Sand mastic in Aston Tirrold, done properly
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. Common call-outs are for failed mastic on an exposed elevation and cracked mastic round a front door frame, across tenement windows, timber door frames and period & listed homes.
Homes in small places like Aston Tirrold 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.
A 12-month guarantee comes as standard, so you’re covered after we’ve gone.

Windows and doors in Aston Tirrold
With historic houses such as Brightwell Manor (about 3.3 miles north-east) nearby, there’s older building stock in the area around Aston Tirrold 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. 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.
In the older streets around Church of St Michael, the joint between an old wall and a newer frame is usually the first place rain gets in.

When to call us in Aston Tirrold

Keep an eye out for these signs:
- Gaps between timber frames and stone or brick
- Crumbling sand mastic round a window
- Draughts and rain around sash boxes
- Mastic that needs renewing before redecorating
For landlords with property near Cholsey station, older sash windows in a rental need their mastic kept sound to keep the weather out.

What happens if it’s left?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Aston Tirrold can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

FAQs for Aston Tirrold
Do you work for landlords with property near Cholsey station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.
Will you come out to Aston Tirrold?
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.
Can you quote for more than one area?
Yes, and it often makes sense. Doing several areas at once is normally more efficient.
Do I have to be there?
If the work is inside, we need someone to let us in. After that, you can carry on with your day.
What exactly is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us and we’re fully insured.
Can sand mastic be painted?
It’s traditionally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
Do you remove the old sealant?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Different surfaces, different methods
Timber door frames
Period doors in stone or brick openings are often pointed with sand mastic. The method is the same as for windows.
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
Keeping the joints in good condition
Good habits help new joints last longer. Our tips:
- Make sure water runs off the sill
- Get any rot dealt with first
- Avoid heavy scraping on the mastic joint
- Do not paint over the new mastic
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
