I placed an order with this company to repair/replace the rotor gear (which opens and closes the window) on one of my casement windows on April 24th. Work was finally done on May 11th. While the service person was competent and polite, I was charged a total of $230.15 for a job which took abt.30 minutes. The distance from their shop to my house is approx. 5 minutes by car. When I placed the order, I was advised that the cost would be approx. $ 150.00 The service person insisted that the $150 was the standard charge for a service call. Complaints for the over-charge - both verbal and in writing - were fruitless.
