5 Critical Safety Hazards in Balconies, Walkways, and Terraces That Require Urgent Remediation

Balconies, walkways, and terraces are integral parts of modern residential and commercial buildings, providing outdoor space for occupants. However, due to exposure to the elements and historical building practices, these structures can become contaminated with hazardous materials that pose risks to safety, health, and regulatory compliance.

Understanding which contaminants require urgent remediation is essential for property managers, developers, and landlords. Failing to address these issues can lead to costly repairs, safety hazards, and legal liabilities. Here are the five most pressing contaminants that require immediate attention.

1. Fire-Risk Cladding and Decking Materials

One of the most critical concerns in balcony and walkway construction is the presence of combustible materials. Timber, composite decking, and other flammable materials can contribute to fire spread, making buildings non-compliant with UK fire safety regulations.

Following the Grenfell Tower fire, regulations such as Approved Document B and BS 8579 now require non-combustible materials for balconies and walkways in high-rise buildings. Replacing combustible materials with non-combustible A2 fire-rated aluminium decking is the most effective solution.

2. Corrosion and Structural Deterioration

Balconies and walkways are constantly exposed to rain, humidity, and temperature fluctuations. Over time, steel reinforcements and structural components can corrode, weakening the structure and posing safety risks.

Rusting metal can compromise load-bearing capacity, leading to instability. Upgrading to corrosion-resistant materials, such as powder-coated aluminium decking and subframes, eliminates this risk while offering a longer lifespan and reduced maintenance.

3. Lead-Based Paint and Coatings

Many older buildings feature lead-based paints on balcony railings, soffits, or structural elements. While lead paint was commonly used in construction, its use has been restricted due to health and environmental concerns. Over time, deteriorating coatings can pose a risk, particularly if they begin to flake or degrade.

Although lead exposure is primarily a concern in enclosed spaces or where paint is disturbed, modern regulations require its removal in many cases. Rather than attempting to strip and remediate lead-based coatings, a more effective long-term solution is to remove and replace the entire structure with a non-combustible aluminium system. This ensures compliance with modern building standards while providing a durable, low-maintenance alternative.

4. Algae, Water Damage, and Slip Hazards

Poor drainage and ineffective surface materials can result in water pooling on balconies, walkways, and terraces. Over time, this can lead to structural damage, algae growth, and increased slip hazards, particularly in wet weather.

Choosing decking solutions with integrated drainage channels prevents water accumulation, while anti-slip coatings improve safety. Aluminium decking systems provide superior slip resistance and durability, reducing ongoing maintenance requirements.

5. Asbestos-Containing Materials (ACMs)

Asbestos was widely used in construction before its dangers were fully understood. Some older balconies and terraces may still contain asbestos in soffits, flooring, or insulation materials. When disturbed, asbestos fibres become airborne, creating a severe health risk.

Professional asbestos remediation is necessary to safely remove or encapsulate ACMs. Once removed, installing non-toxic, modern aluminium decking systems ensures compliance with current regulations while eliminating the risk of future contamination.

Proactively addressing contamination in balconies, walkways, and terraces is essential for safety, compliance, and long-term durability. Upgrading to non-combustible, corrosion-resistant aluminium decking helps eliminate fire risks, structural deterioration, and hazardous materials like asbestos and lead-based coatings. Ensuring proper drainage and slip resistance further improves usability and safety.

By choosing modern, fully compliant balcony and walkway solutions, property owners can future-proof their buildings while meeting UK safety and environmental regulations.
