How we handle sand mastic in Bray
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it so the surround looks right again. We work on stone surrounds, tenement windows and brick reveals, and common reasons people get in touch are patchy fillers round a sash window and modern sealant on a period surround.
In a village or hamlet like Bray, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes as standard, so you’re covered after we have gone.

What the job involves on each surface
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. Sand mastic seals the joint round it.

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
What sand mastic looks like in Bray
Historic houses like Dorney Court (about 1.3 miles east) are a reminder that the area around Bray has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For site and facilities teams at buildings such as Dorney School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to St Michael's Church include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For landlords with property near Taplow station, any sash windows need sound mastic to keep draughts and rain out.

What happens if it’s left?
Silicone might seem the quicker option, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Bray can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

The process
Once we are on site, we check the joints match what you told us. 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 Bray needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- We check the window surrounds and agree which joints need renewing.
- We rake out the old mastic and clean the joint.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Let us know about parking restrictions
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
