Glazing silicone near Merstham

Glazing silicone in Merstham, done properly

Our work covers conservatory joints, rooflights and glass panels, as well as frameless shower screens and glass balustrade bases. The old sealant comes out, the joint is cleaned and new silicone goes in. If you are dealing with water running down inside the glass and failed joints on frameless glass, we can help, on rooflights, glass balustrade bases and shower screens alike.

Somewhere as small as Merstham, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Each job carries a 12-month guarantee.

How the visit works

When we arrive, we start by going over the job with you. We protect the surfaces around the joints before any work starts. The work usually takes a few hours, depending on how many joints need doing. For a village or hamlet like Merstham, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.

  1. We start by finding the leak and making sure sealant is the cause.
  2. We cut out the failed silicone, taking care of the glass and frame.
  3. Surfaces are cleaned with a solvent suited to glass and the frame.
  4. New glazing silicone goes in and is tooled to a neat finish.
  5. The finished joints are checked and, where it’s safe, tested with water.

Preparing for the visit

  • Mention any tricky access
  • Clear the area around the work
  • Mention any sign-in or site rules at work premises

Glass balustrade bases

The base joint is cut out and resealed. Glass fitting is a separate trade.

Merstham: your questions answered

Is Merstham in your area for glazing silicone?

Yes. We work across London and the South East, and Merstham is part of that. Just phone 0345 464 0079 or send us an email with a few details of the job, and we’ll give you a clear quote.

Do you cover smaller places like Merstham?

Yes, Merstham is covered. We work across London and the South East, from towns to the smallest places. The journey is planned ahead, so it helps to know about access.

Why not top up the existing silicone?

It doesn’t last. The new bead can’t grip the old one so we take it all out and start clean.

Can you reseal a frameless shower screen?

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

Which silicone is used for glass joints?

Glass needs a sealant made for glazing. Ours is a neutral-cure glazing silicone and anti-fungal silicone in wet areas.

Are you fully insured?

Yes. We are fully insured.

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 does not work out, we can redo it.

I rent my home. Can I book you?

We can work for tenants, landlords or agents. Just make sure your landlord agrees.

Landlord and commercial work in Merstham

Landlords and letting agents in Merstham can book us as well as householders. Sealant work between tenants is a simple way to keep a property in good order.

In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.

DIY versus a professional finish

A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so just mention it when you contact us.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.

Honest limits

We’ll always be straight with you, so here’s what new sealant will not do:

  • Water coming through the roof rather than a sealant joint
  • Structural problems with a conservatory roof
  • A frame that needs repairing or replacing

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

Joints and surfaces we work on

  • Glass-to-frame joints
  • Shower screens
  • Glass balustrade bases

  • Conservatory frames
  • Glass-to-glass joints

What we’re called out for in Merstham

Using a sealant not made for glass causes many failures. Some products do not bond well to glass and vinegar-smelling acetoxy silicone can attack some metals.

These are the problems we’re asked about most:

  • Cracked silicone between glass panels
  • Water tracking down the inner face of the glass
  • Black or yellowed silicone on glass joints
  • Rooflight joints letting water in

Schools such as Merstham Primary School are buildings too, and larger buildings have plenty of frames, and the mastic around each one ages.

Questions to ask before booking

  • What preparation is included
  • Whether they’re fully insured
  • What product goes in the joint
  • The length of the guarantee

Choosing a sealant specialist

Keeping the joints in good condition

Once the sealant has cured, a few habits help it last:

  • Do not use a blade near the sealant
  • Don’t leave a drip for the next storm
  • Squeegee the shower screen after each use
  • Open vents or windows to let moisture out

Don’t use blades or scrapers near the bead when you clean. A soft cloth or sponge is best.

Drips or damp near a glazing joint shouldn’t be ignored. It may be sealant, or something else and we will find out which.

Merstham 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.

If you let a flat or house near Merstham station, a shower screen or conservatory joint that leaks is easier to reseal while the property is empty. In the older streets around Church of St Katharine, frames set in older brick or stone need a sealant that suits the wall as well as the frame.
