Replaced windows and doors. Nice people from Signum who provided good information along the way. The craftsmen were skilled. Very happy with the result.
Signum replaced 9 windows, 1 balcony door and 1 sliding door at our place. Very satisfied with the work that was done. Good process from start to finish - from inspection, execution of work and review of the final product.
We hired Signum to change all the windows on our house, and we couldn’t be happier with their service and craftsmanship. From beginning to end, it was a joy to interact with them. Communication was very good, the price was as expected and promised, the work was done in a timely manner and with great quality. We had them back a few years later to install a new front door, and even though they sent a different representative to do the planning and had different workers doing the actual the work, it felt very much like the same company with the same set of standards and quality in their work. We’re recommending them to all of our friends.
Too expensive, not happy with the result
I chose Signum when I needed to change 8 windows and a door at my house. It was a great experience. Andreas is a dedicated professional who provided excellent advice. Everything was delivered as expected and with very good service and transparent information. I would not hesitate to choose Signum again!!!
