How we handle sand mastic in Findon
We renew sand mastic around sash windows and doors set in stone or brick. Out comes the old, loose mastic, the joint is prepared and new mastic is shaped by hand. We work on stone surrounds, tenement windows and brick reveals, and the jobs we see most are weathered mastic on the most exposed windows and silicone on a period window that looks wrong.
Outdoor sealant needs dry, clean surfaces, so work on frames around Findon is planned for dry weather. Tell us about access to every side of the house, including upper-floor windows.
Our work is backed for twelve months, and the guarantee is the same wherever you are.

FAQs for Findon
Will you come out to Findon?
Yes, Findon is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.
Can you help a landlord with a rental near West Worthing station?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before work begins.
Are you an approved applicator?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.
Can you replace silicone on a period window with sand mastic?
Usually, yes. With the silicone removed and the joint cleaned, sand mastic is applied by hand.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s built up in the joint by hand and shaped to suit the surround.
Can you do several jobs on one visit?
Yes. Tell us about everything you’d like done and you will get one quote.
Is it OK to seal over old sealant?
No, because it fails. The old sealant always comes out first, so the new sealant bonds properly.
Which is right for my windows, sand mastic or modern sealant?
That depends on your windows. On many period windows, sand mastic looks right and suits the building, while modern frames normally get a flexible sealant.
Common problems we fix in Findon
Water gets into small cracks in the mastic and loosens it further. Exposed elevations normally fail first.
People usually contact us after spotting something like this:
- Tired mastic found when preparing windows for paint
- Cracked mastic round a front door frame
- A silicone bead on a sash window that spoils the look
- Crumbling sand mastic round a window
For an older house near a landmark such as The Parish Church of St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- What happens if the job turns out different
- How long to leave it before use
- Are they insured?
- Is VAT in the price?
What happens if it’s left?
Gaps round a sash window let in rain and draughts. Left, water can reach the timber and the wall so renewing it early protects the window. Older cottages and farmhouses around Findon can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You will know the price before we begin.

Looking after it afterwards
After the cure time, these simple habits help:
- Look over the window mastic once a year
- Renew mastic before redecorating the windows
- Clear gutters so water does not pour onto the windows
- Go gently near the mastic when preparing windows
Don’t run silicone over the new mastic. If anything cracks, get it looked at before trying a quick fix.
Sound mastic protects the frame. Once it fails, water can sit against the timber and timber that stays wet can rot.
How it works
You don’t need to clear the whole room or building before we come, just the space around the work. We protect the rest, and the work takes anything from a few hours to a full day, depending on how many windows for a typical job. Somewhere as small as Findon, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- Each surround is checked first.
- The joint is raked out and cleaned.
- We fill deep gaps so the new mastic isn’t too thick.
- We point the joint with sand mastic by hand.
- The finish is dressed neatly.
Getting ready for the visit
- Tell us about any previous sealing or DIY attempts
- Let us know if you’ve seen damp or leaks
- Where the joints are inside, avoid wetting them before we arrive

What sand mastic looks like in Findon
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. With historic houses such as Ecclesden Manor (about 3.8 miles south-west) nearby, there’s older building stock in the area around Findon as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
If you let a flat or house near West Worthing station, cracked sand mastic around sash windows lets in the draughts tenants complain about. If you look after a building such as St John the Baptist CofE Primary School, the mastic around its windows and doors needs looking after like any other building’s.
