We would highly recommend Williams Lift Company for their customer service, product knowledge and expert installation. We purchased a Harmar Vantage Stair Lift SL 400 and are very satisfied with the stair lift. A true commitment to quality, competitive pricing and outstanding customer service. Their employees in the field and in the office put the customer first and ensure you are fully satisfied and comfortable with the stair lift operation. A family owned team that is second to none!
