Every time I walk in here, I'm always greeted. Staff is very friendly. I asked for something and lady who worked there almost held my hand bringing me to where the item was. I also get my lumber here for my projects and I notice the lumber prices are cheaper for some and more expensive for others compared to the big box stores near them. Don't care though, their staff is why I come to them even if it's a small margin off. The boys in the back always messing around, having fun when I'm there but as professional as can be when I'm ready. Coming here for all my future projects

Big B has been my go-to lumber yard since 1990. Quality is great and prices continue to impress me. With my frequent $500+ purchases, delivery (often same day) is free. Great staff...Royd and John are super knowledgeable at the counter. Love my Big B Lumber.

This is a nice store . ..however, a certain employee is wearing his mask not covering his nose. Trio is his name. It will keep me out of there.

I spent $75 here trying to support my local Ace Hardware store instead of going to Home Depot like I usually do. I'm new to the area. I forgot my $5 Ace Hardware coupon and the checkout gal told me if I brought it back same day she'd credit me.
I did and then she said they weren't really Ace and couldn't honor it. She asked the manager and he refused to honor it saying they aren't technically Ace and my coupon was for Oakley Ace.
Really dude?! I have a shopping problem and you just blew a bunch of money and a good paying customer for $5!?
Poor customer service. And she

Love Big B. I went to Concord branch originally do to job locations and followed the great staff to Brentwood. I won't buy lumber from Home Depot or Lowes. Only Big B. They have the best material and the counter people can answer any questions you might have

It definitely has more variety of wood than your local home depot or Lowe's. They seem to carry the lowest quality for outdoor trim work because 7 out of 10 times most of trim wood they have is warped or cracked.

I came here with my boyfriend because we needed to check out some wood to redo part of our fence. Everyone was cheerful from the first step inside the store. The cashier was really nice. The gentleman who was at the desk giving us quotes was also every nice and helpful as well.

Then we headed towards the back of a the store, the lumber section outside. The gentleman who was very helpful and informative was named John. He answered all our questions since it was our first time building a fence, we had very little knowledge. John was super chill, amazing and friendly. We will mos def be back once

Honestly the poorest quality customer experience I have ever received. I asked a lady at the counter to help me and she told me I should ask her co worker who was helping another customer. And then she continued to use her phone. Next the gentleman that was said to be able to help me refused to show me where product was located. He did not want to leave the desk to help me. I thought this place would be better than a home Depot or Lowe's, but regret not taking the longer drive down the street.

We just bought lumber here last week for a patio, and the whole experience went super smooth thanks to Michael. Michael gave excellent customer service, he made me feel confident that there wasn't anything lost in translation of not ordering in store. They delivered the next day, and the quality of the wood was better than I expected, very impressed. Will definitely be back soon!!

The staff inside the store were very nice. Got outside and the gentleman waiting on Phil and I was very rude immediately as Phil was looking at the wood he had purchased to have cut. It got to the point where he said that if we didn't like the wood he gave us, to go back inside and get our money back. All of the other guys their are very nice to work with.

I've been shopping here for years. Their hours have always been a mystery to me, and why they can't be open later, especially on the weekends, doesn't make any sense. The other day I was passing through Antioch when I stopped at the Sunset Drive Ace Hardware and I picked up a plumbing fitting. When I got to the job in Oakley, I discovered I had the wrong part. Assuming I could swap over to the correct part at the Oakley Ace, I went to this store with part and receipt in hand. I explained to the clerk I just needed to make an exchange. I grabbed the right part, returned to the

What a rip off! Purchased a 8" circular fluorescent light bulb. Charged me $15. Found same item at Lowes for $5.79. I suggest you carefully check their prices against other shops.

Overall it's been a very positive experience. The staff is very helpful. If you have a question be sure to ask, everyone there is willing to help. It's one of the few places that has an extensive lumber yard. I found cedar here to make a raise bed vegetable garden. They even cut the it for me.

Don't call here looking for brass fittings. Maybe there was a language barrier with the gentleman on the counter since he spoke with an accent but I was on hold for 30min. I know it's hard to find good help these days but come on.

Typical crooks. They sold me marine plywood (skid Guard) at $125.00 per sheet, total 20 sheets, for my dock. Told me it would last for at least 10 years. That's why you pay twice as much for it. After 4 years it's peeling and chipping like cheap paint.

I brought them pictures etc. They told my tough luck, they don't warranty it. That usually it last at least 5 years ( a completely different story when I was buying it). To call the company who makes Skid Guard. I called them Olympic Panel 800 782 7265. They told told me to screw off. They'll only warranty it for

My contractor didn't pay Big B, instead of going after my contractor they kept calling me trying to get me to pay them, then they file a lien on my house. I gave them $10,000
All I could afford, to stop them for filling a lien, but that wasn't good enough for them.

I am disable unable to work but do they care, he'll no all they care about is the money. Please don't shop at this place the owners don't care how they treat people, all they want is there money no matter how they get it.

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.
