The people who show up at your door are the people who do the diagnosis and the repair - there's no separate sales visit and separate repair visit. If a spring needs replacing, the person quoting it is the person swapping it out.
We're based on E Lake Sammamish Pky SE, which puts us close to the core of Issaquah and within a short drive of the surrounding areas we cover - North Issaquah, Squak Mountain, Issaquah Highlands, and out toward Newcastle, Fairwood, and Maple Valley. That matters for response, but it also means whoever's working on your door has likely seen the same era of hardware on a house two streets over.
We won't invent a track record here. What we can tell you is what we work on and how we approach a call: look at the door, name the actual problem, quote the actual fix, and do the job ourselves rather than handing it to someone else partway through.
