About our glazing silicone in Brockley Hill
Not every silicone suits glass. Our applicators use neutral-cure glazing silicone that is suited to glass and the frame, and we tool it to a neat, even finish. Common call-outs are for a quick top-up bead that didn’t last and glass-to-glass joints that have split, on glass balustrade bases, glass-to-glass joints and glass-to-frame joints.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease generally says who is responsible for the windows, so it’s worth checking before booking.
All of our work is guaranteed for twelve months, in Brockley Hill and everywhere else we cover.

Common problems we fix in Brockley Hill
Dirt and grease stop silicone sticking. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
Keep an eye out for these signs:
- Water getting into a conservatory at the joints
- Mouldy sealant around glass panels
- Shower screens leaking along the wall or tray
- Drips on the inside of a conservatory window
If you let a flat or house near Elstree & Borehamwood station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Brockley Hill: your questions answered

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Is Brockley Hill in your area for glazing silicone?
Yes. Our work covers London and the South East, and Brockley Hill is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we’ll send you a clear quote.
Do you have insurance?

Do the sealants smell?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Do you hold any approvals?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
What information do you need?
Just the basics: the address or postcode, what’s wrong and any access issues. Then phone 0345 464 0079 or send us an email.
Do I need to be at home?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we will agree access with you when we book.
For landlords and businesses
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

The process
Most of a good job is in the preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours, depending on how many joints need doing. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- We clean the joint with a solvent that suits the glass and frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Preparing for the visit
- Mention any tricky access
- Clear the area around the work
- Tell us if parking is tricky
How to get a quote
Getting a quote is simple: let us know what needs doing and where, and roughly how big it is. A few pictures by email make the job easier to understand, and we’ll take it from there.

Glazing silicone in Brockley Hill: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. With historic houses such as Headstone Manor (about 3.4 miles south-west) nearby, there’s older building stock in the area around Brockley Hill as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
In the older streets around St Peter, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as London Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Sealing over old silicone is the commonest DIY error. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What the job involves on each surface
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Glass-to-frame joints
Old sealant is removed carefully from the glass before new glazing silicone goes in.
