Glazing silicone in Copshaw Holm

Glazing silicone in Copshaw Holm, done properly

We do not replace glass and a misted double-glazed unit needs a glazier. What we do is the silicone around the glass and that is often where the water gets in. We’re often asked to deal with rooflight joints letting water in and silicone pulling away from the glass, on shower screens, glass balustrade bases and glass-to-frame joints.

In and around a place like Copshaw Holm, homes range from older stone-built cottages to newer houses. Exposed frames and sills take the full force of wind-driven rain.

Your job is guaranteed for a year, as with all our work.

DIY sealant or a professional job?

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

Leave it or put it right?

Replacing windows or a shower screen isn’t needed for a failed joint. If the glass and frame are sound, new silicone is often all it takes. Exposed walls in smaller Scottish places take a lot of wind and rain, and damp in stone or harled walls takes a long time to dry once water gets behind a joint.

What it costs depends on the size of the job, how hard the old material is to remove and access to the work. You’ll have a clear quote before any work starts, so you know where you stand.

Do you need glazing silicone in Copshaw Holm?

Glass and frames expand and contract with the temperature, and they don’t move by the same amount. In time, the sealant splits or pulls away.

Common reasons people contact us include:

  • Silicone pulling away from the glass
  • Mouldy sealant around glass panels
  • Failed joints on frameless glass
  • Water getting into a conservatory at the joints

In and around Copshaw Holm, as anywhere, good glazing silicone starts with a clean, dry, properly prepared joint.

How to choose a mastic man

The process

On the day, there’s very little for you to do. Point us to the joints and we will get on with it. The work itself takes a few hours for most jobs. Outside jobs in Copshaw Holm need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.

  1. We find where water is getting in and check whether it’s a sealant joint.
  2. Old silicone is cut away from the glass and frame without scratching either.
  3. We clean the joint with a solvent that suits the glass and frame.
  4. We apply a neutral-cure glazing silicone and tool it smooth.
  5. The finished joints are checked and, where it’s safe, tested with water.

Looking after it afterwards

Simple care keeps the joints in good condition. Our advice:

  • Clean glass with a mild cleaner and a soft cloth
  • Keep harsh solvents off the silicone
  • Ventilate the conservatory to cut condensation
  • Avoid scraping close to the bead

Follow the cure time we give you before the joints get wet. After that, clean glass with a mild cleaner.

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

For landlords and businesses

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.

When something else is needed

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

  • Condensation trapped between two panes
  • Failed flashing around a conservatory
  • Cracked or broken glass

If you’re not sure, just drop us a line at info@mrmastic.co.uk and we’ll give you a straight answer.
