Firbank

"First and foremost we are looking for quality in our windows and doors… we’re delighted with the end results. It always works well in the end and we are very pleased."

- Roger Carter, MD of Carter Construction

A luxury development in Derbyshire featuring Rationel

I’ve been working in the construction industry since I left university, and I’ve been running Carter Construction since 1988.Our goal is to provide the best quality we can achieve with the best products we can use. There you go, there’s a good strap line!

Firbank is a development of five exclusive quality homes in Duffield. We chose the Rationel product for our windows because we are very happy with the way the system works, the fact that the windows are a factory finished timber with an aluminium clad outer face, it means the quality is excellent and it conforms with the level of the product that we are trying to sell.

First and foremost, we are looking for quality in our windows and doors. I chose Rationel for my own house, in 2010, which we are extremely happy with; they still look as good as new now.

How was working with Ecotec? Well, all good! I would say that because of your process we do have a bit of back and forth to get all the details right – but by the time we do get to the final order, everything is agreed. And of course, when it turns up on the lorry, it’s what we ordered, so no complaints there. We are ordering expensive kit here, and if it’s not right or it comes out wrong, who’s to blame? Ultimately, your system washes out those problems. We’re delighted with the end results. It always works well in the end and we are very pleased with it.
