Interior of Lakeside Lumber showing well-stocked shelving with quality lumber and building materials

A cornerstone of Eureka since day one

Lakeside Lumber Inc. has been a fixture on G Avenue for decades — not just a place to buy two-by-fours, but a place where builders, homeowners, and tradespeople come for honest advice and quality materials.

When you walk through our doors, you'll find a team that knows the difference between construction-grade and select-grade, that can tell you which wood is best for a deck in our climate, and that will never sell you more than you need.

We're not a big-box store. We're your neighbors. And we take pride in helping you build right the first time.

We've been buying our framing lumber from Lakeside for over ten years. Their cuts are accurate, their prices are fair, and the folks here actually know what they're talking about.

I'm a weekend DIYer and I always feel a little out of my depth at big stores. At Lakeside, someone actually takes the time to help me figure out what I need — and what I don't.

When I needed a special order of trim for a restoration project, they got it in a few days. That kind of service is hard to find these days. Highly recommend.
