How we handle sand mastic in Mackerel's Common
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. We work on sash and case windows, timber door frames and brick reveals, and people most often call us about failed mastic on an exposed elevation and window mastic to renew ahead of painting.
In a village or hamlet like Mackerel's Common, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Common questions in Mackerel's Common
Do you work for landlords with property near Billingshurst station?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before we start.
Is Mackerel's Common within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.
Can you work on commercial sites?
Yes. We can plan bigger jobs in stages.
Can sand mastic be painted?
It’s traditionally left unpainted, which is what traditional guidance recommends. Ask us before decorating.
Where do you work from?
We are based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Is consent needed for window work on a listed home?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.
Will you leave a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Leave it or put it right?
New sash windows are a major, costly change and on a listed home, consent may be needed. Where the frames are in good order, new mastic seals the surround. In a small place like Mackerel's Common, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

Sand mastic in Mackerel's Common: local notes
With historic houses such as Petworth House (about 4.6 miles south-west) nearby, there’s older building stock in the area around Mackerel's Common as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you let a flat or house near Billingshurst station, any sash windows need sound mastic to keep draughts and rain out.
