Newcastle is a small, largely residential city perched on the hills between Renton and Bellevue, accessible via Coal Creek Parkway and Newcastle Way from I-405. It's a city many people drive through without knowing they're in it — but residents know it well for its quiet neighborhoods, the Newcastle Golf Club, and the Coal Creek trail system. We cover Newcastle as part of our Renton and Bellevue service areas.
Because Newcastle is primarily a residential community with little commercial activity, most of our calls are home lockouts, rekeying, and car key programming for residents. The hilltop setting means some roads are narrow and winding — we navigate them regularly and won't get confused trying to find a specific address. If you're in the May Valley area or near Cougar Mountain, just give us the nearest cross street and we'll route accurately.
The Lakemont community in south Newcastle is one of our more frequent call areas — it's a planned subdivision that sees regular homeowner requests for rekeying and deadbolt installation. The Factoria border with Bellevue means some Newcastle calls are handled through the same dispatch as Bellevue's southeast areas, which can sometimes mean faster response. Call us and we'll tell you our current ETA.
