How we quote for external mastic
Jobs vary more than people expect. The main factors:
- The number and length of the joints
- Any working-time requirements on site
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
A few things move the cost up or down: how much old sealant there is and how stubborn it is, any mould to treat, and whether the work is at height. We take all of that into account in your quote.
What we need to know
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Any previous sealing or DIY work
- The type of property
- Roughly how big the job is
- Pictures of the joints, sent by email
We do not publish a price list, because every job is different. Instead, your job gets its own clear quote. To arrange one, email us at info@mrmastic.co.uk.
How we handle external mastic in Kilcreggan
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what’s needed to reach them safely. If you have hard, crazed mastic that has stopped moving and movement joints with cracked, split or missing sealant, we can put it right, whatever the surface.
Older stone buildings need a sealant that suits the stone, not an acetoxy product that can mark or attack it. Newer houses need their movement joints and roofline trims kept sound.
You’re covered for a year from the day we finish. If anything is not right with it, send an email to info@mrmastic.co.uk.

What external mastic looks like in Kilcreggan
Kilcreggan is within about 1 mile of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that.
In the older streets around Craigrownie Parish Church, older walls, gutters and the joints where extensions meet them need a flexible sealant. For landlords with property near Gourock station, outside joints that have cracked can let damp into a rental, so check them between lets.
Kilcreggan is about 4 miles north-west of Greenock, in Argyll and Bute. We provide external mastic to homeowners, landlords and businesses in Kilcreggan and the surrounding area, as part of our work across Argyll and Bute.

The process
A visit follows a simple pattern: we look at the joints together, mask and protect the surrounding surfaces, do the work and clear up. It normally takes a few hours to a few days, depending on the length of joint and the access. Around Kilcreggan, distance and access matter more than parking. Tell us how to find the property and how to reach the work.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- Closed-cell backing rod is fitted to set the depth and stop three-sided bonding.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Mention any sign-in or site rules at work premises
- Clear items away from the joints we are working on

Why it’s worth doing now in Kilcreggan
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 Kilcreggan, water from a failed joint in an older stone home can soak into timber and plaster.
What it costs depends on the amount of work, how hard the old material is to remove and how easy the joints are to reach. We give a clear quote before work begins, so you know where you stand.
What you get with us

Kilcreggan questions
Does living near the coast affect external mastic in Kilcreggan?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
Can you help a landlord with a rental near Gourock station?
Yes, landlords and agents are among the people we work for. You can email us at info@mrmastic.co.uk with the details for a clear quote.
Is there a guarantee?
Yes, always. There’s a 12-month guarantee on every job.
Why is there a gap in my brick wall?
Most straight vertical gaps in brickwork are movement joints. It lets the bricks expand without cracking.
Can I do it myself?
For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. Most DIY failures come from sealing over old material, wet joints or too much sealant.
How long will you be here?
That depends on the amount of work, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll give you a better idea when we quote.

Do you need external mastic in Kilcreggan?
The wrong product in a moving joint is a classic cause. A stiff, general-purpose sealant can’t cope with a joint that moves a lot, so it pulls away from the edges.
The problems people normally mention when they call are:
- Failed seals between different materials
- Movement joints with cracked, split or missing sealant
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
Managing a site like Gourock High School? Then larger buildings have long runs of movement joint that eventually need resealing.

- How the colour is chosen
- Whether all the old sealant comes out first

Keeping the joints in good condition
After the cure time, these simple habits help:
- Check external joints each spring
- Ask before painting over external sealant
- Get split or bare joints resealed while the damage is small
- Fix overflowing gutters above sealed joints
Follow the cure time we give you before the joint is knocked or disturbed. Most exterior sealants skin fast but take longer to cure right through.
Act while the splits are small. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Can I do it myself?
Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
