Glazing silicone in Horn Park
Across Horn Park, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. We work on shower screens, glass-to-glass joints and rooflights, and people most often call us about new silicone smeared over old sealant and rooflight joints letting water in.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, which is when draughts and damp patches appear in homes in Horn Park.
Our work is backed for twelve months.

What happens on the day
There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the job takes a few hours, depending on how many joints need doing for a typical job. In Horn Park, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.
- First, we trace the leak and check it’s coming through a sealant joint.
- The old sealant is removed from the glass and frame without scratching them.
- The glass and frame are cleaned and degreased.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Before we arrive
- Let us know about parking restrictions
- For indoor joints, keep the area dry beforehand if you can
- Let us know about earlier repairs to the joints

Common questions in Horn Park
Do you work for landlords with property near Lee station?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or email us with the address and what needs doing, and we’ll send you a clear quote.
Can you do glazing silicone in Horn Park?
Yes. We work across London and the South East, and Horn Park is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we’ll give you a clear quote.
Can you just put new silicone over the old?
Topping up is a common cause of leaks. A proper job means cutting out, cleaning and resealing.
Can you fix a leaking conservatory?
It depends on the cause. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
Do you reseal glass shower screens?
Yes, it’s a common job. We use anti-fungal silicone suited to bathrooms.
Do you replace glass?
We don’t replace glass. We reseal the joints around it, and we will tell you if a unit looks like it has failed.

Can I add another job to the visit?

Different surfaces, different methods
Glass-to-glass joints
You see these joints clearly, so we take care to leave a neat bead.
Rooflights
We reseal the glazing joints on rooflights. Leaks from the roof itself need a roofer.
What we’re called out for in Horn Park
On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the joint starts to lift.
Most people get in touch when they notice one of these:
- Glazing silicone that has cracked or come away
- Black or yellowed silicone on glass joints
- New silicone smeared over old sealant
- Water escaping where a screen meets the wall
For an older house near a landmark such as Church of St Saviour, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

DIY sealant or a professional job?
If you’re set on DIY, put the effort into 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.
The biggest DIY mistake is sealing over old sealant. Silicone doesn’t stick to old silicone, so it lifts and traps water and mould underneath. All the old material has to come out first.
What glazing silicone looks like in Horn Park
With historic houses such as Eltham Palace (about 1 mile east) nearby, there’s older building stock in the area around Horn Park as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
Schools such as Horn Park Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Lee station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
Horn Park is about 1 mile west of Eltham, in Greater London. From the centre of Horn Park to the outskirts, we cover glazing silicone for every kind of property, from flats and houses to offices and hotels. Horn Park is one of 764 towns and villages in Greater London where we work. We also work in London, about 6 miles from Horn Park.

What affects the cost of glazing silicone
There’s no set price list, because no two jobs are the same. The quote depends on:
- The size of the job
- Any mould that needs treating
- How many rooms, windows or areas are involved
- Access and height
Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.
Asking for a quote
Before you ask for a quote, have a think about:
- Any previous sealing or DIY work
- How we’d reach the joints
- The problem you’ve noticed
- Roughly how big the job is
Every job is quoted individually. Just ring 0345 464 0079 or send us an email with the details, and pictures are welcome.
Why act early in Horn Park
Glazing joints need a sealant made for the job. A general-purpose tube may not bond well or may react with the frame, so we use neutral-cure glazing silicone. 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.
Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.

Work for landlords, hotels and businesses
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Resealing at the right time is simple maintenance.
