Eindelijk een professioneel bedrijf gevonden die aan de verwachtingen voldoet. De prijzen zijn goed en de kwaliteit van het product ook. Goed dat de kozijnen … read more in Pedreguer zelf gemaakt worden. Van inmeten tot het verkoopproces tot aan de montage, dit bedrijf heeft het goed voor elkaar. Of je nu een particulier bent of een bedrijf, hier kan je met een gerust hart mee samenwerken. Je kan er goede afspraken mee maken en je kunt er echt op vertrouwen.
Bij ons zijn er 4 kozijnen met een boog geplaatst, wat veel bedrijven niet doen. Daarbij zijn er veel Spaanse bedrijven die zodra je geen Spaans spreekt je 60% meer laten betalen.
Absolute aanrader! -
I was very impressed by both the quality of the products from Crystal Windows and by the professionalism of the team that installed the bifold doors we … read more bought from them. They were just what we wanted, the price they charged was reasonable, and everything went well. Installation was also quick. I have absolutely no complaints on any of that.
Where they lose one star, and I give them only four and not the full five, was for the slowness with which they responded when one of the handles on the doors was broken. It took many weeks and a lot of insisting from us that we needed some help.
That being said, the help they eventually provided was once more highly professional, the work was done quickly and efficiently, and we were left with doors that worked as new. It was great service and, again, I have no complaints.
Overall, then, Crystal Windows supplies fine products at sensible costs and installs them with high professionalism. They also provide first class support later. The one small improvement they need to make is to respond promptly when a customer needs that support. -
If you want a professional job with seamless installation and high customer service then I will recommend Crystal Windows
