I have called Diamond Environmental twice now and they have been awesome! I requested next day or service two days later and they have always been able to accommodate me. Both times that they have been out, each tech was very helpful and courteous. Went above and beyond to make sure the tanks were emptied and everything was running smoothly. I will definitely be calling them again. Also, they drove a pretty good distance to my home and for what I thought was very inexpensive!! Thank you so much!! read more

We started using them in 2024, for a few smaller jobs,They were great. In 2025 we used them for all of our jobs, totaling 31 different events. Our July 4th event hosts 45k people, we shut down streets, fencing, bathrooms, and even water krails. they were amazing. angel and his team worked so hard. They were on time, they were polite, they listened, they hustled, then on tear down, they showed up and got it done in 2 days. It is a 4 day load in and a 3 day load out, yet they finished in 2. Stacy our rep was great and Maritza our billing agent was amazing. I cant recomend them enough. read more

My company has a corporate account with Diamond and I use them for a variety of services at our job sites. Their account reps provide phenomenal customer service, especially Heather R. in Contract Support. She always handles our needs and even if the matter isn't in her scope, she gets me to the right person. So happy to have her! read more

Diamond Environmental Services came out to pump our septic tanks on a residential property in Escondido. They were able to quickly uncover the lids and pump the tanks the following day. They showed up on time and were very respectful of our property. We would gladly call them again for future septic tank cleaning! read more

I'm very happy with the service I received from Diamond. Scheduling was easy, service was timely and thorough, friendly staff from office to technicians, efficient and professional. I really appreciate Felicia who I worked with on scheduling and Silvo who came out to test and pump the septic system. Thankful for local folks who care about what they do and put people first. read more

Septic tank pumping I knew this guy they sent was lazy when he had issues taking the tops off. I had to do it for him and it wasn't even that hard. Then he didn't even pump the tank out totally. Made it seem like some of the waste was to hard to move. But it was moving when he used the long rod with the square end. He just didn't want to take the time out to do the necessary work. Then when I told him I was going to complain to the company about him doing half the work he said, good luck with that! I guess there's no good service providers and the owners dont care. I wont use Diamond for septic pumping again. Previous past pumps they always did a very good job. But the guy that came this time was very nonchalant always saying, I'll do my best. Sorry, but if that's the best he shouldn't be doing this job. read more

This company damaged my Tesla by knocking a construction fence over and on to the street, clipping my car. They refuse any liability when my Sentry videos clearly show their employee doing the damage. We provided Safety manager, Pablo Martinez, our videos and contact numbers. He was rude and disrespectful to call the homeowner and tell him not to pay us a dime, that it was from previous damage. Only a dishonorable man and dishonorable company would NOT provide their insurance information to determine the real truth. read more

Once again this business did not let us down. Kristy Garza was very helpful and professional to assist us with our carnival bathroom needs. They were very punctual with the delivery and pick up, even called to make sure someone was there to receive the restrooms. We will definitely use them in the future and I would recommend them to anyone that wants to deal with a professional company with a great costumer service provided by Kristy. On August 26, 2023 we ordered 10 Porta Potties and 2 handicap Porta Potties which were very clean. They also came out and service them which were left smelling fresh and clean. read more

Don't trust these guys. They damaged my gate while removing a porta-potty and refuse to take responsibility for it. The Safety Manager, Pablo Martinez, has been particularly rude, ignoring my phone calls and trying to convince me that the damage already existed when I witnessed the event. There are better options than this disrespectful company. read more

Awesome service, had the potter potty for a year now and no issues, they always come and clean it once week. Maria Martinez was a great help when I was ready to cancel my services. read more

They can HANDLE STUFF! Thanks Judy and Ruta.....Construction West needs you! Jeff Brand, President Construction West PS: You two keep Diamond "sharp!" :-) read more

Our portable restrooms needed service within 24 hours, and it's very unlikely for it to happen over the weekend. Spencer handled my frustration well, and was able to schedule it yesterday. Having 4 groups of 50-100 people this weekend would have been a disaster if the units weren't cleaned and stocked. read more

As a contractor, having a reliable company to provide portable restrooms, temp fencing, etc is very important. MARIA MARTINEZ helped me today and was very efficient. I was disappointed to find out that Diamond no longer offers same day deliveries as that has been helpful to me in the past. read more

I have been using Diamond since I stopped using United Site Services about two years ago. I wanted to work with a local San Diego company with real customer service after being completely burned by United. Diamond has real people that answer the phone when you call. They strive to offer the best pricing and service that they can. I had a problem with delivery of a portable toilet to my residential job site. I have employees and I have an obligation to my guys and my clients to provide a restroom at every job. I ordered the unit early so it would be available when we started the job. When we got there it was nowhere to be seen. I called and asked that they remedy the problem as soon as possible. The customer service person, Judy Ramirez called me back promptly and explained the situation. In the end, it was frustrating and we ended up not getting the portable restroom delivered to the job and made other arrangements for my employees. This would usually not result in a positive review from me, but Judy Ramirez made sure the charges were reversed, gave me her direct line to contact her in the future and her attitude was positive and represents a company that wants to keep my business. I work with hundreds of businesses as a contractor and I can tell you that customer service is a lost art. Every company makes mistakes, but it is what happens next that matters. Making the situation right with me as a business owner is what I expect from anyone that wants to keep my business and it is the same way I run my own company. The world is full of companies that offer everything and deliver nothing and I am impressed with Diamond Environmental and grateful for Judy Ramirez! read more

I have worked with Diamond for many years. They have done everything from daily restrooms to monthly rentals. Kristy in there San Diego office is a rock star!

