How we handle sand mastic in St Vincent's Hamlet
Sand mastic suits most period window surrounds. Newer frames normally get a flexible sealant instead, and we’ll talk through which suits your home. We work on stone surrounds, tenement windows and brick reveals, and people most often call us about window mastic to renew ahead of painting and open joints round the window box.
Mastic can only go onto a dry, clean joint, so window work in St Vincent's Hamlet is booked around the forecast. Let us know about access to all the frames, upstairs ones included.
All our work is covered by a 12-month guarantee.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What we do, step by step
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take anything from a few hours to a full day, depending on how many windows. Somewhere like St Vincent's Hamlet 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.
- We check the window surrounds and agree which joints need renewing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic isn’t too thick.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Tell us about any water getting in
- Plan for the work area to be out of bounds to pets and children

Advice
St Vincent's Hamlet homes and the weather
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Hare Hall (about 3 miles south-west) are a reminder that the area around St Vincent's Hamlet has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
For site and facilities teams at buildings such as Drapers' Maylands Primary School, its window and door frames need their mastic kept sound, just like a home’s. Homes close to Church of St Thomas include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Don’t run silicone over sand mastic
- Ask us before painting near the mastic
- Take care around the mastic when scraping paint
- Ask a joiner to look at soft timber first
Avoid painting over the new mastic, which is the traditional advice. Ask us before any decorating around it.
Gaps round a sash box let in draughts and rain. Left, the gap tends to get bigger.
