Sand mastic for homes and businesses in Aldermaston Wharf
A silicone bead around a sash window can look out of place and is not always the right material. Sand mastic is the traditional choice and we can swap the silicone for it. Typical jobs include tired mastic found when preparing windows for paint and crumbling sand mastic round a window, on timber door frames, period & listed homes and sash and case windows.
Around Aldermaston Wharf, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Take care around the mastic when scraping paint
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
- Ask us before painting near the mastic
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger as more mastic falls out.
Questions from Aldermaston Wharf

Yes. We work for letting agents and landlords as well as householders, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Is Aldermaston Wharf within the area you cover?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Can I paint the new mastic?
Traditional guidance is not to paint over sand mastic. If you’re redecorating the window, ask us first and we will talk you through it.
How long does the job take?
A typical job takes a few hours for a single window, longer for several, including the preparation. We’ll confirm how long when we quote.
Will you leave a mess?
No. We protect the surfaces around the joints, and we tidy up before we go.
Is it worth trying it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
Do you have insurance?
Yes. We are fully insured.
How long does sand mastic take to harden?
It takes a while. It skins first and hardens fully later, and we’ll tell you what to expect.
How it works
At the end, we look at the finished work together. The visit itself normally takes anything from a few hours to a full day, depending on how many windows, depending on the size of the job. Somewhere as small as Aldermaston Wharf, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Mention any sign-in or site rules at work premises
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed

Related advice
What happens if it’s left?
Draughts round a sash window are not always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Older cottages and farmhouses around Aldermaston Wharf can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
If in doubt, call 0345 464 0079 or email us and we will say what we think before booking.

What sand mastic looks like in Aldermaston Wharf
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
