This past week we had one of our springs break just before 5pm on Wednesday, I contacted the business and Nathan answered after hours and said he would be out first thing the next morning or I could pay a premium for afterhours, so I chose the next morning. As promised Nathan and Kevin showed up on time first thing in the morning and got right to work. They knocked the project of replacing the springs and ended up doing much more in no time at all. The garage door is quieter than when we bought the place over 25 years ago. Nathan could have told me I needed to replace my door, but instead he made some modifications to allow me a few more years on this door. Not only was the service fast and friendly, but they also left no signs of them being there cleaning up the workspace before they left. I highly recommend Black Oak for any garage door work or construction!
