By this time i have zero faith in their system and i've got a contractor waiting for this stone, i was forced to drive to Fontana to the manufacturer yard taking time out of my day, thank god i have a truck. They mean well, but i feel like it's just another desert company barely doing enough to get by. Or maybe they have people doing $10,000 orders multiple times a day and my order is nothing.

I've been going here for years and the environment that they created here is the best. It feels like you're hanging out with friends while getting parts inbetween jobs. Also it seems like any part you'll need on a job they have a surplus of. Plus they have an awesome delivery service, so when I have multiple jobs going on I can have my lead installers create a parts list and they'll drop it off. Its the best thing imo. Highly recommend giving them a visit on your next parts run

He spent as much time as I needed in selecting a little over 95 linear feet of wood. It is for door casings and baseboards with the finished wood to be the star of the detail.

Also when I arrived too late on a Saturday and left a voice message, someone was kind enough to return my call. I was there about 3 hours.

10+ Years of Loyalty Dismissed Over Poor Customer Service and Lack of Integrity…read more I've been a consistent customer of Resource Building Materials for over 10 years, frequently purchasing materials for both residential and commercial projects. Unfortunately, my most recent experience was deeply disappointing and has made me reconsider ever doing business with them again. On June 4, 2025, I purchased epoxy/resin products totaling $1,821.00 for a paver protection project at my home. These products turned out to be incorrect for the job, a mistake made by the contractor I hired. Wanting to resolve the issue properly, I attempted to return the unused and sealed materials on July 1, 2025--only 27 days after purchase, well within a commonly accepted 30-day return window. I spoke with Alexis, and later her manager Diego, who both demonstrated a stunning lack of professionalism. Initially, I was told flat-out that no refunds are allowed, which was surprising considering my long-standing relationship with the company. I calmly asked them to review the disclosures printed on the bottom of the receipt, which clearly state that returns are subject to a 25% restocking fee--not a total denial of return. Once I presented the facts, they pivoted and claimed the return was being denied because the purchase was made "over 30 days ago"--again, not true. I challenged them using the original purchase date and receipt, proving that only 27 days had passed. At that point, their excuse changed again: Diego questioned how they could know if the product hadn't been left outside in the sun. I found this completely unacceptable and insulting. For the record, the product has been sitting untouched in my garage, easily visible, stacked in sealed 5-gallon aluminum buckets. I immediately recognized them as unused materials and attempted to return them before any legitimate window would expire. This felt like an intentional effort to avoid issuing a refund or store credit--completely dismissing my long history of business with them. Rather than owning up to a poorly handled situation, they chose to pass blame, make false assumptions, and contradict their own return policy. There was no accountability, no willingness to resolve the issue fairly, and no appreciation for a customer who's spent tens of thousands of dollars over the years. And for the record, I do not like to leave bad reviews whatsoever. In fact, you can check my Yelp account--I don't leave bad reviews at all. It takes a lot to push me to this point, and for me to take the time to write this, you have to piss me off at least 10 times more than normal. That's how bad it was dealing with Diego and Alexis at Resource Building Materials. To say I'm disappointed is an understatement. This is not how you treat a loyal client. If this is the new standard of customer service at Resource Building Materials, I can no longer recommend them--and will be taking my business elsewhere moving forward.
