Glazing silicone for homes and businesses in Roundshaw
Many conservatory leaks come down to failed sealant at the glass-to-frame or frame-to-wall joints. We find the joint that’s letting water in and renew it, and if it’s something sealant cannot fix, we’ll tell you. If you have leaks where conservatory glass meets the frame and leaks from the base of a shower screen, we can put it right, on conservatory frames, glass-to-frame joints and rooflights alike.
London homes have every kind of window, from timber sashes in period terraces to aluminium and uPVC in newer blocks. The mastic around them dries out and cracks with age, letting in draughts and water.
You’re covered for a year from the day we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

How it works
At the end, we look at the finished work together. The work normally takes a few hours, depending on how many joints need doing, depending on the amount of work. For a job in Roundshaw, parking and access are the things to plan: let us know about parking, the floor we’ll be working on and any lift or shared entrance.
- We trace the leak and confirm it’s a sealant joint.
- The failed silicone is cut out without marking the glass or frame.
- The joint is cleaned and degreased.
- A neutral-cure glazing silicone is applied and tooled.
- We check the finished joints and test with water where it’s safe.
Preparing for the visit
- Try not to wet indoor joints just before the visit
- Mention any sign-in or site rules at work premises
- Mention if the joints have been sealed before

How the job changes by surface
Conservatory frames
Frame joints face sun and rain all year. A fresh bead seals them again.
Shower screens
Black or peeling silicone on a screen lets water out. A full reseal sorts it.
Common problems we fix in Roundshaw
Silicone will not bond to a dirty surface. Where the joint wasn’t cleaned and degreased the sealant may lift within a few years.
It’s worth asking for a quote if you see:
- A quick top-up bead that didn’t last
- Shower screens leaking along the wall or tray
- Water tracking down the inner face of the glass
- Stained, discoloured glazing silicone
Roundshaw is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

What affects the cost of glazing silicone
Jobs vary more than people expect. The main factors:
- The number of rooms or windows
- Mould in or behind the old joints
- Any working-time requirements on site
- The type of sealant required
Doing several joints on one visit is normally more efficient than separate visits, so tell us about everything that needs sealing. You will get one clear quote for the whole job.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- The type of property
- What’s wrong with the joints now
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved

Roundshaw questions
Do you cover Roundshaw for glazing silicone?
Yes, Roundshaw is within the area we cover. We work across London and the South East. Just ring 0345 464 0079 or email us with a few details of the job, and we’ll give you a clear price.
Is parking an issue for glazing silicone in Roundshaw?
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.
Should I try DIY first?
You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.
What do you need from me for a quote?
Only a few details: where it is, what you’ve noticed and how we reach it. Then ring 0345 464 0079 or email us.
Do you seal glass balustrade bases?
We can, if the base joint is sealed. Photos help us see what’s there when you phone 0345 464 0079 or send us an email.
Do the sealants smell?
There can be a smell while the sealant cures. Ventilation helps.
Can you match the sealant colour?
We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The choice depends on the product the joint needs.
Do you replace glass?
Glass replacement is not our trade. We reseal the joints around it, and we’ll tell you if a unit looks like it has failed.
Honest limits
To be straight with you, some problems need a different trade:
- A sealed unit that has misted inside
- Structural problems with a conservatory roof
- Leaks from the roof covering or flashing (a roofer’s job)
Not sure which it is? You can phone 0345 464 0079 or email us and we will tell you honestly.
What we seal
- Rooflights
- Conservatory frames
- Glass-to-frame joints
- Glass-to-glass joints
- Glass balustrade bases
- Shower screens

What else we do in Roundshaw
DIY versus a professional finish
Sealing over old silicone is the commonest DIY error. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.
Roundshaw homes and the weather
With historic houses such as Addington Palace (about 3.9 miles east) nearby, there’s older building stock in the area around Roundshaw as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.
Schools such as Wallington Primary Academy are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you let a flat or house near Wallington station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
