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.

Contractors' Warehouse has many home construction products available. I came for bathroom lights,…read moremirrors, and towel racks. They have diverse options that are nicely labeled on the display and inventory section. The prices for some items are better than Home Depot. However, prices for cabinets and counter tops are more competitive elsewhere. Most stores nowadays only carry modern options, and here they carry the not-as-trending models too. Brand wise, other stores carry more options. For example, I didn't see Pfister or Kohler facets. Although the aisles are nicely labeled, it was hard finding my way around to the sections I needed without asking. Even then, not all employees knew exactly which section had the items and would give a range instead. I recommend monitoring cashier behavior. My cashier gave the impression of lacking respect for customers. She kept talking about food and lunch orders with the coworkers, looking at her nails, ignoring me as I waited at check out. It was not until I asked a third time if I could check out that I was acknowledged. Additionally, I was the only customer at checkout... I hope to see the checkout experienced improved for the future.

He assessed the problem and figuered out it was rubbing against a previously installed door jam. He replaced the worn rubber weather stripping fixing the problem and fixed the door jam. Fast, efficient service, Terry is a super friendly, nice guy which is why we patronize this local business. Outstanding service. Highly recommend D. P. Door!!! No delays, no hassles! Thank you Terry!

Have you ever met a super friendly, and clean construction guy? Me neither, until I saw DP's guys in action. This company employs only the best installers, who are family guys and courteous. They clean up their mess when they are done! As a local Realtor, I'll refer this company in a second to any of my clients looking to remodel their home. If only there were more businesses around the Inland Empire that are run THIS well. Yelp- Why are you filtering out my legitimate review?
