How we handle sand mastic in Stanford Dingley
Sand mastic is the traditional way to point the gap between a timber window frame and the stone or brick around it. It’s a mix of sand and a linseed-oil-based binder, applied by hand. On period homes, it looks right where silicone wouldn’t. Typical jobs include modern sealant on a period surround and mastic that needs renewing before redecorating, across brick reveals, period & listed homes and stone surrounds.
Somewhere as small as Stanford Dingley, older homes often have timber frames set in stone or brickwork. Older buildings like these do not always suit modern silicone, and sometimes a traditional sand mastic is the better choice.
All of our work is guaranteed for twelve months, in Stanford Dingley and everywhere else we cover.

Signs you need sand mastic in Stanford Dingley
Paint, silicone or cement used over old mastic causes problems. They don’t move with the timber, and they normally need raking out.
It’s worth asking for a quote if you see:
- Failed mastic on an exposed elevation
- Wind and rain getting in round a sash window
- Open joints round the window box
- Mastic that needs renewing before redecorating
In the older streets around Church of St Denys, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.
What your quote should include
- Are they insured?
- How much experience the applicator has
- What preparation is included
- Which colour the sealant will be
Work for landlords, hotels and businesses
A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.
We also work for property managers and facilities teams. Several sites can be quoted together.

Can I do it myself?
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
Stanford Dingley questions
I let a flat near Aldermaston station. Can you help?

Can you do sand mastic in Stanford Dingley?

Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
Does someone need to be in?
If the work is inside, we need someone to let us in. Once we’ve agreed the job, you don’t need to watch us work.
Do you hold any approvals?

Can I choose the sealant colour?
In most cases you can choose. We’ll tell you which colours the right product comes in.
Is it possible to take out silicone and use sand mastic instead?
Yes. The silicone is cut out and the joint cleaned, then point it with sand mastic.
What should I tell you?
Let us know what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.
Looking after it afterwards
Simple care keeps the joints in good condition. We recommend:
- Have rotten timber repaired before new mastic goes in
- Check the mastic when you check the paintwork
- Ask the planning authority about consent for listed or conservation-area homes
- Leave the new mastic unpainted
Keep gutters and sills clear so water runs away from the surround. Constant wetting wears the mastic faster.
Gaps round a sash box let in draughts and rain. The longer it’s left, the more the joint opens.
How the job changes by surface
Stone surrounds
Stone openings are rarely perfectly straight, so the joint varies in width. We shape it by hand to follow the stone.
Tenement and terrace windows
Rows of sash windows on tenements and terraces often need renewing together. We can do one window or several.
How the visit works
Once we are on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. Somewhere like Stanford Dingley needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First, we look at the surrounds with you and agree what needs doing.
- The loose and crumbling mastic is raked out and the joint cleaned.
- Deep voids are packed so the mastic is the right thickness.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The mastic is finished to sit tidily against the stone or brick.
Preparing for the visit
- Mention any leaks or damp you’ve noticed
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
How to get a quote

Advice
Stanford Dingley homes and the weather

In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Aldermaston station change hands often, and cracked sand mastic around sash windows lets in the draughts tenants complain about.
