Sand mastic for homes and businesses in Bar End
Sand mastic doesn’t last for ever and gaps open up round the frame. We rake it out and renew it and tidies the surround. If you have failed mastic on an exposed elevation and draughty sash windows at the surround, we can put it right.
In a village or hamlet like Bar End, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, so the sealant has to be chosen to suit the building.
Every job comes with a one-year guarantee.

Questions from Bar End
Is Bar End in your area for sand mastic?
Yes. We work across London and the South East, and Bar End is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear quote.
Can you help a landlord with a rental near Winchester station?
Yes, rental work is part of what we do. You can call 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Does someone need to be in?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
How long will you be here?
Typically it takes a few hours for a single window, longer for several. Bigger jobs take longer, and we’ll tell you how long to expect.
How long does sand mastic take to harden?
Not right away. The skin forms first, and the full set comes later, and we will tell you what to expect.
Is it worth trying it myself?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Can I add another job to the visit?
Yes. Several rooms, windows or areas can go on one quote.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Surface by surface
Brick reveals
Sand mastic is also used where timber frames meet brick. It gives a traditional finish.
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
How we quote for sand mastic
There’s no set price list. The quote depends on:
- How many rooms, windows or areas are involved

It all starts with a short chat. Tell us what’s wrong, where it is and how much there is. Whenever you’re ready, call 0345 464 0079 or email us.
Frames and glazing around Bar End

Letting a property close to Winchester station? Then any sash windows need sound mastic to keep draughts and rain out. For site and facilities teams at buildings such as All Saints Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Damaged stone surrounds
- Decayed frames that need repair
- Broken panes
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.
Surfaces we seal
- Sash and case windows
- Brick reveals
- Period & listed homes
- Timber door frames
- Tenement windows
- Stone surrounds
