How we handle sand mastic in Bramdean
Fresh sand mastic forms a skin quite soon, but it takes longer to harden fully. Traditionally, sand mastic is left unpainted, so ask us before you decorate. Typical jobs include wind and rain getting in round a sash window and mastic round period door frames that has failed, on sash and case windows, period & listed homes and stone surrounds.
In a village or hamlet like Bramdean, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
Whatever the size of the job, you get the same 12-month guarantee in Bramdean and across Hampshire.

Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Frames and glazing around Bramdean
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. Historic houses like Hinton Ampner House (about 1.3 miles west) are a reminder that the area around Bramdean has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St Simon and St Jude include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens if it’s left?
Replacing sash windows is a big decision for a period home, and in listed buildings it may need consent. If the frames are sound, renewing the mastic deals with gaps and draughts at the surround. Where a wall is exposed, as many are in small places like Bramdean, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Will you come out to Bramdean?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it OK to seal over old sealant?
No. The old sealant always comes out first.

Will it make a mess?

Is consent needed for window work on a listed home?
Speak to your local planning authority before work starts. Like-for-like sand mastic is often the preferred finish, but they decide.
When it isn’t the sealant
In fairness, there are a few things sealant will not fix:
- Putty and glazing repairs
- Sashes that need overhauling
- Crumbling stone or brickwork round the window

- Draughty sash windows at the surround
- Cement or filler used on old window joints that has cracked
- Mastic round period door frames that has failed
- Crumbling sand mastic round a window
In and around Bramdean, as anywhere, good sand mastic starts with a clean, dry, properly prepared joint.

How it works
There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The job generally takes anything from a few hours to a full day, depending on how many windows from start to finish. Somewhere as small as Bramdean, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- 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.
- The finish is dressed so it sits neatly against the stone or brick.
How to prepare
- Tell us about access, such as stairs, a lift or high-level joints
- For business premises, tell us about site rules or sign-in
- Keep pets and children clear of the area while we work

Related advice
Looking after it afterwards
A little care helps the new joints last. Our advice:
- Ask a joiner to look at soft timber first
- Plan mastic work ahead of painting
- Keep sills and gutters clear so water drains away
- Ask the planning authority about consent for listed or conservation-area homes
Don’t run silicone over the new mastic. If anything cracks, get it looked at rather than patching it.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
