Window mastic for homes and businesses in Churt
The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. Common call-outs are for untidy mastic left by window fitters and a bead that doesn’t match the frame, on uPVC windows, window sills and aluminium frames.
In a village or hamlet like Churt, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

How it works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Churt, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each window and door with you.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- On commercial sites, let us know about site rules
- Tell us about any water getting in

Advice
Common problems we fix in Churt
Timber windows bring their own problems. Old mastic gets painted over and cracks under the paint, and the wood moves with damp as well as heat.
Look out for these signs:
- Gaps where the sill meets the wall
- Gaps left after new windows were fitted
- Hard, cracked sealant around windows
- Damp patches on the reveal after heavy rain
If you look after a building such as St John's CofE Aided Infant School, its window and door frames need their mastic kept sound, just like a home’s.
Questions to ask before you book
- Is VAT in the price?
- How the surfaces are prepared before sealing
- Whether you can choose the colour
- Whether they seal over old material or remove it
What window mastic looks like in Churt
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Haslemere station, renewing tired window mastic between tenants heads off draught and damp complaints. For an older house near a landmark such as St John the Evangelist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Surface by 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.
uPVC windows
Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
Aftercare tips
Aftercare is simple:
- Air rooms to keep condensation down around windows
- Clear any debris from frame drain holes
- Keep timber frames painted
- Avoid harsh chemicals near the mastic
Most silicone sealants won’t take paint, so mention any painting plans before we start. We can use a paintable sealant where that matters.
On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

Will you come out to Churt?
Yes. Churt is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can I do it myself?

Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.

Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Why it’s worth doing now in Churt
Once mastic fails, rain can get between the frame and the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Churt, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
What sealant work can’t fix
In fairness, some problems need a different trade:
- Broken hinges, locks or handles
- Condensation trapped between the panes
- A door that needs adjusting, rehanging or new seals
Not sure which it is? You can call 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
