Advice
How we handle glazing silicone in Lower Holloway
Sealant on glazing doesn’t last for ever. Sun, rain and movement wear it down, and once it cracks, water follows. Resealing puts that right. Common call-outs are for shower screens leaking along the wall or tray and leaks where conservatory glass meets the frame, across conservatory frames, rooflights and glass balustrade bases.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Lower Holloway as anywhere.
Big or small, it’s backed by our one-year guarantee.

DIY versus a professional finish
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not 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: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.
Keeping the joints in good condition
Simple care keeps the joints in good condition. We recommend:
- Wipe the screen down after showering
- Ventilate the conservatory to cut condensation
- Use a gentle glass cleaner and a soft cloth
- Check the gutters above the glazing for debris
Squeegee a shower screen after each shower and keep the room ventilated. It helps stop mould getting into the silicone.
Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else, and we’ll tell you which.
Different surfaces, different methods
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
Common problems we fix in Lower Holloway
Heat and cold make glass and frames move at different rates. Over years, that movement tears the silicone.
Keep an eye out for these signs:
- Mouldy sealant around glass panels
- Water getting into a conservatory at the joints
- Cracked silicone between glass panels
- Shower screens leaking along the wall or tray
Lower Holloway is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.

Quotes for glazing silicone in Lower Holloway
Jobs vary more than people expect. The main factors:
- Mould in or behind the old joints
- How many rooms, windows or areas are involved
- The size of the job
- When we can work, for business premises
Instead of a standard rate, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
Photos help, but a description is a good start. Please mention:
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- A few photos by email, if you can
- If it’s domestic, commercial or a hotel
We do not publish a price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, phone 0345 464 0079 or drop us an email.

What else we do in Lower Holloway
What glazing silicone looks like in Lower Holloway
Historic houses like Witanhurst (about 2 miles north-west) are a reminder that the area around Lower Holloway 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. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
For an older house near a landmark such as St David, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. If you let a flat or house near Caledonian Road & Barnsbury station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

Your questions about glazing silicone in Lower Holloway
Can you do glazing silicone in Lower Holloway?
Yes. We work across London and the South East, and Lower Holloway is part of that. You can ring 0345 464 0079 or send us an email and let us know what needs doing.
Is parking an issue for glazing silicone in Lower Holloway?
It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.
Can a conservatory leak be sealed?
It depends on the cause. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
What do you put in the joint?
The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.
Will it make a mess?
We keep the work tidy. We protect what’s around the joints, and we clear up when we’re done.
Can you work on commercial sites?
Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Is balustrade sealant something you do?
We can. We cut out the failed sealant and reseal the base joint using a sealant that suits the materials.
