Why act early in Awbridge
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. Around Awbridge, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

How we handle sand mastic in Awbridge
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. Renewing it closes the gap and tidies the surround. We work on period & listed homes, sash and case windows and stone surrounds, and common reasons people get in touch are open joints round the window box and failed mastic on an exposed elevation.
Homes in small places like Awbridge often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
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 fails, we can still redo it.

Windows and doors in Awbridge
With historic houses such as Mottisfont Abbey (about 2 miles north) nearby, there’s older building stock in the area around Awbridge as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you live in an older home near Church of All Saints, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Awbridge Primary School, its window and door frames need their mastic kept sound, just like a home’s.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Do not paint over the new mastic
- Keep sills and gutters clear so water drains away
- Ask the planning authority about consent for listed or conservation-area homes
- Avoid heavy scraping on the mastic joint
When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
What we do, step by step
When we arrive, we look over the joints with you first. We protect the surfaces around the joints before we start. The work normally takes anything from a few hours to a full day, depending on how many windows. In a small place like Awbridge, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Large voids are packed out first, so the mastic is not too thick.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
