The entrance was different than the google maps location so I took photos for anyone else.

We just got a pack of pvc wood slats so hoping they turn out well and how we need / want to use them.

I found them online as a supplier of the specific style and material that I needed. When I came in, everyone was very friendly and helpful. When I mentioned what I was looking for, I was introduced to Belinda who would be the person to help me out with my custom order. Belinda kept me updated on the status of my order and when it was ready to pick up. It was so refreshing to be helped by someone professional and provides excellent customer service, which hasn't always been the case at other hardware stores. I will definitely be returning to Main Building Materials for my custom millwork and general hardware store needs. 100% would recommend.

Great store in the middle of south central. All you could need for plumbing and kitchen, at…read morediscount prices. Cheaper than other Plumbing stores around, and if they don't carry something, they're happy to order it for you for next day arrival. Their diagrams even have all the parts broken down, so you can buy just the part you need and not the entire trim kit for a sink (as other hardware stores will try to sell you). By coming here, I got just the $20 handle I needed, instead of the $183 kit, or $250 kit and valve which EVERYONE else was trying to sell me. Very much appreciated. Pro Tip: free parking in the lot connected to the store, fenced in.

This is a great place with outstanding customer service. I own an oxygen tank that I needed to get…read morerefilled. Unfortunately, the safety certification for the tank had expired. So that needed to be taken care of - with a hydro pressure test - before my tank could be refilled. When I explained the situation to Wayne, he offered to have my tank tested and filled by his supplier, on an expedited basis. Because I needed the oxygen right away for an ongoing project, I asked if he knew of any locations in the LA area that will do hydro testing on an immediate walk-in basis. That was not an option, since that service is no longer available locally. But he came up with an even better, generous solution: he kindly offered to loan me a brand-new tank filled with oxygen to get me started, and to arrange for my tank to be tested and filled, and to exchange the two tanks as soon as my tank came back from testing. As the other reviews indicate, Wayne is great to deal with, friendly and knowledgeable, and truly devoted to providing customer satisfaction. I recommend United Welding Supply highly.
