Glazing silicone in Brixton
Sealant on glazing does not last for ever. Weather and movement take their toll, and once it cracks, water follows. Resealing puts that right. We work on glass-to-frame joints, rooflights and conservatory frames, and people most often call us about water escaping where a screen meets the wall and drips on the inside of a conservatory window.
From mansion-block windows to modern glazing in new flats, London has every kind of frame. The mastic around them dries out and cracks with age, letting in draughts and water.
Every job comes with our one-year guarantee.

Keeping the joints in good condition
A little care helps the new joints last. We recommend:
- Clean glass with a mild cleaner and a soft cloth
- Ventilate the conservatory to cut condensation
- Keep harsh solvents off the silicone
- Squeegee the shower screen after each use
Follow the cure time we give you before the joints get wet. After that, clean glass with a mild cleaner.
If silicone on glass has cracked, water is already getting in. Renewing it early keeps it simple, compared with repairing damaged frames or plaster.
Why act early in Brixton
A leaking joint won’t fix itself. Water can damage frames, walls, flooring and furniture so early action saves a bigger repair. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re not sure whether it needs doing, ring 0345 464 0079 or email us for an honest opinion and a quote.

Questions from Brixton
Do you work for landlords with property near Brixton station?
Yes. We work for landlords and agents as well as householders. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear quote.
Can you do glazing silicone in Brixton?
Yes. Our work covers London and the South East, and Brixton is part of that. Just phone 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Do you take out the old sealant first?
Yes. We cut out all the old sealant and clean the joint before resealing.
Which products do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll explain our choice.
Is it enough to run a bead over the old sealant?
A top-up rarely holds. Fresh silicone won’t bond to cured silicone so we take it all out and start clean.
Where is Mr Mastic based?
We’re a Crawley-based firm. Our area covers South East England, London and Scotland.
Do I have to be there?
For indoor joints, yes, someone needs to let us in. Once we have agreed the job, you don’t need to watch us work.
Will resealing stop my conservatory leaking?
It depends on the cause. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.
Glazing silicone in Brixton: local notes
In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking. London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
In the older streets around Trinity Congregational Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. Rented homes near Brixton station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

What we do, step by step

In total, it usually takes a few hours, depending on how many joints need doing. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Brixton.

DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
What we are called out for in Brixton
The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.
Any of these means the joints need attention:
- Rooflight joints letting water in
- Cracked silicone between glass panels
- Water tracking down the inner face of the glass
- Glazing silicone that has cracked or come away
As a London address, Brixton can be tricky for parking: let us know about parking bays, permits or a driveway.
