On the hunt for a front door as the current PVC one that was installed prior to owning the house has had horrible fitting. Never received any paperwork for the windows and doors installs, but they're not great. Realistically i do need a composite door as the PVC one really hasn't got much insulation to it at all it seems. But having read reviews on Solidor i feel like avoiding them at all costs, Endurance appear better. Hoping to use a local supplier and installer to avoid headaches. I just have such little faith these days in big company workmanship, regardless of where it's built.
