St. Ebbes Sand Mastic
We cover St. Ebbes for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Old sand mastic that has cracked, crumbled or fallen out
- Weathered mastic on the most exposed windows
- Wind and rain getting in round a sash window
How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Inspect the joints round the windows every year or so
- Plan mastic work ahead of painting
- Do not paint over the new mastic
- Check with your local planning authority if your home is listed
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
How we handle sand mastic in St. Ebbes
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. Typical jobs include patchy fillers round a sash window and draughts and rain around sash boxes, across period & listed homes, brick reveals and sash and case windows.
In smaller places like St. Ebbes, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.
A one-year guarantee comes with the work, just as it does everywhere we cover.

How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It generally takes a few hours per window, depending on the condition of the joints. Parking around St. Ebbes is normally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Preparing for the visit
- Mention any tricky access
- Clear the area around the work
- Try not to wet indoor joints just before the visit

Advice
For landlords and businesses
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

What we’re called out for in St. Ebbes
Paint, silicone or cement used over old mastic causes problems. They do not move with the timber, and they generally need raking out.
The most common problems we see are:
- Draughts and rain around sash boxes
- Weathered mastic on the most exposed windows
- Modern sealant on a period surround
- Open joints round the window box
Homes close to St Ebbe's Church include some older properties, and the joint between an old wall and a newer frame is usually the first place rain gets in.
What your quote should include
- Which sealant they’ll use, and why
- When the joint can take water or movement
- What happens if they find a problem under the old sealant
- How the colour is chosen
St. Ebbes questions

Yes. Our work covers London and the South East, and St. Ebbes is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Will you come out to St. Ebbes?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you match the sealant colour?
Most of the time, yes. We’ll explain which colours are available and agree one before we start.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
When will the new mastic be hard?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator, which is run for the Arbo sealant brand.

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You will get a clear quote before work begins.
Why it’s worth doing now in St. Ebbes
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In an older home around St. Ebbes, damp from a failed joint can get into timber and plaster, and that’s a much bigger job than renewing the sealant.
Rather than a set price list, 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.

What sand mastic looks like in St. Ebbes
The South East is one of the drier parts 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 Holywell Manor (about 0.7 miles north-east) nearby, there’s older building stock in the area around St. Ebbes as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
For site and facilities teams at buildings such as Oxford Media & Business School, larger buildings have plenty of frames, and the mastic around each one ages. For landlords with property near Oxford station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
