Common questions in Auchterarder

Is Auchterarder in your area for external mastic?

Yes. We work across all of Scotland, and Auchterarder is part of that. Just email us at info@mrmastic.co.uk with a few details of the job.

Do you cover smaller places like Auchterarder?

Yes. Auchterarder is within the area we cover, which takes in towns, villages and rural addresses. Our work covers the whole of Scotland. Let us know about access, parking and anything unusual about getting there when you book.

What is a movement joint?

Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. The gap is sealed with a flexible sealant over backing rod.

Can you seal over the old sealant?

No. New silicone will not bond to old silicone, and anything trapped underneath, including mould and water, stays there. It all has to come out first.

I’m a tenant. Can you help?

Yes, though it’s best to check with your landlord first. Many landlords are glad to have it sorted.

Is there any odour?

Possibly a little. It fades as the sealant cures.

Do you use backing rod?

Backing rod goes into deeper joints as a matter of course. It sets the sealant depth and prevents three-sided bonding, so the joint can move.

What do you need from me for a quote?

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

About our external mastic in Auchterarder

Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. The colour is chosen to suit the brick or render so the line blends in. We’re often asked to deal with rigid filler in a joint that should flex and weathered mastic that no longer stretches, across concrete & block, brickwork movement joints and façade panels.

In and around a place like Auchterarder, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard.

Our work is backed for twelve months, and the guarantee is the same wherever you are.

For landlords and businesses

Landlords and letting agents in Auchterarder can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we will give you a quote.

When to call us in Auchterarder

Joints sealed without backing rod, or far too deep, rarely last. If the sealant sticks to the back as well as the sides, it cannot stretch and rips as the joint opens.

These are the problems we’re asked about most:

  • Movement joints with cracked, split or missing sealant
  • Sealant that has lost its bond to the brick or render
  • Rigid filler in a joint that should flex
  • Old sealant gone brittle and cracked

For landlords with property near Gleneagles station, split movement joints are easy to miss on a rental until damp shows inside.

Choosing a sealant specialist

Walls and rooflines in Auchterarder

Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Harled (roughcast) walls are common in Scotland, and where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.

Managing a site like Community School of Auchterarder? Then larger buildings have long runs of movement joint that eventually need resealing. In the older streets around Auchterarder Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant.

Auchterarder is about 12 miles south-west of Perth, in Perth and Kinross.

How it works

We bring everything the job needs with us, so you don’t need to buy or prepare anything. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take anything from a few hours to several days, depending on the building. Outside jobs in Auchterarder need a dry day, because sealant won’t bond to a wet joint, so external jobs may need to move if the day turns wet. Work indoors is not affected.

  1. Each joint is checked and the colour of the new sealant agreed.
  2. We take out the old sealant until the faces are sound.
  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. We gun in low-modulus sealant and tool it neatly.

What affects the cost of external mastic

The price is agreed before any work begins. It takes into account:

  • The type of sealant required
  • How much old sealant there is and how hard it is to remove
  • How easy the joints are to reach
  • Mould in or behind the old joints

Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear quote for the lot.

Helping us quote

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

  • What the problem is, such as mould, gaps, leaks or cracking
  • If someone has resealed it before
  • Pictures of the joints, sent by email
  • Where the property is

Getting a quote is simple: let us know the job and the location. Photos by email help us understand the job, and we’ll take it from there.

Different surfaces, different methods

Brickwork movement joints

Vertical joints in long brick walls let the brickwork expand without cracking. They’re resealed over backing rod with a low-modulus sealant coloured to suit the wall.

Concrete and blockwork

Big joints in concrete need careful depth control. Backing rod sized to the joint sets it and keep the sealant to the right depth.

Why it’s worth doing now in Auchterarder

Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way, and access only has to be arranged once. Exposed walls in smaller Scottish places take a lot of wind and rain, 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 the cost depends so much on the job itself. For a quick quote, please drop us a line at info@mrmastic.co.uk and we will talk you through it.

When something else is needed

To be straight with you, there are a few things sealant won’t fix:

  • Cracking across the wall rather than at a joint
  • Rising or penetrating damp from elsewhere in the wall
  • Loose or hollow render, which needs re-rendering

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