External mastic near Deaconsbank

External mastic for homes and businesses in Deaconsbank

Low-level joints can normally be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we’ll confirm what’s needed to reach them safely. We work on brickwork movement joints, copings & trims and joints between brick and frames, and the jobs we see most are old sealant gone brittle and cracked and rain getting behind render or cladding at a joint.

Gutters and downpipes on tall city tenements are a long way up, so a leaking joint can run down the stone for months before anyone notices. For a building in Deaconsbank, access is planned first, and shared parts may need the other owners to agree.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Helping us quote

When you call or email, these details help:

  • Any previous sealing or DIY work
  • Where the job is, and your postcode
  • Whether it’s a home or a business
  • Any access issues, like height or stairs

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and add photos by email if you can.

What happens on the day

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 work takes anything from a few hours to several days, depending on the building in most cases. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In Deaconsbank, it helps to know the floor, the door entry arrangements and the nearest parking.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. The old mastic and anything lodged in the joint is removed.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
  5. The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Let us know about stairs, lifts or work at height
  • Try not to wet indoor joints just before the visit

Deaconsbank: your questions answered

Is Deaconsbank in your area for external mastic?

Yes, Deaconsbank is within the area we cover. We work across all of Scotland. You can email us at info@mrmastic.co.uk and tell us what needs doing.

Who arranges sealant work on the shared parts of a tenement in Deaconsbank?

Most tenements arrange shared repairs through the owners or a property factor. The Tenements (Scotland) Act 2004 sets the rules for common parts if the deeds don’t, and we can quote for the factor or the owners directly.

Can tenants book the work?

Yes. Ask your landlord first, and we can send them the quote if that helps.

Do you work for hotels and businesses?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. Working times can be discussed when we quote.

How do you reach high-level joints?

It depends on the building. Tell us the height, the number of joints and what’s below them, and we’ll confirm what access is needed.

Can you match the colour of my brickwork?

The sealant colour is picked to suit the wall so the joint blends in. There’s a wide choice of exterior colours.

Is there any odour?

That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.

Is it OK to fill a movement joint with cement?

No, not if it’s a movement joint. Pointing it stops it working, and the wall may crack nearby. We’ll reseal it with a flexible sealant.

When something else is needed

It helps to know what we can’t do:

  • Cracked brickwork or render that needs a builder or plasterer
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course
  • Cutting new joints into brickwork, which is building work rather than sealant work

If in doubt, send an email to info@mrmastic.co.uk and we will say what we think.

Walls and rooflines in Deaconsbank

Much of Glasgow is built from red and blond sandstone, and sandstone is porous, so any sealant against it has to be one that won’t stain or attack it. Private landlords in Scotland must meet the Repairing Standard, which includes keeping a home wind and watertight, and sound outside sealant is part of that.

Schools such as Eastwood High School are buildings too, and larger buildings have long runs of movement joint that eventually need resealing. Letting a property close to Patterton station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies. Historic houses such as Pollok House, about 2.2 miles north, show how far back building around Deaconsbank goes, and older homes nearby need a sealant that suits their walls.

How to look after the new joints

Looking after new joints is easy:

  • Keep soil, plants and ivy away from the joints
  • Never let anyone fill a movement joint with mortar
  • Wash walls gently around the sealant
  • Ask before painting over external sealant

Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.

An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick.

Surface by surface

Concrete and blockwork

Wide joints in concrete need the depth controlling carefully. Backing rod sized to the joint sets it and keep the sealant to the right depth.

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.

What happens if it’s left?

A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and does not last. Private landlords in Deaconsbank must meet the Repairing Standard, and damp or leaks can fall short of it, so it’s worth fixing failed sealant before a tenant reports it.

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
