Window mastic in Shorthampton
Some gaps around frames are far deeper than they look. Packing it solid with sealant gives a joint that cannot flex, so deep gaps get backing rod first. The sealant then grips the two sides it should. If you’re dealing with hard, cracked sealant around windows and damp patches on the reveal after heavy rain, we can put it right.
Around Shorthampton, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

When to call us in Shorthampton
Some failures date back to when the windows were fitted. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, so it comes away long before its time.
Keep an eye out for these signs:
- Cracked internal joints between frame and plaster
- Rushed sealant from a window installation
- Whistling draughts around closed windows
- Leaking joints at the ends of sills
For landlords with property near Charlbury station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Leave it or put it right?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Where a wall is exposed, as many are in small places like Shorthampton, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email and we will give you an honest view and a quote.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can be quoted together.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Make sure the drainage slots aren’t blocked
- Do not paint over the silicone
- Don’t use solvent cleaners on the joint
- Wash the frames with mild soapy water
Check the drainage slots in the frames aren’t blocked, so water can run away instead of sitting against the joint.
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.

Some sealants have a smell while they cure, but it fades. Ventilation helps.
