How we handle sand mastic in Staple
Across Staple, we renew sand mastic around sash and case windows. Each joint is raked out, prepared and pointed by hand for a neat, traditional finish. If you have modern sealant on a period surround and draughty sash windows at the surround, we can help, on tenement windows, timber door frames and brick reveals alike.
Somewhere as small as Staple, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All our work comes with a 12-month guarantee.

How the visit works
Before we leave, we go over the finished joints with you. The visit itself usually takes a few hours per window, depending on the condition of the joints, depending on the size of the job. Somewhere as small as Staple, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- Large voids are packed out.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
How to prepare
- Let us know about stairs, lifts or work at height
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children

Sand mastic in Staple: local notes
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Goodnestone Park (about 1.9 miles south-west) are a reminder that the area around Staple has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For landlords with property near Adisham station, cracked sand mastic around sash windows lets in the draughts tenants complain about. Homes close to Church of St James include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Quotes for sand mastic in Staple
We don’t publish a price list. What we look at:
- Any working-time requirements on site
- How many areas need sealing
- The number and length of the joints
- Any mould that needs treating
What it costs depends on how much there is to do, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts.
What to tell us for a quote
The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:
- Whether it’s a home or a business
- Whether it has been sealed before
- Roughly how big the job is
- Any access issues, like height or stairs
Getting a quote is simple: let us know the job and the location. A few pictures by email make the job easier to understand, and we’ll take it from there.
Looking after it afterwards
Looking after new joints is easy, and it makes a real difference:
- Find out about consent before window work on a listed home
- Check the mastic when you check the paintwork
- Renew mastic before redecorating the windows
- Ask us before painting near the mastic
Don’t touch or press the mastic while it hardens. It skins over quickly, but takes longer to harden fully.
Sound mastic protects the frame. Failed mastic lets water reach the timber, which can lead to rot.
DIY versus a professional finish
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, 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.
What the job involves on each surface
Tenement and terrace windows
Tenements and terraces often have many sash windows with ageing mastic. We work on single windows or whole elevations.
Stone surrounds
We take care not to mark the stone while raking out the old mastic.
