"I could not figure out why my old double hung windows would not open. I called Max and he immediately identified and resolved the problem. My windows are in an old plantation home in Hilo. They were constructed 100 years ago with a rope and pulley system. Over time the ropes had worn out and the weights had fallen into the bottom of the pockets. Max removed the covers from the pockets, replaced all of the weights with new rope, treated my windows for termites and made them all operational again. I would highly recommend LOMAX for window repair."
