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.

Hard Flooring- 28 Dec 2021
Emanuel and his team have delivered the project despite Covid-19 challenges and our changing requirements. We have changed our mind about design and finishes a few times during the project, and LIO were there to listen, advise and deliver. The communication was excellent throughout the project, and the works were finished on time. We will use them again.

Extensions- 17 Aug 2026
I had a very poor experience with this contractor and would strongly advise potential customers to be cautious before paying substantial sums in advance. I paid £3,672 by bank transfer following an invoice for the supply of structural steelwork. There were significant delays and communication issues, and the steel was not supplied to me as agreed. After giving him opportunities and clear deadlines to resolve the situation, I terminated the agreement and had to make alternative arrangements to keep my project moving. Most concerningly, despite my requests, the £3,672 I paid has still not been refunded as of the date of this review, and I am now pursuing the matter formally. Based on my experience, I cannot recommend this contractor. I would advise anyone considering using his services to be extremely cautious about making advance payments. I will update this review if my £3,672 is returned.

Bathroom Fitting- 1 Sep 2026
Sadly…Still have the bath tap leaking. Flooded the bathroom and kitchen Broke the thermostat for the central heating. Condemned my cent heating and now need a new heater £4,000+ The freeze kit didn’t work and should have used the proper machine instead of a temporary Quickfit kit smh and then many times coming to do the job properly (even got a gas engineer that wanted to charge £150 for a job not done grrr)… £801 charged for a new sink to be installed… yes it’s a old flat (like said in the description). Very disappointed for an expensive job that’s not properly done, even now… can’t be bothered to call him back in case it’s more money. We come to these sites expecting true professional…

Extensions- 24 Jan 2021
We chose Gibbons and Sons for our Loft extension and new bathroom as they was one of the few firms who we contacted and was more then happy for us to view their workmanship during and after the build so we good see the quality of their works. They have been courteous, polite, very patient and accommodating to our chopping and changing of ideas. They helped us to bring our visions to life and offered advice when required without being pushy and driving a hard sale. They have been open and honest with our ideas and their recommendations and in some cases suggested a alternative more cost effective option. All in all we would highly recommend Gibbons and Sons for all types of building works.

Loft Conversion- 6 Sep 2024
I recently worked with Ardit from AK Constructions and Developments on a double dormer loft conversion, which included creating two large bedrooms, a bathroom, and a utility room. I'm delighted with the results; the quality exceeded my expectations, and everyone who's visited has been impressed. Ardit's approach was professional and not pushy, unlike other builders. He provided references and even invited me to see a current project, which convinced me. Ardit was flexible, suggesting changes like moving the bathroom for better functionality, which turned out great. His team, including Edi and Vini, were polite, courteous, and always willing to help. The work finished ahead of schedule, and Ardit sourced excellent tradespeople, making the experience stress-free. I was so impressed that I also asked him to redo my kitchen, and I'm thrilled with the outcome. I highly recommend AK Constructions and Development.
