About us

For over 40 years, family owned and operated

Big B Lumber has been your Full Service Building Supply Center providing a full assortment of lumber and building materials to families and professional contractors in the Bay Area. Our orientation and continuation as a family business has resulted in a high retention of employees dedicated to accomplishing our goal of offering our customers a complete mix of high quality products, at fair and competitive pricing. Our experienced sales staff takes pride in making your ideas become a reality, at home or on the jobsite.

The Big B Lumber Staff has spent a lot of time laying out our Store and our Yard, so that your shopping experience will be comfortable and efficient, and the items you need, easy to find. Our low pressure sales staff has the experience to answer most of your question, and will help you source the answers we do not know. If we do not have the product you need on our shelves or in the racks outside, we will be happy to source and order it for you.

Our service and machining capability in the lumberyard is exceptional. Our highly trained yard staff will crosscut, rip, dado, corbel or resaw lumber to meet your specific project needs. And our friendly staff will complete the transaction by loading the material in your vehicle, or delivering it to your job destination.

If you are in the market for a fence, a deck, or are building an arbor in the backyard, we have all the material you need to complete your project.

If you are located on the water and need the material to build a new dock, Big B Lumber has expanded our marine department with the most current and up to date dock supplies and flotation materials.

If you're considering a remodel or addition to the house, or simply starting from the ground up, building your dream home we have both the material and expertise to complete your project.

We recognize and respect the larger warehouse competitors in the area. But we also know what we provide to all our customers. Please stop in, we are anxious to show you our value.

Pre Plan

Many businesses fail to create a strong purchasing plan. As a result, they often end up paying too much for goods, and purchasing the wrong quantity.

Planning your purchases with Big B Lumber can help you manage your project. It takes coordination between you, our sales staff, our vendors, and our accounting department to make sound decisions for your projects.
Let a Big B Sales Rep help you make the smart choices.

Custom Milling

In our increasingly pre-packaged world of standardized products, this service is getting more difficult to find. So go ahead, exercise your creativity in your project and let us bring it to reality.

When you place an order with us, our expert sawmen are ready to customize your lumber. The custom milling process is a straightforward concept that is as old as the lumber business itself.


"Big B Lumber/Ace Hardware has always had exactly what we needed and very professional, knowledgeable staff."

- Marguerite N. Brentwood, CA

"I have been here for lumber on several occasions. Each and every time they have been friendly and helpful. You can't get better than someone asking if you need help, then helping you get your list of lumber and supplies. They even help me load it into my truck."

- Rob J. Brentwood, CA

"This place is fantastic. Lower prices than Home Depot and Lowes and somehow lower prices than the actual Ace down the Street. Friendly staff and all the odd ball parts one might need for quick fixes or larger repairs. I'll post more as we find more cool things about this place during our home owner escapades."
