How to look after the new joints
Good habits help new joints last longer. A few tips:
- Plan mastic work ahead of painting
- Leave the new mastic unpainted
- Go gently near the mastic when preparing windows
- Check with your local planning authority if your home is listed
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Renewing mastic before redecorating saves doing it twice. Paint over cracked mastic only covers it up.

FAQs for Pegwell
Is sand mastic in a coastal place like Pegwell any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Do you work for landlords with property near Ramsgate station?
Yes, we work for landlords and agents. You can phone 0345 464 0079 or drop us an email with the address and a few details, and we will give you a fixed price before work begins.
What sealant do you use?
We choose the sealant for the joint, not the other way round. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.
How long does sand mastic take to go off?
Not straight away. The skin forms first, and the full set comes later and we’ll give you an idea for your job.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Pegwell, along with the rest of our area.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
What exactly is sand mastic?
It’s the traditional filler for the joint round timber windows and doors. It combines sand with a linseed-oil-based binder.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.

Can I do it myself?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Why act early in Pegwell
Draughts round a sash window are not always the sashes. Gaps between the frame and the wall can be just as bad, and renewing the mastic closes them. Older cottages and farmhouses around Pegwell can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.

What sand mastic looks like in Pegwell
Pegwell is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on the mastic around older windows and doors, especially on the side facing the sea. London and the South East are among 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 Chilton Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Homes close to Church of St Laurence include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Pegwell is about 1 mile south-west of St Lawrence, in Kent.
