Two window blinds would now fit our new (upgraded) windows. Provided the inside frame measurements (be sure to check the dimensions in more than one location). Took the blinds to this company and had them back in 2 days with a perfect fit for both blinds. This company also repaired two blinds where the strings would nolonger lift the blinds. Theyou showed me the worn parts and explained the cause. They also removed some of the weight in the bottom bar to make the blind lighter thereby reducing future wear - removing the excess weight did not impart the operation of the blind and both mechanisms are silky smooth. Both blinds were returned in 2 days. Highly recommend this company as a goto for window blind repair.
