Because Clinton's housing clusters around 1987, we carry extension springs in the sizes that matched that era's standard door weights, along with the stamped steel brackets and safety cables that era often lacks or has lost over time. We also stock replacement photo-eye sensors, since many older systems never had them installed and some local code updates since have made them expected.
We carry a range of torsion conversion hardware too, for homeowners who'd rather move off the aging extension-spring layout entirely rather than keep repairing it piece by piece. That's not always the right call - sometimes a straightforward spring and roller job is the cheaper, faster fix, and we'll tell you when that's the case rather than upselling a conversion nobody needs.
What we don't carry on the truck: parts specific to high-end or imported door brands that show up occasionally in newer construction. Those sometimes require a manufacturer order, which can add a few days to the job. We'll flag that up front during the estimate, not after we've already started.
