Sand mastic in Ardleigh Heath
Silicone on a period window often looks wrong and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. We work on tenement windows, period & listed homes and stone surrounds, and people most often call us about patchy fillers round a sash window and draughts and rain around sash boxes.
Around Ardleigh Heath, 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.
We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

How we quote for sand mastic
There’s no set price list, because jobs vary so much. The quote depends on:
- How much there is to do
- When we can work, for business premises
- Access and height
- How much old sealant there is and how hard it is to remove
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Asking for a quote
There’s no need for technical detail. It helps if you can tell us:
- The problem you’ve noticed
- Whether it has been sealed before
- Pictures of the joints, sent by email
- Whether it’s a home or a business
Every job is quoted individually, so the first step is telling us about yours. Just ring 0345 464 0079 or send us an email with the details and send pictures if you have them.
What sealant work can’t fix
Before you book, it’s worth knowing the limits:
- Decisions on consent for listed homes
- Sashes that need overhauling
- Damaged stone surrounds
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before booking.
What we seal
- Tenement windows
- Period & listed homes
- Brick reveals
- Sash and case windows
- Timber door frames
- Stone surrounds
Looking after it afterwards
Simple care keeps the joints in good condition. Our advice:
- Leave the new mastic unpainted
- Make sure water runs off the sill
- Avoid patching sand mastic with silicone
- Renew mastic before redecorating the windows
Leave the new mastic unpainted, which is the traditional advice. If you are redecorating, ask us first.
Sound mastic protects the frame. Once it fails, water can sit against the timber, which can lead to rot.

Advice
Ardleigh Heath homes and the weather
Historic houses like Castle House (about 1.3 miles north-east) are a reminder that the area around Ardleigh Heath 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’s traditional sand mastic. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

DIY sealant or a professional job?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
