Sand mastic in Newington, done properly
Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. If you have weathered mastic on the most exposed windows and open joints round the window box, we can put it right, whatever the surface.
In a village or hamlet like Newington, 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 our one-year guarantee, wherever you are in Kent.

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
- Have rotten timber repaired before new mastic goes in
- Find out about consent before window work on a listed home
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
Fine cracks show the mastic is starting to fail. Renewing it then is simpler than waiting until it falls out.
How it works
There isn’t much for you to do on the day. Point us to the joints and we will get on with it. The job generally takes a few hours for a single window, longer for several, including the tidy-up. Somewhere as small as Newington, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each surround is checked first.
- The joint is raked out and cleaned.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Move anything stored near the joints
- Tell us about any water getting in
- Let us know about earlier repairs to the joints

Related advice
Can I do it myself?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and doesn’t move well, and the joint depth matters as much as the finish.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Quotes for sand mastic in Newington
We quote each job individually. These are the things that affect it:
- The number and length of the joints
- The product the joint needs
- Access and height
- Whether there’s mould to deal with
Leaving a failed joint generally makes the job bigger, not smaller, as water and mould keep getting in. If you are not sure whether it needs doing, phone 0345 464 0079 or send us an email and we will give you an honest view and a quote.
Asking for a quote
What to tell us when you ask for a quote:

Sand mastic in Newington: local notes
Newington is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. With historic houses such as Acrise Place (about 3.2 miles north) nearby, there’s older building stock in the area around Newington as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around Church of St Nicholas, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Questions from Newington
Does living near the coast affect sand mastic in Newington?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
I let a flat near Folkestone West station. Can you help?
Yes. We work for landlords and agents as well as homeowners, and several properties can be quoted together. Just call 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll give you a clear price.
Will there be a smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
How long will you be here?
That depends on how much there is to do, but most jobs take a few hours for a single window, longer for several. We’ll tell you when we quote.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. Ask us before you decorate around it and we’ll advise.
Do you offer different sealant colours?
We’ll suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
How do I get a quote for sand mastic in Newington?
Every job is different, so each one gets its own quote. For a quick quote, ring 0345 464 0079 or email us with a short description of the job.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.
