Glazing silicone in Knightsbridge

Glazing silicone in Knightsbridge, done properly

Across Knightsbridge, we reseal glazing joints in homes, offices and hotels. From conservatories to shower screens, it’s the same careful method. Common call-outs are for shower screens leaking along the wall or tray and water running down inside the glass, on conservatory frames, glass balustrade bases and rooflights.

London has a lot of flats and conversions, where windows are often on upper floors. Who looks after the outside of the frames can depend on the lease, so check that first.

You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

What we’re called out for in Knightsbridge

On shower screens, constant water and cleaning products wear silicone. Mould grows into the bead and the edges begin to peel.

Keep an eye out for these signs:

  • Conservatory leaks at frame and glazing joints
  • Water tracking down the inner face of the glass
  • Water escaping where a screen meets the wall
  • Mouldy sealant around glass panels

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

Questions to ask before you book

  • Whether they’re fully insured
  • How long to leave it before use
  • Whether you can choose the colour
  • How much experience the applicator has

Knightsbridge questions

Can you do glazing silicone in Knightsbridge?

Yes. We work across London and the South East, and Knightsbridge is part of that. You can phone 0345 464 0079 or drop us an email and let us know what needs doing.

Can parking be tricky for a visit in Knightsbridge?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. That way the visit can be planned around it.

Can landlords and businesses book you?

Yes, often. We can quote for several properties at once, and between tenancies is a good time for the work.

What do you need from me for a quote?

Only a few details: the address or postcode, what’s wrong and any access issues. Then call 0345 464 0079 or email us.

How much does glazing silicone cost in Knightsbridge?

Size, access and the old material all affect the cost. Ask us for a quote and we’ll talk you through it.

Should I try DIY first?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

Do you do commercial work?

Yes. We’ve worked for hotels, offices and other businesses and we’re fully insured.

Landlords, agents and businesses in Knightsbridge

Whether it’s one flat or a portfolio, you get the same standard of work: the old material taken out, careful preparation and a 12-month guarantee.

Landlords and letting agents in Knightsbridge can book us as well as householders. Sealant work between tenants keeps a property looking cared for before the next move-in.

The process

At the end, we look at the finished work together and explain the cure time. The work normally takes a few hours for most jobs, depending on the size of the job. Parking in much of London is by permit or pay-and-display, so it helps to know what’s near you in Knightsbridge. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First, we check where the water gets in.
  2. We remove the old sealant carefully.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. We check the finished joints and test with water where it’s safe.

Preparing for the visit

  • Keep pets and children clear of the area while we work
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any leaks or damp you’ve noticed

Advice

Should I try it myself first?

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Surface by surface

Glass balustrade bases

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

Shower screens

Most shower screen leaks come from the wall or tray joint. Both are resealed with anti-fungal silicone.

What affects the cost of glazing silicone

We quote each job individually. This is what makes a difference:

  • Whether old sealant or filler has to be cut out
  • Working hours on commercial sites
  • The number of rooms or windows
  • The size of the job

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and give you a clear price before we start.

Asking for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • The rough size of the job
  • What’s wrong with the joints now
  • Pictures of the joints, sent by email
  • If someone has resealed it before

We do not publish a price list. Instead, your job gets its own clear quote. To get started, ring 0345 464 0079 or send us an email.

Knightsbridge homes and the weather

In London conversions and blocks, the lease decides who is responsible for the frames, so check that before you book. Historic houses like Apsley House (about 0.5 miles east) are a reminder that the area around Knightsbridge has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

In the older streets around Deutsche Evangelische Christuskirche, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Hellenic College of London, the mastic around its windows and doors needs looking after like any other building’s.
