Family-run Windows PC repair, upgrades, and custom builds in downtown Delta — owner Roger Robinson brings over 30 years of hands-on experience, going back to the shop's roots as Eastwind Computers in the Pacific Northwest.
For more than three decades, Cornerstone Computers has served the Delta community with expert PC support and repairs. We specialize in Windows computers, offering everything from virus removal to new system setups and upgrades — with approachable service and technical skill that makes the experience seamless and stress-free.
We started as Eastwind Computers in the Pacific Northwest over twenty years ago. As our family grew, so did our dedication to providing reliable, straightforward help for technology needs. We don't work on Apple computers — our focus is on Windows systems for home, gaming, and office. We listen, explain in simple terms, and make transitions easy.
"We combine technical skill with a sincere approach to customer care — no matter the issue, we offer clear communication and practical solutions."
