Typical jobs include draughts and rain around sash boxes and open joints round the window box, across stone surrounds, sash and case windows and tenement windows.

Should I try it myself first?
The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
How we quote for sand mastic
Call for a quick quote. The main things that affect it are:
- Any working-time requirements on site

- The number of rooms or windows
- Any mould that needs treating
Doing several joints on one visit normally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You will get one clear quote for the whole job.

The process
At the end, we look at the finished work together and tell you how long to leave it. The work normally takes a few hours for a single window, longer for several, depending on the size of the job. For a village or hamlet like Bradenham, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we agree which joints need doing.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Mention any parking rules near the property
- On commercial sites, let us know about site rules
- Mention any tricky access

How the job changes by surface
Stone surrounds
Sand mastic sits naturally against stone. It finishes to look like part of the surround.
Period and listed homes
Period homes look their best with traditional materials.
Leave it or put it right?
A silicone bead can be quicker, but on period stone or brick it often looks out of place. Sand mastic suits the building and blends with the stone or brick. Where a wall is exposed, as many are in small places like Bradenham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first.

Windows and doors in Bradenham
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as West Wycombe Park House (about 1.8 miles south) nearby, there’s older building stock in the area around Bradenham as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
Schools such as Naphill and Walters Ash School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. If you live in an older home near Church of St Botolph, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

When to call us in Bradenham
Age is the main cause. Sand mastic is a maintenance item like any pointing and how long it lasts depends on the weather it faces.
It’s worth asking for a quote if you see:
- Old sand mastic that has cracked, crumbled or fallen out
- Draughty sash windows at the surround
- Window mastic to renew ahead of painting
- Mastic worn away on windows facing the weather
Letting a property close to Saunderton station? Then older sash windows in a rental need their mastic kept sound to keep the weather out.
