About our sand mastic in Ashburnham
Sand mastic doesn’t last for ever, leaving gaps round the window. Renewing it closes the gap and tidies the surround. If you have draughts and rain around sash boxes and failed mastic on an exposed elevation, we can help, whatever the surface.
Around Ashburnham, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.
Every job is covered by our 12-month guarantee.

Ashburnham homes and the weather
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.
Homes close to Parish Church of St Peter include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.
Ashburnham is about 5 miles north-west of Bexhill-on-Sea, in East Sussex.

What we’re called out for in Ashburnham
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
It’s worth asking for a quote if you see:
- Old sand mastic that has cracked, crumbled or fallen out
- Failed mastic on an exposed elevation
- Cracked mastic round a front door frame
- Mastic that needs renewing before redecorating
If you let a flat or house near Battle station, any sash windows need sound mastic to keep draughts and rain out.
Before you book anyone
- Who turns up on the day
- How long to leave it before use
- Whether the sealant suits the joint
- What guarantee comes with the work
Keeping the joints in good condition
How long the joints last depends on use and care. We suggest:
- Make sure water runs off the sill
- Do not paint over the new mastic
- Inspect the joints round the windows every year or so
- Avoid patching sand mastic with silicone
Look at the mastic when you look over the windows. Small cracks are easier to deal with early.
Crumbling mastic lets rain into the joint. That water can reach the timber frame and the wall, so renewing it early is worth it.
What we do, step by step
We bring everything the job needs with us. After a quick look at the joints together, the area is protected and the work begins. Most jobs take a few hours for a single window, longer for several. Somewhere like Ashburnham needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- We pack any deep voids first.
- The sand mastic is mixed and pressed into the joint by hand.
- The surface is finished to suit the stone or brick.
Getting ready for the visit
- Clear the area around the work
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Common questions in Ashburnham
Do you cover smaller places like Ashburnham?
Yes, Ashburnham is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Can you do sand mastic in Ashburnham?
Yes, Ashburnham is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job.
Do you remove the old sealant?
Yes, always, and completely. New sealant won’t bond properly to old, so any old material comes out before anything new goes in.
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.
What do you need from me for a quote?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or drop us an email.
Are you fully insured?
Yes. Full insurance covers our work.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.
Will you leave a mess?
Tidy work is part of the job. Nearby surfaces are protected, and the area is left clean when we finish.

Why deal with it now?
Draughts round a sash window aren’t always the sashes. Open mastic joints round the box can let air in, and renewing the mastic closes them. Where a wall is exposed, as many are in small places like Ashburnham, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
What it costs depends on the size of the job, how much old material has to come out and access to the work. We give a clear quote before we start, so you know where you stand.
