Glazing Silicone in Swiss Cottage
Glazing joints in Swiss Cottage need attention? We remove the old material, prepare the joints and seal them properly.
- Conservatory leaks at frame and glazing joints
- Black or yellowed silicone on glass joints
- Glazing silicone that has cracked or come away
Glazing silicone for homes and businesses in Swiss Cottage
Sealant on glazing does not last for ever. Weather and movement take their toll and cracked joints let water in. Resealing puts that right. If you have black or yellowed silicone on glass joints and split or lifting silicone on glass, we can help, on conservatory frames, rooflights and glass balustrade bases alike.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or email us.

Aftercare tips
Good habits help new joints last longer. A few tips:
- Use a gentle glass cleaner and a soft cloth
- Do not leave a drip for the next storm
- Check the silicone on glass every year or so
- Wipe the screen down after showering
Follow the cure time we give you before the joints get wet so the silicone can set properly. From then on, a mild glass cleaner is all it needs.
Conservatory leaks rarely stay small. Water travels along the frame and into the wall, so get it looked at when you first see it.
What we are called out for in Swiss Cottage
The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Signs it’s time to call us include:
- Failed joints on frameless glass
- Water escaping where a screen meets the wall
- A quick top-up bead that didn’t last
- Drips on the inside of a conservatory window
For landlords with property near South Hampstead station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.
What to look for in a quote
- Is the old sealant removed completely?
- Whether the sealant suits the joint
- What guarantee comes with the work
- Whether you can choose the colour
Leave it or put it right?
If the problem is a misted unit or a broken panel, sealant will not help. We will tell you that rather than seal it anyway, so you can call the right trade. 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 each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we’ll explain the quote if you ask.
Why us?
- Neat joints and a tidy finish
- Any old sealant cut out fully, not covered over
- An ARBOMaster approved applicator
- Over 20 years’ experience

Glazing silicone in Swiss Cottage: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. Historic houses like Winfield House (about 0.9 miles south-east) are a reminder that the area around Swiss Cottage 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.
As a London address, Swiss Cottage can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as The UCL Academy are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

Surface by surface
Glass balustrade bases
Balustrade bases are exposed outdoors. A sound sealant joint keeps them tidy and dry.
Glass-to-glass joints
Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.

Swiss Cottage questions
Is parking an issue for glazing silicone in Swiss Cottage?
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.
Do you work for landlords with property near South Hampstead station?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before we start.
Can you fix a leaking conservatory?
Yes, when the leak is a failed sealant joint. If it’s a broken panel, failed unit or roof problem, we’ll tell you.
Will the old sealant be removed?
Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can you work on commercial sites?
Yes. Larger jobs can be planned room by room or area by area.
Are you an approved applicator?
Yes. We hold ARBOMaster approved applicator status, and we’re fully insured.
Do you reseal glass shower screens?
Yes. The old bead comes off without marking the glass before cleaning and resealing.
Why not top up the existing silicone?
Many leaks we see come from exactly that. We remove the old silicone, clean the joint and reseal.
How it works
Every visit runs the same way: we check the joints, mask and protect the surrounding surfaces, carry out the job and tidy away. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. For a job in Swiss Cottage, parking and access are the things to plan: let us know about parking, the floor we will be working on and any lift or shared entrance.
- We start by finding the leak and making sure sealant is the cause.
- We cut out the failed silicone, taking care of the glass and frame.
- The glass and frame are cleaned and degreased.
- We apply a neutral-cure glazing silicone and tool it smooth.
- The finished joints are checked and, where it’s safe, tested with water.
Preparing for the visit
- Tell us about access, such as stairs, a lift or high-level joints
- Tell us about any previous sealing or DIY attempts
- Keep pets and children clear of the area while we work
How to get a quote
We quote each job on its own, so start by telling us what you need. Simply ring 0345 464 0079 or drop us an email and describe the job, and pictures are welcome.
Related advice
For landlords and businesses
Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. We can quote for more than one property at once.
Whether it’s one flat or a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a 12-month guarantee.
When something else is needed
To be straight with you, there are a few things sealant will not fix:
- Water coming through the roof rather than a sealant joint
- Glass that needs replacing
- Misting between the panes of a double-glazed unit (a failed unit for a glazier)
Not sure which it is? You can call 0345 464 0079 or email us and we will tell you honestly before booking.