Called Diamond today needed some quick information and a variety of other things. Lucky for me I spoke with Kristy Garza. Her attention to detail was impressive and her customer service skills are excellent. She is a fine representative for the company. Kristy is awesome, knowledgeable and a dynamite personality! Will continue to use this company again and again! Way to Represent Kristy! read more

Was ok with them up until about 6 months ago when their service and quality went to the black tank. I'm full time 5th wheel and rely on them to service the blank tanks. They have switched service days on us without telling which caused a big stink (literally). They continually step on the gray water hose causing it to crack. They broke the handle off my main valve. But the big one was recently, bending the black water release rod (I watched that happen) Keep in mind that when this happens, that rod will not open or close. At that point when I asked the driver what they were dogging to do to solve the problem, he got into his truck and left. I called the office and talked to a supervisor and he said that this happens but there is nothing he can do to help. So now, I'm out close to $799 to fix it. And get this, as I type this, I have 2 RV techs standing around waiting on Diamond to come empty the black tank. I even agreed to pay Diamond's additional fee of $75 to expedite the call. Hey Diamond, maybe next time this happens to someone else, stand up and take some responsibility! ***Update*** after waiting for over 2 hours past scheduled arrival, the driver didn't have the right adapter so he had to go back to get it. After paying the techs to stand around, this whole debacle they caused will cost me over $1000 read more

Requested a portable toilet. Maria Martinez was very helpful and took the time to review my options. Service was good, and efficient.

make sure you get an accurate quote before you provide billing and personal information. I contacted this company yesterday and requested a quote for a porta potty. I was given a specific price for 28 days. Also, the delivery and pick up fee, the price was good. Customer service gathered all of my information, including my drivers license and address and when she went to run my card, the numbers did not add up. she explained only at the end that I would be receiving two invoices one for the prorated plus delivery and the other for 28 days. The price went up just over $70 because they would not be billing me from 28 days of the time of delivery, instead they would wait seven days before the 28 period started. I nicely declined and explained that there were several other companies that were less money. She got upset with me, It seemed, rather short... it felt like deception and misrepresentation to me read more

Working with Diamond and my account manager Kristi could not have been better. Her attentiveness to every detail for my large event was exemplary and was able to anticipate my every need and communicate clearly with me every step of the way. On site, Diamond's crew were very professional and pleasant to work along side. Everyone from start to finish provided excellent service. Diamond was able to handle a large majority of my event needs all in one place very competitively so I didn't have to go chasing around a bunch of different companies for services they ale ready provide. I am glad I used Diamond for my large event over a Father's Day weekend and will be contracting their services for years to come. read more

Diamond provides porta potties and hand washing stations at all the JFS safe lots. They sold them saying they had great customer service yet the hand washing stations never have sanitizer in the grey water tanks of the hand washing stations smell awful. There has been a missing soap dispenser and a broken one at one of main porta potty stations. Though there is COVID going through the lot there hasn't been any way to wash hands at that the main porta potty station for over five days. Though I talked to the guy who services he says he isn't allowed to fix them without approval. Though they empty the porta potties they don't clean them, they don't spray down the handles or doors. It's really pretty gross. read more

Very pleased with everything! Kristy went above and beyond to help me choose the right restroom for my event and even worked with me since it was going to be on dirt. The unit arrived in excellent condition and was exactly as described. My guests were all pleasantly surprised with it :). I got the Solar Elite unit and it looks like an airplane restroom with a sink, mirror, light and flushing porcelain toilet. I just wish the instructions indicated that you have to lock the door for the unit to turn on - a few guests thought it didn't work lol. read more

We are on day 2 without water in our pool. The drivers are working as quickly as they can, but the demand is too great for this many people.

Maybe a reservation system should be used !!! read more

Ease of scheduling a Porta-potty! Delivery was on time! Service was like clock work, and the pick up date was perfect! I had it for over 3 months while there was a renovation at my home. I would use Diamond again! read more

They have 3 stars for a reason....This is the worst company I've ever had to deal with. I've had multiple problems with them from day one. The women in the office have no idea what they're doing, they give different pricing for everything. They don't schedule anything correctly. I called multiple times to find out what happened with my service and each time they had no record of my calling. They are untrained and irresponsible. I gave them specific directions, twice, on how to enter my property and where my RV was located and each time they had no record of me calling. They have the WORST CUSTOMER SERVICE AND COMMUNICATION EVER and on top of that they don't apologize or acknowledge problems which is why I'm guessing they have so many problems. I have spent hours trying to get simple services set up in addition to the time I had to wait for them to arrive/not arrive, the call backs, complaints and waisted time. When I finally got them to come out they didn't dump the rv.....the driver just left and CHARGED ME! In addition to that they quoted me 2 prices $65 and $50 but of course my instantly emailed billI was for $80!! I had to call back ONCE AGAIN.... 3 x's before I finally got an answer. "We see there's been multiple problems with your account so we are going to have to part ways" Hahaha, ok I was calling to cancel anyway, but ok...it's my fault? They're right, my fault I didn't cancel after the first problems where the untrained office woman quoted me a price of $160 then come to find out it was actually $190 and yes I know there's a drop off fee...this was the monthly rate. Either they're extremely dishonest or extremely incompetent. They will say I was upset and mad and yelled at them when I hung up the phone .....well obviously! STAY AWAY! You've been warned!!! read more

I use Diamond quite a bit for portable toilet rental and they have always treated me really well. Multiple times for home improvement projects at my home as well as for my house painting business especially during this past year of pandemic uncertainty. The homeowners I work for really appreciate the option not to have us in their home to use the restroom, and no problems at all with delivery, servicing or pick up. Pricing is consistent and I use the auto pay option that really simplifies billing. They are a local company, not a national chain, which I really like. Yes, they have had their issues in the past and like all of us, have had to figure out how to operate in these Covid times, but they continue to provide me with excellent service. read more
