Sand mastic in Beggar's Bush, done properly
A silicone bead around a sash window can look out of place and does not suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We are often asked to deal with weathered mastic on the most exposed windows and mastic round period door frames that has failed, across sash and case windows, tenement windows and brick reveals.
Homes in small places like Beggar's Bush often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

What we do, step by step
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. Somewhere like Beggar's Bush needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The finish is dressed so it sits neatly against the stone or brick.
Getting ready for the visit
- Keep children and pets away from the work area
- Let us know about earlier repairs to the joints

What happens if it’s left?
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Beggar's Bush, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Ask us for a quote and we’ll go through it with you.

What sand mastic looks like in Beggar's Bush
With historic houses such as St Leonard's Hill (about 4.3 miles north) nearby, there’s older building stock in the area around Beggar's Bush as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you look after a building such as Holy Trinity CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of St Michael and All Angels, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the 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 doesn’t work out, we can still put it right.

How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Keep modern sealant off the mastic
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
- Renew mastic before redecorating the windows
Don’t touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
