We used AGS to install our doors a few years ago- they’re fantastic quality. The team provided a great service. We recently had a problem with our key and when I called up to ask for advice, they came to our aid straightaway! Couldn’t recommend enough!
Really helpful knowledgeable Customer Service. Good communication and professional Engineer with good interpersonal skills. Well worth investing in the skills of this company and its people.
Another great experience with AGS. Having used them before, I’m pleased to say the service and delivery remain consistently excellent. The new front door installation was handled professionally from start to finish, and we’re really happy with the result.
