Sand mastic in Ickleford
Our applicators renew the sand mastic around sash and case windows and doors in stone and brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. Common call-outs are for failed mastic on an exposed elevation and mastic round period door frames that has failed, on period & listed homes, brick reveals and stone surrounds.
In a village or hamlet like Ickleford, older cottages and farmhouses often have timber windows set in stone or brick. Older buildings like these don’t always suit modern silicone, so the sealant has to be chosen to suit the building.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

The process
On the day, there’s very little for you to do. Show us the job and we will take it from there. The work itself takes a few hours per window, depending on the condition of the joints, including the tidy-up. Somewhere as small as Ickleford, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- First, we look at the surrounds with you and agree what needs doing.
- Old, loose mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- Sand mastic is mixed and applied by hand, then shaped to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Let us know about earlier repairs to the joints
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Keep sills and gutters clear so water drains away
- Take care around the mastic when scraping paint
- Sort the mastic before the decorators arrive
- Ask the planning authority about consent for listed or conservation-area homes
Keep paint scrapers and sanders off the mastic when redecorating. Hard scraping can loosen it.
It’s best to renew mastic before painting the windows. Paint over cracked mastic only covers it up.
When something else is needed
We’d rather tell you now than do work that will not last, so these are the limits:
- Cracked or broken glass
- Sash cords, weights and draught-proofing of the sashes
- Decisions on consent for listed homes

DIY versus a professional finish
If you are set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

What information do you need?
The location, the problem and the rough size of the job. If you can, email a few pictures.

Yes, it’s worth checking. Ask your local planning authority whether consent is needed for listed or conservation-area properties.
