Painting
Protect and refresh your property.
We specialise in high-performance coatings for both interiors and exteriors. From detailed prep work to the final stroke, we take care of every detail — ensuring results that last.
Ideal for:
• Residential homes
• Office blocks and commercial buildings
• High-rise and complex structures (via rope access)
Rope Access
The safest way to reach the hardest places.
When ladders and scaffolding fall short, we rope in the solution. Our trained team handles inspections, painting, repairs, waterproofing and even window cleaning at height — safely and efficiently.
Rope access:
-
Safe and efficient access to hard-to-reach areas
-
Ideal for high-rise waterproofing and maintenance
-
Exterior inspections, cleaning, and repairs without scaffolding
-
Cost-effective alternative to scaffolding and boom lift
-
Certified technicians using IRATA-compliant technique
-
Minimal disruption to building occupants and operations
Maintenance
Proactive care = long-term peace of mind.
Even a perfectly waterproofed roof needs upkeep. UV rays, seasonal wear and debris can cause damage over time. That’s why we offer scheduled maintenance to extend the life of your investment.
We recommend a full inspection every two years. Don’t wait for a rainy day!
Our service includes:
• Visual checks
• Re-coating where needed
• Minor repairs before they become major problems
