I only trust Diamond House with all my plumbing and construction needs! Joshua always goes above and beyond not just for me but anyone I have referred to him. He brings amazing value and knowledge to any problem or project you have. He actually looks out for you and tries to save money where ever he can. Don't hesitate definitely reach out to his team, they are exceptional!!

DO NOT RECOMMEND
We hired Diamond House Plumbing located in Riverside in Aug 2023 to install a leach field for our septic system, and it has never worked properly since day one. Despite multiple repair attempts, the system continues to fail, with water returning to the tank instead of reaching the leach field.
When I requested proof that the system was functioning (such as a visual inspection) one of the owners Joshua Miller, refused. Instead of standing by his work, he denied responsibility and ignored our concerns.
I filed a bond claim due to their failure to provide a working system, but the company falsely claimed the job was complete-even though it wasn't. The bond adjuster confirmed they were required to provide a two year warranty, yet Diamond House Plumbing failed to do so.
If you are considering this company and their finance company Foundation Finance for a major plumbing job, beware. In our experience, they do not honor their obligations, avoid accountability, and refuse to provide proof ad will falsely proof of proper repairs. I would never recommend this company to anyone looking for a reliable and ethical plumbing service.

If you are looking for a reputable company for your plumbing and septic needs- congratulations you have arrived to the right place! When our septic system required new pits Joshua and his team stepped in to help! This project required our driveway to be completely torn up to access the old pit- decommission that one and then replace with two more pits to meet code! I do not know anything about septic systems- Joshua explained the process step by step- he eased my concerns on such a large project! Damian was on site to do the repairs- let me tell you- he was at our house every morning before the project started to answer any questions and was timely in completing this project. Finally came the replacement of the driveway- Joe and his team were so great- all these men worked so hard from start to finish. I would give 10 stars if I could. These projects are scary ! I tell you- you can trust these guys- they help with financing if u need that and qualify. You can expect great communication with this company. Be good to them if you engage and decide to do business. These things can be very stressful- just remember at the end of the day they want to help you and they are good people! So be nice !

My project for septic tank was to take 2 months. Two weeks into the project they hit a gas . They were given the property plans at the beginning of project They then wanted to charge 10,000 to move line. OVER price. Terrible communication with foreman. I wouldn't recommend this company to anyone. My septic tank wasn't completely until 14 months later.

We had a burst pipe in our backyard while we were out of town. Josh Owner of Diamond House plumbing came out and said, that we needed to repipe the entire inside and outside of our home.
Otherwise he could fix the pipe but the next weak pipe would burst down the road. I asked how much this would cost.
He quoted me $38,925.00 I asked if they had financing, because we couldn't afford to do it otherwise. He asked if we could pay 50% up front and I again said no. Without finance we could only afford to fix the one pipe. He took my information for to see if I qualified for a loan. I explained that my husband had some health issues and missed some payments because of it. Even though he was all caught up his credit suffered a good score. I said that my credit was pretty good, however my husband was the one bringing in the income. Josh placed me on a long hold and would he came back on the line he told me I had been approved for 100% of the loan with monthly payments of $570.00.
The loan documents were sent to me and I signed everything. I told Josh that we were getting on a cruise ship the next day and that I would be unreachable for one week. I left him both our adult children's phone number in the event they needed to speak to anyone. ( they never tried to call either of our adult Children). About 3 days into our cruise I got an email that they needed to add my husband to the loan, because he was the one who made the money. I told the receptionist that my phone wouldn't be able to call out until the next day when I got to port. I phone them the next day and she said they would only do the loan if my husband was added. I again explained that his credit was less then good and she said that okay they just needed him on there for proof of income. We never heard anything from them for the rest of the trip, so we just assumed everything was good
When we got home I found our very clean house now covered in a very thick Sheetrock dust and our air conditioner no longer would come on.
Two days later Josh came to our house and said that we weren't approved for the loan. They had continued working knowing there wasn't a loan in place even though I told Josh before they ever started the only way we could do this was if we had 100% financing.
I wasn't happy that they hadn't waited to do the work until they could reach me.
Our house has been left in shambles holes everywhere which Josh told me before they started in his exact words they would take care of all the drywall.
I have exposed copper pipes running up the back side of my house. They charged over $4k for an ugly exposed water filtration system that's not even plugged in. When I asked Josh about this, he said they could run an Extention cord. We have zero water now to our front lawn and mature ficus tress my gardeners said they disconnected those lines when repiping. Josh said every pipe would be replaced inside and out. Now my lawn and tress are going to die. The shattered a double sink marble vanity several outlets no longer work in our house including some bathrooms. Josh has been trying to strong arm us for medians payment. I again explained they should have done the job until they could have spoken to me about not having a loan.
He said they will not fix any of the damage done to our house until they have 50% we have tried to get a credit line, but are having trouble. We paid they $2090.00 dollars this month that was all that we could swing. $90 was a credit card surcharge which is illegal in California. We are planning of making payments each month until we can find a loan. We feel very tricked, conned, scammed into doing a job that we told them up front we couldn't afford with lout getting finance. They should have stopped work immediately when the loan didn't go through. That in itself should be illegal. On top of the stress of my husband's illness we now have this financial hardship added to our stress. That should have never happened.
Don't trust this company they are shady.

Overpriced and didnt completed job as expected. Over 1300 to replace a kitchen faucet and LED component died within a year. They shipped another unit under warranty but since i wasnt available and declined for them to come up at the time, once I was ready they wanted to charge the full installation price for the product the sent. Dont use!! Inexperienced!

To be honest
This is the only service that i use and they a really reliable and on time.

I was minding my own business when a FREEKIN' HOLE 20' deep opened up in my front yard. Yikes!! Turns out to be a septic tank that a former owner neglected to properly abandon (jerk). In Yelp I browsed all the septic tank companies but all worked on existing operating tanks. Then I found Diamond. They install AND service AND un-abandon tanks.
The Diamond crew sent a camera in into the abyss, gave me reasonable quote, and wow did they do a good job. Some 30 tons of fill dirt is now occupying the space formerly empty under my front yard. Mrs. Yelper no longer fears being swallowed up.
Tragedy averted! Cost some coin but totally worth it for the quality of work. I highly recommend Diamond.

Today we had the BEST plumbing experience.
with Dominick Campos. He was very polite. He wore booties inside our home. He was very knowledgeable about his assessment of our drain issue. We were provided 3 written options to resolve it. He left the working area clean. We appreciate his time and will definately be calling Dominick back to resolve our future plumbing issues. Bottom line we were very impressed with Dominick!
Patsy and Joe

We discovered a leak from our son's bathroom on Saturday morning coming through our ceiling on the first floor. Very upsetting to wake up to this on a weekend. We called Diamond House Plumbing, and a service technician named Jorge arrived quickly. He was very courteous and professional. He reviewed what he would be doing at our home (leak detection) as well as the cost. Jorge was very upfront and honest. We had a good experience with Diamond House Plumbing and highly recommend them to anyone.
