How we handle sand mastic in Arreton
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. Common call-outs are for window mastic to renew ahead of painting and modern sealant on a period surround, across brick reveals, stone surrounds and tenement windows.
Mastic can only go onto a dry, clean joint, so window work in Arreton is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
Whatever the size of the job, it’s backed by our one-year guarantee in Arreton and across the Isle of Wight.

What else we do in Arreton
Windows and doors in Arreton
Historic houses like Arreton Manor (about 0.5 miles north-west) are a reminder that the area around Arreton has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you live in an older home near St. George's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Why act early in Arreton
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Older cottages and farmhouses around Arreton can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Leaving a failed joint usually makes the job bigger, not smaller. If you are unsure, ring 0345 464 0079 or drop us an email for an honest opinion and a quote.
Why us?
- Experience in homes, commercial sites and hotels
- We never seal over old sealant
- Sanitary silicone with an anti-fungal additive in wet areas
- More than 20 years in sealant work

Common questions in Arreton
Do you cover Arreton for sand mastic?
Yes. We work across London and the South East, and Arreton is part of that. You can phone 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear price.
Do you cover smaller places like Arreton?
Yes, Arreton is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can old silicone round a sash window be swapped for sand mastic?
In most cases. We remove the silicone and clean the joint, then point it with sand mastic.
How long does sand mastic take to go off?
It forms a skin fairly soon and it hardens fully over a longer time. The weather and joint depth both affect it.
Are you an approved applicator?
Yes. Mr Mastic is an ARBOMaster approved applicator.
Is sand mastic better than silicone for my windows?
That depends on your windows. On many period windows, sand mastic looks right and suits the building and newer frames normally get a flexible sealant.
Can tenants book the work?
We are happy to deal with the tenant, landlord or agent. Just make sure your landlord agrees.
Do you offer different sealant colours?
Yes. White, clear and grey are common, and other colours are available for many products, and we agree the colour with you before work begins.
Do you need sand mastic in Arreton?
Over the years, sand mastic weathers. It dries out, cracks and loses its grip on the stone or timber.
Look out for these signs:
- Crumbling sand mastic round a window
- Window mastic to renew ahead of painting
- Wind and rain getting in round a sash window
- Gaps between timber frames and stone or brick
If you let a flat or house near Sandown station, older sash windows in a rental need their mastic kept sound to keep the weather out.
Before booking anyone
- Who does the work, and how experienced they are
- Whether they seal over old material or remove it
- What happens if they find a problem under the old sealant
- How long to leave it before use
How to look after the new joints
After the cure time, these simple habits help:
- Get any rot dealt with first
- Inspect the joints round the windows every year or so
- Sort the mastic before the decorators arrive
- Don’t run silicone over sand mastic
Leave the new mastic alone while it firms up. It skins over quickly but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
DIY versus a professional finish
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 does not work out, we can still put it right.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.
