Hi. We installed 4 casement windows in our house LA 20 years and the crank hardware is going to pieces and needs to be replaced. Your video for replacing them is as clear as can be but beyond my abilities as an unskilled homeowner. I'll need to find somebody to do the work, but hopefully you can help with the right replacement hardware. On two of the windows the channel that attaches to the swinging window itself was never installed. Lastly, do you have any referrals for somebody in Los Angeles who can do this kind of work?
Many thanks,
Stephen
