Sand mastic for sash & case windows in Ashfield, Hampshire
Our applicators work in Ashfield on traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and a one-year guarantee.
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
- Draughty sash windows at the surround
DIY sealant or a professional job?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Sand mastic in Ashfield, done properly
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you have open joints round the window box and old sand mastic that has cracked, crumbled or fallen out, we can put it right, on sash and case windows, timber door frames and stone surrounds alike.
Mastic can only go onto a dry, clean joint, so window work in Ashfield is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
Each job carries a 12-month guarantee, whatever its size.

Frames and glazing around Ashfield
Ashfield is within about 3 miles of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Oasis Academy Lord's Hill, its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Romsey station, older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Boniface, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Aftercare tips
A little care helps the new joints last. Our advice:
- Inspect the joints round the windows every year or so
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
- Find out about consent before window work on a listed home
Avoid painting over the new mastic, as traditional guidance advises. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Surface by surface
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
Stone surrounds
Stone openings are rarely perfectly straight, so the gap is not the same all the way round. Sand mastic is shaped by hand to suit.
When something else is needed
We’d rather tell you now than do work that will not last, so here’s what sealant can’t put right:
- Planning or listed building consent (your local planning authority decides)
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
