Trusted glazing silicone in Brook Green

What happens on the day

Once we are on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours for most jobs. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.

  1. First, we trace the leak and check it’s coming through a sealant joint.
  2. Old silicone is cut away from the glass and frame without scratching either.
  3. The glass and frame are cleaned and degreased.
  4. New glazing silicone goes in and is tooled to a neat finish.
  5. We check the joints and, where safe, run water over them.

Getting ready for the visit

  • Try not to wet indoor joints just before the visit
  • On commercial sites, let us know about site rules
  • Keep children and pets away from the work area

Glazing silicone in Brook Green

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. Typical jobs include leaks where conservatory glass meets the frame and water tracking down the inner face of the glass, on glass-to-frame joints, rooflights and glass-to-glass joints.

London’s Victorian and Edwardian terraces were built with timber sash windows, and many still have them or their replacements. Whatever is in the opening now, the joint between frame and wall is what keeps the weather out.

Our work is backed for twelve months.

Common problems we fix in Brook Green

The wrong sealant is a common cause. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.

People generally contact us after spotting one of these:

  • Rooflight joints letting water in
  • Water getting into a conservatory at the joints
  • Drips on the inside of a conservatory window
  • Stained, discoloured glazing silicone

If you let a flat or house near Kensington Olympia station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

10 questions to ask before you book

What sealant work cannot fix

Sealant is not the answer to every problem, and we’d rather say so up front. It won’t solve:

  • 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)
  • A roof that has moved or dropped

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

Surfaces we seal

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

What happens if it’s left?

Silicone around glazing needs the right product. A general-purpose tube may not bond well or may react with the frame so we choose a glazing silicone instead. In a flat in Brook Green, failed sealant seldom stays inside your own four walls: water can reach the neighbours below, and gaps in fire-rated joints affect the whole building.

A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

Why Brook Green customers choose us

  • ARBOMaster approved applicator
  • We agree the colour with you first
  • A sealant colour to suit the surroundings
  • Quality sealants from Arbo and Everbuild

Can I do it myself?

A DIY attempt does not rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

Landlord and commercial work in Brook Green

In hotels, rooms out of use cost money, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Housing providers, facilities teams and property managers book us too in Brook Green and across Greater London. Several sites can be quoted together, and we are fully insured for the work.

How the job changes by surface

Conservatory frames

Frame-to-wall joints on a conservatory move with the weather. They’re resealed with a suitable sealant.

Glass-to-glass joints

Where two panes meet, the silicone joint takes all the movement. It must be clean, neat and well bonded.

Frames and glazing around Brook Green

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. With historic houses such as Kelmscott House (about 0.8 miles south-west) nearby, there’s older building stock in the area around Brook Green as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

If you look after a building such as Larmenier & Sacred Heart Catholic Primary School, the mastic around its windows and doors needs looking after like any other building’s. As a London address, Brook Green can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
