About our sand mastic in Ivy Chimneys
Sand mastic does not last for ever and gaps open up round the frame. Renewing it closes the gap so the surround looks right again. We are often asked to deal with gaps round a timber door in stone or brick and failed mastic on an exposed elevation, across timber door frames, sash and case windows and stone surrounds.
Somewhere as small as Ivy Chimneys, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

Do you need sand mastic in Ivy Chimneys?
Scraping and sanding before painting can loosen old mastic. It’s often found when windows are being prepared for paint.
Keep an eye out for these signs:
- Gaps round a timber door in stone or brick
- Gaps where the frame meets the masonry
- Tired mastic found when preparing windows for paint
- Wind and rain getting in round a sash window
Schools such as Ivy Chimneys Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

Windows and doors in Ivy Chimneys
Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Hill Hall (about 2.4 miles south-east) are a reminder that the area around Ivy Chimneys has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
Homes close to Church of St John the Baptist include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we do, step by step
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes anything from a few hours to a full day, depending on how many windows.

- We look at the surrounds with you and agree the joints to renew.
- Old mastic and any loose material are raked out.
- Deep gaps are packed so the mastic sits at the right depth.
- We apply the mastic by hand and shape it.
- The surface is finished to suit the stone or brick.

Advice
Common questions in Ivy Chimneys
What guarantee comes with sand mastic in Ivy Chimneys?
Every job comes with our one-year guarantee, wherever it is. We are also fully insured and ARBOMaster approved.
Do you cover smaller places like Ivy Chimneys?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
What’s sand mastic made of?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and shaped to suit the surround.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Will it make a mess?
No. We work neatly, protect the area around the joints and tidy up afterwards.
Should I use sand mastic or silicone?
Sand mastic generally suits period timber windows best. Modern frames normally suit a flexible sealant, and we’ll explain why.
Can new sealant go over the old?
No. New silicone won’t bond to old silicone, and it traps any mould or water underneath. It all has to come out first.
Should I check with the council before work on a listed or conservation-area home?
Checking first is sensible. Your local planning authority can say if consent is needed for work on a listed home or in a conservation area.

How to look after the new joints
How long the joints last depends on use and care. We suggest:
- Go gently near the mastic when preparing windows
- Find out about consent before window work on a listed home
- Don’t paint over the new mastic
- Avoid patching sand mastic with silicone
Avoid sealing over the mastic with silicone. If anything cracks, get it looked at before trying a quick fix.
Good mastic helps keep the frame dry. Failed mastic lets water reach the timber, which can lead to rot.
Can I do it myself?
If you do try it yourself, take your time over the 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.
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
What affects the cost of sand mastic
There’s no set price list, because no two jobs are the same. What we look at:
- Mould in or behind the old joints
- Whether the work is at height
- The amount of work
- The type of sealant required
Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will explain what it covers.
Helping us quote
There’s no need for technical detail. It helps if you can tell us:
- Whether it has been sealed before
- What’s wrong with the joints now
- Pictures of the joints, sent by email
- Access, such as stairs, a lift or height
We don’t publish a price list, because every job is different. Instead, we give you a clear quote for your job. To get started, phone 0345 464 0079 or email us.
Why deal with it now?
Cement-based fillers and modern sealants do not always suit a period surround. Sand mastic is the like-for-like choice and that can be important for listed homes. In a small place like Ivy Chimneys, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
