Sand mastic in Kenardington, done properly
Old sand mastic cracks, crumbles and falls out over time, leaving gaps round the window. Renewing it closes the gap so the surround looks right again. We work on sash and case windows, tenement windows and timber door frames, and common reasons people get in touch are gaps between timber frames and stone or brick and failed mastic on an exposed elevation.
Mastic can only go onto a dry, clean joint, so window work in Kenardington is booked around the forecast. Tell us about access to every side of the house, including upper-floor windows.
All our work is covered by a one-year guarantee, wherever you are in Kent.

Work for landlords, hotels and businesses
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.
For anyone letting property in or around Kenardington, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.
DIY versus a professional finish
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
What we can’t put right
Honest advice matters more to us than a booking, so here’s what sealant cannot fix:
- Cracked or broken glass
- Sash cords, weights and draught-proofing of the sashes
- Decisions on consent for listed homes
If you’re not sure, just call 0345 464 0079 or drop us an email and we’ll give you a straight answer.

FAQs for Kenardington
Can you do sand mastic in Kenardington?
Yes, Kenardington is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or send us an email and let us know what needs doing, and we will give you a clear price.
Will you come out to Kenardington?
Yes. Kenardington is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
I’m a tenant. Can you help?
Of course. Ask your landlord first, and we can send them the quote if that helps.
Are you insured?
Yes. We are fully insured for every job we do.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We’ll tell you what to expect for your job.
Is it possible to paint over sand mastic?
The usual advice is to leave sand mastic unpainted. If you are redecorating the window, ask us first and we will talk you through it.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They decide whether consent is needed for work to your windows.

When to call us in Kenardington
Age is the main cause. Sand mastic is a maintenance item like any pointing, depending on exposure and upkeep.
The most common problems we see are:
- Patchy fillers round a sash window
- Gaps round a timber door in stone or brick
- Tired mastic found when preparing windows for paint
- Mastic dropping out of the joint
If you let a flat or house near Appledore (Kent) station, any sash windows need sound mastic to keep draughts and rain out.
Questions to ask before you book
- Whether they’re fully insured
- Is VAT in the price?
- Whether you can choose the colour
- What happens if they find a problem under the old sealant
How it works
There isn’t much for you to do on the day. Show us the job and we will take it from there. The work itself takes a few hours for a single window, longer for several from start to finish. Somewhere as small as Kenardington, 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.
- We rake out the old mastic and clean the joint.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Before we arrive
- On commercial sites, let us know about site rules
- Mention any tricky access
- Let us know about earlier repairs to the joints
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job, and we’ll come back to you with a quote.
Advice
Frames and glazing around Kenardington
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Aftercare tips
Simple care keeps the joints in good condition. We recommend:
- Find out about consent before window work on a listed home
- Don’t run silicone over sand mastic
- Inspect the joints round the windows every year or so
- Ask us before painting near the mastic
Do not run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
