Glazing silicone for homes and businesses in Harringay
Glass, frames and walls all move at different rates, so the sealant between them does a lot of work. Once it splits or comes away, water finds a way through. We replace it with a glazing silicone that suits the glass and frame. We are often asked to deal with mouldy sealant around glass panels and water running down inside the glass, across shower screens, glass-to-frame joints and conservatory frames.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Harringay is something to talk through when you book.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Why act early in Harringay
Dealing with a leaking shower screen early protects the floor and ceiling. A small leak can reach the floor below before you notice. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Every job is a little different, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

DIY sealant or a professional job?
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.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Questions from Harringay
Is Harringay in your area for glazing silicone?
Yes. We work across London and the South East, and Harringay is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is parking an issue for glazing silicone in Harringay?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly, so mention what’s available when you book.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Do the sealants smell?
That depends on the sealant. Some products have a noticeable smell, others very little, and any smell fades as they cure.
Can you work on commercial sites?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
What guarantee do I get?
All our work has a one-year guarantee.
Do you seal glass balustrade bases?
Yes. We cut out the failed sealant and reseal the base joint using a sealant that suits the materials.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone made for wet areas.

Glazing silicone in Harringay: local notes
Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. Historic houses like Bruce Castle (about 1.6 miles north-east) are a reminder that the area around Harringay has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.
As a London address, Harringay can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Letting a property close to Harringay Green Lanes station? Then glazing joints are worth checking at the end of a tenancy, before a small leak grows. If you look after a building such as South Harringay Infant School, larger buildings have plenty of frames, and the mastic around each one ages.

What the job involves on each surface

Most shower screen leaks come from the wall or tray joint. We reseal both with anti-fungal silicone.
