Sand mastic for homes and businesses in Anthill Common
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on period & listed homes, timber door frames and tenement windows, and the jobs we see most are tired mastic found when preparing windows for paint and patchy fillers round a sash window.
Outdoor sealant needs dry, clean surfaces, so work on frames around Anthill Common is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.

Should I try it myself first?
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 doesn’t work out, we can still put it right.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.

Why act early in Anthill Common
Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. In a small place like Anthill Common, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Instead of a standard rate, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Looking after it afterwards
So the new joints stay in good condition:
- Look over the window mastic once a year
- Check with your local planning authority if your home is listed
- Sort the mastic before the decorators arrive
- Leave the new mastic unpainted
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
It’s best to renew mastic before painting the windows. Painting over failed mastic hides the problem for a while.
