Dear Lorenzo here you can provide the testimonial for the project that we have carried out for you: - Lorenzo

I employed Agstar Ltd to install a new Howdens kitchen. Because of the age of the old kitchen (nearly 30 years), the work had to include a complete rewiring of the kitchen, as well as refurbishment of an old sash window (new putty for the glass panes, repainting etc), and a new floor. Before the work even started, Avto made a number of helpful suggestions and gave advice regarding the choice of flooring, lighting etc that resulted in a better kitchen that would have been the case without his input. Avto and his team proved reliable, arriving on time and working full days, always did what they said they would, and worked as neatly as they could given the somewhat cramped space and difficult access (second floor flat up steep stairs). They responded flexibly and creatively to several unforeseen challenges such as non-perpendicular walls and mistakes in the designer's measurements, which required customization of a couple of the cupboards. Despite the job running over-schedule as a result of these challenges, the Agstar team never sought to cut corners or rush the job, as far as I could tell. In short, these guys know their stuff and I would hire them for other jobs as well as recommend them to friends. - Stovin

We posted a job in order to have a kitchen refurbishment and we ended up refurbishing the entire flat (excluded the bathroom). Avto came to our flat to check what was the job to be carried out, in order to provide us with a quote. From the beginning, he proved to be very knowledgeable and gave us many good tips. Avto sent us a very detailed quote in a very short time, we were impressed by his attention to details and decided to hire him for our flat refurbishment. Avto and his team carried out many works in our flat (New Boiler, New Electrical fuse box, wooden floor, repaint walls-ceiling- windows. New kitchen, spotlights, wardrobe, kitchen storage. Avto was always available to listen to our requests and able to find the right solutions. He can count on a team of very skilled and hard-working people. They were always polite and smiley which is definitely a great plus. Avto’s team also includes very skilled carpenters, they built an amazing wardrobe in our bedroom and storage in the kitchen, we are absolutely pleased by the result. Avto has also a great network of professionals, (Gas Engineer, Certified Electrician), thanks to which he was able to carry on our project under every aspect. The renovation was completed on time, and we are very happy with the result. Our flat is unrecognizable and beautiful and this thanks to Avto and his team and their extreme professionalism. We will definitely hire Avto again for future jobs, and we can recommend him without any hesitation. - Enrica

Avto renovated a bathroom for us in a rented flat. He has been very professional and I would certainly use him and his team again. He did a lovely job and was very calm when things went a bit wrong (if deliveries did not arrive on time for example). He never complained when I added a few extra jobs to the project. Always courteous and helpful. - Belinda
