Sand mastic in Stonebridge Green
Sand mastic doesn’t last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. If you are dealing with mastic worn away on windows facing the weather and tired mastic found when preparing windows for paint, we can help.
Homes in small places like Stonebridge Green 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 one-year guarantee, the same in Stonebridge Green as everywhere else we work.

Aftercare tips
To keep the joints looking good and working properly:
- Avoid patching sand mastic with silicone
- Ask a joiner to look at soft timber first
- Ask us before painting near the mastic
- Take care around the mastic when scraping paint
Look at the mastic when you look over the windows. Catching cracks early keeps repairs small.
Good mastic helps keep the frame dry. Once it fails, water can sit against the timber and timber that stays wet can rot.
Why act early in Stonebridge Green
If you are redecorating, renew the mastic first. Painting over failed mastic does not seal it, and the new mastic is traditionally left unpainted. Around Stonebridge Green, older homes often have timber in their floors and frames, and water through a failed joint can rot timber if it’s left.
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Is sand mastic better than silicone for my windows?
For period timber windows in stone or brick, sand mastic is often the better fit. Modern frames normally suit a flexible sealant, and we will explain why.
How long does sand mastic take to go off?
It skins over fairly quickly but takes longer to harden fully. We will explain what to expect before we leave.
What is sand mastic?
Sand plus a binder based on linseed oil. It’s built up in the joint by hand and finished to sit neatly against the masonry.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
Is there any odour?
Some sealants have a smell while they cure. Ventilation helps.
How long does sand mastic take?
As a guide, most jobs take anything from a few hours to a full day, depending on how many windows. Larger jobs naturally take longer.

Sand mastic in Stonebridge Green: local notes
With historic houses such as Godinton House (about 5 miles south-east) nearby, there’s older building stock in the area around Stonebridge Green as well as newer homes. 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.
Letting a property close to Charing station? Then older sash windows in a rental need their mastic kept sound to keep the weather out. For an older house near a landmark such as Church of St James, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as Egerton Church of England Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Honest limits
Sealant isn’t the answer to every problem, and we’d rather say so up front. Sealant won’t put right:
- Planning or listed building consent (your local planning authority decides)
- Masonry that needs repairing
- Sash cords, weights and draught-proofing of the sashes
If you’re not sure, just call 0345 464 0079 or email us and we’ll give you a straight answer before you book.
Joints and surfaces we work on

DIY versus a professional finish
If you’ve already had a go yourself, that’s fine. We cut it out and start again.
A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How the job changes by surface
Sash and case windows
The box of a sash and case window sits in the stone or brick opening. The gap round it is pointed with sand mastic.
Timber door frames
Sand mastic is used round timber door frames too. The method is the same as for windows.
The process
The work is kept neat and contained to the joints we’re treating, so you can get on with your day. Expect the work to take a few hours for a single window, longer for several, and we tell you how long to leave it before we go. In a small place like Stonebridge Green, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each surround and agreeing the joints to renew.
- We rake out the old mastic and clean the joint.
- Large voids are packed out first, so the mastic isn’t too thick.
- The mastic is mixed, pressed into the joint by hand and shaped.
- The mastic is finished to sit tidily against the stone or brick.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed
- Plan for the work area to be out of bounds to pets and children
