It's not just sealed units that can fail on your old windows. There are a number of moving parts and rubber seals that can wear down to a point where the performance of the window is compromised.
Drafty windows may be caused by bent or broken hinges, or worn or missing gaskets or seals.
Jammed windows may have broken locking mechanisms or handles.
Repairs should always be considered over replacement, and as an ethical and responsible business, building on our reputation since 1986, we will always give honest and trustworthy advise, and always free of charge and without obligation. Our proud reputation depends on it!
