How to look after the new joints

To keep the joints looking good and working properly:

  • Avoid scraping close to the bead
  • Act on drips or damp patches early
  • Stick to mild cleaners on glass
  • Look over the glazing joints once a year

Gentle products are best near the sealant. Harsh solvents may damage the bead.

Cracked glazing silicone means the joint has failed. Renewing it early keeps it simple compared with fixing water damage later.

About our glazing silicone in Herne Hill

Cracked, stained or lifting silicone on glass spoils the look and lets water in. We remove it without scratching the glass or frame and reseal the joint. If you are dealing with failed joints on frameless glass and failed sealant around rooflight glass, we can put it right, on glass-to-frame joints, rooflights and glass-to-glass joints alike.

London has a lot of flats and conversions, where windows are often on upper floors. In a converted house or block, the lease usually says who is responsible for the windows, so it’s worth checking before booking.

There’s a 12-month guarantee on every job.

Do you need glazing silicone in Herne Hill?

Glass and frames expand and contract with the temperature, and they don’t move by the same amount. In time, the sealant splits or pulls away.

If you can see any of these, it’s time to have the joints looked at:

  • Leaking glazing joints on a rooflight
  • Glass-to-glass joints that have split
  • Shower screens leaking along the wall or tray
  • Split or lifting silicone on glass

If you let a flat or house near North Dulwich station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.

Choosing a sealant specialist

For landlords and businesses

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Failed sealant is one of the commonest items on a check-out report, and it’s easy to sort out between tenants. Several properties can go on one quote.

DIY versus a professional finish

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

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 doesn’t work out, we can still put it right.

What happens if it’s left?

Resealing cannot fix a failed unit or a cracked panel. We’ll tell you that rather than seal it anyway and point you to a glazier or roofer. In older London homes, water behind a failed joint soaks into brick and timber without much sign, and once it shows in Herne Hill, the repair is bigger than a sealant job.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or drop us an email and we will talk you through it.

Herne Hill questions

Can parking be tricky for a visit in Herne Hill?

In much of London, parking needs planning: a visitor permit or a nearby bay makes the day run more smoothly.

Do you work for landlords with property near North Dulwich station?

Yes. We work for letting agents and landlords as well as householders. You can call 0345 464 0079 or send us an email with the details for a clear quote.

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. We use products from Arbo and Everbuild.

Do you replace glass?

No. A misted unit has failed inside, and a glazier needs to replace it.

Which silicone is used for glass joints?

We use a neutral-cure glazing silicone suited to glass and the frame. Shower screens get anti-fungal silicone.

Can you fix a leaking conservatory?

It depends on the cause. Sealant joints we can renew, but roof panels and structural problems need a conservatory specialist or roofer.

Can you quote for more than one area?

Yes, and it often makes sense. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.

Do I have to be there?

It depends on the job. For work indoors, someone needs to let us in.

How we quote for glazing silicone

For a quick quote, just ask. What matters most is:

  • The number and length of the joints
  • The number of rooms or windows
  • Working hours on commercial sites
  • Whether the work is at height

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, call 0345 464 0079 or send us an email and we’ll give you an honest view and a quote.

What we need to know

Photos help, but a description is a good start. Please mention:

  • Where the property is
  • A few pictures by email, if you can
  • The type of property
  • Access, such as stairs, a lift or height

If you’re in Herne Hill and need glazing silicone, phone 0345 464 0079 or drop us an email. Tell us what the problem is and where, and we will agree the price before any work begins.

Windows and doors in Herne Hill

The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. In London conversions and blocks, the lease decides who is responsible for the frames, so it’s worth checking before booking.

If you look after a building such as Judith Kerr Primary School, its window and door frames need their mastic kept sound, just like a home’s. As a London address, Herne Hill can be tricky for parking: let us know about parking bays, permits or a driveway.

The process

A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. Most jobs take anything from an hour or two to most of a day, depending on the size of the job. In Herne Hill, flats, stairs and shared entrances are part of the routine. Mention any building rules, key holders or managing agents when you book.

  1. We look at the glazing and agree which joints need resealing.
  2. Old sealant is removed from the glass and frame.
  3. We clean and prepare the joint.
  4. We apply and tool the new silicone.
  5. The joints are checked before we leave.

How to prepare

  • Mention any leaks or damp you’ve noticed
  • Tell us about any previous sealing or DIY attempts
  • Move anything stored near the joints
