 Trustindex verifies that the original source of the review is Google. Just want to say thanks to one of your lorry drivers. I didn't manage to get his name. I got stuck in a hedge this morning (just outside of Banbridge) and your driver along with a few other lads, got me hooked up and towed me out of  the hedge. I am extremely grateful to him. I just want to say thanks again, if you could pass this on to your drivers. Thanks.

 Trustindex verifies that the original source of the review is Google. We recently had a garden room built by CG Garden Rooms and I honestly couldn't recommend them highly enough. From the first conversation right through to completion, the communication was excellent. Every question was answered quickly, timelines were clear, and the whole team was an absolute pleasure to deal with. Nothing was ever a problem. One thing that really stood out was that all materials had to be brought through our house to access the garden. I was quite concerned about this beforehand, but the team took such care and made the entire process completely seamless. They were respectful, tidy, organised and treated our home as if it were their own. The quality of workmanship is outstanding. The attention to detail, finish and overall build quality exceeded our expectations. It's clear that pride is taken in every aspect of the work. What can sometimes be a stressful project was made easy from start to finish thanks to a professional, hardworking and genuinely friendly team. We're absolutely delighted with the finished garden room and have already had so many compliments on it. If you're considering a garden room, I would have no hesitation in recommending CG Garden Rooms. Thanks again to all the team for such a fantastic job. Tara McHugh

 Trustindex verifies that the original source of the review is Google. Absolutely fantastic experience from start to finish! We recently had a garden room, shed, and hot tub room built by CG Joinery and couldn’t be happier with the results. The whole process was incredibly smooth — the team completed everything quickly without any fuss or delays, which was a huge relief. What really stood out was the service. Conaill, Michael and Sarah we dealt with was friendly, professional, and genuinely helpful at every stage. They kept us informed, answered all our questions patiently, and clearly took pride in their work. You could tell they cared about getting every detail right. The finished garden room looks brilliant and has already become one of our favourite spaces. The shed is solid, practical, and exactly what we needed for storage, while the hot tub room is a real standout — beautifully finished and the perfect place to relax. Highly recommended if you’re looking for quality workmanship delivered with real care and efficiency. We wouldn’t hesitate to use them again!
