External mastic for Calderwood homes and businesses

External mastic in Calderwood, done properly

We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing and we use one wherever it does. We work on brickwork movement joints, concrete & block and façade panels, and common reasons people get in touch are failed sealant between panels on a façade and failed seals between different materials.

Across smaller places in Scotland, stone and harled cottages, farm buildings and newer houses often stand exposed to wind and rain. Gutter joints and wall joints take a battering, so they need a sealant that moves with the building.

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

Calderwood buildings and the weather

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. Plenty of Scottish homes have harled walls, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.

Managing a site like Our Lady's High School? Then its movement joints, gutters and trims need looking after like any other building’s. Historic houses such as Howden House, about 2.8 miles west, show how far back building around Calderwood goes, and older homes nearby need a sealant that suits their walls. For landlords with property near Kirknewton station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Should I try it myself first?

A DIY attempt does not rule out a professional job. We cut it out and start again, so just mention it when you contact us.

Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.

When it is not the sealant

Honest advice matters more to us than a booking, so here’s what new sealant will not do:

  • Cracked brickwork or render that needs a builder or plasterer
  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Structural movement, which needs a surveyor or engineer

If you’re not sure, just email us at info@mrmastic.co.uk and we will give you a straight answer before you book.

Where we work in Calderwood

  • Brickwork movement joints
  • Joints between brick and frames
  • Render & cladding joints
  • Façade panels
  • Concrete & block
  • Copings & trims

How to look after the new joints

Joint life depends on how it’s used and looked after. We suggest:

  • Point out the joints to other trades
  • Deal with leaking gutters that soak the joints below
  • Make sure movement joints aren’t pointed over
  • Get split or bare joints resealed while the damage is small

Do not let soil, plants or ivy build up against the new joints. Damp material against the sealant shortens its life.

Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

How we quote for external mastic

Some jobs are bigger than they look, and some smaller. What affects the quote:

  • Any mould that needs treating
  • When we can work, for business premises
  • Which sealant suits the joint
  • How many areas need sealing

The cost depends on the amount of work, how hard the old material is to remove and access to the work. You will have a clear quote before any work starts, so you know where you stand.

Asking for a quote

When you contact us, it’s useful to know:

  • Any previous sealing or DIY work
  • Where the property is
  • The problem you’ve noticed
  • If it’s domestic, commercial or a hotel

Every job is quoted individually. Simply drop us a line at info@mrmastic.co.uk and describe the job.

What happens on the day

When we arrive, we start by going over the job with you, so there are no surprises. We protect the surfaces around the joints before any work begins. The work normally takes a few hours to a few days, depending on the length of joint and the access. Outside jobs in Calderwood need a dry day, because sealant will not bond to a wet joint, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.

  1. We look at every joint and agree a colour to suit the wall.
  2. Failed sealant is removed back to clean, sound faces.
  3. Backing rod goes in so the sealant can stretch between the two faces.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Before we arrive

  • Let us know about stairs, lifts or work at height
  • For business premises, tell us about site rules or sign-in
  • Tell us about any previous sealing or DIY attempts

Advice

What the job involves on each surface

Render joints

Water behind render can lead to blown patches. A sound joint keeps the render dry behind and protects the render itself.

Cladding and façade panels

Where a cladding system has its own specified sealant, we follow it or an approved alternative. Send us any details you have about the façade.

Calderwood: your questions answered

Do you cover Calderwood for external mastic?

Yes, Calderwood is within the area we cover. We work across all of Scotland. Just email us at info@mrmastic.co.uk with a few details of the job.

Do you cover smaller places like Calderwood?

Yes, smaller places are covered as well as towns. Our work covers the whole of Scotland. Just mention lanes, gates or anything else about the route when you book.

When will the joints need doing again?

That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly.

Can you match the colour of my brickwork?

The aim is a neat, even joint in a colour that suits the wall. We will talk through colour options before we start, matched as closely as the range allows.

Do you work for hotels and businesses?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. Working times can be discussed when we quote.

What do you put in the joint?

The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

What is backing rod for?

Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back so the bead can stretch.

What information do you need?

Only a few details: the address or postcode, what’s wrong and any access issues. Then send an email to info@mrmastic.co.uk.

Why deal with it now?

It often makes sense to reseal all the failing joints on an elevation together. Joints of the same age tend to fail together and it means sorting access once. 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.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we’ll go through it with you.

Why book with us

  • Sanitary silicone with an anti-fungal additive in wet areas
  • A choice of colours where the product allows
