Sand mastic for homes and businesses in Silver Hill
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for failed mastic on an exposed elevation and old cement repairs round a window that have failed, across stone surrounds, tenement windows and sash and case windows.
Around Silver Hill, 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.
The work is covered for a year after we finish. If anything isn’t right with it, phone 0345 464 0079 or email us.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.

Windows and doors in Silver Hill
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 Bateman's (about 4.4 miles west) are a reminder that the area around Silver Hill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
In the older streets around Holy Trinity, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Hurst Green Church of England Primary School and Nursery, larger buildings have plenty of frames, and the mastic around each one ages.

Signs you need sand mastic in Silver Hill
Age is the main cause. Even well-laid mastic needs renewing in time, depending on exposure and upkeep.
If you can see any of these, it’s time to have the joints looked at:
- Mastic worn away on windows facing the weather
- Mastic round period door frames that has failed
- Silicone on a period window that looks wrong
- Open joints round the window box
Letting a property close to Etchingham station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
Questions to ask before you book
- Which colour the sealant will be
- Is the old sealant removed completely?
- Which sealant they’ll use, and why
- What happens if they find a problem under the old sealant
How the job changes by surface
Timber door frames
Door frames get knocked and soaked and the mastic can crack early. We rake it out and renew it.
Sash and case windows
Sash windows are where we do most sand mastic work. Each joint round the box is raked out and renewed.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. Our tips:
- Keep sills and gutters clear so water drains away
- Inspect the joints round the windows every year or so
- Go gently near the mastic when preparing windows
- Ask a joiner to look at soft timber first
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
What happens if it’s left?
Not every draught comes from the sashes themselves. Gaps between the frame and the wall can be just as bad and new mastic seals them. Around Silver Hill, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.
