Really good and reliable company
I bought the exterior door and I love it. Phil from the sales department offered me several solutions to make me happy with colours, materials and prices. He followed me through the entire process and always answered all my questions and concerns. With him, I obtained a colour that was not that easy to get from other companies.
The installation team was also really nice. In particular, there was a guy from Bulgaria who did an amazing job in a couple of hours and left everything nice and clean.
I would definitely recommend this company 🙂
