About our sand mastic in Burlings
On many period windows, sand mastic looks right and suits the building. On modern frames we’d normally use a flexible sealant, and we’ll talk through which suits your home. We work on stone surrounds, period & listed homes and timber door frames, and common reasons people get in touch are crumbling sand mastic round a window and patchy fillers round a sash window.
Around Burlings, 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.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

FAQs for Burlings
Do you cover smaller places like Burlings?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
Do you work for landlords with property near Knockholt station?
Yes. We work for landlords and letting agents as well as householders. You can ring 0345 464 0079 or email us with the details for a clear quote.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Do you take out the old sealant first?
Yes. Sealing over the old bead is the commonest cause of early failure, so we never do it.
Which is right for my windows, sand mastic or modern sealant?
We will talk it through with you. Period homes often look best with sand mastic and newer frames suit modern sealant.
Should I try DIY first?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

- Whether there’s mould to deal with
- Working hours on commercial sites
- The type of sealant required
- Whether old sealant or filler has to be cut out
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

The process
There’s no need to move everything out before we come, just the space around the work. Everything nearby is protected, and the job takes a few hours per window, depending on the condition of the joints in most cases. For a village or hamlet like Burlings, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- The mastic is mixed, pressed into the joint by hand and shaped.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us if parking is tricky
- Keep pets and children clear of the area while we work
- Try not to wet indoor joints just before the visit

Windows and doors in Burlings
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Down House (about 2.2 miles north-west) nearby, there’s older building stock in the area around Burlings as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around St Katharine's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Knockholt station, older sash windows in a rental need their mastic kept sound to keep the weather out. Schools such as Charles Darwin School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

What happens if it’s left?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic matches what was there and that can be important for listed homes. Where a wall is exposed, as many are in small places like Burlings, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Leaving a failed joint generally makes the job bigger, not smaller. If you are not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Landlord and commercial work in Burlings
Letting agents and landlords in Burlings can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Aftercare tips
After the cure time, these simple habits help:
- Don’t paint over the new mastic
- Go gently near the mastic when preparing windows
- Inspect the joints round the windows every year or so
- Check with your local planning authority if your home is listed
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
An open joint round the box lets weather through. Left, the gap tends to get bigger.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
