G.A.S GENERAL BUILDING SERVICES Ltd
Rating: 5 out of 5
Garage Conversion Specialist in Barnet, Greater London
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.

Conversions - General- 7 Nov 2016
External Works and Repairs on Large House for Freeholder We had hired Chiro to complete External Works and Repairs on the Exterior of a building that comprised 2 flats on behalf of the Freeholder. From the outset Octavian and his crew were very professional to deal with in terms of negotiating the price, start date and the works to be completed. The project involved repairing brickwork, roof tiles, ridge tiles, parapet walls, pointing, facia, plaster work, fixing windows/sills and finally sanding and painting etc and required a comprehensive repair of the exterior of the building. Much of the work was quite intricate and required careful repair of damaged areas and often coming up with creative solutions to get a good finish. The workmanship and attention to detail was very impressive and even involved them doing online research to find an alternative to old ridge tiles that were no longer available. Any issues or additional requests that arose were favourably received and dealt with immediately. The project started and was completed on the agreed dates and the site was left clean and looking well. Overall I would highly recommend Octavian and his crew to other clients.

Ged is the perfect builder for someone who does not know what to do, who to trust, or what you might need to do to achieve your ambition. We have used many different trades people, ranging from cowboys to good workers that rip you off. Ged was better than anyone we have used before. He is open, really kind, easy to talk to and most importantly professional. And definitely not a rip off. He priced the job really well, it really was amazing for what I got. He help with loads of advise, worked hard and to a good time table. I cannot express how happy we were to have Ged on our job. He and his team had amazing attention to detail. Polite and helpful. I look forward to having Ged Work on future projects soon. You are in good hands. High praise, but Ged deserves it. If you want someone you can trust, do an excellent job and be easy to communicate with, Ged’s your man.
