If you're remodeling and haven't checked out Granite Expo in Pittsburg, you're missing out on a…read moretrue hidden gem. They consistently deliver high-quality materials that actually add value to your property--not just visually, but in durability and function. Their kitchen cabinets are solid wood (not particle board) with soft-close features, and the craftsmanship is immediately noticeable. The countertops, sinks, faucets, and flooring are all top-tier for the price point--you genuinely get more than what you pay for. What really sets this location apart is the customer service. I've been to other Granite Expo locations, but Pittsburg stands out by far. Ray has been incredible to work with--he helped us back in 2013 and again in 2026, and his knowledge, patience, and attention to detail make the entire process seamless. I've been recommending this place to friends and family since 2013, and it continues to deliver every single time. They are consistent with reliable quality, great pricing, and outstanding service. This has become my go-to place for remodeling and renovating properties. It's hard to find all three--quality, value, and service--in one place, but Granite Expo Pittsburg delivers every time.

I recently did some concrete work in my back yard. I called Antioch building materials to get a…read morequote on some concrete. I expected better from them. They asked me how I was going to get the concrete to the backyard. I replied a wheel barrow. Now, I manage a large plumbing company and offer my customers fantastic customer service as without them we could not keep our lights on. At this point the customer service rep should've informed me of the $2/min standby charge. I was not informed of this charge until 2 yards of concrete was unloaded. An additional $400 unacceptable! If they would've told me there was a standby charge I would have gotten a concrete pump. Thanks Antioch building materials. I feel like they completely took advantage of me. I think it is comparable to going to a restaurant and get the bill only to realize that there is a surcharge for sitting outside! I would highly recommend using another concrete company. One who doesn't take advantage of its customers! To add icing to the cake there were 10 or so cigarette butts left on my driveway, disrespectful!

This business totally ruined my garden dreams. They took advantage of a sick person who has been…read morebedridden for the last two years and just started getting out of bed and started gardening. I purchased their 420 gardening mix which THEY THEMSELVES RECOMMEND for gardening purposes. When I started watering the soil, as the water contacted the soil it became apparent that is was mostly sand. I proceeded to do a quick soil test where you put your soil in a jar and shake it. The contents will fall on to the bottom and separate into layers. To my eye, it looked like it was 60-70% sand. I kept calling asking questions about the soil, BUT Theresa, the owner kept going in circles, repeating their no refund policy and stating they haven't had issues with the soil. Understandably so I got impatient and upset with Theresa and told her that the product is a scam. I will admit, I was upset and hung up on her as she DID NOT APOLOGIZE ONCE. She kept telling me "I'm sorry you feel this way but the soil is good, I don't know what to tell you." The whole time I was on the phone with her, which was multiple times, she never told me that she was the owner. I asked to speak to a manager. She gave a number to call. Well, it turns out she referred me to her soil supplies. This guy mixes the soil himself. According to him it is 50% sand. A quick google search will tell you that soil should not contain more than 25% sand. Their supplier, whom Theresa referred me to, told me the sand content is 50%!!!!!!!!!! I spent 4K thousand dollars on this garden, paid guys to fill the beds and not I have 5 cubic yards of unusable soil. I posted about this in my local Facebook page and other people are reporting the same issue. I'm being quoted thousands to dig it up and dispose of it. This soil should not be marketed as a gardening soil. I'm sure it's great for other things but not gardening. It is a scam and it will ruin your gardening dreams. I also purchased some pea gravel, that I love. But their gardening mix is flawed and needs fixing. Please don't make the same mistake as I did. This business has no integrity and goes as far as to slander their customers and make it out to be the customers fault. I hung up on Theresa because of many reasons one for them being that I'm severely ill from very difficult medication I'm taking and running to the bathroom with nausea and vomiting multiple times per day. The owner has since attacked me personally online on Facebook where I asked if people were having issues with the soil. She hasn't apologized or attempted to try to remedy any of it.

This company/ manufacturer deserves 0/5 for its lack of customer service…read more WARNING‼‼ Do not make any purchases at this location/company I am beyond frustrated with both GE and Lowe's and feel absolutely disrespected as a customer. I purchased a GE appliance from Lowe's with the expectation of quality, reliability, and support. Instead, I received a defective product and have been caught in a nightmare cycle of poor customer service, long delays, and finger-pointing between the two companies. Lowe's, you were quick to take my money but have done nothing to stand behind the product you sold me. Your "customer support" has been nothing short of dismissive and useless. Every time I've reached out for help, I've been bounced around, left on hold, or told to "contact the manufacturer." GE, your product FAILED. And your response? A technician visit with weeks of delay and zero urgency to fix what should never have been broken in the first place. No accountability, no compassion, and no resolution. The lack of responsibility from both sides is shameful. I am now stuck with a faulty appliance, hours of wasted time, and zero resolution in sight. This is not how customers deserve to be treated -- especially when we trust you with our homes and hard-earned money. If you're considering buying from Lowe's or GE -- DON'T. If you value your time, money, and sanity -- look elsewhere. Been over a month and still no working dishwasher!
