How we handle glazing silicone in Selsdon
Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. Typical jobs include drips on the inside of a conservatory window and shower screens leaking along the wall or tray, on shower screens, glass-to-glass joints and glass-to-frame joints. Mr Mastic is a mastic company, not a general handyman, so glazing silicone in Selsdon is done by someone who does this every day.
Many London homes are flats, with windows high above the street. Who looks after the outside of the frames can depend on the lease, so check that first, and access in Selsdon is something to talk through when you book.
We stand behind the work with a one-year guarantee, so you are not left on your own once the job is done.

Windows and doors in Selsdon
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. Historic houses like Addington Palace (about 1 mile north-east) are a reminder that the area around Selsdon 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.
For site and facilities teams at buildings such as Selsdon Primary and Nursery School, the mastic around its windows and doors needs looking after like any other building’s. Rented homes near Sanderstead station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around St Francis, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What happens on the day
There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours, depending on how many joints need doing, including the tidy-up. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.
- We look at the glazing and agree which joints need resealing.
- We cut away the failed silicone.
- The surfaces are cleaned with a suitable solvent.
- New glazing silicone goes in and is finished neatly.
- We inspect the work and test it where we can.
Preparing for the visit
- Clear items away from the joints we are working on
- Let us know about parking restrictions
- Mention any leaks or damp you’ve noticed

Different surfaces, different methods
Rooflights
A rooflight faces rain and sun from above. The sealant around the glass and frame wears faster than most.
Glass balustrade bases
Glass balustrades sit in a channel that is often finished with sealant. Failed sealant there lets water collect.
When something else is needed
We will not take on work that won’t last, so here’s what sealant cannot put right:
- Failed flashing around a conservatory
- Condensation trapped between two panes
- A frame that needs repairing or replacing
Not sure which it is? You can ring 07833 053749 or send us an email and we will tell you honestly.
What we seal
- Conservatory frames
- Glass-to-glass joints
- Glass-to-frame joints
- Shower screens
- Glass balustrade bases
- Rooflights
Aftercare tips
To keep the joints looking good and working properly:
- Look over the glazing joints once a year
- Keep scrapers and blades away from the silicone
- Use a gentle glass cleaner and a soft cloth
- Act on drips or damp patches early
Follow the cure time we give you before the joints get wet. From then on, a mild glass cleaner is all it needs.
Act on black or lifting silicone early. Once it starts to peel, water gets behind it and the problem grows.
Selsdon: your questions answered
Is Selsdon in your area for glazing silicone?
Yes. Our work covers London and the South East, and Selsdon is part of that. You can phone 07833 053749 or email us and let us know what needs doing, and we will send you a clear quote.
Do you work for landlords with property near Sanderstead station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. You can call 07833 053749 or email us with the details for a clear quote.
What do you put in the joint?
It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.
Can you fix a leaking conservatory?
In many cases, as long as sealant is the cause. We find where the water gets in first, so you know what you are paying for.
Will it make a mess?
Not at all. We work neatly, protect the area around the joints and tidy up afterwards.
What guarantee do I get?
Every job comes with our one-year guarantee.
Are you fully insured?
Yes, we’re fully insured for domestic and commercial work.
Do you offer different sealant colours?
Most of the time, yes. We’ll explain which colours are available.
DIY versus a professional finish
If you are set on DIY, put the effort into 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.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Work for landlords, hotels and businesses
We regularly work with letting and managing agents. Tell us the address, the job and how access works.
We work for landlords and letting agents as well as householders. Resealing between tenancies is a simple way to keep a property in good order before the next move-in.

Why it’s worth doing now in Selsdon
Topping up old silicone can look like a fix, but new silicone will not bond to old, and the leak normally returns. A proper reseal is the lasting answer. In a flat in Selsdon, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, phone 07833 053749 or drop us an email and we’ll give you an honest view and a quote.
