Window mastic in Over Wallop, done properly
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. The sealant then grips the two sides it should. If you have a bead that doesn’t match the frame and hard, cracked sealant around windows, we can help, whatever the surface.
Somewhere as small as Over Wallop, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
Big or small, you get the same one-year guarantee in Over Wallop and across Hampshire.

Why it’s worth doing now in Over Wallop
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. A reseal is a much smaller job. Older cottages and farmhouses around Over Wallop can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Window mastic in Over Wallop: local notes
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.
In the older streets around Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Wallop Primary School? Then its window and door frames need their mastic kept sound, just like a home’s.

Questions from Over Wallop
Will you come out to Over Wallop?
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.
Can you do window mastic in Over Wallop?
Yes. We work across London and the South East, and Over Wallop is part of that. Just call 0345 464 0079 or email us with a few details of the job.
Do I need to be at home?
It depends on the job. Inside work needs someone to give us access, and for outside work we will agree access with you when we book.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
When is the sealant fully cured?
It depends on the product and the temperature. We tell you how long to leave it before we go.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done.
Can new window sealant be painted?
That depends on the product. Silicone is not paintable, but some hybrid sealants are. Tell us if you are decorating and we will choose accordingly.
Can resealing stop a draught around my window?
Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.
Aftercare tips
Aftercare is simple:
- Look round the frames every year or so
- Use gentle cleaners on frames and sealant
- Keep paint off silicone joints
- Make sure the drainage slots are not blocked
Wipe the frames with soapy water when you clean the windows, and keep solvents and harsh chemicals off the joint.
A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.
What the job involves on each surface
Patio & French doors
Not every patio door leak is a mastic problem: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.
Window sills
The end joints of a sill tend to fail before the rest. A tight seal at each end keeps rain out of the wall.
Landlords, agents and businesses in Over Wallop
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
We work for landlords and agents as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.
How the visit works
There’s no need to move everything out, only the area right around the joints. We protect the rest, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere as small as Over Wallop, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each frame and agree which ones need doing.
- We remove the old mastic and clean the frame and the wall.
- Deep gaps are filled with backing rod to set the depth.

What we’re called out for in Over Wallop
Every frame moves through the day. Sun on a frame makes it expand, and it contracts again overnight, while the masonry beside it stays put. A sealant that cannot keep up eventually tears.
Common reasons people contact us are:
- Untidy mastic left by window fitters
- Damp patches on the reveal after heavy rain
- Gaps where the sill meets the wall
- Old mastic that has gone black or come away
Rented homes near Grateley station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.
