Looking for Handymen

Hi Dan, I’m looking to get my windows and doors serviced, to make sure that the house is as insulated as possible. I have noticed problems with condensation on the interior sealant of some windows, which I think is due to a lack of sealant on the outside. There is one window that doesn’t shut properly, but the rest have no such obvious problems. However I think they would all benefit from a look over, as some are quite stiff, and others seem to have shifted since the house was constructed. The windows are all either internally opening “hopper” windows, or long (floor to ceiling) windows with no opening, and we have two sets of French doors as well as the front door. Is this something you could help with? Best wishes, Jo (Scholars Walk, CB4)
