Need glazing silicone in Islington?

DIY sealant or a professional job?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

If you do try it yourself, take your time over the 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.

How we handle glazing silicone in Islington

Glass replacement isn’t something we do, and misting between panes means a failed sealed unit. Our work is the sealant joints and that is often where the water gets in. If you have silicone pulling away from the glass and water getting into a conservatory at the joints, we can put it right, whatever the surface.

Many London homes are flats, with windows high above the street. In a converted house or block, the lease normally says who is responsible for the windows, so it’s worth checking before booking, and access in Islington is something to talk through when you book.

Each job carries a 12-month guarantee, large or small.

Do you need glazing silicone in Islington?

Dirt and grease stop silicone sticking. If the glass and frame weren’t cleaned properly, the bead can peel away early.

Any of these means the joints need attention:

  • Water escaping where a screen meets the wall
  • Water getting into a conservatory at the joints
  • Glass-to-glass joints that have split
  • Water running down inside the glass

As a London address, Islington can be tricky for parking: let us know about parking bays, permits or a driveway.

10 questions to ask before booking

For landlords and businesses

We regularly work with letting and managing agents. Tell us the address, the job and how access works and we’ll quote.

If you manage several properties in or around Islington, jobs at different addresses can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.

When it is not the sealant

It helps to know what we can’t do:

  • Cracked or broken glass
  • Rotten or badly damaged frames
  • Misting between the panes of a double-glazed unit (a failed unit for a glazier)

If in doubt, call 0345 464 0079 or email us and we will say what we think before you book.

Joints and surfaces we work on

  • Shower screens
  • Glass balustrade bases
  • Glass-to-frame joints
  • Conservatory frames
  • Rooflights
  • Glass-to-glass joints

Different surfaces, different methods

Glass-to-glass joints

These joints are on show, so we take care to leave a neat bead.

Glass balustrade bases

Balustrade bases are exposed outdoors. Renewing the sealant keeps water out of the channel.

What we do, step by step

There’s no need to move everything out before we come, just the space around the work. We protect the rest, and the work takes anything from an hour or two to most of a day, depending on the size of the job in most cases. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Islington. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We trace the leak and confirm it’s a sealant joint.
  2. We remove the old sealant carefully.
  3. We clean the glass and frame so the new silicone bonds.
  4. A neutral-cure glazing silicone is applied and tooled.
  5. We check the finished joints and test with water where it’s safe.

Getting ready for the visit

  • Let us know if you’ve seen damp or leaks
  • Try not to wet indoor joints just before the visit
  • Clear items away from the joints we are working on

Advice

Glazing silicone in Islington: local notes

Historic houses like Dr Johnson's House (about 1.6 miles south) are a reminder that the area around Islington has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.

Managing a site like Islington Proprietary School? Then its window and door frames need their mastic kept sound, just like a home’s. For an older house near a landmark such as St Mary's Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Common questions in Islington

Do you cover Islington for glazing silicone?

Yes. We work across London and the South East, and Islington is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will send you a clear quote.

Can you help a landlord with a rental near Essex Road station?

Yes, rental work is part of what we do. You can call 0345 464 0079 or email us with the address and a few details, and we’ll give you a fixed price before we start.

Are you an approved applicator?

Can you quote for more than one area?

Yes. Just list everything you need and you’ll get one quote.

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. After that, simply phone 0345 464 0079 or email us.

What does glazing silicone cost?

It depends on the job, so we quote each one individually. For a quick quote, phone 0345 464 0079 or drop us an email and tell us what needs doing and where.

What do you put in the joint?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

How long before the joint can be used?

It depends on the product and the temperature. Before we leave, we will tell you the cure time.

Why deal with it now?

Resealing cannot fix a failed unit or a cracked panel. We say so plainly and point you to a glazier or roofer. In a flat in Islington, failed sealant seldom stays inside your own four walls: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

The cost depends on the size of the job, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before any work starts, so you know where you stand.
