Chris and his colleage arrived at 8 am as promised and got stuck straight in. They started by covering every inch of carpet that they might possible soil with a clear plastic covering and then started installing the two new windows. The worked quickly and efficiently and had the two windows installed by 3 pm. As a parting gesture Chris stuck down a wooden bar that was at our front door that had come loose - nothing to do with the installation. We were very satisfied with the result and I can honestly say that Timber Windows are a very professional organization.
