How it works
Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere like East Hendred needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- We rake out the old mastic and clean the joint.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Clear the area around the work
- Let us know about stairs, lifts or work at height
- Mention if the joints have been sealed before

Advice
Sand mastic in East Hendred
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditional guidance is not to paint over it and we’ll advise if you are redecorating. Common call-outs are for draughty sash windows at the surround and failed mastic on an exposed elevation, on stone surrounds, brick reveals and sash and case windows.
Somewhere as small as East Hendred, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
There’s a 12-month guarantee on every job, whatever its size.

Common problems we fix in East Hendred
Previous repairs in cement or silicone often trap water or crack away. They do not suit the joint and we normally remove them.
Any of these means the joints need attention:
- Open joints round the window box
- Cracked mastic round a front door frame
- Mastic worn away on windows facing the weather
- Wind and rain getting in round a sash window
In the older streets around Church of St Augustine of Canterbury, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.

- Stone surrounds
- Tenement windows
- Brick reveals

- Timber door frames
- Period & listed homes
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Make sure water runs off the sill
- Avoid heavy scraping on the mastic joint
- Ask the planning authority about consent for listed or conservation-area homes
- Sort the mastic before the decorators arrive
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.
