At 4 miles from our Tukwila shop, Normandy Park is close enough that we can carry hardware sized for older doors without guessing. That means torsion springs wound for heavier, older steel panels, track sections in the gauge these houses actually used, and header brackets that match lag-bolt spacing from the era rather than newer stud patterns.
We stock what covers cold, moderate winters - the kind of weatherstripping and seal kits that hold up through freeze-thaw cycles rather than cracking after one season. What we don't carry is a guess. If a door's original hardware turns out to need a part we don't have loaded, we say so rather than forcing a mismatched fix that won't hold. On a house this age, that's the difference between a repair that lasts and one that's back on our schedule by spring.
