Sand mastic in Bishopstone: local notes
Bishopstone 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, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of St Mary the Virgin, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Letting a property close to Herne Bay station? Then cracked sand mastic around sash windows lets in the draughts tenants complain about. Schools such as Reculver Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.
Bishopstone is about 2 miles east of Herne Bay, in Kent.

Common questions in Bishopstone
Do you work for landlords with property near Herne Bay station?
Yes. We work for letting agents and landlords as well as homeowners. Just phone 0345 464 0079 or send us an email with the address and what needs doing, and we’ll send you a clear quote.
Will you come out to Bishopstone?
Yes, we do. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
How long does the job take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Bigger jobs take longer, and we’ll tell you how long to expect.
Can I add another job to the visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Is there any odour?
Some sealants have a smell while they cure, which fades as it sets. Ventilation helps.
Can new sealant go over the old?
No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.
Are you fully insured?
Yes. We are fully insured for every job we do.
What guarantee comes with the work?
There’s a 12-month guarantee on every job, sand mastic included.
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.
Stone surrounds
Old stone surrounds are often uneven, so the joint varies in width. Sand mastic is shaped by hand to suit.
What we can’t put right
In fairness, there are a few things sealant will not fix:
- Timber that has rotted
- Putty and glazing repairs
- Sashes that rattle, stick or won’t open
If you’re not sure, just ring 0345 464 0079 or email us and we will give you a straight answer before you book.
Surfaces we seal
- Brick reveals
- Timber door frames
- Tenement windows
- Sash and case windows
- Stone surrounds
- Period & listed homes
Why deal with it now?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps and traditional guidance is to leave the new mastic unpainted. In a smaller place like Bishopstone, wherever a wall is exposed, a failed outside joint is a real source of damp. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.

How to look after the new joints
Once the sealant has cured, a few habits help it last:
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Clear gutters so water doesn’t pour onto the windows
- Ask us before painting near the mastic
When preparing windows for paint, take care around the mastic. Hard scraping can loosen it.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall so early renewal protects both.
DIY versus a professional finish
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What happens on the day
On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours for a single window, longer for several from start to finish. A visit to Bishopstone is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- We check each window surround and the condition of the joint.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Preparing for the visit
- Tell us if parking is tricky
- Mention any sign-in or site rules at work premises
- Move anything stored near the joints
