Sand mastic for sash & case windows in Matching Tye, Essex
Sand mastic across Matching Tye and nearby, with every bit of old sealant taken out first.
- Gaps between timber frames and stone or brick
- Old cement repairs round a window that have failed
- Mastic worn away on windows facing the weather
Sand mastic in Matching Tye
Traditional burnt sand mastic blends with stone and brick surrounds. It’s a good fit for period properties where a modern sealant bead would stand out. We work on sash and case windows, tenement windows and brick reveals, and the jobs we see most are modern sealant on a period surround and failed mastic on an exposed elevation.
Around Matching Tye, 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.
There’s a 12-month guarantee on every job, whatever its size.

Can you help a landlord with a rental near Harlow Mill station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or email us with the address and a few details, and we will give you a fixed price before any work starts.
Do you cover smaller places like Matching Tye?

What should I tell you?
A short description and the location, plus pictures if you have them. We will ask anything else we need to know.
Do the sealants smell?
Sometimes, a little. It fades as the sealant cures, and ventilation helps.

Do you offer different sealant colours?
In most cases you can choose. We will explain which colours are available and agree one before work begins.

DIY sealant or a professional job?
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so just mention it when you contact us.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Related advice
What sand mastic looks like in Matching Tye
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as Barrington Hall (about 4.5 miles north-east) nearby, there’s older building stock in the area around Matching Tye as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
For an older house near a landmark such as Parish Church of St Mary, the joint between an old wall and a newer frame is generally the first place rain gets in. For landlords with property near Harlow Mill station, cracked sand mastic around sash windows lets in the draughts tenants complain about.

Why act early in Matching Tye
If you are redecorating, renew the mastic first. Painting over failed mastic doesn’t seal it and traditional guidance is to leave the new mastic unpainted. Older cottages and farmhouses around Matching Tye can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.

Keeping the joints in good condition
After the cure time, these simple habits help:
- Leave the new mastic unpainted
- Check with your local planning authority if your home is listed
- Renew mastic before redecorating the windows
- Take care around the mastic when scraping paint
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Once mastic starts to crumble, rain gets in. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
