What we’re called out for in Ashley
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
If you can see any of these, it’s time to have the joints looked at:
- Crumbling sand mastic round a window
- Cement or filler used on old window joints that has cracked
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
If you let a flat or house near Mottisfont & Dunbridge station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

- How the surfaces are prepared before sealing

Sand mastic in Ashley
A silicone bead around a sash window can look out of place and doesn’t suit the building. Sand mastic is the traditional choice and we can swap the silicone for it. Common call-outs are for tired mastic found when preparing windows for paint and old sand mastic that has cracked, crumbled or fallen out, on period & listed homes, timber door frames and stone surrounds.
Homes in small places like Ashley often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

Common questions in Ashley
Is Ashley in your area for sand mastic?
Yes. Our work covers London and the South East, and Ashley is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we will send you a clear quote.
Do you cover smaller places like Ashley?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
What do you put in the joint?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference.
Will you leave a mess?
Not at all. The area is protected while we work and cleaned up afterwards.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
What should I tell you?
Just the basics: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or send us an email.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.

What else we do in Ashley
DIY sealant or a professional job?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
What happens if it’s left?
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. In a small place like Ashley, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first.

Frames and glazing around Ashley
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Mottisfont Abbey (about 4.3 miles south-west) nearby, there’s older building stock in the area around Ashley as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For an older house near a landmark such as St Mary's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
