External & façade joints in Fernhill, South Lanarkshire
Movement joints in Fernhill need attention? We cut out the old, prepare the joints and apply the right sealant.
- Cracked joints where brick meets render or frames
- Panel joints letting water in
- Water getting into walls through failed joints
How the job changes by surface
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
How we handle external mastic in Fernhill
Short cuts in external joints show up within a season or two. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We strip the joint back and start again. Typical jobs include leaking joints around cladding and façade panels and movement joints with cracked, split or missing sealant, on copings & trims, joints between brick and frames and brickwork movement joints.
In and around a place like Fernhill, 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.
A one-year guarantee comes as standard, so you’re not left on your own once the job is done.

Landlord and commercial work in Fernhill
In hotels, rooms out of use cost money, so the work can be planned room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Housing providers, facilities teams and property managers book us too. Several sites can be quoted together, and we are fully insured.
Signs you need external mastic in Fernhill
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
The most common problems we see are:
- Damp patches traced to an open external joint
- Weeds or debris growing in open joints
- Sealant that has lost its bond to the brick or render
- Joints with sealant missing in places
For site and facilities teams at buildings such as Fernhill School, its movement joints, gutters and trims need looking after like any other building’s.
Questions to ask before booking
- What insurance they hold
- What preparation is included
- How the colour is chosen
- Whether they seal over old material or remove it
External mastic in Fernhill: local notes
Under the Repairing Standard, private landlords in Scotland have to keep homes wind and watertight, and failed outside joints work against that. Plenty of Scottish homes have harled walls, and joints where harling meets other materials need a sealant that can grip and flex.
In the older streets around Stonelaw Parish Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Burnside station? Then split movement joints are easy to miss on a rental until damp shows inside.

What happens if it’s left?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, instead of the wall and finishes around it. In a place like Fernhill, small leaks are easy to put off, but water through a failed joint keeps working away until it’s fixed.
Doing several joints on one visit normally makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

The process
You do not need to clear the whole room or building, only the area right around the joints. Everything nearby is protected, and the job takes a few hours for a handful of joints, longer for a whole elevation in most cases. In smaller Scottish places, parking is normally less of an issue than access and distance. Tell us how to find the property and how to reach the work.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Mention any parking rules near the property
- Let us know about earlier repairs to the joints
- Mention any leaks or damp you’ve noticed
Getting a quote
The more we know about the job, the more useful the quote. Tell us where the job is, what’s wrong and how much there is, and email pictures if that’s easy.
Advice
Aftercare tips
Simple care keeps the joints in good condition. Our advice:
- Show decorators and builders where the movement joints are
- Don’t let climbing plants root in the sealant
- Deal with leaking gutters that soak the joints below
- Have failed joints looked at early
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They must stay as flexible joints, never rendered or pointed over.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
