What we cannot put right

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

  • Failed render or damaged cladding panels
  • Cracks in the bricks or render themselves, away from the joints
  • Damp from another source, such as a leaking gutter or a bridged damp-proof course

Not sure which it is? You can drop us a line at info@mrmastic.co.uk and we’ll tell you honestly.

Joints and surfaces we work on

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

External mastic in Forres, done properly

Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you have water getting into walls through failed joints and old sealant gone brittle and cracked, we can put it right, on façade panels, brickwork movement joints and render & cladding joints alike.

Scottish weather is hard on outside joints, and a town like Forres gets its share of wind and rain. A gap in a gutter joint, fascia trim or wall joint soon lets damp in.

A one-year guarantee comes with the work, just as it does everywhere we cover.

Common problems we fix in Forres

Some movement joints have been pointed up with mortar by mistake. With the joint locked solid, the movement turns into cracks elsewhere in the wall.

Any of these means the joints need attention:

  • Sealant that has lost its bond to the brick or render
  • Failed seals between different materials
  • Weeds or debris growing in open joints
  • Rigid filler in a joint that should flex

Letting a property close to Forres station? Then split movement joints are easy to miss on a rental until damp shows inside.

Choosing a sealant specialist

Should I try it myself first?

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

What external mastic looks like in Forres

Forres is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.

For an older house near a landmark such as Castlehill Church, an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Andersons Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Your questions about external mastic in Forres

Is external mastic in a coastal place like Forres any different?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Do you cover Forres for external mastic?

Yes. We work across all of Scotland, and Forres is part of that. Just send an email to info@mrmastic.co.uk with a few details of the job.

Why is there a gap in my brick wall?

Brickwork, render and cladding all move a little, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.

Can I add another job to the visit?

Yes, and it often makes sense. Combining jobs makes good use of the visit.

What colours does the sealant come in?

There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so it does not stand out.

Which products do you use?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

Are you an approved applicator?

Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.

Can you work on commercial sites?

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

How to look after the new joints

After the cure time, these simple habits help:

  • Wash walls gently around the sealant
  • Clear growth from the base of walls and joints
  • Point out the joints to other trades
  • Act on the first splits you see

Avoid pressure-washing straight into the joints. A strong jet can damage the edges of the bead over time.

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 which cost more to put right than the joint.

What we do, step by step

We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. Parking around Forres is rarely difficult, though older streets in the centre can be tight. For flats, mention the shared stair or door entry system.

  1. We inspect the joints and agree which need resealing and how they’ll be reached.
  2. We cut out the failed sealant and rake out any dirt or growth.
  3. We clean both faces of the joint and prime them where the product calls for it.
  4. We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
  5. A flexible exterior sealant is applied and tooled in a colour to suit the wall.

Preparing for the visit

  • Clear items away from the joints we are working on
  • Let us know about earlier repairs to the joints
  • Keep children and pets away from the work area
