Sand mastic for homes and businesses in Stoke Hammond
Across Stoke Hammond, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. If you have silicone on a period window that looks wrong and gaps round a timber door in stone or brick, we can put it right, on tenement windows, brick reveals and period & listed homes alike.
Around Stoke Hammond, 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.
Our work is backed for twelve months, in Stoke Hammond and everywhere else we cover.

Can I do it myself?
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Frames and glazing around Stoke Hammond
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 Bletchley Park (about 3.1 miles north) nearby, there’s older building stock in the area around Stoke Hammond as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
If you look after a building such as Sir Herbert Leon Academy, larger buildings have plenty of frames, and the mastic around each one ages. Letting a property close to Bletchley station? Then any sash windows need sound mastic to keep draughts and rain out. In the older streets around Church of St Luke, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
Stoke Hammond is about 3 miles south of Bletchley, in Milton Keynes. Stoke Hammond gets the same service as everywhere we cover: old sealant removed completely, careful preparation and a 12-month guarantee. 73 places in Milton Keynes are on our list, large and small.

How to look after the new joints
How long the joints last depends on use and care. Here’s what we suggest:
- Look over the window mastic once a year
- Ask the planning authority about consent for listed or conservation-area homes
- Don’t paint over the new mastic
- Go gently near the mastic when preparing windows
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look before trying a quick fix.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Landlord and commercial work in Stoke Hammond
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll quote.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
What we do, step by step
You don’t need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the work takes a few hours per window, depending on the condition of the joints for a typical job. Somewhere like Stoke Hammond needs a little journey planning: 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 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 isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Tell us about any previous sealing or DIY attempts
- For business premises, tell us about site rules or sign-in
- Move anything stored near the joints

Stoke Hammond: your questions answered

Yes, Stoke Hammond is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we will send you a clear quote.
I let a flat near Bletchley station. Can you help?
Yes, landlords and agents are among the people we work for. You can call 0345 464 0079 or drop us an email with the details for a clear quote.
Is consent needed for window work on a listed home?
Your local planning authority is the one to ask. They decide whether consent is needed.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours per window, depending on the condition of the joints. We’ll tell you when we quote.
What do you put in the joint?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator, and we’re fully insured.
Can old silicone round a sash window be swapped for sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
