Sand Mastic in Idbury
Problem with your window and door surrounds in Idbury? We cut out the old, prepare the joints and apply the right sealant, with a one-year guarantee.
- Gaps round a timber door in stone or brick
- Patchy fillers round a sash window
- Mastic that needs renewing before redecorating
How it works
We keep the work tidy and contained to the area we’re working on, so you can get on with your day. The job normally takes anything from a few hours to a full day, depending on how many windows, and we explain the cure time before we leave. For a village or hamlet like Idbury, the journey is planned in advance: 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 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 is not too thick.
- New sand mastic is applied and shaped by hand.
- We finish the mastic to a tidy line.
Before we arrive
- Tell us about access, such as stairs, a lift or high-level joints
- Let us know about parking restrictions
- Plan for the work area to be out of bounds to pets and children

Advice
How we handle sand mastic in Idbury
On many period windows, sand mastic looks right and suits the building. Newer frames generally get a flexible sealant instead and we will explain which is best for yours. We work on tenement windows, sash and case windows and stone surrounds, and common reasons people get in touch are gaps between timber frames and stone or brick and old cement repairs round a window that have failed.
Homes in small places like Idbury often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.
You get a 12-month guarantee, the same in Idbury as everywhere else we work.

Questions from Idbury
Do you work for landlords with property near Kingham station?
Yes, rental work is part of what we do. Just phone 0345 464 0079 or email us and tell us about the property, and we will send you a clear quote.
Do you cover smaller places like Idbury?
Yes. Idbury is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Will there be a smell?
Possibly a little. It fades as the sealant cures.
Can you seal over the old sealant?
No, and we never do. It may look fine at first, but the new layer lifts away from the old one. The old sealant has to come out completely.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Should I check with the council before work on a listed or conservation-area home?
Your local planning authority is the one to ask. They’ll tell you if consent is needed for work to your windows.
How long does sand mastic take to harden?
It skins over fairly quickly but takes longer to harden fully. We will tell you what to expect for your job.
Do you have insurance?
Yes, we’re fully insured.
How we quote for sand mastic
We don’t publish a price list, because no two jobs are the same. What we look at:

The cost depends on how much there is to do, how much old material has to come out and access to the work. We give a clear quote before any work starts.

A few details help us give you an accurate quote. When you ask for a quote, tell us:
- If it’s domestic, commercial or a hotel
- Any access issues, like height or stairs

DIY versus a professional finish
A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
Signs you need sand mastic in Idbury
Previous repairs in cement or silicone often trap water or crack away. They don’t suit the joint, and they generally need raking out.
The most common problems we see are:
- A silicone bead on a sash window that spoils the look
- Cement or filler used on old window joints that has cracked
- Tired mastic found when preparing windows for paint
- Crumbling sand mastic round a window
In the older streets around Church of St Nicholas, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
