G.A.S GENERAL BUILDING SERVICES Ltd
Rating: 5 out of 5
Garage Conversion Specialist in Sewardstonebury
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.

Lovely father son business, professional, friendly guys. I asked them to build a plasterboard wall in order to create an extra bedroom in my house, the wall was finished well, within two days and they charged me a very reasonable rate, as a young women in business I find that tradesmen often try to overcharge me but these gentleman did not. They also took a look at leak that had occured which another professional plumber failed to solve and tried to charge me over £200 just to take a look! I have and will book them on a number of other jobs.

Victor (Vica) laid some engineered oak wood flooring for us in a house that we bought at the end of 2013. The house needed lots of work doing and the new flooring was just one of the many jobs undertaken by Victor and carried out to a very high standard for us. He always paid attention to detail, ensured that the flooring was level and that the new skirting board fitted flush to the floorboards. He was also always able to provide a solution to any problems encountered during the renovation works. I would have no hesitation in recommending Victor as he takes the same pride in his work for others as if he was carrying out work in his own home.

Zak and his cousin began working on our project on the 10th of March and delivered everything on time. From start to finish, they were consistent, meticulous, and completely committed to bringing my vision to life. They worked collaboratively with me throughout the process, always open to ideas and focused on achieving the best outcome. Together, they handled everything — brickwork, building, tiling, rendering, plumbing, and electrical — with a high level of skill and professionalism. The quality of their work speaks for itself, and I’ve already recommended them to others. We are truly grateful for all the hard work they put in and couldn’t be more pleased with the final result.
