Sand mastic for homes and businesses in Enfield Wash
Sand mastic does not last for ever, leaving gaps round the window. We rake it out and renew it so the surround looks right again. We work on sash and case windows, tenement windows and timber door frames, and the jobs we see most are mastic worn away on windows facing the weather and tired mastic found when preparing windows for paint. Whether you are looking for a local mastic man, a silicone specialist or a sealant company in Enfield Wash, that’s what we do.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Enfield Wash.
A one-year guarantee comes with the work, just as it does everywhere we cover.

What happens if it’s left?
If you are redecorating, renew the mastic first. Paint over cracked mastic will not stop the gaps, and the new mastic is traditionally left unpainted. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and by the time it shows on a wall or ceiling in Enfield Wash, the repair is bigger than the sealant job would have been.
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.

What affects the quote in Enfield Wash
The price is agreed before any work begins. It’s based on:
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
- Access and height
- Any working-time requirements on site
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

DIY sealant or a professional job?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

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. Bigger jobs take longer, and we will say how long yours will take.
When it isn’t the sealant
To be straight with you, some problems need a different trade:
- Crumbling stone or brickwork round the window
- Rotten sashes, sills or window boxes (a joiner’s job)
- Broken panes
Not sure which it is? You can phone 07833 053749 or email us and we’ll tell you honestly before booking.

Related advice
Sand mastic in Enfield Wash: local notes
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Forty Hall (about 1.3 miles west) nearby, there’s older building stock in the area around Enfield Wash as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
For site and facilities teams at buildings such as Eastfield Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Enfield Wash is in London, so parking needs planning: let us know about parking bays, permits or a driveway. Homes close to St George's Church include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Looking after it afterwards
After the cure time, these simple habits help:
- Find out about consent before window work on a listed home
- Ask us before painting near the mastic
- Ask a joiner to look at soft timber first
- Sort the mastic before the decorators arrive
Make sure water drains away from the window surround. Constant wetting wears the mastic faster.
Small cracks are a sign the mastic is ageing. It’s easier to renew it before it drops out.
