Sand mastic in Wroxall
Old sand mastic cracks, crumbles and falls out over time and gaps open up round the frame. We rake it out and renew it and tidies the surround. We work on timber door frames, period & listed homes and brick reveals, and common reasons people get in touch are cement or filler used on old window joints that has cracked and gaps between timber frames and stone or brick.
In a village or hamlet like Wroxall, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
A 12-month guarantee comes as standard, so you’re not left on your own once the job is done.

Wroxall: your questions answered
Do you cover smaller places like Wroxall?
Yes. Wroxall is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is sand mastic in a coastal place like Wroxall any different?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Do you work for landlords and businesses?
Yes. We work for householders, landlords, letting agents, businesses and hotels.
Is sand mastic better than silicone for my windows?
It depends on the window. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Can you work on commercial sites?
Yes. We work in offices, washrooms, hotels and other commercial premises. We can talk about working times when we quote.

How the visit works
A visit follows a simple pattern: we check the joints, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Wroxall, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- We dress the finish so it sits neatly against the masonry.
Getting ready for the visit
- On commercial sites, let us know about site rules
- Clear items away from the joints we are working on
- Mention any leaks or damp you’ve noticed

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Do not paint over the new mastic
- Get any rot dealt with first
- Look over the window mastic once a year
- Make sure water runs off the sill
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Fine cracks show the mastic is starting to fail. It’s easier to renew it before it drops out.
What sand mastic looks like in Wroxall
Wroxall is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on the mastic around older windows and doors, especially on the side facing the sea. 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.
Letting a property close to Shanklin station? Then any sash windows need sound mastic to keep draughts and rain out. In the older streets around St John's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Different surfaces, different methods
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Timber door frames
Round a period front door, sand mastic gives the right look.
DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
