Can I do it myself?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
About our sand mastic in Hangersley
Our applicators renew the sand mastic around sash and case windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. If you have mastic round period door frames that has failed and old cement repairs round a window that have failed, we can put it right, on brick reveals, tenement windows and sash and case windows alike.
In a village or hamlet like Hangersley, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
All of our work is guaranteed for twelve months, in Hangersley and everywhere else we cover.

What else we do in Hangersley
Windows and doors in Hangersley
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. Historic houses like Avon Tyrrell House (about 4.1 miles south) are a reminder that the area around Hangersley 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.
Managing a site like Poulner Infant School? Then the mastic around its windows and doors needs looking after like any other building’s.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Keep sills and gutters clear so water drains away
- Get any rot dealt with first
- Don’t run silicone over sand mastic
- Renew mastic before redecorating the windows
Leave the new mastic unpainted, as traditional guidance advises. Ask us before any decorating around it.
Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.
Honest limits
In fairness, there are a few things sealant will not fix:
- Planning or listed building consent (your local planning authority decides)
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
