External mastic across East Renfrewshire: what to expect
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on copings & trims, render & cladding joints and façade panels, and the jobs we see most are rigid filler in a joint that should flex and water getting into walls through failed joints.
All our tools and materials come with us in the van. Once we’ve agreed what’s being done, the area is protected and the work begins. Most jobs take a few hours for a handful of joints, longer for a whole elevation.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.

Newton Mearns: Historic houses such as Pollok House, about 3.7 miles north, show how far back building around Newton Mearns goes, and older homes nearby need a sealant that suits their walls. For site and facilities teams at buildings such as Mearns Castle High School, its movement joints, gutters and trims need looking after like any other building’s.
When it isn’t the sealant
We will always be straight with you, so here’s what new sealant will not do:
- Movement that’s more than a sealant joint can take
- Loose or hollow render, which needs re-rendering
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
DIY versus a professional finish
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.
Landlords, agents and businesses in East Renfrewshire
A neglected joint can let water reach the structure, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Surface by surface
Cladding and façade panels
If the façade has a specified sealant, that’s what we use, or one the system allows. Send us any details you have about the façade.
Concrete and blockwork
Concrete faces can be dusty and porous, so cleaning and priming matter. We prime where the sealant needs it.
What we are called out for in East Renfrewshire
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.
If you can see any of these, it’s time to have the joints looked at:
- Weathered mastic that no longer stretches
- Movement joints with cracked, split or missing sealant
- Rain getting behind render or cladding at a joint
- Weeds or debris growing in open joints
East Renfrewshire questions
How long does external mastic take?
As a guide, most jobs take a few hours to a few days, depending on the length of joint and the access. Bigger jobs take longer.
Will you leave a mess?
No. The area is protected while we work and cleaned up afterwards.
Why do you put foam in the joint first?
Backing rod goes into deeper joints as a matter of course. It controls the depth and stops the sealant bonding to the back.
What information do you need?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Do you work for landlords and businesses?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Will the old sealant be removed?
Yes. All of the old material is cut out and the joint cleaned before applying anything new.
