Glazing silicone for homes and businesses in St Luke's
We don’t replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that’s often where the water gets in. If you’re dealing with cracked silicone between glass panels and silicone pulling away from the glass, we can put it right, whatever the surface.
London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking.
There’s a 12-month guarantee on every job, whatever its size.

Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. We can quote for more than one property at once.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
Windows and doors in St Luke's
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. Historic houses like Mansion House (about 0.8 miles south) are a reminder that the area around St Luke's 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.
Homes close to Jewin Welsh Presbyterian Chapel include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Letting a property close to Old Street station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Jobs for glazing silicone in N1, EC1V and EC2A works the same way as everywhere else we cover. If you need glazing silicone at a property on Long Lane, City Road and Moor Lane or a nearby road, our applicators can take on the job. You’ll find St Luke's on the A1 and A501, so it’s easy for us to get to with everything needed for glazing silicone.

Landmarks near St Luke's

Other local landmarks include St Mary-at-Hill (1.1 miles south), Central Foundation Boys' School (within half a mile east) and Artillery Ground (under half a mile south-east). There’s a railway station in St Luke's itself: Old Street station. A little further out are Gabriel's Wharf (1.3 miles south-west) and Montfichet's Tower (0.9 miles south-west). The countryside around St Luke's includes St. James's Park Lake and Barnsbury Wood.
Why it’s worth doing now in St Luke's
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 London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you’re unsure, phone 0345 464 0079 or email us for an honest opinion and a quote.
Why us?

How it works
On the day, there’s very little for you to do. Point us to the joints and we’ll get on with it. The work itself takes anything from an hour or two to most of a day, depending on the size of the job from start to finish. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Getting ready for the visit
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- Mention any sign-in or site rules at work premises

When to call us in St Luke's
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
If you can see any of these, it’s time to have the joints looked at:
- Sealant that was laid over old silicone and failed
- Water running down inside the glass
- Water getting into a conservatory at the joints
- Black or yellowed silicone on glass joints
Managing a site like St Luke's CofE Primary School? Then the mastic around its windows and doors needs looking after like any other building’s.
Before you book anyone

- How hidden problems are handled
- When the joint can take water or movement
