Glazing silicone in Richmond upon Thames

Glazing silicone in Richmond upon Thames, done properly

Sealant on glazing does not last for ever. Sun, rain and movement wear it down and cracked joints let water in. Resealing puts that right. We work on shower screens, glass balustrade bases and rooflights, and people most often call us about new silicone smeared over old sealant and black or yellowed silicone on 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.

You get a one-year guarantee, the same in Richmond upon Thames as everywhere else we work.

How the job changes by surface

Glass-to-glass joints

Frameless glass corners and panels are joined with silicone. We reseal with a suitable glazing silicone.

Glass balustrade bases

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

Why it’s worth doing now in Richmond upon Thames

You don’t need new glazing because the sealant has gone. Sound glass and frames normally just need resealing. Converted houses in London often have a bathroom above someone else’s living room, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Dealing with it early is far simpler.

Combining jobs into one visit usually makes better use of the time than several visits. You will get one clear quote for the whole job.

Honest limits

To be straight with you, there are a few things sealant will not fix:

  • Cracked or broken glass
  • Leaks from the roof covering or flashing (a roofer’s job)
  • Condensation trapped between two panes

If you are not sure, just ring 0345 464 0079 or send us an email and we will give you a straight answer.

Joints and surfaces we work on

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

Looking after it afterwards

Aftercare is simple:

  • Ventilate the conservatory to cut condensation
  • Look over the glazing joints once a year
  • Check the gutters above the glazing for debris
  • Keep scrapers and blades away from the silicone

Keep conservatory gutters clear, so water drains away from the joints. Overflowing gutters can cause leaks of their own.

A leaking shower screen may not show at first. Water can soak into the floor or reach the room below before you spot it.

Common questions in Richmond upon Thames

Can parking be tricky for a visit in Richmond upon Thames?

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

Can you do glazing silicone in Richmond upon Thames?

Yes. We work across London and the South East, and Richmond upon Thames is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job.

Can a conservatory leak be sealed?

It depends on the cause. Failed glazing and frame joints can be resealed, but roof panels and structural problems need a conservatory specialist or roofer.

Are you an approved applicator?

Yes. We’re an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Can you quote for more than one area?

Yes. Just list everything you need and you will get one quote.

Do you reseal glass shower screens?

We can. We remove the old silicone carefully, and the joints are cleaned and resealed.

Are you fully insured?

Yes. Full insurance covers our work.

Do you remove the old sealant?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Should I try it myself first?

A DIY attempt does not rule out a professional job. We cut it out and start again.

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Quotes for glazing silicone in Richmond upon Thames

Every job gets its own quote. This is what makes a difference:

  • Whether old sealant or filler has to be cut out
  • The product the joint needs
  • Whether the work is at height
  • Any working-time requirements on site

Some things make a job bigger or smaller: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. We take all of that into account in your quote.

Asking for a quote

To help us quote quickly, please include:

  • Pictures of the joints, sent by email
  • Roughly how big the job is
  • Access, such as stairs, a lift or height
  • Any previous sealing or DIY work

For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. We’ll send you a clear quote before any work starts.

What we do, step by step

Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it normally takes anything from an hour or two to most of a day, 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 Richmond upon Thames. A visitor permit or a nearby bay makes the visit run more smoothly.

  1. First, we check where the water gets in.
  2. The failed silicone is cut out without marking the glass or frame.
  3. We clean the glass and frame so the new silicone bonds.
  4. We lay the new bead and tool it smooth.
  5. Each joint is checked and, where possible, water-tested.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Tell us about any previous sealing or DIY attempts
  • Plan for the work area to be out of bounds to pets and children

Richmond upon Thames homes and the weather

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 Pembroke Lodge (about 1.3 miles south) nearby, there’s older building stock in the area around Richmond upon Thames as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

If you let a flat or house near Richmond station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. For site and facilities teams at buildings such as Marshgate Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Richmond upon Thames is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book.
