How we handle sand mastic in Chigwell
Sand mastic has long been used to fill the joint between timber frames and masonry. It’s made from sand and a linseed-oil-based binder and built up by hand. On older homes, it suits the building far better than silicone. Common call-outs are for silicone on a period window that looks wrong and mastic round period door frames that has failed, on stone surrounds, timber door frames and brick reveals.
Many houses in smaller places like Chigwell have conservatories, garden rooms or patio doors. Those joints need the same attention as the main windows, and any older timber or sash windows need a sealant that suits them.
Big or small, you get the same one-year guarantee in Chigwell and across Essex.

Your questions about sand mastic in Chigwell
Can you help a landlord with a rental near Chingford station?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Chigwell within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
How long does the job take?
A typical job takes a few hours for a single window, longer for several, including the preparation. We’ll confirm how long when we quote.
Do you guarantee sand mastic work?
All our work has a 12-month guarantee, and we’re fully insured.
Where do you work from?
We are based in Crawley, and we cover South East England, London and all of Scotland.
What’s sand mastic made of?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Will there be a smell?
Some sealants have a smell while they cure, which fades as it sets. Opening a window helps.
What we are called out for in Chigwell
Some old mastic was never deep enough. A thin layer does not hold well so we make sure the new mastic is the right thickness.
Keep an eye out for these signs:
- Open joints round the window box
- Patchy fillers round a sash window
- Cracked mastic round a front door frame
- Weathered mastic on the most exposed windows
Homes close to St Winifred include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What happens if it’s left?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, and the new mastic is traditionally left unpainted. Homes in smaller places like Chigwell can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and agree the price before starting.

Take a look at what affects the cost and our reviews.
DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.
Sand mastic in Chigwell: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Valentines Mansion (about 2.9 miles south) are a reminder that the area around Chigwell 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 is traditional sand mastic.
For site and facilities teams at buildings such as Limes Farm Infant School and Nursery, the mastic around its windows and doors needs looking after like any other building’s. Letting a property close to Chingford station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about.
