Glazing silicone for homes and businesses in Finsbury Park
Glazing silicone that has yellowed, blackened or come away looks poor and can leak. It comes off cleanly, without marking the glass before the new bead goes in. We work on glass-to-frame joints, glass-to-glass joints and shower screens, and the jobs we see most are water getting into a conservatory at the joints and leaks from the base of a shower screen.
London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in, in Finsbury Park as anywhere.

On the day, there’s very little for you to do. Show us the job and we will take it from there. The job generally takes a few hours, depending on how many joints need doing, including the tidy-up. For a job in Finsbury Park, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.
- We trace the leak and confirm it’s a sealant joint.
- We remove the old sealant carefully.
- We clean the glass and frame so the new silicone bonds.
- We lay the new bead and tool it smooth.
- We check the finished joints and test with water where it’s safe.

- Glazing silicone that has cracked or come away
- Water getting into a conservatory at the joints
- Water tracking down the inner face of the glass

Finsbury Park homes and the weather
Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day. In a converted house or block, who looks after the windows depends on the lease, so check that before booking.
Schools such as Stroud Green Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages. Finsbury Park is in London, so parking needs planning: let us know about parking bays, permits or a driveway.

Why it’s worth doing now in Finsbury Park
Resealing cannot fix a failed unit or a cracked panel. We say so plainly, so you can call the right trade. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.
We do not show prices on the website, because the cost depends so much on the job itself. Call for a quick quote and we’ll talk you through it.

Your questions about glazing silicone in Finsbury Park
I let a flat near Finsbury Park station. Can you help?
Yes, we work for landlords and letting agents. You can ring 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.
Do you cover Finsbury Park for glazing silicone?

Are you fully insured?
Yes. Mr Mastic is fully insured, and we’ve been doing sealant work for more than 20 years.
Is balustrade sealant something you do?
Yes. We cut out the failed sealant and reseal the base joint with a suitable product.
How long does the job take?
It depends on the size of the job, but as a guide it takes anything from an hour or two to most of a day, depending on the size of the job. We will give you a better idea when we quote.
Will the old sealant be removed?
Yes, always, and completely. New silicone doesn’t stick to old silicone, so the joint is cleaned back first.

Do I need to be at home?

Aftercare tips
Aftercare is simple:
- Inspect the sealant on glazing annually
- Avoid scraping close to the bead
- Squeegee the shower screen after each use
- Don’t leave a drip for the next storm
Do not use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
Can I do it myself?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
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 doesn’t work out, we can still put it right.
Landlord and commercial work in Finsbury Park
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll give you a quote.
