ONE COMPANY. ONE PROCESS. ONE POINT OF RESPONSIBILITY. Hi, I'm George Sora, Certified Passive House Designer and founder of RetrofitIQ powered by G.A.S General Building Services Ltd. My approach is different from traditional builders because every recommendation and every upgrade is based on proven Passive House Principles and building physics, not guesswork. Whether the problem is condensation, mould, damp, heat loss, air leakage, poor ventilation, uncomfortable rooms or excessive noise, I follow a structured process designed to identify and solve the root cause: INVESTIGATE → DIAGNOSE → DESIGN → REMEDIATE → VERIFY Using professional equipment including thermal imaging cameras, moisture meters, blower door airtightness testing, smoke tracing and ventilation assessments, I can identify hidden defects that are often missed during standard inspections. As a Certified Passive House Designer, I apply the five key Passive House Principles wherever appropriate: • Airtightness • High Performance Insulation • Thermal Bridge Reduction • High Performance Windows & Doors • Controlled Ventilation This allows me to deliver solutions that are not only visually finished to a high standard, but also healthier, more comfortable, more energy efficient and built to perform long term. Services include: • Thermal Imaging Surveys • Blower Door Airtightness Testing • Damp, Moisture & Condensation Investigations • Ventilation & Indoor Air Quality Assessments • Soundproofing & Acoustic Improvements • Internal Wall Insulation • Loft, Floor & Roof Insulation Upgrades • Air Leakage Reduction • Retrofit & Energy Efficiency Improvements • Refurbishment & Building Works From diagnosis through to completion, clients deal with one company and one accountable team. No guesswork. No unnecessary treatments. Measured. Diagnosed. Designed. Remediated. Verified.
