How the visit works
There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for a single window, longer for several for a typical job. For a village or hamlet like Great Oakley, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- We apply the mastic by hand and shape it.
- We dress the finish so it sits neatly against the masonry.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Try not to wet indoor joints just before the visit

Advice
About our sand mastic in Great Oakley
Sand mastic skins over fairly quickly but full hardening takes longer. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Common call-outs are for window mastic to renew ahead of painting and mastic dropping out of the joint, across timber door frames, stone surrounds and tenement windows.
Somewhere as small as Great Oakley, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, large or small.

When to call us in Great Oakley

Frames and glazing around Great Oakley
Great Oakley is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Homes close to Parish Church of All Saints include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Questions from Great Oakley
Do you cover smaller places like Great Oakley?
Yes, Great Oakley is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Is sand mastic in a coastal place like Great Oakley any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can I add another job to the visit?
Yes. Just list everything you need and we’ll quote it together.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Ask your local planning authority whether consent is needed for work on a listed home or in a conservation area.
Is it possible to take out silicone and use sand mastic instead?
In most cases. We remove the silicone and clean the joint before the sand mastic goes in.
Is there any odour?
It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
What information do you need?
Let us know what needs doing and where. If we need more, we’ll ask.
Can I do it myself?
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

How we quote for sand mastic
You’ll get a clear quote before work begins. It takes into account:
- When we can work, for business premises

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether the work is at height. Your quote takes all of that into account.
Helping us quote
When you contact us, these details help:
- The problem you’ve noticed

Getting a quote is simple: let us know what needs doing and where and its rough size. A few photos by email make the job easier to understand.
What happens if it’s left?
If you’re redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Where a wall is exposed, as many are in small places like Great Oakley, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts.
