Sand mastic in Leverton

Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder and built up by hand. On period homes, it looks right where silicone wouldn’t. We’re often asked to deal with mastic that needs renewing before redecorating and mastic worn away on windows facing the weather, across tenement windows, timber door frames and sash and case windows.

In a village or hamlet like Leverton, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.

Leverton homes and the weather

The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Ramsbury Manor (about 4.6 miles west) nearby, there’s older building stock in the area around Leverton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

For an older house near a landmark such as Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Schools such as Chilton Foliat Church of England Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

What happens if it’s left?

Silicone might seem the quicker option, but it can look wrong on a period surround. Sand mastic suits the building and blends with the stone or brick. Older cottages and farmhouses around Leverton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. The price is agreed before we begin.

What information do you need?

A short description and the location, with photos by email if possible. If we need more, we will ask.

How do I get a quote for sand mastic in Leverton?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote and we’ll talk you through it.

Can you do several jobs on one visit?

Of course. Combining jobs makes good use of the visit.

Where are you based?

We are based in Crawley, West Sussex, and we work across South East England, London and Scotland.

Can you seal over the old sealant?

No, it will not last. It may look fine at first, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

Do you take out the old sealant first?

Yes, always, and completely. New sealant won’t bond properly to old, so the joint is cleaned back first.

Quotes for sand mastic in Leverton

The price is agreed before any work begins. It’s based on:

Any mould that needs treating
The number of rooms or windows
Access and height
Whether old sealant or filler has to be cut out

Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

What to tell us for a quote

There’s no need for technical detail. Just tell us:

The rough size of the job
Whether it’s a home or a business
How we’d reach the joints

What we can’t put right

Cracked or broken glass

How to look after the new joints

To keep the joints looking good and working properly:

Find out about consent before window work on a listed home
Make sure water runs off the sill
Ask a joiner to look at soft timber first
Leave the new mastic unpainted

When preparing windows for paint, take care around the mastic. It can be damaged by heavy scraping.

Small cracks are a sign the mastic is ageing. Renewing it then is simpler than waiting until it falls out.

The process

There is not much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a single window, longer for several. Somewhere like Leverton needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

We check each window surround and the condition of the joint.
The joint is raked out and cleaned.
Large voids are packed out.
New sand mastic is applied and shaped by hand.
We finish the mastic to a tidy line.

Getting ready for the visit
