South Street questions
I let a flat near Meopham station. Can you help?
Yes, we work for letting agents and landlords. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll give you a clear price.
Do you cover smaller places like South Street?
Yes, we do. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Will there be a smell?
Sometimes, a little. Any smell clears as the sealant cures.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We’ll tell you what we are using and why.
Are you insured?
Yes. We’re fully insured for every job we do.
Can new sealant go over the old?
No, because it fails. The old sealant always comes out first, so the new joint bonds to clean surfaces.
What does sand mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.
Sand mastic in South Street, done properly
Silicone on a period window often looks wrong and does not suit the building. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. Typical jobs include modern sealant on a period surround and old cement repairs round a window that have failed, across period & listed homes, sash and case windows and tenement windows.
In a village or hamlet like South Street, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

Do you need sand mastic in South Street?
Over the years, sand mastic weathers. It hardens, cracks and starts to come away from the frame or the masonry.
Keep an eye out for any of the following:
- Draughts and rain around sash boxes
- Gaps where the frame meets the masonry
- Old cement repairs round a window that have failed
- Gaps round a timber door in stone or brick
Schools such as Culverstone Green Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Aftercare tips
No joint lasts for ever, but care makes a real difference. A few tips:
- Do not paint over the new mastic
- Make sure water runs off the sill
- Get any rot dealt with first
- Check with your local planning authority if your home is listed
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
How the visit works
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. Somewhere as small as South Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Mention any tricky access
Getting a quote

Sand mastic in South Street: local notes
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. With historic houses such as Cobham College (about 3.3 miles north-east) nearby, there’s older building stock in the area around South Street as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Rented homes near Meopham station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. Cobham College, about 3.3 miles north-east, is one of the historic houses in the wider area around South Street.

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
