About our glazing silicone in Northumberland Park
Glazing joints need a sealant made for glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, finished with a neat, even bead. We work on rooflights, glass-to-glass joints and glass balustrade bases, and the jobs we see most are water getting into a conservatory at the joints and sealant that was laid over old silicone and failed.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Northumberland Park is something to talk through when you book.
All our work comes with our 12-month guarantee.

Northumberland Park homes and the weather
London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.
Homes close to St Paul's Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame. For landlords with property near Northumberland Park (London) station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

DIY sealant or a professional job?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
What we cannot put right
Before you book, it’s worth knowing the limits too:
- Condensation trapped between two panes
- Leaks from the roof covering or flashing (a roofer’s job)
- Frames that have decayed or split
If you are not sure, just call 0345 464 0079 or send us an email and we will give you a straight answer.
Joints and surfaces we work on

FAQs for Northumberland Park
Do you work for landlords with property near Northumberland Park (London) station?
Yes, we work for landlords and letting agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is parking a problem for a job in Northumberland Park?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. That way the visit can be planned around it.
What guarantee do I get?
All our work has a one-year guarantee, and we are fully insured.
Does someone need to be in?
Access is agreed with you when the job is booked. Indoors, that generally means someone at home.
Can I add another job to the visit?
Yes. More than one area can go on one quote.
Will there be a smell?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
Do you remove the old sealant?
Yes, every time. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.
Is it enough to run a bead over the old sealant?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Why deal with it now?
You don’t need new glazing because the sealant has gone. If the glass and frame are sound, new silicone is often all it takes. In a London flat, a failed joint rarely stays your problem alone: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.
Leaving a failed joint normally makes the job bigger, not smaller, as water and mould keep getting in. If you are unsure, call 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

Advice
Different surfaces, different methods
Glass balustrade bases
Outdoor balustrade joints face the weather. A sound sealant joint keeps them tidy and dry.
Shower screens
A screen’s wall joint and tray joint are where leaks start. Both are resealed with anti-fungal silicone.
When to call us in Northumberland Park
Sealant laid over old sealant does not last. Many failed joints we see have been topped up rather than cut out leaving a path for water.
People usually contact us when they notice one of these:
- Water getting into a conservatory at the joints
- Sealant that was laid over old silicone and failed
- Failed joints on frameless glass
- Leaking glazing joints on a rooflight
Schools such as Lea Valley Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
What your quote should include
- When the joint can take water or movement
- What product goes in the joint
- How much experience the applicator has
- What guarantee comes with the work
