Working in Hillsboro

What's it like to renovate a Hillsboro home?

Hillsboro is two cities at once. Around Orenco Station and the tech corridor, thousands of homes went up in the late nineties and two-thousands, and the oldest of them are now due for their first roof replacement and their first serious siding maintenance. On the edges of town, farmhouses and rural properties have been standing through Oregon winters for a century or more.

Those are very different jobs. Newer construction often means builder-grade materials reaching their design life all at once. Older rural homes mean outbuildings, additions, and decades of layered repairs. We're comfortable in both, and honest about what each actually needs versus what can wait.

From roofing and siding to windows, gutters, and decks, every Hillsboro project starts with a free walkthrough and a written, itemized proposal.

Questions from Hillsboro homeowners.

Is Cornerstone actually local to Hillsboro?+
Yes. Our office is at 9845 NE Eckert Dr, Ste. 210 in Hillsboro, and we are licensed, bonded, and insured under Oregon CCB #261422. When we say we know Hillsboro's mix of tech-corridor subdivisions and century-old farmhouses, it is because they are in our backyard.
Do I need a permit for a Hillsboro roof replacement?+
Hillsboro runs building permits through the city's online Permit Portal, and when a permit is required the minimum fee is $64.90 plus a 12 percent state surcharge. Like-for-like reroofs often need no permit under Oregon's 30 percent rule; anything structural, like rafter repair or re-sheathing, does. We confirm which side your project lands on before work starts.
My Hillsboro home was built in the late nineties or two-thousands. What should I watch for?+
Builder-grade roofing and siding from that era are reaching their design life all at once, especially around Orenco Station and the tech corridor, and the oldest of those homes are now due for their first roof replacement. We will tell you honestly what needs doing now and what can wait.
