Sand Mastic in Monk's Hill
We cover Monk's Hill for traditional burnt sand mastic around sash and case windows and doors in stone and brick. Old material cut out, joints cleaned and sealed neatly.
- Old cement repairs round a window that have failed
- Gaps where the frame meets the masonry
- Draughty sash windows at the surround
What happens on the day
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it usually takes anything from a few hours to a full day, depending on how many windows. For a village or hamlet like Monk's Hill, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- We rake out the old mastic and clean the joint.
- Large voids are packed out.
- New sand mastic is applied and shaped by hand.
- The finish is dressed neatly.
How to prepare
- Clear the area around the work
- Mention if the joints have been sealed before
- Keep children and pets away from the work area

How we handle sand mastic in Monk's Hill
We work across Monk's Hill renewing sand mastic on sash windows and doors. Each joint is raked out, prepared and pointed by hand, finished to suit the masonry. We work on sash and case windows, stone surrounds and timber door frames, and the jobs we see most are wind and rain getting in round a sash window and window mastic to renew ahead of painting.
Somewhere as small as Monk's Hill, older homes often have timber frames set in stone or brickwork. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
Each job carries a 12-month guarantee, whatever its size.

Leave it or put it right?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in and new mastic seals them. Where a wall is exposed, as many are in small places like Monk's Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will explain what it covers.
Why us?
- Full insurance on every job
- Anti-fungal silicone where joints get wet
- 20+ years of sealant experience
- A 12-month guarantee on all work

What sand mastic looks like in Monk's Hill
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 Smarden Primary School, the mastic around its windows and doors needs looking after like any other building’s. For an older house near a landmark such as Church of St Michael, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Headcorn station, any sash windows need sound mastic to keep draughts and rain out.

Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it doesn’t work out, we can still put it right.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
When something else is needed
It helps to know what we can’t do too:
- Decayed frames that need repair
- Planning or listed building consent (your local planning authority decides)
- Sashes that rattle, stick or won’t open
If you’re not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer.

Your quote is based on your job. We look at:
- Whether old sealant or filler has to be cut out
- Working hours on commercial sites

Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Ask us before painting near the mastic
- Avoid heavy scraping on the mastic joint
Do not run silicone over the new mastic. If you see a crack, ask us to take a look rather than patching it.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
FAQs for Monk's Hill
Will you come out to Monk's Hill?
Yes. Monk's Hill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Can you help a landlord with a rental near Headcorn station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we will give you a clear price.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or send us an email.
What does sand mastic cost?
Size, access and the old material all affect the cost. Call for a quick quote.
Should I try DIY first?
That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
Is sand mastic better than silicone for my windows?
We’ll help you decide. Period homes often look best with sand mastic and newer frames suit modern sealant.
Is it possible to take out silicone and use sand mastic instead?
Yes, we do this often. All the old silicone is removed first so the mastic beds in well.
What the job involves on each surface
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We work on single windows or whole elevations.
Sash and case windows
The mastic round a sash window is on show so we finish it carefully.
