The Door Guy

I've had customers defer to my experience after a spring tore them up, and then broke their arm. Winding the spring appears to be where the trouble lies. What I see most often with sliding glass doors is that when wheels wear out, it gradually gets harder and harder to open the door. I have had customers give me a doctor's prescription to get their door fixed in order to prevent carpal tunnel surgery. Your storefront door welcomes your customer into your business and says "Please stay and buy something".
