How we handle sand mastic in Wigginton
Sand mastic doesn’t last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We work on brick reveals, stone surrounds and tenement windows, and the jobs we see most are wind and rain getting in round a sash window and patchy fillers round a sash window.
Around Wigginton, 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.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or drop us an email.

Should I try it myself first?
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
What the job involves on each surface
Timber door frames
Round a period front door, sand mastic gives the right look.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.

Your questions about sand mastic in Wigginton
Will you come out to Wigginton?
Yes. Wigginton is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.
Do I need to be at home?
For indoor joints, yes, someone needs to let us in. Once we’ve agreed the job, you do not need to watch us work.
Is consent needed for window work on a listed home?
Check with your local planning authority. They’ll tell you if consent is needed for work to your windows.
Where is Mr Mastic based?
Our base is Crawley. Our area covers South East England, London and Scotland.
What do you put in the joint?
Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.
Do you work for landlords and businesses?
Yes. As well as householders, we work for landlords, agents, businesses and hotels.
How long does sand mastic take to go off?
It forms a skin fairly soon, then hardens over a longer period. Timing depends on the weather and the joint.

Looking after it afterwards
A little care helps the new joints last. Our advice:
- Plan mastic work ahead of painting
- Do not run silicone over sand mastic
- Have rotten timber repaired before new mastic goes in
- Inspect the joints round the windows every year or so
Avoid sealing over the mastic with silicone. If you see a crack, ask us to take a look rather than patching it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
Frames and glazing around Wigginton
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Broughton Castle (about 3.5 miles north-east) are a reminder that the area around Wigginton 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 Saint Giles, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
