Glazing silicone for homes and businesses in Newington Butts

Glazing joints need a sealant made for glass. We use a neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you are dealing with sealant that was laid over old silicone and failed and black or yellowed silicone on glass joints, we can put it right.

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.

We stand behind the work with a one-year guarantee, so you’re not left on your own once the job is done.

When something else is needed

We won’t take on work that won’t last, so these are the limits:

  • A roof that has moved or dropped
  • Failed flashing around a conservatory
  • Rotten or badly damaged frames

If you’re not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

What we seal

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

What the job involves on each surface

Glass-to-glass joints

Where two panes meet, the silicone joint takes all the movement. The bead needs to be tidy and fully bonded.

Glass balustrade bases

The base of a glass balustrade is generally sealed. When it fails, water can sit in the channel.

Can I do it myself?

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

If you’ve already had a go yourself, that is fine. We cut it out and start again, so tell us about it when you ask for a quote.

What happens on the day

We keep the work tidy and contained to the area we are working on, so you can carry on as normal. The job usually takes a few hours, depending on how many joints need doing, and we explain the cure time before we leave. In Newington Butts, as in most of London, parking needs a little planning. It helps if you can point us to a visitor permit or a bay close to the door.

  1. We look at the glazing and agree which joints need resealing.
  2. Old sealant is removed from the glass and frame.
  3. The surfaces are cleaned with a suitable solvent.
  4. We apply and tool the new silicone.
  5. We inspect the work and test it where we can.

Getting ready for the visit

  • Keep pets and children clear of the area while we work
  • Tell us about any previous sealing or DIY attempts
  • Tell us about any water getting in

Advice

Landlords, agents and businesses in Newington Butts

For anyone letting property in or around Newington Butts, several properties can be quoted together. Just tell us the addresses and what each one needs, and pictures by email help.

Your questions about glazing silicone in Newington Butts

Can you help a landlord with a rental near Elephant & Castle 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’ll give you a clear quote.

Do you cover Newington Butts for glazing silicone?

Yes, Newington Butts is within the area we cover. Our work covers London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we will send you a clear quote.

Is there any odour?

It depends on the product. Some smell for a while, some hardly at all, and any smell fades as they cure.

Can you fix a leaking conservatory?

It depends on the cause. Failed glazing and frame joints can be resealed but roof and panel problems need another trade.

Why not top up the existing silicone?

New silicone will not bond to old silicone and water gets between the layers. We cut out the old sealant first.

Can you do several jobs on one visit?

Yes. Just list everything you need and we’ll quote it together.

How long does the job take?

A typical job takes anything from an hour or two to most of a day, depending on the size of the job, including the preparation. Your quote will say how long we expect yours to take.

How much does glazing silicone cost in Newington Butts?

The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.

Aftercare tips

How long the joints last depends on use and care. We suggest:

  • Squeegee the shower screen after each use
  • Avoid scraping close to the bead
  • Open vents or windows to let moisture out
  • Keep harsh solvents off the silicone

Don’t use blades or scrapers near the bead when cleaning the glass. A soft cloth or sponge is best.

Drips or damp near a glazing joint shouldn’t be ignored. The cause may be sealant or another part and we’ll find out which.

Why act early in Newington Butts

A leaking joint will not fix itself. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. 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.

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all play a part.

What glazing silicone looks like in Newington Butts

Historic houses like Benjamin Franklin House (about 1.4 miles north-west) are a reminder that the area around Newington Butts has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book.

Letting a property close to Elephant & Castle station? Then a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around Metropolitan Tabernacle, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Schools such as London College of Communication are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
