Book glazing silicone in Charlton

The process

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for most jobs. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. If the building has a concierge, managing agent or access rules, tell us when you book.

  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.

Before we arrive

  • Tell us if parking is tricky
  • Tell us about any previous sealing or DIY attempts
  • Let us know about stairs, lifts or work at height

Glazing silicone in Charlton

Glass and frames expand and contract differently, and the silicone between them takes the strain. When it cracks or lets go, water gets in. We replace it with a glazing silicone that suits the glass and frame. We work on glass-to-glass joints, shower screens and rooflights, and the jobs we see most are new silicone smeared over old sealant and rooflight joints letting water in.

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 Charlton as everywhere else we work.

What the job involves on each surface

Glass-to-frame joints

Silicone at the glass edge seals it into the frame. A failed bead lets water in.

Glass-to-glass joints

These joints are on show, so a straight, even finish matters.

Why it’s worth doing now in Charlton

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. In London conversions, one flat’s bathroom is often above another flat’s ceiling, so a small leak from tired sealant can mean a neighbour’s ceiling and a lot of disruption. Putting it right early is much less trouble for homes in Charlton.

Rather than a set price list, we look at what your job involves: the amount of work, the old material and the access. You’ll know the price before we begin.

Why us?

  • You choose the colour before work begins
  • Neat joints and a tidy finish
  • Anti-fungal silicone where joints get wet
  • Trusted Arbo and Everbuild sealants

Glazing silicone in Charlton: local notes

With historic houses such as Queen's House (about 1.9 miles west) nearby, there’s older building stock in the area around Charlton as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. In London conversions and blocks, the lease decides who is responsible for the frames, so check that before booking.

For landlords with property near Charlton station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. If you look after a building such as Thorntree Primary School, its window and door frames need their mastic kept sound, just like a home’s.

What affects the cost of glazing silicone

The price is agreed before any work begins. It’s based on:

  • When we can work, for business premises
  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • How much there is to do

Doing several joints on one visit is usually more efficient than separate visits. We will give you a clear quote for the lot.

Helping us quote

To make quoting easier, let us know:

  • Whether it has been sealed before
  • Whether it’s a home or a business
  • How many joints, rooms or windows are involved
  • Pictures of the joints, sent by email

If you are in Charlton and need glazing silicone, call 0345 464 0079 or send us an email. Tell us what the problem is and where, and we will agree the price before any work begins.

FAQs for Charlton

Is parking a problem for a job in Charlton?

It can be, so it helps to tell us about permits, visitor bays or off-street space when you book. The visit is then planned around what’s available.

I let a flat near Charlton station. Can you help?

Yes. We work for letting agents and landlords as well as householders. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will send you a clear quote.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

Can you match the sealant colour?

We will suggest a colour to suit the surroundings, from white and clear to greys and other shades. The product needed can limit the range.

What should I tell you?

A short description and the location, plus pictures if you have them. If we need more, we’ll ask.

What sealant do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference, and we will explain our choice.

How long should I leave it?

Most sealants are touch-dry well before they’re fully cured. We’ll give you the cure time for the product we used.

Are you ARBOMaster approved?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.

Do you need glazing silicone in Charlton?

Using a sealant not made for glass causes many failures. Not every silicone sticks properly to glass and vinegar-smelling acetoxy silicone can attack some metals.

Most people get in touch when they notice one of these:

  • Water tracking down the inner face of the glass
  • Leaking glazing joints on a rooflight
  • Shower screens leaking along the wall or tray
  • Water getting into a conservatory at the joints

In the older streets around St Catherine Labouré, the joint between an old wall and a newer frame is generally the first place rain gets in.

When something else is needed

Sealant is not the answer to every problem, and we’ll tell you before work begins. Sealant will not put right:

  • A roof that has moved or dropped
  • Misting between the panes of a double-glazed unit (a failed unit for a glazier)
  • A frame that needs repairing or replacing

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

Joints and surfaces we work on

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

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Clean glass with a mild cleaner and a soft cloth
  • Check the gutters above the glazing for debris
  • Avoid strong solvents on or near the sealant
  • Do not use a blade near the sealant

Clear the conservatory gutters regularly so water does not back up against the seals. Blocked gutters can push water where it shouldn’t go.

Damp patches, drips and condensation along a joint are worth checking. It may be sealant, or something else and we will find out which.
