About our sand mastic in Great Stambridge
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. The old mastic is raked out, and new mastic is applied and shaped by hand. Common call-outs are for gaps round a timber door in stone or brick and gaps where the frame meets the masonry, across timber door frames, tenement windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Great Stambridge is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work is covered by a one-year guarantee.

What happens if it’s left?
New mastic over crumbling mastic will not hold. We remove the loose material first so the new work lasts. Around Great Stambridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.
Why book with us
- 12-month guarantee on every job
- Any old sealant cut out fully, not covered over
- Anti-fungal sanitary silicone in wet areas
- Neat joints and a tidy finish

Your questions about sand mastic in Great Stambridge
Do you work for landlords with property near Rochford station?
Yes. We work for landlords and agents as well as homeowners, and several properties can go on one quote. You can ring 0345 464 0079 or email us with the details for a clear quote.
Is Great Stambridge within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I use sand mastic or silicone?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Can you replace silicone on a period window with sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and finished to sit neatly against the masonry.
When will the new mastic be hard?
A skin forms quite soon, but full hardening takes longer. We will tell you what to expect for your job.
Is consent needed for window work on a listed home?
It’s best to ask your local planning authority first. Sand mastic is often favoured as like for like but the decision is theirs.
Frames and glazing around Great Stambridge
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Southchurch Hall (about 3.9 miles south) are a reminder that the area around Great Stambridge has older buildings as well as new. 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 an older house near a landmark such as Church of St Mary and All Saints, the joint between an old wall and a newer frame is normally the first place rain gets in. If you look after a building such as Stambridge Primary School, the mastic around its windows and doors needs looking after like any other building’s.

- Mastic dropping out of the joint
- A silicone bead on a sash window that spoils the look
- Draughts and rain around sash boxes

- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.

Advice
What sealant work cannot fix
Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:
- Decisions on consent for listed homes
- Sashes that need overhauling
- Decayed frames that need repair
If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer before booking.
Joints and surfaces we work on
- Sash and case windows
- Timber door frames
- Period & listed homes

Surface by surface
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
Brick reveals
We rake out the old mastic and pack deep voids before the new mastic goes in.
Looking after it afterwards
Aftercare is simple, and it makes a real difference:
- Ask the planning authority about consent for listed or conservation-area homes
- Inspect the joints round the windows every year or so
- Sort the mastic before the decorators arrive
- Keep sills and gutters clear so water drains away
Keep gutters and sills clear so water runs away from the surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
