Sand mastic for homes and businesses in Broad Green
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. We work on stone surrounds, brick reveals and sash and case windows, and people most often call us about gaps round a timber door in stone or brick and a silicone bead on a sash window that spoils the look.
In a village or hamlet like Broad Green, 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.
Each job carries a 12-month guarantee.

What we are called out for in Broad Green
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
The most common problems we see are:
- Old cement repairs round a window that have failed
- Draughts and rain around sash boxes
- Gaps where the frame meets the masonry
- Silicone on a period window that looks wrong
If you live in an older home near Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Broad Green: your questions answered
Do you cover smaller places like Broad Green?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near Marks Tey station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Can I choose the sealant colour?
Generally, yes. White, clear and grey are common, and other colours are available for many products, and we’ll agree it with you first.
Are you ARBOMaster approved?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can new sealant go over the old?
No. Fresh sealant doesn’t stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We will tell you what we’re using and why.
Do I need to be at home?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
Do you do commercial work?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.
What happens on the day
You don’t need to clear the whole room or building before we come, only the area right around the joints. We protect the rest, and the job takes a few hours for a single window, longer for several in most cases. Somewhere as small as Broad Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts
- Try not to wet indoor joints just before the visit

Related advice
For landlords and businesses
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 that we can handle for you.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Surface by surface
Timber door frames
A neat sand mastic joint round a front door suits a period home.
Period and listed homes
On a listed home or in a conservation area, the right material matters. Like-for-like sand mastic is generally favoured.
Why it’s worth doing now in Broad Green
Not every filler suits an old window surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. Around Broad Green, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

DIY sealant or a professional job?
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
What sand mastic looks like in Broad Green
With historic houses such as Layer Marney Tower (about 4.6 miles south-east) nearby, there’s older building stock in the area around Broad Green as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For landlords with property near Marks Tey station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Honywood Community Science School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
