A lot of external wall insulation went on with 25-year insurance-backed guarantees. What gets missed is the maintenance those guarantees need. We inspect, clean and repair the systems so they stay weathertight, looking right, and compliant.
Over the past 10 years, many external wall insulation projects have been completed with long-term performance in mind, and 25-year insurance-backed guarantees for peace of mind. The part that is commonly overlooked is the ongoing maintenance those systems need.
Regular inspections protect the look of the walls and the integrity of the system. Fail to maintain it correctly and the warranty may no longer apply. We offer inspection, cleaning, repair and planned maintenance, using compatible materials and the manufacturer’s requirements.
External wall insulation is built to last decades, but like any external finish it needs looking after. This is the timetable we recommend.
A full visual inspection of the render system. Small faults are cheaper than failed elevations.

INCA Maintenance Guidance Manual for EWI SystemsDo not wait for the 10-year mark if something has already failed. Repair cracks, impact damage, leaking gutters and failed sealants as you find them.

Annual inspection visits, maintenance reports with photographs, crack and damage repairs, render cleaning and algae treatment, sealant replacement, approved repairs, and planned maintenance packages. Protecting the system now is cheaper than remedial works later.
