About our sand mastic in Holmbury St Mary
We renew sand mastic around sash windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. We work on brick reveals, timber door frames and tenement windows, and people most often call us about wind and rain getting in round a sash window and gaps between timber frames and stone or brick.
Somewhere as small as Holmbury St Mary, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
You’re covered for a year from the day we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

What the job involves on each surface
Stone surrounds
Sand mastic sits naturally against stone. The finish blends with the masonry.
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
What sand mastic looks like in Holmbury St Mary
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Polesden Lacey (about 4.8 miles north) nearby, there’s older building stock in the area around Holmbury St Mary as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to St Mary The Virgins Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in. If you look after a building such as Belmont Prep School, the mastic around its windows and doors needs looking after like any other building’s.

What affects the cost of sand mastic
Jobs vary more than people expect. The main factors:
- When we can work, for business premises
- The product the joint needs
- The old material and how stubborn it is
- How easy the joints are to reach
A failed joint rarely gets cheaper to fix by waiting. If you’re not sure whether it needs doing, call 0345 464 0079 or email us for an honest opinion and a quote.
Asking for a quote
The more you tell us, the more accurate the quote. When you ask for a quote, tell us:
- The problem you’ve noticed
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs
- Roughly how big the job is
If you are in Holmbury St Mary and need sand mastic, call 0345 464 0079 or email us. A short description of the job and where it is helps us quote, and we’ll agree the price before any work begins.
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Do not run silicone over sand mastic
- Check the mastic when you check the paintwork
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.

Your questions about sand mastic in Holmbury St Mary
Will you come out to Holmbury St Mary?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is Holmbury St Mary in your area for sand mastic?
Yes, Holmbury St Mary is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Should I try DIY first?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Can you work on commercial sites?
Yes. We have worked for hotels, offices and other businesses.
Should I use sand mastic or silicone?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
What should I tell you?
Let us know what needs doing and where, with pictures by email if possible. We’ll ask anything else we need to know.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
What we are called out for in Holmbury St Mary
Rain on the window surround works into any crack and pushes it out. Windows facing the weather tend to go first.
It’s worth asking for a quote if you see:
- Mastic that needs renewing before redecorating
- Silicone on a period window that looks wrong
- Old cement repairs round a window that have failed
- Cracked mastic round a front door frame
If you let a flat or house near Gomshall station, any sash windows need sound mastic to keep draughts and rain out.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Honest limits
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
- Planning or listed building consent (your local planning authority decides)
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.
