Window & door mastic in Sturry, Kent
We cover Sturry for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly and a one-year guarantee.
- Leaking joints at the ends of sills
- Draughts coming in around windows and doors
- Untidy mastic left by window fitters
DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
How we handle window mastic in Sturry
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so we fit backing rod to set the right depth. That way the new bead bonds to the frame and the wall only. If you are dealing with draughty joints inside around the window and cracked sealant at the sill ends, we can help.
Homes around Sturry range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How the job changes by surface
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. It comes out, deep gaps get backing rod and the joint is resealed.
Window sills
Masonry sills can have joints where water gets in, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.
How the visit works
All our tools and materials come with us in the van, so there’s nothing for you to buy. After a quick look at the joints together, we protect the area and start. Most jobs take a morning for a couple of windows and a door. A visit to Sturry is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, we confirm safe access to each frame.
- 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.
Getting ready for the visit
- Clear items away from the joints we are working on
- Where the joints are inside, avoid wetting them before we arrive
- For business premises, tell us about site rules or sign-in

Window mastic in Sturry: local notes
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.
Managing a site like Sturry Church of England Primary School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Nicholas' Church, the joint between an old wall and a newer frame is normally the first place rain gets in. Letting a property close to Sturry station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Why act early in Sturry
Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Homes in smaller places like Sturry can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. We will give you a clear price for the lot.

When it isn’t the sealant
In fairness, there are a few things sealant won’t fix:
- Misting between the panes of a double-glazed unit (that needs a new unit)
- Rotten timber, which needs a joiner first
- Worn gaskets, brush seals or a door that has dropped
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before you book.

Looking after it afterwards
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Check the mastic once a year
- Clear any debris from frame drain holes
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
Keep sill grooves and drainage slots clear, so water can run away instead of sitting against the joint.
A failed joint lets water into the wall a little at a time. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.
