Sand mastic in Iden Green
Silicone on a period window often looks wrong and doesn’t suit the building. Sand mastic gives a finish that matches the age of the house, and we can replace one with the other. We work on sash and case windows, tenement windows and timber door frames, and people most often call us about mastic worn away on windows facing the weather and gaps round a timber door in stone or brick.
Around Iden Green, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
All our work is covered by our one-year guarantee.

What sand mastic looks like in Iden Green
Historic houses like Great Dixter (about 4.2 miles south) are a reminder that the area around Iden Green 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’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.
If you look after a building such as Benenden Church of England Primary School, its window and door frames need their mastic kept sound, just like a home’s.

DIY versus a professional finish
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that’s fine. We cut it out and start again, so tell us about it when you ask for a quote.
How the visit works
Every visit runs the same way: we look at the joints together, mask and protect the surrounding surfaces, do the work and tidy away. Most jobs take anything from a few hours to a full day, depending on how many windows. Somewhere as small as Iden Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Mention any parking rules near the property
- For indoor joints, keep the area dry beforehand if you can
- Tell us about any water getting in

Leave it or put it right?
An open joint round the frame lets weather in. Water can get to the frame and the masonry so renewing it early protects the window. Older cottages and farmhouses around Iden Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the size of the job, how much old material has to come out and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Signs you need sand mastic in Iden Green
Timber frames move with the seasons. That movement opens up the mastic joint little by little.
The most common problems we see are:
- Mastic round period door frames that has failed
- Modern sealant on a period surround
- Open joints round the window box
- Old cement repairs round a window that have failed
If you live in an older home near Church of St George, the joint between an old wall and a newer frame is normally the first place rain gets in.

How long will you be here?

I rent my home. Can I book you?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Is there any odour?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
How long does sand mastic take to harden?
Not straight away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
What do you put in the joint?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can I do it myself?
That depends on the joint. High-level, external movement and fire-rated joints are professional jobs, while a short indoor joint may be within reach.
