Sand mastic in Bricket Wood
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic is the traditional choice, and we can replace one with the other. We’re often asked to deal with mastic worn away on windows facing the weather and crumbling sand mastic round a window, across timber door frames, brick reveals and sash and case windows.
In a smaller place like Bricket Wood, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That’s hard on the mastic around frames and sills.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. We suggest:
- Leave the new mastic unpainted
- Make sure water runs off the sill
- Find out about consent before window work on a listed home
- Avoid heavy scraping on the mastic joint
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
Questions from Bricket Wood
Is Bricket Wood in your area for sand mastic?
Yes, Bricket Wood is within the area we cover. Our work covers London and the South East. You can call 0345 464 0079 or send us an email and tell us what needs doing, and we’ll send you a clear quote.
Is Bricket Wood within the area you cover?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Will the old sealant be removed?
Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.
Where is Mr Mastic based?
Our base is Crawley, with over 20 years’ experience. Our area covers South East England, London and Scotland.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Do you guarantee sand mastic work?
Our 12-month guarantee covers every job, sand mastic included.
Should I use sand mastic or silicone?
Sand mastic usually suits period timber windows best. On modern frames, we’d normally use a flexible sealant, and we will explain why.
When to call us in Bricket Wood
Rain on the window surround works into any crack and loosens it further. Windows facing the weather tend to go first.
Signs it’s time to call us include:
- Open joints round the window box
- A silicone bead on a sash window that spoils the look
- Draughty sash windows at the surround
- Cement or filler used on old window joints that has cracked
Rented homes near Bricket Wood station change hands often, and any sash windows need sound mastic to keep draughts and rain out.

What happens if it’s left?
Filling over old, loose mastic does not last. Raking out and preparing the joint gives it a sound base so the new work lasts. In a smaller place like Bricket Wood, 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.
What you pay reflects the work, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

Windows and doors in Bricket Wood
Historic houses like High Elms Manor (about 1.1 miles west) are a reminder that the area around Bricket Wood has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.
If you look after a building such as Mount Pleasant Lane Primary School, the mastic around its windows and doors needs looking after like any other building’s. In the older streets around Church of All Saints, the joint between an old wall and a newer frame is usually the first place rain gets in.
