Glazing silicone for homes and businesses in Colston

Not every silicone suits glass. Our applicators use neutral-cure glazing silicone, which suits glass and most frame materials, and we tool it to a neat, even finish. If you have new silicone smeared over old sealant and water escaping where a screen meets the wall, we can help, on glass balustrade bases, glass-to-glass joints and rooflights alike.

Tenement flats in Scotland’s cities often have windows high above the street, so the mastic outside can go unchecked for years. Access is the first thing to plan for a job in Colston.

Whatever the size of the job, you get the same 12-month guarantee in Colston and across Glasgow.

What happens if it’s left?

If the problem is a misted unit or a broken panel, sealant will not help. We say so plainly and point you to a glazier or roofer. Wind-driven rain gets into any failed joint on the outside of a city building, and in Colston, damp can spread through stone and plaster before anyone sees it.

A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether the work is at height. We take all of that into account in your quote.

What the job involves on each surface

Conservatory frames

Leaks often start where the frame meets the wall. We cut out the old sealant and reseal.

Shower screens

A screen’s wall joint and tray joint are where leaks start. We reseal both with anti-fungal silicone.

How we quote for glazing silicone

There’s no set price list, because jobs vary so much. What we look at:

  • The size of the job
  • The product the joint needs
  • How many areas need sealing
  • How much old sealant there is and how hard it is to remove

No two jobs are quite the same, so each one gets its own quote. Size, access and the product the joint needs all make a difference.

Helping us quote

The more you tell us, the more accurate the quote. When you ask for a quote, tell us:

  • Any access issues, like height or stairs
  • Where the property is
  • Whether it’s a home or a business

There’s no standard price list, as no two jobs are quite the same. Instead, your job gets its own clear quote. To arrange one, send an email to info@mrmastic.co.uk.

When something else is needed

It helps to know what we can’t do too:

  • A broken pane or roof panel
  • A sealed unit that has misted inside
  • Failed flashing around a conservatory

Not sure which it is? You can email us at info@mrmastic.co.uk and we’ll tell you honestly before booking.

Frames and glazing around Colston

The west of Scotland is wetter than the east, which means glazing joints and frame seals has to cope with a lot of rain. The Tenements (Scotland) Act 2004 sets out how owners share the upkeep of common parts like the roof and outside walls, and many buildings use a factor to arrange it. Windows generally belong to the flat, but the title deeds have the final say.

For site and facilities teams at buildings such as Bishopbriggs Academy, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near Colston Wellpark Church, the joint between an old wall and a newer frame is normally the first place rain gets in.

Common problems we fix in Colston

UV light ages silicone and roof joints get the most sun. It goes brittle, cracks and stops sticking to the glass and frame.

Common reasons people contact us include:

  • Leaks from the base of a shower screen
  • Black or yellowed silicone on glass joints
  • Conservatory leaks at frame and glazing joints
  • A quick top-up bead that didn’t last

For landlords with property near Bishopbriggs station, leaking glazing joints, shower screens or conservatory seals are worth sorting between tenancies.

What to look for in a quote

  • How long to leave it before use
  • What happens if they find a problem under the old sealant
  • Whether all the old sealant comes out first
  • Who does the work, and how experienced they are

How to choose a mastic man

DIY versus a professional finish

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. Everything old must be removed first.

Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.

The process

You do not need to clear the whole room or building before we come, just the space around the work. Everything nearby is protected, and the job takes anything from an hour or two to most of a day, depending on the size of the job for a typical job. In a city area like Colston, parking may be by permit or pay-and-display, so tell us what’s nearby. For flats, mention the door entry system and any shared-stair arrangements.

  1. We look at the glazing and agree which joints need resealing.
  2. Old sealant is removed from the glass and frame.
  3. The surfaces are cleaned with a suitable solvent.
  4. New glazing silicone goes in and is finished neatly.
  5. We inspect the work and test it where we can.

Before we arrive

  • Keep children and pets away from the work area
  • On commercial sites, let us know about site rules
  • Let us know if you’ve seen damp or leaks

Common questions in Colston

How is work on the outside of a tenement in Colston usually arranged?

It usually goes through the owners together, or through the factor if the building has one. The Tenements (Scotland) Act 2004 covers the common parts where the deeds don’t, and we can quote for the factor or the owners directly.

Is Colston in your area for glazing silicone?

Yes. We work across all of Scotland, and Colston is part of that. You can email us at info@mrmastic.co.uk and tell us what needs doing, and we’ll give you a clear price.

Can you do several jobs on one visit?

Yes. Tell us about everything you’d like done and we’ll quote it together.

What information do you need?

Only a few details: where it is, what you’ve noticed and how we reach it. After that, simply send an email to info@mrmastic.co.uk.

Why not top up the existing silicone?

A top-up rarely holds. Fresh silicone will not bond to cured silicone so we take it all out and start clean.

Do you seal glass balustrade bases?

Yes. The old sealant is removed and the joint resealed with a suitable product.

Do you work for landlords and businesses?

Yes. As well as homeowners, we work for landlords, agents, businesses and hotels in Colston.

How long does glazing silicone take?

A typical job takes a few hours for most jobs, including preparation and clearing up. We will confirm how long when we quote.
