Sand mastic for homes and businesses in Frant
Silicone on a period window often looks wrong and is not always the right material. Sand mastic gives a finish that matches the age of the house and we can swap the silicone for it. We work on timber door frames, brick reveals and period & listed homes, and people most often call us about a silicone bead on a sash window that spoils the look and mastic round period door frames that has failed.
In a village or hamlet like Frant, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, and sometimes a traditional sand mastic is the better choice.
All our work comes with a one-year guarantee, wherever you are in Kent.

When to call us in Frant
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
Most people get in touch after spotting something like this:
- Crumbling sand mastic round a window
- Gaps between timber frames and stone or brick
- Window mastic to renew ahead of painting
- Wind and rain getting in round a sash window
In the older streets around The Parish Church of St Alban, the joint between an old wall and a newer frame is generally the first place rain gets in.
What to look for in a quote
- When the joint can take water or movement
- Whether you can choose the colour
- What happens if they find a problem under the old sealant
- Whether they seal over old material or remove it
Windows and doors in Frant
Historic houses like Wadhurst Castle (about 3.5 miles south-east) are a reminder that the area around Frant 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
If you look after a building such as Frant Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s. Rented homes near Frant station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.

Aftercare tips
Joint life depends on how it’s used and looked after. We suggest:
- Clear gutters so water doesn’t pour onto the windows
- Don’t run silicone over sand mastic
- Ask the planning authority about consent for listed or conservation-area homes
- Check the mastic when you check the paintwork
Check the mastic when you check the paintwork. Small cracks are easier to deal with early.
An open joint round the box lets weather through. Left, the gap tends to get bigger as more mastic falls out.
Why act early in Frant
Not every filler suits an old window surround. Sand mastic matches what was there and that can be important for listed homes. Around Frant, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs, plus any working-time requirements on site. Ask us for a quote and we will explain what it covers.

Only a few details: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or email us.
When will the new mastic be hard?
The surface skins quite quickly, then hardens over a longer period. Timing depends on the weather and the joint.

If in doubt, phone 0345 464 0079 or drop us an email and we’ll say what we think.

DIY sealant or a professional job?
A DIY attempt does not rule out a professional job. We cut it out and start again.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
