Sand mastic in Salford, done properly
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 work on tenement windows, sash and case windows and stone surrounds, and people most often call us about mastic worn away on windows facing the weather and gaps where the frame meets the masonry.
Homes in small places like Salford often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

Common questions in Salford
I let a flat near Aspley Guise station. Can you help?
Yes, we work for letting agents and landlords. You can phone 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before any work starts.
Can you do sand mastic in Salford?
Yes, Salford is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job.
Is it worth trying it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
Can you replace silicone on a period window with sand mastic?
Yes, we do this often. The old silicone has to come out completely so the mastic can sit properly.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Do you take out the old sealant first?
Yes. All of the old material is cut out and the joint cleaned before resealing.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. Older cottages and farmhouses around Salford can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
A DIY attempt does not rule out a professional job. We remove it and do the joint properly.
Keeping the joints in good condition
Aftercare is simple:
- Avoid heavy scraping on the mastic joint
- Plan mastic work ahead of painting
- Avoid patching sand mastic with silicone
- Check with your local planning authority if your home is listed
Make sure water drains away from the window surround. Water sitting against the mastic shortens its life.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Crumbling stone or brickwork round the window
- Whether work needs listed building consent
- Decayed frames that need repair
If you are not sure, just ring 0345 464 0079 or email us and we will give you a straight answer.

What sand mastic looks like in Salford
Historic houses like Woburn Abbey (about 4.6 miles south-east) are a reminder that the area around Salford 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’s traditional sand mastic. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Mary the Virgin, the joint between an old wall and a newer frame is normally the first place rain gets in.
