What affects the cost of sand mastic
There’s no set price list. The quote depends on:
- Whether the work is at height
- Any mould that needs treating
- The size of the job
- Any working-time requirements on site
Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we’ll give you an honest view and a quote.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
- If someone has resealed it before
- Photos by email, if that is easy
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you are ready, ring 0345 464 0079 or drop us an email.
Sand mastic in Ibthorpe, done properly
For a listed home or one in a conservation area, ask your local planning authority whether consent is needed for work to windows. Like-for-like sand mastic is often the preferred finish. We work on sash and case windows, tenement windows and brick reveals, and common reasons people get in touch are draughts and rain around sash boxes and open joints round the window box.
Outdoor sealant needs dry, clean surfaces, so work on frames around Ibthorpe is planned for dry weather. Let us know about access to all the frames, upstairs ones included.
Whatever the size of the job, you get the same 12-month guarantee in Ibthorpe and across Hampshire.

Your questions about sand mastic in Ibthorpe
Will you come out to Ibthorpe?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Can you do sand mastic in Ibthorpe?
Yes, Ibthorpe is within the area we cover. We work across London and the South East. You can call 0345 464 0079 or send us an email and let us know what needs doing, and we’ll give you a clear price.
Can I do it myself?

Of course. Check with your landlord; we can send the quote to them too.
Are you fully insured?

What do you need from me for a quote?
Tell us what needs doing and where, with photos by email if possible. We’ll ask anything else we need to know.
Why act early in Ibthorpe
Not every filler suits an old window surround. Sand mastic matches what was there, which can matter on listed and conservation-area homes. Where a wall is exposed, as many are in small places like Ibthorpe, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

How the visit works
There’s no need to move everything out, just the space around the work. Everything nearby is protected, and the job takes a few hours for a single window, longer for several in most cases. Somewhere as small as Ibthorpe, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by checking each surround and agreeing the joints to renew.
- Old, loose mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- We dress the surface so it sits neatly against the masonry.
Preparing for the visit
- Clear items away from the joints we’re working on
- Plan for the work area to be out of bounds to pets and children
- Mention any parking rules near the property

Advice
What the job involves on each surface
Stone surrounds
Stone surrounds suit sand mastic well. It finishes to look like part of the surround.
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Keeping the joints in good condition
Aftercare is simple:
- Keep modern sealant off the mastic
- Ask a joiner to look at soft timber first
- Inspect the joints round the windows every year or so
- Leave the new mastic unpainted
Do not touch or press the mastic while it hardens. It skins over quickly but needs longer to fully harden.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
Frames and glazing around Ibthorpe
With historic houses such as Stargroves (about 4.9 miles north-east) nearby, there’s older building stock in the area around Ibthorpe as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
For an older house near a landmark such as Church of St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What we are called out for in Ibthorpe
Sand mastic slowly weathers. It hardens, cracks and starts to come away from the frame or the masonry.
People usually contact us after spotting one of these:
- Mastic round period door frames that has failed
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
- Wind and rain getting in round a sash window
For site and facilities teams at buildings such as Hurstbourne Tarrant Church of England Primary School, larger buildings have plenty of frames, and the mastic around each one ages.
