Sticking sash windows

We called in Jim to help us with our sticking sash windows.  We've not owned a home with sash windows before and Jim not only sorted out our sticking windows but told us how to use the sash windows to ensure that we obtain the most effective ventilation for our home.  He was very courteous and helpful, left us with some spray products for the windows and told us where to obtain further supplies when we need them.We are happy to recommend.S & B - Trinity Trees Eastbourne 16/08/2012
