External mastic for homes and businesses in Kirkpatrick Durham

We’re ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Porous or awkward surfaces are primed where the sealant needs it, and we do not skip that step. If you have old sealant gone brittle and cracked and sealant that has lost its bond to the brick or render, we can help, whatever the surface.

Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. Newer houses need their movement joints and roofline trims kept sound.

You’re covered for a year from the day we finish. If there’s a problem with it, please email us at info@mrmastic.co.uk.

What affects the cost of external mastic

Jobs vary more than people expect. The main factors:

  • Mould in or behind the old joints
  • The old material and how stubborn it is
  • Working hours on commercial sites
  • How easy the joints are to reach

Every job is a little different, so we quote each one individually. Size, access and the product the joint needs all make a difference, and we’ll explain the quote if you ask.

What we need to know

When you contact us, these details help:

  • Photos by email, if that is easy
  • Any previous sealing or DIY work
  • The type of property
  • Where the property is

If you are in Kirkpatrick Durham and need external mastic, email us at info@mrmastic.co.uk. Tell us what the problem is and where, and we’ll agree the price before any work begins.

What we’re called out for in Kirkpatrick Durham

A lot of failed joints come down to preparation: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.

Keep an eye out for these signs:

  • Sealant that has lost its bond to the brick or render
  • Rain getting behind render or cladding at a joint
  • Movement joints with cracked, split or missing sealant
  • Plants rooting in failed movement joints

Around Kirkpatrick Durham, as everywhere, external mastic is only as good as the preparation behind it.

Choosing a sealant specialist

Landlord and commercial work in Kirkpatrick Durham

A neglected joint can let water reach the structure, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance that we can handle for you.

Housing providers, facilities teams and property managers book us too. We can quote a run of properties together, and we’re fully insured.

Keeping the joints in good condition

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

  • Keep high-pressure jets off the joints
  • Ask before painting over external sealant
  • Keep movement joints as flexible joints, not mortar
  • Have failed joints looked at early

Look over the joints once a year, ideally after winter. Watch for splits, edges coming away or growth in the joint.

Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.

Outside joints around Kirkpatrick Durham

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 where harling meets frames, pipes and other materials, the joint needs a flexible sealant that grips a rough surface.

Schools such as Kilquhanity School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

How the visit works

There is not much for you to do on the day. Point us to the joints and we will get on with it. The work itself takes a few hours for a handful of joints, longer for a whole elevation, including the tidy-up. In smaller Scottish places, parking is usually less of an issue than access and distance. Let us know how to find you and how to reach the joints, and the visit is planned around that.

  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.

Preparing for the visit

  • Plan for the work area to be out of bounds to pets and children
  • Mention any leaks or damp you’ve noticed
  • For business premises, tell us about site rules or sign-in

Kirkpatrick Durham: your questions answered

Will you come out to Kirkpatrick Durham?

Yes, we do. Our work covers the whole of Scotland, from towns to the smallest places. Longer journeys are simply planned in advance.

Is external mastic in Kirkpatrick Durham guaranteed?

Every job comes with our 12-month guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

What do you need from me for a quote?

Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.

Can you quote for more than one area?

Yes. More than one area can be quoted together.

Should I point up the gap in my brickwork?

No. Rigid materials cannot move with the wall, so the joint stops doing its job. If it has already been filled, we can usually cut it out and reseal it.

Where are you based?

Mr Mastic is based in Crawley. We cover Kirkpatrick Durham and the rest of Dumfries and Galloway, along with the rest of our area.

How long does external mastic take?

It depends on the size of the job, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We will give you a better idea when we quote.

How long should I leave it?

Cure times vary by product. Before we leave, we will tell you the cure time.

Why act early in Kirkpatrick Durham

Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The wall then cracks somewhere else. A flexible sealant over backing rod is what the joint needs. Around Kirkpatrick Durham, water from a failed joint in an older stone home can soak into timber and plaster, which is a far bigger job than the sealant.

A failed joint rarely gets cheaper to fix by waiting. If you are not sure whether it needs doing, send an email to info@mrmastic.co.uk for an honest opinion and a quote.
