Do you hold any approvals?

Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
Do the sealants smell?
It depends on the product. Some smell for a while, some hardly at all.

Can old silicone round a sash window be swapped for sand mastic?
Often, yes. Once the silicone is out and the joint prepared we point it with sand mastic.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.

What else we do in Binley
Honest limits
We’ll always be straight with you, so here’s what sealant cannot fix:
- Rotten sashes, sills or window boxes (a joiner’s job)
- Putty and glazing repairs
- Sash cords, weights and draught-proofing of the sashes
Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
What we seal
- Sash and case windows
- Period & listed homes
- Stone surrounds
- Tenement windows
- Timber door frames
- Brick reveals
How to look after the new joints
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Make sure water runs off the sill
- Sort the mastic before the decorators arrive
- Have rotten timber repaired before new mastic goes in
- Leave the new mastic unpainted
Leave the new mastic unpainted, as traditional guidance advises. If you are redecorating, ask us first.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.

Sand mastic in Binley: local notes
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Highclere Castle (about 3.8 miles north-east) nearby, there’s older building stock in the area around Binley as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
