About our sand mastic in Lane End
On many period windows, sand mastic looks right and suits the building. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. We are often asked to deal with gaps between timber frames and stone or brick and modern sealant on a period surround, across brick reveals, sash and case windows and period & listed homes.
Outdoor sealant needs dry, clean surfaces, so work on frames around Lane End is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Your job is guaranteed for a year, as with all our work.

What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic is the traditional material and blends with the stone or brick. Older cottages and farmhouses around Lane End can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint normally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, ring 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
Aftercare tips
To keep the joints looking good and working properly:
- Check with your local planning authority if your home is listed
- Leave the new mastic unpainted
- Keep sills and gutters clear so water drains away
- Ask a joiner to look at soft timber first
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens as more mastic falls out.
When it isn’t the sealant
Honest advice matters more to us than a booking, so here’s what new sealant won’t do:
- Planning or listed building consent (your local planning authority decides)
- Decayed frames that need repair
- Cracked or broken glass
If in doubt, call 0345 464 0079 or send us an email and we’ll say what we think before booking.

In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
