What affects the quote in Oliver's Battery
There’s no set price list, because jobs vary so much. The quote depends on:
- The number of rooms or windows
- Which sealant suits the joint
- Mould in or behind the old joints
- Any working-time requirements on site
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part.

Sand mastic for homes and businesses in Oliver's Battery
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Common call-outs are for draughts and rain around sash boxes and mastic dropping out of the joint, on stone surrounds, period & listed homes and brick reveals.
Mastic can only go onto a dry, clean joint, so window work in Oliver's Battery is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
You are covered for a year from the day we finish. If anything is not right with it, phone 0345 464 0079 or drop us an email.

Your questions about sand mastic in Oliver's Battery
Is Oliver's Battery in your area for sand mastic?
Yes, Oliver's Battery is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job.
Will you come out to Oliver's Battery?
Yes. Oliver's Battery is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
When will the new mastic be hard?
It forms a skin fairly soon and it hardens fully over a longer time. Timing depends on the weather and the joint.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
What guarantee comes with the work?
There’s a 12-month guarantee on every job.
How long will you be here?
As a guide, most jobs take a few hours for a single window, longer for several. Bigger jobs take longer.
Are you fully insured?
Yes. We’re fully insured.
Surface by surface
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Aftercare tips
To keep the joints looking good and working properly:
- Renew mastic before redecorating the windows
- Find out about consent before window work on a listed home
- Do not paint over the new mastic
- Have rotten timber repaired before new mastic goes in
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
For landlords and businesses
From a single let to a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
Can I do it myself?
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What happens on the day
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere as small as Oliver's Battery, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Mention if the joints have been sealed before
- Keep pets and children clear of the area while we work
- Clear the area around the work

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.
