External mastic near Stirling

About our external mastic in Stirling

On houses, flats and commercial buildings across Stirling, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean, sound faces and a controlled depth. Typical jobs include plants rooting in failed movement joints and movement joints filled with mortar instead of sealant, across render & cladding joints, copings & trims and joints between brick and frames.

In a town like Stirling, older stone-built streets sit alongside newer estates with brick, render and uPVC rooflines. Older buildings tend to leak at gutter joints, newer ones at dried-out movement joints.

All of our work is guaranteed for twelve months, in Stirling and everywhere else we cover.

Can I do it myself?

What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is.

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.

The process

Every visit runs the same way: we look at the joints together, protect the area around them, carry out the job and clear up. It usually takes a few hours for a handful of joints, longer for a whole elevation. For a job in Stirling, tell us where the work is, how to get in and where to park. Outdoor jobs need a dry day, so they can move if the weather turns.

  1. We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
  2. The old mastic and anything lodged in the joint is removed.
  3. The joint faces are cleaned and primed where the sealant needs it.
  4. Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
  5. We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.

Getting ready for the visit

  • Plan for the work area to be out of bounds to pets and children
  • On commercial sites, let us know about site rules
  • Tell us about access, such as stairs, a lift or high-level joints

Landlord and commercial work in Stirling

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.

How the job changes by surface

Joints between dissimilar materials

Each side of the joint may need its own preparation. We prepare both faces so the sealant bonds properly.

Cladding and façade panels

Metal and composite panels move a lot with temperature, so the joints work hard every day. We choose the product to suit.

Common questions in Stirling

Do you cover Stirling for external mastic?

Yes, Stirling 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, and we’ll give you a clear quote.

I let a flat near Stirling station. Can you help?

Yes, we work for landlords and letting agents. Just drop us a line at info@mrmastic.co.uk and tell us about the property, and we’ll give you a clear price.

Can you work on commercial sites?

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

Are you an approved applicator?

Yes. We’re ARBOMaster approved, the scheme for applicators of Arbo sealants.

What information do you need?

Tell us what needs doing and where, plus photos if you have them. We’ll ask anything else we need to know.

Can you quote for more than one area?

Yes. Tell us about everything you’d like done and you will get one quote.

What is backing rod for?

Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.

How do you reach high-level joints?

Each building is different. Tell us the height, the number of joints and what’s below them and we’ll confirm how they can be reached safely.

How we quote for external mastic

Jobs vary more than people expect. What affects the quote:

  • The type of sealant required
  • The number of rooms or windows
  • Any mould that needs treating
  • Working hours on commercial sites

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.

Asking for a quote

What to tell us when you ask for a quote:

  • The address or postcode of the job
  • The rough size of the job
  • Whether it’s a home or a business
  • How we’d reach the joints

There’s no standard price list, because every job is different. Instead, your job gets its own clear quote. To get started, drop us a line at info@mrmastic.co.uk.

Outside joints around Stirling

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 joints where harling meets other materials need a sealant that can grip and flex.

Rented homes near Stirling station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. For an older house near a landmark such as Allan Park South Church, the joints between older walls, newer extensions and the roofline need a sealant that can move.

What sealant work cannot fix

We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:

  • Cracked brickwork or render that needs a builder or plasterer
  • Loose or hollow render, which needs re-rendering
  • Cutting new joints into brickwork, which is building work rather than sealant work

If in doubt, email us at info@mrmastic.co.uk and we will say what we think.

Surfaces we seal

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

What we’re called out for in Stirling

Sunlight, wet weather and frost wear exterior sealant down. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.

If you can see any of these, it’s time to have the joints looked at:

  • Brick movement joints where the sealant has split
  • Rain getting behind render or cladding at a joint
  • Hard, crazed mastic that has stopped moving
  • Leaking joints around cladding and façade panels

Managing a site like Wallace High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Questions to ask before booking

  • What happens if the job turns out different

  • Which sealant they’ll use, and why
  • Whether you can choose the colour
