Sand mastic in Margery, done properly
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it and tidies the surround. We are often asked to deal with old sand mastic that has cracked, crumbled or fallen out and patchy fillers round a sash window, across period & listed homes, sash and case windows and stone surrounds.
Around Margery, 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.
Each job carries a 12-month guarantee.

What we cannot put right
Sealant isn’t the answer to every problem, and we’ll tell you before we start. Sealant will not put right:
- Sashes that need overhauling
- Cracked or broken glass
- Whether work needs listed building consent
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
Joints and surfaces we work on
- Period & listed homes
- Sash and case windows
- Brick reveals
- Stone surrounds
- Tenement windows
- Timber door frames
Why deal with it now?
Not every filler suits an old window surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Where a wall is exposed, as many are in small places like Margery, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. The price is agreed before we begin.
Why Margery clients choose us
- Neat joints and a tidy finish
- Anti-fungal sanitary silicone in wet areas

Questions from Margery
Can you help a landlord with a rental near Reigate station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we will send you a clear quote.
Do you cover smaller places like Margery?
Yes. Margery is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
How much does sand mastic cost in Margery?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Should I check with the council before work on a listed or conservation-area home?
It’s best to ask your local planning authority first. Like-for-like sand mastic is often the preferred finish, but they decide.
Can new sealant go over the old?
No, and we never do. It may look fine at first, but the new bead soon lifts. The old sealant has to come out completely.
Can I choose the sealant colour?
We help you choose a colour that suits, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you hold any approvals?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.
Where do you work from?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What happens on the day
Every visit runs the same way: we check the joints, protect the area around them, do the work and tidy away. It normally takes a few hours for a single window, longer for several. For a village or hamlet like Margery, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Keep children and pets away from the work area
- Mention any leaks or damp you’ve noticed
- Try not to wet indoor joints just before the visit

Related advice
What the job involves on each surface
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
Timber door frames
Doors face weather and wear and the mastic can crack early. We rake it out and renew it.
DIY versus a professional finish
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Windows and doors in Margery
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of Jesus Christ and the Wisdom of God, the joint between an old wall and a newer frame is generally the first place rain gets in. Managing a site like Kingswood Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. If you let a flat or house near Reigate station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
