Two days with new windows throughout the house. The projected energy efficiency rating after the window replacement dropped from 156.5 to 148.9. I pointed out that they were triple-glazed windows with argon gas in one of the panes. They asked me to send the technical specifications for the windows. Final result: 122.9. The sound insulation is impressive. The installation team was IMPECCABLE. Everything was clean and there was hardly any disruption.

I'm returning as a customer, and just like last time, the windows are excellent and very well made, both in white and wood tones. The performance is unbeatable, and the customer service is outstanding—they were incredibly attentive and checked everything I asked for. Many thanks to Sergio and Raquel, also for their patience. I've been a very persistent customer, but they always handled it with tact and elegance, making me feel very comfortable and satisfied.

We just had all the windows installed in our house and we're thrilled, both in terms of quality and comfort—it's a game-changer—and the workmanship. They were true professionals, a 10 out of 10! They worked with meticulous care and cleanliness, and their customer service was impeccable. We're absolutely delighted. We highly recommend them.

We just had all the windows installed throughout the house and we couldn't be happier! The windows are perfect, the installers' work was impeccable, they left the house spotless and the windows perfect, and they were super fast and professional! Thanks to the whole team for the quick, easy, and excellent service! I'm attaching a photo of the window; it's missing the baseboard, but it was added later :)

From the very first call, I could tell they were professional, punctual, and had excellent communication skills. I contacted them to install new windows throughout my house, and they did an impeccable job. During the initial visit, Sergio advised me with complete transparency and honesty on what would be best for the orientation and type of windows. From then on, everything was very well coordinated and organized until the day of the installation. It was a wonderful experience (and it's not easy to find people like this when it comes to renovations). They are very clean and organized while working, and the installation they did was beautifully finished. I will recommend them to everyone I know without hesitation! Seriously, don't hesitate to contact them for a quote because they offer high-quality windows and workmanship that are perfectly matched to the price.
