We do upgrades on screen doors that have seen better days. Working on a older home today in Thousand Oaks a client wanted to not spend a lot of money and asked me to please just repair her patio door, so we checked it first to see if it was possible and got started.
For an upgrade we first take out the old mesh, then we make sure the frame is straight to put on new screen. After the frame id in good condition we install new rollers and adjust them for a proper fit. All doors are different but we have been doing it for over 15 years and we specialize.
