What affects the quote in Herne Common
We don’t publish a price list. The quote depends on:
- Whether there’s mould to deal with
- How easy the joints are to reach
- The number and length of the joints
- How many areas need sealing
A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
Photos help, but a description is a good start. Please mention:
- How we’d reach the joints
- Pictures of the joints, sent by email
- Whether it’s a home or a business
- What’s wrong with the joints now
It all starts with a short chat. Tell us what’s wrong, where it is and how much there is, and we will explain how we’d tackle it. When it suits you, call 0345 464 0079 or send us an email.
Sand mastic in Herne Common
If your home is listed or in a conservation area, check with your local planning authority if consent is needed before window work. Like-for-like sand mastic is often the preferred finish. If you are dealing with gaps between timber frames and stone or brick and old sand mastic that has cracked, crumbled or fallen out, we can help.
In a village or hamlet like Herne Common, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

What the job involves on each surface
Sash and case windows
A sash window’s box frame sits in the masonry opening. Sand mastic seals the joint round it.
Brick reveals
Loose mastic comes out and deep gaps are packed before pointing.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Get any rot dealt with first
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
- Keep modern sealant off the mastic
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Sound mastic protects the frame. Failed mastic lets water reach the timber and timber that stays wet can rot.
Herne Common: your questions answered
Do you cover smaller places like Herne Common?
Yes, smaller places are covered as well as towns. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Do you work for landlords with property near Herne Bay station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we’ll give you a clear quote.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Will there be a smell?
Some sealants have a smell while they cure. Ventilation helps.
How long does sand mastic take?
Typically it takes a few hours per window, depending on the condition of the joints. Larger jobs naturally take longer, and we’ll say how long yours will take.
Can I choose the sealant colour?
Usually, yes. White, clear and grey are common, and other colours are available, and we agree the colour with you before we start.
Which is right for my windows, sand mastic or modern sealant?
For period timber windows in stone or brick, sand mastic is often the better fit. On modern frames, we’d normally use a flexible sealant.
What information do you need?
Where the job is, what the problem is and roughly how big it is. Photos by email help too.
Herne Common homes and the weather
Herne Common is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around older windows and doors, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Herne Bay station change hands often, and any sash windows need sound mastic to keep draughts and rain out. Homes close to Church of St Martin include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How it works
On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a single window, longer for several from start to finish. For a village or hamlet like Herne Common, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- We dress the surface so it sits neatly against the masonry.
How to prepare
- Move anything stored near the joints
- Let us know about stairs, lifts or work at height
- Mention any leaks or damp you’ve noticed
