Sand mastic in Toothill
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Sand mastic is often favoured as a like-for-like material. We’re often asked to deal with failed mastic on an exposed elevation and gaps where the frame meets the masonry, on period & listed homes, tenement windows and stone surrounds.
Mastic can only go onto a dry, clean joint, so window work in Toothill is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Why act early in Toothill
A silicone bead can be quicker, but it can look wrong on a period surround. Sand mastic is the traditional material and blends with the stone or brick. Older cottages and farmhouses around Toothill can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

When to call us in Toothill
Water gets into small cracks in the mastic and pushes it out. Windows facing the weather tend to go first.
Most people get in touch when they notice something like this:
- Patchy fillers round a sash window
- Window mastic to renew ahead of painting
- Mastic dropping out of the joint
- Weathered mastic on the most exposed windows
In the older streets around Church of St John, the joint between an old wall and a newer frame is generally the first place rain gets in.
Questions to ask before you book
- What guarantee comes with the work
- What happens if they find a problem under the old sealant
- Which colour the sealant will be
- Whether the sealant suits the joint
Your questions about sand mastic in Toothill
Do you cover smaller places like Toothill?
Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you do sand mastic in Toothill?
Yes, Toothill is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or email us with a few details of the job.
Do you work for letting agents?
Yes. Domestic, commercial and hotel work are all part of what we do.
Can you seal over the old sealant?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. We remove it all first.
How long will you be here?
As a guide, most jobs take a few hours per window, depending on the condition of the joints. Bigger jobs take longer, and we’ll say how long yours will take.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Where do you work from?
Our base is Crawley. We work across South East England, London and Scotland.
Can old silicone round a sash window be swapped for sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
Work for landlords, hotels and businesses
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance.
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

Surface by surface
Sash and case windows
On a sash window, the mastic joint shows on the outside, so a neat, even finish matters.
Brick reveals
Sand mastic is also used where timber frames meet brick. It suits older brickwork.
Windows and doors in Toothill
Historic houses like South Stoneham House (about 4.3 miles south-east) are a reminder that the area around Toothill has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.
If you look after a building such as The Mountbatten School, the mastic around its windows and doors needs looking after like any other building’s. If you let a flat or house near Romsey station, older sash windows in a rental need their mastic kept sound to keep the weather out.
