Glazing silicone in Sanderstead
We work across Sanderstead on glazing joints for homes and businesses. From conservatories to shower screens, it’s the same careful method. We work on glass balustrade bases, glass-to-glass joints and rooflights, and the jobs we see most are drips on the inside of a conservatory window and black or yellowed silicone on glass joints.
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 Sanderstead is something to talk through when you book.
We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we will sort it.

Surface by surface
Glass balustrade bases
Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.
Rooflights
Rooflights get the full force of the weather. The sealant around the glass and frame wears faster than most.
Common questions in Sanderstead
Is Sanderstead in your area for glazing silicone?
Yes, Sanderstead is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or email us and tell us what needs doing, and we will give you a clear price.
I let a flat near Riddlesdown station. Can you help?
Yes, landlords and agents are among the people we work for. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all.
Can a conservatory leak be sealed?
In many cases, as long as sealant is the cause. We trace the leak first before any sealing.
What sealant do you use?
Quality sealants from brands including Arbo and Everbuild, picked for each joint. We’ll tell you what we’re using and why.
What guarantee do I get?
Our 12-month guarantee applies on all our work.
Which silicone is used for glass joints?
We use a neutral-cure glazing silicone suited to glass and the frame. In bathrooms, we use anti-fungal silicone.
Do I have to be there?
We need access to the joints, so we will agree that with you when we book. Indoors, that generally means someone at home.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Wipe the screen down after showering
- Keep air moving in the conservatory
- Clear the conservatory gutters regularly
- Check the silicone on glass every year or so
Look over the glazing joints every year or so. Catching a split early keeps the repair small.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple compared with fixing water damage later.
Windows and doors in Sanderstead
The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.
As a London address, Sanderstead can be tricky for parking: let us know about parking bays, permits or a driveway. Schools such as Gresham Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

DIY versus a professional finish
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Work for landlords, hotels and businesses
Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements and we’ll give you a quote.
We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.
What affects the cost of glazing silicone
For a quick quote, just ask. What matters most is:
- How easy the joints are to reach

- Leaks where conservatory glass meets the frame
- Leaking glazing joints on a rooflight
- Leaks from the base of a shower screen
