Glazing & conservatory sealant in Turnpike Lane, Greater London
Professional glazing silicone in and around Turnpike Lane, with old sealant always removed completely and a 12-month guarantee.
- Sealant that was laid over old silicone and failed
- Water running down inside the glass
- Cracked silicone between glass panels
What we’re called out for in Turnpike Lane
New silicone over old silicone will not bond. Many failed joints we see have been topped up rather than cut out, and water gets between the layers.
Any of these means the joints need attention:
- Mouldy sealant around glass panels
- Cracked silicone between glass panels
- Glazing silicone that has cracked or come away
- Drips on the inside of a conservatory window
In the older streets around Church of St John The Baptist (greek Orthodox), the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.
What your quote should include
- The length of the guarantee
- What happens if they find a problem under the old sealant
- What preparation is included
- Whether they seal over old material or remove it
About our glazing silicone in Turnpike Lane
Glass replacement is not something we do and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. We work on glass-to-frame joints, glass balustrade bases and glass-to-glass joints, and common reasons people get in touch are leaks from the base of a shower screen and failed joints on frameless glass.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
All our work comes with a one-year guarantee.

How to look after the new joints
No joint lasts for ever, but care makes a real difference. Our tips:
- Clear the conservatory gutters regularly
- Use gentle products around the joints
- Keep scrapers and blades away from the silicone
- Inspect the sealant on glazing annually
Clear the conservatory gutters regularly, so water drains away from the joints. Blocked gutters can push water where it shouldn’t go.
A small conservatory leak soon spreads. Water travels along the frame and into the wall, so get it looked at when you first see it.

Your questions about glazing silicone in Turnpike Lane
I let a flat near Hornsey station. Can you help?

Where are you based?
Mr Mastic is based in Crawley. We cover Turnpike Lane and the rest of Greater London.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, and for outside work we’ll agree access with you when we book.
Can I add another job to the visit?
Yes. Just list everything you need and we will quote it together.
Do you work for hotels and businesses?
Yes. We can plan bigger jobs in stages.
Can you fix a leaking conservatory?
That depends where the water is getting in. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Are you an approved applicator?
Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.
How the job changes by surface
Glass balustrade bases
The base of a glass balustrade is usually sealed. Failed sealant there lets water collect.
Rooflights
Rooflight glazing joints are cut out and renewed. If the leak is from the roof around it, a roofer needs to look.
Why act early in Turnpike Lane
Dealing with a leaking shower screen early protects the floor and ceiling. Water from a failed joint can soak into the floor before it shows. In a flat in Turnpike Lane, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Doing several joints on one visit normally makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Windows and doors in Turnpike Lane
In a converted house or block, who looks after the windows depends on the lease, so it’s worth checking before booking. Historic houses like Bruce Castle (about 1.5 miles north-east) are a reminder that the area around Turnpike Lane has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.
As a London address, Turnpike Lane can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Hornsey station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows.

DIY versus a professional finish
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
