External mastic in Ardgay

How we handle external mastic in Ardgay

A movement joint is a deliberate break that lets a wall expand and contract. Its sealant has to flex with the building, season after season, and when it fails, the wall takes the strain and water finds a way in. If you have weeds or debris growing in open joints and cracked joints where brick meets render or frames, we can help.

Outside joints can only be sealed when they’re dry, so work in Ardgay depends on the weather. Let us know about access to every wall and roofline.

Whatever the size of the job, it’s backed by our 12-month guarantee.

Landlords, agents and businesses in Ardgay

If you manage several properties in or around Ardgay, jobs at different addresses can be quoted together. Send us the addresses and the work at each, and pictures by email help.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.

Honest limits

A few problems are outside what sealant work can do:

  • Render that is blown, hollow or coming away
  • Cracked brickwork or render that needs a builder or plasterer
  • Damp that isn’t coming from the joint

Not sure which it is? You can email us at info@mrmastic.co.uk and we will tell you honestly.

Quotes for external mastic in Ardgay

There’s no set price list, because no two jobs are the same. The quote depends on:

  • How easy the joints are to reach
  • The number and length of the joints
  • Any mould that needs treating
  • Which sealant suits the joint

We do not show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What to tell us for a quote

You do not need to know the technical terms. It helps if you can tell us:

  • Where the property is
  • Whether it has been sealed before
  • Whether it’s a home or a business
  • Pictures of the joints, sent by email

If you’re in Ardgay and need external mastic, send an email to info@mrmastic.co.uk. A short description of the job and where it is helps us quote, and we will agree the price before any work begins.

DIY sealant or a professional job?

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

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Keep high-pressure jets off the joints
  • Check external joints each spring
  • Keep movement joints as flexible joints, not mortar
  • Act on the first splits you see

Follow the cure time we give you before the joint is knocked or disturbed. The surface skins over quickly, but full cure takes longer.

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

What we do, step by step

When we get to you, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. Most jobs then take anything from a few hours to several days, depending on the building. In smaller Scottish places, parking is normally less of an issue than access and distance. Let us know how to find you and how to reach the joints.

  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. Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
  4. Primer is applied wherever the sealant needs it.
  5. A low-modulus exterior sealant is gunned in and tooled to a neat finish.

Getting ready for the visit

Questions from Ardgay

Is external mastic in a coastal place like Ardgay 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.

Is Ardgay within the area you cover?

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.

Do you guarantee your work?

Yes. All our work carries our 12-month guarantee.

Can a movement joint be filled with mortar?

No. Mortar locks the joint solid, so the wall cracks somewhere else instead. It needs a flexible sealant over backing rod.

Can you seal joints between render and window frames?

Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. The colour is chosen to suit.

Where are you based?

We’re based in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

When is the sealant fully cured?

Many sealants skin over quickly but take longer to cure fully. We’ll give you the cure time for the product we used before we leave.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Leave it or put it right?

Running new sealant over the old bead rarely lasts. New sealant does not bond well to old, weathered sealant, so the old joint is cut out fully first. When the nearest tradesperson is a drive away, it’s tempting to leave a small leak, but water through a failed joint keeps working away until it’s fixed.

The cost depends on the amount of work, how much old material has to come out and access to the work. We give a clear quote before work begins.

Walls and rooflines in Ardgay

Ardgay is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. That’s 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.

For landlords with property near Ardgay station, split movement joints are easy to miss on a rental until damp shows inside. In and around Ardgay, as anywhere, good external mastic starts with a clean, dry, properly prepared joint.
