External mastic for Portsoy homes and businesses

Work for landlords, hotels and businesses

External mastic in Portsoy

Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where mortar or filler would crack. We work on concrete & block, façade panels and render & cladding joints, and the jobs we see most are movement joints filled with mortar instead of sealant and damp patches traced to an open external joint.

External sealant needs dry surfaces, so outdoor work around Portsoy is planned around the weather. Let us know about access to every wall and roofline.

Every job is covered by a one-year guarantee, wherever you are in Aberdeenshire.

Aftercare tips

To keep the joints looking good and working properly:

  • Make sure movement joints aren’t pointed over
  • Ask before painting over external sealant
  • Point out the joints to other trades
  • Get split or bare joints resealed while the damage is small

Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.

Once a joint can’t move, the wall finds another way, generally as cracking in the brickwork or render nearby. Catch it early and you reduce the risk.

How the job changes by surface

Concrete and blockwork

The face of concrete or block is often dusty, so preparation is key. A primer goes on where the product requires one before the bead.

Cladding and façade panels

Cladding and façade panels are generally separated by sealed joints. Each joint gets a sealant that suits the panel and its movement.

When something else is needed

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

  • Cutting new joints into brickwork, which is building work rather than sealant work
  • Movement that is more than a sealant joint can take
  • Rising or penetrating damp from elsewhere in the wall

If you are not sure, just email us at info@mrmastic.co.uk and we’ll give you a straight answer.

Joints and surfaces we work on

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

What affects the cost of external mastic

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • The type of sealant required
  • How much old sealant there is and how hard it is to remove
  • Working hours on commercial sites
  • How many rooms, windows or areas are involved

Doing several joints on one visit is normally more efficient than separate visits, so it’s worth mentioning everything you’d like done. We’ll give you a clear price for the lot.

What we need to know

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

  • A few pictures by email, if you can
  • What the problem is, such as mould, gaps, leaks or cracking
  • The rough size of the job
  • Whether it’s a home or a business

Want a quote for external mastic? Please email us at info@mrmastic.co.uk and tell us about the job. We’ll explain what we’d do and give you a clear price before we start.

Why deal with it now?

It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Out of town in Scotland, exposed walls take a lot of weather, and once water gets behind a failed joint, damp in stone or harled walls is slow to dry out.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please email us at info@mrmastic.co.uk and we will talk you through it.

Why book with us

  • We agree the colour with you first
  • Anti-fungal sanitary silicone in wet areas
  • Homes, businesses and hotels
  • Any old sealant cut out fully, not covered over

Take a look at what affects the cost and what customers say.

How the visit works

We work through the job in order: protect, prepare, seal, tidy. For most jobs that takes a few hours to a few days, depending on the length of joint and the access. For a place like Portsoy, longer drives are planned in advance. Tell us about tracks, gates, a ferry crossing or anything unusual about getting there.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. Failed sealant is removed back to clean, sound faces.
  3. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. We prime the faces where required.
  5. We gun in low-modulus sealant and tool it neatly.

How to prepare

  • Mention if the joints have been sealed before
  • Tell us if parking is tricky
  • Tell us about any water getting in

Portsoy buildings and the weather

Portsoy is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and sound outside sealant is part of that.

In and around Portsoy, as anywhere, good external mastic starts with a clean, dry, properly prepared joint. In the older streets around St John's Episcopal Church, an extension built onto an older house moves differently, and the joint between them takes the strain.

Portsoy is about 10 miles east of Buckie, in Aberdeenshire. Homes, rented property, offices and hotels in Portsoy is covered for external mastic, old or new, large or small.
