I'm so glad we found Diamond Construction. After a long search for a trustworthy general contractor…read moreand being extremely selective about who we work with, finding Justo truly felt like hitting the jackpot. From our very first inquiry, Justo has been incredibly responsive and reliable. He's clearly a busy man, but he makes the time and actually shows up. If you've dealt with contractors before, you know how rare that is. He follows through and does exactly what he says he's going to do. He stands confidently behind his work, which immediately gave us peace of mind. I'm very particular. It's simply in my nature. I ask detailed questions, I research everything, and I pay attention to the smallest things. Justo has been nothing but accommodating every step of the way. He answered every question thoroughly, never rushed the process, and never made us feel like we were asking too much. His knowledge and professionalism genuinely stood out, and you can tell he takes pride in delivering quality work. We initially reached out because we had a leak in our garage and needed our roof repaired and had contacted several other companies. What really set Justo apart was the balance. His pricing is fair and reasonable, yet you can clearly see the confidence he has in his craftsmanship. There's no pressure or gimmicks, just honesty and solid work. One quick tip: the phone number listed on Yelp is a Yelp-generated number. If you want to connect quickly, use the "Request Consultation" option on Yelp or visit their website for their direct contact information. Give Justo a chance to earn your business. We genuinely feel lucky to have found him, and we won't be going anywhere else. Thank you Justo and team! :)

I recently (10/2025) hired Diamonds General Construction Co. to replace the carpet in my bedrooms,…read moreand I couldn't be happier with the results! I had the pleasure of working with Mr. Justo, who was incredibly helpful throughout the entire process, from answering all my questions and scheduling my free estimate to making sure everything was completed smoothly.

We called multiple turf companies and most wanted a deposit just to come to our house in Tehachapi,…read morethe only one who didn't, was JNR. They were so helpful and they let us do our meeting online to save us time and effort. The price was a bit more than other quotes we received, but the quality and professionalism or JNR was outstanding and totally worth it. All the other turf installers gave us a wait time of 6 months! JNR said it would take about 4 weeks for installation, which was acceptable. Two weeks went by and we got a call from JNR asking if we would like to have the turf installed in 2 days! Needless to say we were very happy. When the crew came to our house, they were professional, friendly and courteous. The guys answered all of my questions and I could tell they knew what they were doing. It was a pleasure to have them at our house. I've already told my friends and when we are in the market for turf installation again, JNR will definitely get my business! Thank you JNR!!!

RNJ was the only one…read morewho provided a timely response to view the project in person, provided a detailed estimate, explained the work to be done, and was able to provide a time line. We used RNJ a few years ago for a turf project at our old house and were very happy with that work, so I knew choosing RNJ for this project was the right choice. On construction day, the work was performed as explained. The project took only a day and a half and looks great. The cost was reasonable for what I wanted done. I will defiantly hire RNJ again.

She was patient and professional with us and walked us through the entire process and helped us pick out fixtures and details that turned out perfect. Once we signed the contract they jumped into action, they immediately scheduled us the following Monday and were in constant communication as what each days work would entail and they never missed a work day from start to finish. They were always professional and friendly. If we need something done again we will not hesitate to use the Lenton Company!

Early on in the project I met with Lenton to make cabinet, paint, tile and decking selections.

I have never had a contractor clean up as well as they did. They did a great job of communicating and also coming out to check on the project milestones complete. There were a few concerns I had, they were immediately addressed and resolved to my liking. I definitely recommend Lenton for any project!

If I could give them a NEGATIVE 5 stars I would!! I don't know which if the two is worse, but then again they are brothers. I am so disgusted I don't even know where to start. The constant lies to our face, promises that they failed to keep, left us high and dry even though we demonstrated patience beyond comprehension. The constant begging for money because otherwise they "would have no way of purchasing material to continue with our projects." The dirty pig mess that they constantly left when eating lunch or each and every time we provided them with food and drinks, they would leave cans, bottles, fast food trash, bones l, cigarette butts and trash all over the front and backyard despite our messages asking them to use the trash cans. Not to mention piles of hardened cement bags left on our driveway that they refused to remove and blocked our driveway for over 1 year. Our shotcrete pool filled with mildew swamp water, mosquitoes and tadpoles that ALDO told us we were responsible for purchasing a pump to remove the water that accumulated for over 1 year!!! Constant sob stories that they have no money and blamed COVID. Yet had they stuck to the timeline the COVID prices would have never been an issue. Instead they trick you by completing the dig and rebar quickly then leave you to a bunch of excuses like their truck breaking down, being sick, family members passing away, being deported, getting wounded at other jobs ...are just a few that come to mind as I type this. They made decisions without consulting us and we had to repurchase material due to their error and lack of consulting with us. NOT to mention the waste of a backyard filled with concrete, which was ruined with the MOST crooked lines, the most crooked stamp job that even a child would notice, misplaced drains that sit above or next to the grades so the the drain can't even do it's job, AND not enough drainage. Our front lawn ruined, so now we have to pay to replace because to this day we have piles of cement gravel that they just leave lying around not allowing for the sprinklers to be turned on because the cement piles are sitting on top of the sprinkler heads. We are going on 2 years and our pool project is not even close to being done!! After begging for another payment they leave us high and dry after nearly two years (two years April 2023). Out contract includes a shower and exterior restroom which were never started, they never dug out the drain to the street, so it ends next to my residence which could cause structural damage, contract includes salt water pool, they never told us they did not purchase salt water system and to this day have a chlorine system. Our fire wall does not have keys installed or the grates to place fire rocks, our fire pit does not have grates to hold fire rocks either, so they both sit empty with piping exposed and cannot even be used for their intended purpose. They installed a side gate incorrectly and had to redo it. The drilled so many holes it's riddled from having to redo it. That same side gate falls off whenever we open it, so we constantly have to put it back up, no auto fill installed to this day so we have to use our hose to constantly fill it, the filler between coping and cement is still sitting there to this day with the styrofoam mesh stuff, our spill waterfalls are cement and to this day have not been replaced with flagstone that we purchased. They even asked us to buy the blade to cut the flagstone and they still have not cut it and placed it, the slab is still in our yard. Not to mention the extremely poor workmanship on the stack stone surrounding our pool and jacuzzi, poorly placed stone that sits in top of our fire wall and fire pit, which I forced them to redo. The cement that is oozing from the bottom of those stones that I can see from the underside while in my pool. The salt water pool tiles for our CHLORINE pool were installed CROOKED and uneven! The grout in our jacuzzi is half gray and half black which ALDO said just needed some acid to make it match. We bought the product to supposedly fix it but ALDO didn't even take the time to fix it.

They cleared the water damaged and replaced the drywall so well it doesn't even look like we ever had an incident. The rate was very reasonable, too. We did have to make a deposit first, and then pay final payment when the work was complete which I expected and is fair. Overall we are VERY pleased and will use him and his services again.
