Living in the Sunshine State we have long hot summers and we do not open our windows or patio doors very often. This allows your balance rods to seize up or even rust. Are your windows hard to open or will not stay up? Hard water and salt air can also cause your patio door rollers to corrode and stop them from operating properly causing your door to feel very heavy. The longer your windows and doors fail to operate correctly the more damage can occur! All replacements parts will be made with correct manufacturer parts. Before you make the decision to replace your windows or doors know there is another option.
