How we handle glazing silicone in Charlton

Our work covers conservatory joints, rooflights and glass panels plus shower screens and the bases of glass balustrades. Each joint is cut out, cleaned and resealed. Typical jobs include silicone pulling away from the glass and rooflight joints letting water in, across glass-to-frame joints, shower screens and conservatory frames.

In a smaller place like Charlton, some walls face open ground and catch the full force of the weather. That’s hard on the mastic around frames and sills.

All of our work is guaranteed for twelve months, in Charlton and everywhere else we cover.

What the job involves on each surface

Glass-to-frame joints

We cut the old silicone from the glass without scratching it before new glazing silicone goes in.

Glass-to-glass joints

You see these joints clearly, so a straight, even finish matters.

How we quote for glazing silicone

There’s no set price list, because no two jobs are the same. The quote depends on:

  • The number of rooms or windows
  • How much old sealant there is and how hard it is to remove
  • The number and length of the joints
  • Working hours on commercial sites

Combining jobs into one visit is generally more efficient than separate visits. We’ll give you a clear quote for the lot.

Asking for a quote

To make quoting easier, please include:

  • Whether it has been sealed before
  • Any access issues, like height or stairs
  • How many joints, rooms or windows are involved
  • Pictures of the joints, sent by email

Common questions in Charlton

Is there a guarantee on glazing silicone in Charlton?

All our work, in Charlton and everywhere else, comes with a 12-month guarantee. We’re also fully insured and ARBOMaster approved.

Can you do glazing silicone in Charlton?

Yes, Charlton is within the area we cover. We work across London and the South East. You can phone 0345 464 0079 or drop us an email and let us know what needs doing, and we will send you a clear quote.

What does glazing silicone cost?

Size, access and the old material all affect the cost. Call for a quick quote.

Is it possible to redo the silicone on a shower screen?

Yes. We cut out the old silicone and reseal the glass-to-wall and glass-to-tray joints.

How long should I leave it?

That depends on the sealant used, so follow the cure time we give you.

Can you do several jobs on one visit?

Yes. Several rooms, windows or areas can go on one quote.

Are you ARBOMaster approved?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

Where are you based?

We are based in Crawley, and we work across South East England, London and Scotland.

What happens if it’s left?

Leaks get worse, not better. Water can damage frames, walls, flooring and furniture, so it pays to deal with it early. Homes in smaller places like Charlton can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.

There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or email us.

How it works

There’s no need to move everything out, just the space around the work. We protect the rest, and the work takes a few hours for most jobs for a typical job. In a smaller place like Charlton, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.

  1. First, we check where the water gets in.
  2. We remove the old sealant carefully.
  3. The joint is cleaned and degreased.
  4. A neutral-cure glazing silicone is applied and tooled.
  5. Each joint is checked and, where possible, water-tested.

Preparing for the visit

  • Tell us about access, such as stairs, a lift or high-level joints
  • Try not to wet indoor joints just before the visit
  • Mention if the joints have been sealed before

Advice

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

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.

Frames and glazing around Charlton

Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For site and facilities teams at buildings such as Charlton Primary School, larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Holy Trinity Church, the joint between an old wall and a newer frame is generally the first place rain gets in.

Honest limits

Some problems need a builder, plumber or other trade rather than us:

  • A roof that has moved or dropped
  • Failed flashing around a conservatory
  • Glass that needs replacing

If you are not sure, just phone 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Joints and surfaces we work on

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

Aftercare tips

So the new joints stay in good condition:

  • Clean glass with a mild cleaner and a soft cloth
  • Keep air moving in the conservatory
  • Check the silicone on glass every year or so
  • Wipe the screen down after showering

Follow the cure time we give you before the joints get wet. From then on, a mild glass cleaner is all it needs.

If silicone on glass has cracked, water is already getting in. Resealing now is a small job compared with fixing water damage later.
