Glazing silicone in Newington Green, done properly
Across Newington Green, we reseal glazing joints in homes, offices and hotels. Conservatories, rooflights, glass panels and shower screens are all part of the job, with a sealant chosen for the joint. If you have leaks from the base of a shower screen and drips on the inside of a conservatory window, we can help.
Much of London’s older housing was built with timber sash windows, some still in place and some long since replaced. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.
Every job comes with our 12-month guarantee.

When to call us in Newington Green
Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly the sealant may lift within a few years.
Common reasons people contact us include:
- Silicone pulling away from the glass
- Stained, discoloured glazing silicone
- Failed joints on frameless glass
- Sealant that was laid over old silicone and failed
Schools such as Newington Green Primary School are buildings too, and the mastic around its windows and doors needs looking after like any other building’s.

The process
You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing for a typical job. In Newington Green, flats, stairs and shared entrances are part of the routine. If the building has a concierge, managing agent or access rules, tell us when you book.
- We find where water is getting in and check whether it’s a sealant joint.
- We cut out the failed silicone, taking care of the glass and frame.
- Surfaces are cleaned with a solvent suited to glass and the frame.
- Glazing silicone suited to the joint is applied and tooled.
- We look over every joint and, where we can, test it with water.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Clear items away from the joints we are working on
- Tell us if parking is tricky

Advice
DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it does not work out, we can still put it right.
A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we quote for glazing silicone
The quote reflects the job in front of us. We look at:
- How much old sealant there is and how hard it is to remove
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- Mould in or behind the old joints
What it costs depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
Asking for a quote
Before you ask for a quote, have a think about:
- The problem you’ve noticed
- If someone has resealed it before
- Pictures of the joints, sent by email
- The rough size of the job
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.
Newington Green questions
Is parking a problem for a job in Newington Green?
In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.
Do you cover Newington Green for glazing silicone?
Yes. We work across London and the South East, and Newington Green is part of that. You can ring 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.
Do you remove the old sealant?
Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.
Can a conservatory leak be sealed?
That depends where the water is getting in. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.
Are you an approved applicator?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you offer different sealant colours?
Generally, yes. Sealants come in white, clear, grey and other colours for many products, and we agree the colour with you before any work starts.
How do I get a quote for glazing silicone in Newington Green?
We don’t publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. We agree the price before any work begins.
Can you just put new silicone over the old?
Silicone does not stick to silicone and water gets between the layers. The old bead always comes out first.
Newington Green homes and the weather
With historic houses such as Sutton House (about 1.5 miles east) nearby, there’s older building stock in the area around Newington Green 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.
As a London address, Newington Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. For an older house near a landmark such as Newington Green Unitarian Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why it’s worth doing now in Newington Green
Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Converted houses in London often have a bathroom above someone else’s living room, and a slow leak from a failed seal can end up in the flat below. Putting it right early is much less trouble for homes in Newington Green.
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.

Keeping the joints in good condition
No joint lasts for ever, but care makes a real difference. A few tips:
- Keep harsh solvents off the silicone
- Don’t leave a drip for the next storm
- Stick to mild cleaners on glass
- Run a squeegee over the glass when you’re done
Check the joints once a year. Catching a split early keeps the repair small, before water gets in.
Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.
