Glazing silicone in Hainault
Conservatory leaks often start at a sealant joint at the glass-to-frame or frame-to-wall joints. We trace the leak to the joint and reseal it, and if it’s something sealant cannot fix, we will tell you. If you have glazing silicone that has cracked or come away and stained, discoloured glazing silicone, we can help. Whether you’re looking for a mastic man, a sealant applicator or a sealant company in Hainault, Mr Mastic can help.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.
A 12-month guarantee comes with the work, just as it does everywhere we cover.

How it works
A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and tidy away. It normally takes anything from an hour or two to most of a day, depending on the size of the job. In Hainault, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- Old silicone is cut away from the glass and frame without scratching either.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We check the joints and, where safe, run water over them.
Before we arrive
- Where the joints are inside, avoid wetting them before we arrive
- Plan for the work area to be out of bounds to pets and children
- On commercial sites, let us know about site rules

Can tenants book the work?

Does someone need to be in?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
Do the sealants smell?
There can be a smell while the sealant cures, but it fades. Opening a window helps.
Common problems we fix in Hainault
New silicone over old silicone will not bond. Plenty of leaks come from a quick top-up over the old bead leaving a path for water.
The problems people usually mention when they call include:
- Shower screens leaking along the wall or tray
- Conservatory leaks at frame and glazing joints
- Water running down inside the glass
- Rooflight joints letting water in
If you let a flat or house near Seven Kings station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
What your quote should include
- Whether the sealant suits the joint
- The length of the guarantee
- How hidden problems are handled
- Whether they seal over old material or remove it
Different surfaces, different methods
Glass-to-frame joints
Where glass sits in a frame, silicone keeps water out. When it splits, water can get into the frame.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
Landlord and commercial work in Hainault
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Failed sealant is one of the commonest items on a check-out report. Several properties can go on one quote.
Windows and doors in Hainault
In a converted house or block, who looks after the windows depends on the lease, so check that before booking. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Limes Farm Junior School? Then the mastic around its windows and doors needs looking after like any other building’s. As a London address, Hainault can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.

Around Hainault

Should I try it myself first?
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.
The biggest DIY mistake is sealing over old sealant. 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.
Why deal with it now?
A quick bead over the old sealant might stop a drip for a while, but new silicone will not bond to old and water soon finds its way back. Cutting out and resealing properly lasts. 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 Hainault, the repair is bigger than the sealant job would have been.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, phone 07833 053749 or send us an email for an honest opinion and a quote.
