The price is agreed before any work begins. It takes into account:
- The product the joint needs
- How much there is to do
- Any mould that needs treating
- Working hours on commercial sites
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are unsure, call 0345 464 0079 or email us for an honest opinion and a quote.

Sand mastic for homes and businesses in Coalhill
Across Coalhill, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. We work on tenement windows, period & listed homes and sash and case windows, and people most often call us about failed mastic on an exposed elevation and old sand mastic that has cracked, crumbled or fallen out.
Somewhere as small as Coalhill, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes as standard.

Should I try it myself first?
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, then guaranteed for a year.
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
- Keep sills and gutters clear so water drains away
- Sort the mastic before the decorators arrive
Leave the new mastic unpainted, which is the traditional advice. If you’re redecorating, ask us first.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What sand mastic looks like in Coalhill
Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Danbury Place (about 4.5 miles north) are a reminder that the area around Coalhill has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Battlesbridge station change hands often, and older sash windows in a rental need their mastic kept sound to keep the weather out. If you live in an older home near Church of St Peter, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Common questions in Coalhill
Do you work for landlords with property near Battlesbridge station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Can you do sand mastic in Coalhill?
Yes, Coalhill is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or drop us an email with a few details of the job, and we’ll give you a clear price.
Are you an approved applicator?
Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
What’s sand mastic made of?
Sand mastic is a traditional material for pointing round windows and doors. It’s made with sand and a linseed-oil-based binder.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
How the job changes by surface
Timber door frames
Doors face weather and wear and the mastic can crack early. It’s renewed by hand.
Sash and case windows
Most of our sand mastic work is on sash windows. We renew the mastic round each box.
Leave it or put it right?
If you’re redecorating, renew the mastic first. Paint over cracked mastic won’t stop the gaps and traditional guidance is to leave the new mastic unpainted. Around Coalhill, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
No two jobs are quite the same, so we quote each one individually. Size, access and the product the joint needs all play a part.

The process
On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours per window, depending on the condition of the joints. Somewhere as small as Coalhill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- 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.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Let us know about parking restrictions
- Let us know if you’ve seen damp or leaks
- Mention if the joints have been sealed before
