How we handle sand mastic in Chickney
Across Chickney, we renew sand mastic around sash and case windows. Every joint is cleaned out and filled by hand, finished to suit the masonry. Common call-outs are for a silicone bead on a sash window that spoils the look and old sand mastic that has cracked, crumbled or fallen out, on timber door frames, brick reveals and period & listed homes.
Around Chickney, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

How the visit works
Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a single window, longer for several and we leave things clean and tidy. Somewhere like Chickney needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. 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.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit

- Try not to wet indoor joints just before the visit
- Keep pets and children clear of the area while we work

What sand mastic looks like in Chickney
With historic houses such as Horham Hall (about 1.7 miles north) nearby, there’s older building stock in the area around Chickney as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For landlords with property near Stansted Airport station, any sash windows need sound mastic to keep draughts and rain out. If you live in an older home near Church of St Mary the Virgin, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How to look after the new joints
Simple care keeps the joints in good condition. We recommend:
- Check with your local planning authority if your home is listed
- Take care around the mastic when scraping paint
- Leave the new mastic unpainted
- Inspect the joints round the windows every year or so
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at rather than patching it.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry so early renewal protects both.
Questions from Chickney
Is Chickney in your area for sand mastic?
Yes. We work across London and the South East, and Chickney is part of that. You can call 0345 464 0079 or email us and let us know what needs doing, and we’ll give you a clear quote.
Is Chickney within the area you cover?
Yes. Chickney 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.
How long does sand mastic take to go off?
The surface skins quite quickly and it hardens fully over a longer time. Timing depends on the weather and the joint.
Are you fully insured?
Yes, we’re fully insured.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.

How the job changes by surface
Tenement and terrace windows
Windows above ground floor need the right access. Let us know the floor and we will confirm access.
Stone surrounds
The stone is treated with care when the old mastic comes out.
Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In a small place like Chickney, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
