Loft Conversion- 5 Dec 2018
Firstly the date of job posting and date of completing is all down to me not being ready with finances!! Secondly, and more importantly, GG Property were the most wonderful and professional bunch of lads you can hope to met. The work was done with such enthusiasm and to such a high level of detail. We could not be happier with the finished job. Thirdly, the great building work aside, GG Property were polite, happy, friendly, punctual and great communicators. All emails answered swiftly and with accurate information. No question was to silly and no concern (this was our first major building working) was to small to be addressed. Finally we are so pleased with work we are awaiting a quote for our bathroom and look forward to getting that job completed!! In short my experience with GG Property was nothing but top quality work and customer service. Any fears of the classic 'cowboy builder' could not be further from the truth; GG Property are a hard working truly lovely bunch and we would highly recommend them.

Extensions- 14 Jul 2021
Juro and his team completed a total refurbishment of our house that included removing all internal walls, along with a double story side extension, a huge job involving lots of steels, re-roofing, new construction, new bathrooms and kitchen, new windows and rendering along with all the plumbing and electrical work and decoration. They did the most incredible job, working efficiently, adapting to any problems that came along and working really hard to create the best finish possible at the budget we had. Despite the pandemic arriving just after the demolition stage, they didn’t miss a day on site, and worked tirelessly to get materials to keep the project moving. Incredibly they still managed to finish the project on schedule and to a standard that was exceptional. Juro is honest and upfront, didn’t ever add costs or ‘unforeseeables’ and was an absolute joy to work with. He also stuck to a very clear payment schedule that was easy to follow and always meant we only paid when we were absolutely 100% happy. My only reservation in writing this review is that I would like to selfishly hang on to him and keep his schedule clear for future jobs with family and friends!

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

Extensions- 8 Dec 2017
We couldn’t be happier with the professionalism and quality of workmanship from REA Construction. The project was delivered within budget and on time. We lived in the property during the work and we, our neighbours and the site were always treated with the utmost consideration. There were almost no hitches and, when they did occur, they were dealt with immediately and thoroughly. Our project team, led by Kristjan and Besi, were universally hardworking, organised and produced work to an excellent standard. Communication is great, the people are wonderful. Renato was someone I felt I could trust from the moment I met him and he never let us down. He and everyone at REA genuinely care about what they do and that their customers have a happy experience. We certainly did and would have no hesitation recommending them to others.
