We have used them and are now very, very sorry that we did. Must be one of the most despiseable contractors around. I'll be happy to expand on that if necessary. Just my humble opinion: don't give them your money, they don't deliver what you expect. We are left without sliding door, without architraves at the bbedroom door, without our plan for the wiring and with lost of malfunctioning electric switches...really great... Really, I guess you won't be friends anymore if you use them. As a hint just try and contact them on their so called Hotline given on their webpage. They will not answer in person. That is so because also the promised office in roxy square does not even exist (shop is up for rent). Their personal HPs are constantly not available (they have long changed numbers).
