Greenock West External Mastic

External mastic in Greenock West
Where two different materials meet, such as brick and render or blockwork and metal, they move at different rates. A flexible sealant bridges the two where a rigid filler would soon crack. Common call-outs are for sealant that has lost its bond to the brick or render and weathered mastic that no longer stretches, across brickwork movement joints, joints between brick and frames and render & cladding joints.
In and around a place like Greenock West, many buildings face open ground and take the full weather. Outside joints on exposed walls work hard, so they need a sealant that moves with the building.
Each job carries a 12-month guarantee, large or small.

FAQs for Greenock West
Will you come out to Greenock West?
Yes. Greenock West is within the area we cover, which takes in towns, villages and rural addresses. We work across all of Scotland. Just mention lanes, gates or anything else about the route when you book.
Do you work for landlords with property near Greenock West station?
Yes, we work for landlords and agents. Just send an email to info@mrmastic.co.uk and tell us about the property, and we will give you a clear quote.
Can you match the colour of my brickwork?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Are you ARBOMaster approved?
Yes. We’re an ARBOMaster approved applicator.
How long before the joint can be used?
Different products cure at different speeds, so please follow the time we give you.
Can you reach joints on upper floors?
It depends on the building. Send us pictures and a rough idea of the height and we’ll confirm how they can be reached safely.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Is it messy?
No. We protect the surfaces around the joints, and we clear up the old sealant and our materials before we leave.

Common problems we fix in Greenock West
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and make things worse.
Common reasons people contact us are:
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
Rented homes near Greenock West station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

Aftercare tips
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
- Fix overflowing gutters above sealed joints
- Make sure movement joints aren’t pointed over
Keep pressure washers away from the sealant. High-pressure water can lift the edges over time.
Water getting behind cladding or render can go unnoticed for a long time. By the time there’s a damp patch, the damage can be well established, so it’s worth resealing at the first signs.
Why deal with it now?
A properly done movement joint is an even line in a colour that suits the wall. A rushed bead with no backing looks untidy and doesn’t last, so it pays to do it properly once. Around Greenock West, 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.
Doing several joints on one visit generally makes better use of the time than several visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Sealant is not the answer to every problem, and we will tell you before work begins. It will not solve:
- Cracks in the bricks or render themselves, away from the joints
- Movement that’s more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall

What external mastic looks like in Greenock West

Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather.
