I’m handy and have all the tools. Thinking of doing the Wayne dalton 16 x 8 myself. Springs are internal so it’s different from my current door and its spring system.
Any homeowners tackle this themselves & was it worth it? It’s either $1,200 for a new door or $2,100 for an installer to come and do it for me (largely because I’d need a new garage door opener with a battery, $700). I can reuse my old garage door opener if I do it myself. #diy source
