Aftercare tips
So the new joints stay in good condition:
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
- Ask a joiner to look at soft timber first
- Keep sills and gutters clear so water drains away
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Sand mastic for homes and businesses in Orsett
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you have open joints round the window box and silicone on a period window that looks wrong, we can put it right.
Homes in small places like Orsett 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.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How do I get a quote for sand mastic in Orsett?
Every job is different, so each one gets its own quote. For a quick quote, call 0345 464 0079 or drop us an email and tell us what needs doing and where.
Can you replace silicone on a period window with sand mastic?
Generally, yes. With the silicone removed and the joint cleaned we point it with sand mastic.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. The weather and joint depth both affect it.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we will quote it together.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in.
Where do you work from?

Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. In a small place like Orsett, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not guesswork. That is why we ask a few questions first and agree the price before starting.

Orsett homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Rented homes near Stanford-Le-Hope station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about. For an older house near a landmark such as St Giles & All Saints Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For site and facilities teams at buildings such as Orsett Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

Different surfaces, different methods
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Stone surrounds
We take care not to mark the stone when the old mastic comes out.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
