A specialist in building envelope systems, ventilated façades, insulation, airtightness, cladding and building performance improvements. George Sora founded RetrofitIQ (operated by G.A.S General Building Services Ltd) to bring building science and forensic diagnostics into the world of residential construction — a sector dominated by guesswork, generic remedies and over-promised “fixes” that don’t address root cause. With over 15 years of hands-on construction experience and more than a decade of specialist work in building envelope systems, ventilated façades, internal & external wall insulation, airtightness detailing, cladding installation and retrofit-grade insulation, George combines deep practical knowledge with formal Passive House Institute training as a Certified Passive House Designer.

That dual background — designer-trained and installer-experienced — is rare. It means George can specify a solution that works on paper and deliver it on site, with the joint detailing, vapour control and airtightness layers actually built the way the spec demands. Every project starts with a diagnostic — visual inspection, FLIR thermal imaging, blower door airtightness testing, moisture mapping and analysis — before any remedial work is recommended.

Where appropriate, post-works verification is used to confirm the improvement is real, not assumed. After years of seeing projects fail because of the disconnect between designers, contractors and inspectors — symptoms misdiagnosed, specifications missing the root cause, installations deviating from the spec, verification skipped entirely — RetrofitIQ was created to bring investigation, design, installation and verification together into one coordinated process . One point of responsibility, from the first FLIR image to the post-works re-test.

RetrofitIQ was created specifically to bring all of these stages together into one coordinated process. Rather than using separate assessors, designers, contractors and inspectors, clients work with a single company from the first FLIR image to the final post-works verification re-test. RetrofitIQ combines investigation, diagnosis, design, remediation and verification into a single process — one company, one process, one point of responsibility.
