How we handle sand mastic in Ibstone
We renew sand mastic around sash windows and doors in stone and brick. Out comes the old, loose mastic, and new mastic is applied and shaped by hand. If you are dealing with cement or filler used on old window joints that has cracked and failed mastic on an exposed elevation, we can put it right, whatever the surface.
Outdoor sealant needs dry, clean surfaces, so work on frames around Ibstone is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
You’re covered for a year from the day we finish. If there’s a problem with it, please phone 0345 464 0079 or drop us an email.

What sand mastic looks like in Ibstone
With historic houses such as Stonor Park (about 3 miles south) nearby, there’s older building stock in the area around Ibstone 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 Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Saunderton station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For site and facilities teams at buildings such as Ibstone CofE Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface
Tenement and terrace windows
Upper-floor windows need access planning. Tell us the height and we will confirm what’s needed.
Sash and case windows
The mastic round a sash window is on show, so a neat, even finish matters.
Why deal with it now?
Gaps round a sash window let in rain and draughts. Water can get to the frame and the masonry, so dealing with it now protects both. In a small place like Ibstone, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference.
Why us?
- ARBOMaster approved applicator
- Trusted Arbo and Everbuild sealants
- We leave the area clean and tidy

What else we do in Ibstone
How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Clear gutters so water doesn’t pour onto the windows
- Ask the planning authority about consent for listed or conservation-area homes
- Ask us before painting near the mastic
- Avoid patching sand mastic with silicone
Leave the new mastic alone while it firms up. It forms a skin fairly soon, but takes longer to harden fully.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes anything from a few hours to a full day, depending on how many windows, and the area is left clean. For a village or hamlet like Ibstone, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic is not too thick.
- We point the joint with sand mastic by hand.
- We finish the mastic to a tidy line.
Getting ready for the visit
- Keep pets and children clear of the area while we work
- Tell us about any previous sealing or DIY attempts
- Clear the area around the work

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
