About our sand mastic in Elmfield
Burnt sand mastic is a traditional material blends with stone and brick surrounds. It’s a good fit for period properties, where modern sealant can look out of place. We work on tenement windows, sash and case windows and brick reveals, and the jobs we see most are gaps between timber frames and stone or brick and cement or filler used on old window joints that has cracked.
Houses in smaller places like Elmfield can stand more in the open than those in a built-up town. That’s hard on the mastic around frames and sills.
All our work comes with our 12-month guarantee.

Why deal with it now?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic does not seal it and traditional guidance is to leave the new mastic unpainted. In a smaller place like Elmfield, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.

What sand mastic looks like in Elmfield
Elmfield is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around older windows and doors, especially on the side facing the sea. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St John's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Ryde St Johns Road station, cracked sand mastic around sash windows lets in the draughts tenants complain about.
Elmfield is about 1 mile south-east of Ryde, in the Isle of Wight. Wherever you are in the PO33 postcode area, our applicators can take on sand mastic. Elmfield is one of 125 towns and villages in the Isle of Wight where we work. You can also see our page for Portsmouth, about 7 miles away.

Should I try it myself first?
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.

Common problems we fix in Elmfield
Decorating can disturb tired mastic. It’s often found when windows are being prepared for paint, which is a good time to renew it.
It’s worth asking for a quote if you see:
- Mastic worn away on windows facing the weather
- Draughty sash windows at the surround
- Open joints round the window box
- Modern sealant on a period surround
For site and facilities teams at buildings such as Oakfield Church of England Aided Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
Questions to ask before you book
- Is VAT in the price?
- How much experience the applicator has
- How the colour is chosen
- Whether the sealant suits the joint
What we do, step by step
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work usually takes a few hours per window, depending on the condition of the joints. A visit to Elmfield is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We look at the surrounds with you and agree the joints to renew.
- We remove the old, loose mastic.
- Deep gaps are packed so the mastic sits at the right depth.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Before we arrive
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children

Different surfaces, different methods
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Brick reveals
Loose mastic comes out and deep gaps are packed before the new mastic goes in.
Elmfield: your questions answered
Is sand mastic in a coastal place like Elmfield any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Will you come out to Elmfield?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Should I try DIY first?
Sometimes. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We will tell you what we are using and why.
Do I need permission for sand mastic on a listed building?
Yes, it’s worth checking. Your local planning authority can say if consent is needed for listed or conservation-area properties.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
Do you take out the old sealant first?
Yes, always, and completely. New silicone does not stick to old silicone, so any old material comes out before anything new goes in.
Is it possible to paint over sand mastic?
Sand mastic is normally left unpainted, as guidance on traditional windows advises. Ask us before decorating.
