What external mastic looks like in Girvan
Girvan is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That is hard on movement joints and outside wall joints, especially on the side facing the sea. 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.
For landlords with property near Girvan station, split movement joints are easy to miss on a rental until damp shows inside. Homes close to Methodist Church and Halls include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

How we handle external mastic in Girvan
For buildings in Girvan, we reseal external joints of all kinds, from brick movement joints to cladding panels. Every joint gets the same careful preparation: clean, sound faces and a controlled depth. We’re often asked to deal with rain getting behind render or cladding at a joint and moss and dirt in joints with no sealant left, across render & cladding joints, façade panels and copings & trims.
Outside joints can only be sealed when they’re dry, so work in Girvan depends on the weather. Tell us how to reach each wall, gutter and roofline.
Big or small, it’s backed by our 12-month guarantee in Girvan and across South Ayrshire.

What happens on the day
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. Outside jobs in Girvan need a dry day, because sealant will not bond to a wet joint, so external jobs may need to move if the day turns wet. Indoor work goes ahead whatever the weather.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Let us know if you’ve seen damp or leaks
- Mention any tricky access
- Keep children and pets away from the work area

Advice
Honest limits
Some problems need a builder, plumber or other trade rather than us:
- Adding movement joints to masonry that has none
- Failed render or damaged cladding panels
- Damp that isn’t coming from the joint
If in doubt, email us at info@mrmastic.co.uk and we will say what we think.
Surfaces we seal
- Concrete & block
- Façade panels
- Render & cladding joints
- Brickwork movement joints

- Copings & trims
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The wall then cracks somewhere else. The correct repair is a flexible sealant with the right backing. In a place like Girvan, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you’re not sure whether it needs doing, email us at info@mrmastic.co.uk for an honest opinion and a quote.

What affects the quote in Girvan
There’s no set price list. The quote depends on:
- The type of sealant required
- When we can work, for business premises
- The number of rooms or windows
- Mould in or behind the old joints
Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.
What we need to know
There’s no need for technical detail. It helps if you can tell us:
- Any access issues, like height or stairs
- Whether it’s a home or a business
- The rough size of the job
- Where the property is
We quote each job on its own. Simply email us at info@mrmastic.co.uk and describe the job, and pictures are welcome.
Surface by surface
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. We reseal them with an exterior sealant suited to the material.
FAQs for Girvan
Does living near the coast affect external mastic in Girvan?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
I let a flat near Girvan station. Can you help?
Yes. We work for landlords and agents as well as householders, and several properties can go on one quote. Just email us at info@mrmastic.co.uk with the address and what needs doing, and we will give you a clear quote.
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.
Do you use backing rod?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Is it messy?
Not at all. The area is protected while we work and cleaned up afterwards.
Is there any odour?
It depends on the product. Some products have a noticeable smell, others very little.
Do you do commercial work?
Yes. We can plan bigger jobs in stages to suit the site.
What does external mastic cost?
It depends on the job, so we quote each one individually. For a quick quote, email us at info@mrmastic.co.uk and let us know what needs doing and where.
Do you need external mastic in Girvan?
If plants are growing out of a joint, the sealant has generally failed or was never there. Roots and dirt hold water against the wall.
These are the problems we’re asked about most:
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
- Old sealant gone brittle and cracked
For site and facilities teams at buildings such as Girvan Academy, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before booking
- How the joint is cleaned and prepared
- How long the guarantee is
- Whether the sealant suits the joint
- Whether they seal over old material or remove it
