About our external mastic in Ardrossan
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you are dealing with joints with sealant missing in places and plants rooting in failed movement joints, we can help.
Stone walls need a stone-friendly sealant, as acetoxy products can attack some stone. On newer homes, the movement joints and roofline trims are what need watching.
All of our work is guaranteed for twelve months, in Ardrossan and everywhere else we cover.

What we’re called out for in Ardrossan
Sometimes a movement joint was filled with mortar or a rigid filler, often by someone who didn’t know what it was for. The joint can’t move, so the wall cracks somewhere else instead.
Most people get in touch when they notice one of these:
- Rain getting behind render or cladding at a joint
- Plants rooting in failed movement joints
- Hard, crazed mastic that has stopped moving
- Sealant pulling away from one side of the joint
Rented homes near Ardrossan Town station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Surface by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Tell us what the building has when you get in touch.
Copings and trims
Coping joints that leak let water straight down into the wall. Sealing them early saves the wall below.
How it works
We keep the work tidy and contained to the joints we are treating. Expect the work to take anything from a few hours to several days, depending on the building. Outdoor work around Ardrossan depends on the weather, as sealant needs a dry surface, so an outdoor job can move if the forecast changes. Indoor work goes ahead whatever the weather.
- We start by checking each joint, agreeing the ones to redo and how we’ll reach them.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any parking rules near the property
- Tell us about any previous sealing or DIY attempts
- Mention any leaks or damp you’ve noticed

It all starts with a short chat. Describe the problem, the location and the size of the job, and we will talk you through what we’d do. When it suits you, send an email to info@mrmastic.co.uk.
Advice
DIY versus a professional finish
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
Why act early in Ardrossan
Done well, a resealed joint is a neat, straight line that suits the wall. A rushed bead with no backing looks untidy and does not last. In an older home around Ardrossan, damp from a failed joint can get into timber and plaster.
Rather than a set price list, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

How long does the job take?
That depends on the amount of work, but as a guide it takes a few hours to a few days, depending on the length of joint and the access. We will tell you when we quote.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Sealant is a maintenance item, so check the joints once a year.
Where are you based?

What do you need from me for a quote?
Tell us what needs doing and where, plus photos if you have them. If we need more, we will ask.
Does someone need to be in?
It depends on the job. Inside work needs someone to give us access.
Can a movement joint be filled with mortar?
No, not if it’s a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
Nearby places to Ardrossan

Walls and rooflines in Ardrossan
Ardrossan is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Ardrossan is in the west of Scotland, which is wetter than the east, so there’s plenty of rain for movement joints and outside wall joints to keep out.
Managing a site like Ardrossan Academy? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
How to look after the new joints
To keep the joints looking good and working properly:
- Look over the joints every year, ideally after winter
- Keep soil, plants and ivy away from the joints
- Ask before painting over external sealant
- Have failed joints looked at early
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Leave a failed movement joint and water keeps getting into the wall. Over time it can mean damp inside, stained render or frost-damaged brick which cost more to put right than the joint.
