About our glazing silicone in Whitechapel
Cracked, stained or lifting silicone on glass looks poor and can leak. It comes off cleanly, without marking the glass and reseal the joint. If you are dealing with black or yellowed silicone on glass joints and a quick top-up bead that didn’t last, we can help, whatever the surface.
London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.
The work is covered for a year after we finish. If anything isn’t right with it, call 0345 464 0079 or send us an email.

What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. After a quick look at the joints together, we protect the area and start. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In Whitechapel, as in most of London, parking needs a little planning. A visitor permit or a nearby bay makes the visit run more smoothly.
- 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.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- New glazing silicone goes in and is tooled to a neat finish.
- We check the joints and, where safe, run water over them.
Preparing for the visit
- Tell us about any previous sealing or DIY attempts
- Where the joints are inside, avoid wetting them before we arrive
- Mention any leaks or damp you’ve noticed

How the job changes by surface
Glass-to-glass joints
Glass-to-glass joints depend entirely on the sealant. The bead needs to be tidy and fully bonded.
Glass-to-frame joints
The sealant must stick to glass and frame alike. We choose a product that suits both.
Your questions about glazing silicone in Whitechapel
Can parking be tricky for a visit in Whitechapel?
London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.
Can you do glazing silicone in Whitechapel?
Yes, Whitechapel is within the area we cover. Our work covers London and the South East. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear price.
Is there any odour?
Sometimes, a little. It fades as the sealant cures.
Do you have insurance?
Yes. We are fully insured, with over 20 years’ experience in sealant work.
Can I choose the sealant colour?
Yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before any work starts.
Where is Mr Mastic based?
Our base is in Crawley, and we work across South East England, London and Scotland.
Do you guarantee glazing sealant work?
Every job comes with our 12-month guarantee, and we’re fully insured.
Which products do you use?
It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
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.
Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Open vents or windows to let moisture out
- Look over the glazing joints once a year
- Avoid strong solvents on or near the sealant
- Get a new leak looked at quickly
Check the joints once a year. Spotting a crack early means a simpler fix, before water gets in.
Don’t leave lifting or mouldy silicone on glazing. Once it starts to peel, water gets behind it and the leak gets worse.
What sealant work can’t fix
New sealant can’t fix everything, and we’ll tell you before we start. It will not solve:
- Glass that needs replacing
- A sagging or failing conservatory roof
- A sealed unit that has misted inside
If in doubt, ring 0345 464 0079 or send us an email and we will say what we think before you book.

Whitechapel homes and the weather
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. Historic houses like Mansion House (about 0.9 miles west) are a reminder that the area around Whitechapel has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.
Rented homes near Whitechapel station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you look after a building such as Canon Barnett Primary School, the mastic around its windows and doors needs looking after like any other building’s. As a London address, Whitechapel can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
