
If you can see any of these, it’s time to have the joints looked at:
- White mastic on grey or black frames
- Cracked internal joints between frame and plaster
- Draughts coming in around windows and doors
- Gaps left after new windows were fitted
For landlords with property near Harlow Mill station, renewing tired window mastic between tenants heads off draught and damp complaints.
