Excellent experience. I commissioned them to conduct aluminosis tests for an apartment I'm in the process of buying, and they were quick both in the site visit for the samples and in delivering the report (it takes a week with analysis from the independent laboratory at the UPC in Barcelona). They were consistently professional, technically rigorous, and provided excellent customer service. It gave me great peace of mind in such an important decision as buying a home. Thanks to Raúl Heras Diez for his kindness. I would definitely recommend them to anyone needing this type of technical analysis.
From the very beginning, Raúl has helped us a lot and has solved all the doubts we had with great professionalism and kindness. The whole process has been very fast: we had the appointment and the results in less than a week. The treatment has been a 10. Without a doubt, I will recommend them to any friend or acquaintance who needs to do an aluminosis tasting.
Very fast, professional and friendly. We were unsure about the quality of a potential flat and after doing some tests with Sinluz, all our doubts have been answered. And we even got some free advice on top! Thank you!
Raul has been amazing. He come to my place found the right spot and took a sample of the cement. In 3 days and half we had the results. Precise, cleans and easy going. I can not be happier!
Outstanding service, tenacious attitude and an empathetic approach to his customers.
