DIY versus a professional finish
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
If you’re set on DIY, put the effort into 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.
Sand mastic in Hale End
A silicone bead around a sash window can look out of place and isn’t always the right material. Sand mastic is the traditional choice, and we can replace one with the other. If you are dealing with patchy fillers round a sash window and mastic worn away on windows facing the weather, we can help, on sash and case windows, stone surrounds and brick reveals alike.
Many London homes are flats, with windows high above the street. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking.
You’re covered for a year from the day we finish. If anything isn’t right with it, call 0345 464 0079 or drop us an email.

What we do, step by step
Most of a good job is in the preparation, and we don’t rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes a few hours for a single window, longer for several. In a London area like Hale End, the main things to plan are parking and access: tell us about permits, visitor bays or off-street space, which floor we are working on and whether there’s a lift.
- We start by checking each surround and agreeing the joints to renew.
- The loose and crumbling mastic is raked out and the joint cleaned.
- We pack any deep gaps so the mastic sits at the right depth.
- We mix the sand mastic and apply it by hand, shaping it to the joint.
- The finish is dressed so it sits neatly against the stone or brick.
Before we arrive
- Mention if the joints have been sealed before
- Mention any parking rules near the property
- Mention any tricky access

Leave it or put it right?
Before painting the windows, it pays to renew the mastic. Painting over failed mastic doesn’t seal it, 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 Hale End, the repair is bigger than the sealant job would have been.
The cost depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins.

Aftercare tips
After the cure time, these simple habits help:
- Check with your local planning authority if your home is listed
- Go gently near the mastic when preparing windows
- Sort the mastic before the decorators arrive
- Ask a joiner to look at soft timber first
Check the mastic when you check the paintwork. Catching cracks early keeps repairs small.
Crumbling mastic lets rain into the joint. It can soak into the frame and the surrounding masonry, so renewing it early is worth it.
Hale End homes and the weather
In a converted house or block, who looks after the windows depends on the lease, so check that before you book. Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Schools such as Joseph Clarke School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. As a London address, Hale End can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Hale End questions
Is parking an issue for sand mastic in Hale End?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
I let a flat near Highams Park station. Can you help?
Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.
What is sand mastic?
It’s a mix of sand and a linseed-oil-based binder. It’s applied by hand and shaped to suit the surround.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
What sealant do you use?
Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.
Can I do it myself?
You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.
Do you offer different sealant colours?
Most of the time, yes. We will explain which colours are available.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
