Sand mastic in Baulking, done properly
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We are often asked to deal with cement or filler used on old window joints that has cracked and gaps where the frame meets the masonry, on period & listed homes, stone surrounds and tenement windows.
Homes in small places like Baulking often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Different surfaces, different methods
Tenement and terrace windows
In shared buildings, the windows may be part of a wider repair so it’s worth checking responsibilities.
Brick reveals
Brick reveals round timber windows are often pointed with sand mastic. It gives a traditional finish.
The process
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for a single window, longer for several. In a small place like Baulking, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Keep pets and children clear of the area while we work
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

Advice
Do you need sand mastic in Baulking?
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
If you can see any of these, it’s time to have the joints looked at:
- Mastic dropping out of the joint
- Draughts and rain around sash boxes
- Silicone on a period window that looks wrong
- Gaps round a timber door in stone or brick
Around Baulking, as everywhere, sand mastic is only as good as the preparation behind it.
Before booking anyone
- When the joint can take water or movement
- Whether they seal over old material or remove it
- What happens if the job turns out different
- How much experience the applicator has

What else we do in Baulking
Why it’s worth doing now in Baulking
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Around Baulking, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs. Ask us for a quote and we will go through it with you.

Frames and glazing around Baulking
Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Baulking: your questions answered
Will you come out to Baulking?
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.
Is sand mastic in Baulking guaranteed?
Every job comes with our 12-month guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Will it make a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Can new sealant go over the old?
No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.
I’m a tenant. Can you help?
We can work for tenants, landlords or agents. Just make sure your landlord agrees.
Do you remove the old sealant?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
What do you need from me for a quote?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Can I do it myself?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. If it doesn’t work out, we can redo it.
What sealant work can’t fix
A few problems are outside what sealant work can do:
- Masonry that needs repairing
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
Not sure which it is? You can phone 0345 464 0079 or drop us an email and we’ll tell you honestly before booking.

- The type of sealant required

- If someone has resealed it before
- Whether it’s a home or a business
- The problem you’ve noticed
