Trusted glazing silicone in Benhilton

Glazing silicone for homes and businesses in Benhilton

Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. Each joint is cut out, cleaned and resealed. If you are dealing with leaks from the base of a shower screen and conservatory leaks at frame and glazing 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. Either way, the mastic between frame and brickwork is what stops draughts and rain getting in.

A 12-month guarantee comes with the work, just as it does everywhere we cover.

When something else is needed

We will always be straight with you, so here’s what sealant cannot fix:

  • Leaks from the roof covering or flashing (a roofer’s job)
  • Misting between the panes of a double-glazed unit (a failed unit for a glazier)
  • Cracked or broken glass

Not sure which it is? You can phone 0345 464 0079 or email us and we’ll tell you honestly.

Surfaces we seal

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

Leave it or put it right?

A new conservatory roof is a big job. If the leak is a failed sealant joint, resealing is far simpler. If it’s the roof itself, we’ll tell you. Damp from a failed joint spreads quietly in older London brickwork and timber, and once it shows in Benhilton, the repair is bigger than a sealant job.

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all play a part, and we’ll explain the quote if you ask.

Why book with us

  • More than 20 years in sealant work
  • Quality sealants from Arbo and Everbuild
  • Old sealant always removed completely
  • Domestic, commercial and hotel work

What we are called out for in Benhilton

Sunlight breaks sealant down, especially on conservatory roofs. It goes brittle, cracks and stops sticking on the glass.

People usually contact us when they notice one of these:

  • Silicone pulling away from the glass
  • Leaking glazing joints on a rooflight
  • Shower screens leaking along the wall or tray
  • Water running down inside the glass

If you live in an older home near All Saints Church, the joint between an old wall and a newer frame is usually the first place rain gets in.

What to look for in a quote

  • When the joint can take water or movement
  • How the surfaces are prepared before sealing
  • How hidden problems are handled
  • How long the guarantee is

Choosing a sealant specialist

DIY sealant or a professional job?

If you’re set on DIY, put the effort into preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it does not work out, we can still put it right.

Too much sealant is as bad as too little. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

What happens on the day

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours, depending on how many joints need doing in most cases. In a London area like Benhilton, the main things to plan are parking and access: let us know about parking, the floor we’ll be working on and any lift or shared entrance.

  1. First we agree the joints to be done.
  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

Advice

Work for landlords, hotels and businesses

Landlords and agents in Benhilton can book us as well as homeowners. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

We also work for property managers and facilities teams in Benhilton and across Greater London. Several sites can go on one quote, and we’re fully insured for the work.

Keeping the joints in good condition

A little care helps the new joints last. We recommend:

  • Do not leave a drip for the next storm
  • Ventilate the conservatory to cut condensation
  • Stick to mild cleaners on glass
  • Don’t use a blade near the sealant

Avoid scraping near the new silicone when cleaning the glass. Stick to a soft cloth.

A small conservatory leak soon spreads. Water runs along frames and down walls, so get it looked at when you first see it.

Frames and glazing around Benhilton

In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

As a London address, Benhilton can be tricky for parking: tell us about permits, visitor bays or off-street space when you book. Rented homes near Sutton Common station change hands often, and a shower screen or conservatory joint that leaks is easier to reseal while the property is empty.
