Our experience has shown that the elderly have more difficulty opening the sliding door to their patio or balcony than any other door they would encounter shopping downtown.
That's because all the downtown businesses conform to the A.D.A. requirements that specify no more than five pounds of pressure is required to open or close any door.
We make sliding patio doors compliant with A.D.A. (actually exceeding their requirements) in your own home. We carry a special tool that measures the force required.
