For the most part, I was happy with Mario's work. The reason for 4 instead of 5 stars was the oven was higher than the counter about a quarter inch while the back of the oven is flush with the counter. Before the kitchen floor was replaced with laminates, the entire oven was flush with the counter, and the reason was the laminate was installed under the front legs of the oven where the floor was bare before that caused the oven front to be elevated.

We received several bids on the work we needed done. Mario Diaz Flooring was not the cheapest bid and not the most expensive. We chose them because of their ratings and the confidence Mario had that we would love the end product. Our situation was not just refinishing original hardwood floors, putting adding a brand new 300 square foot oak floor with a 70-year-old existing oak floor that flow together. When we pulled up the carpet, we had a lot of stains in the wood, some fresh and wet from my daughter's dog when they visit us, which I was not aware existed. I was amazed that Mario’s crew got all the stains out and the new room they added matched the old oak floors so well. They did a beautiful job. They showed up everyday and completed the job in a timely manner. The crew worked very hard and were very polite. A few companies that quoted the project seemed to make a big deal about adding a brand new room with the original oak flooring we had. Mario assured us we would be happy with the end product and gave us confidence in his craftsmanship. He said our floors will look pretty much the same because he uses solid oak similar to what was used in the 1950s (newer but oak). He uses a process to age the wood to help it match the original. We were amazed how the floors matched up so perfectly. They laid it down piece-by-piece (no fake wood or prefab material). We absolutely love the look of our new floors. I will never cover up these beautiful wood floors with carpet ever again. I encourage people to get multiple bids and have conversations with the companies. It is time consuming but worth the effort or just skip them all and call Mario Diaz' company. If you get multiple bids, you will figure out fast who is taking advantage and highballing the project.

Mario's provided accurate estimate of project, ordered custom maple flooring to match existing floor. Mario's team was very professional with installation of new floor and refinishing existing floor. They went the extra mile to insure we were happy with results. 70 year old floor looks amazing and the new floor matches well. Neighbors were impressed and are interested in Mario's team for their own floor projects.

Mario's people were on time and completed project as promised. 600 square feet of refinished hardwood.

I don’t often leave reviews unless something about the company/job was quite remarkable, one way or the other. This company, and the team they brought to the job, was outstanding. The quality of the work is top notch. The team is made up of well-mannered professionals. And the price was very reasonable. The hardwood flooring throughout my property sustained significant damage from tenant’s cats. It was so disheartening. I scheduled Mario and his team for the initially planned work, but once the tenants were finally evicted, we discovered the scope of work needed was much larger. Mario’s company was flexible enough to enable me to still meet my deadline. This was during the last big heat wave of the summer, so conditions were tough. But this team was nothing but professional. They really went above and beyond in every way. The finished product looks beautiful. Thank you Mario and team!

The project went really well. Mario and the employees working with him were punctual, professional and personable. They were amazingly organized, worked well as a team, were courteous and focused on performing the job and completing it to my satisfaction. The floor looks great.

Great. Mr. Diaz was responsive and flexible in scheduling and re-scheduling to meet our request. Workers showed up on time and were very professional. They protected the area to keep dust confined to the space, and cleaned up beautifully. We thought an additional coat of polyurethane was needed for appearance and Mr. Diaz did not hesitate to send his men back to do that. I rated his price a B because it was similar to a quote we got from another company--so Mr. Ruiz price was good but not a "bargain." That said, the quality of work was worth the price.

Exactly what we wanted!

Mario did an excellent job. He made my problem, his problem. Thank you, Mario.

As expecteted.

He came to my He took all the measurements and gave me an estimate. I was going to hire him to do the job becayse he sounded very kn9wleadgeable and took the time to explain and make recommendations. I ended up postponing the work until further notice.

This wasn't very good. He was supposed to come by and look but he never called and never showed up. He was going to quote me on doing wood floor installation. 

The conversation on the phone, it wasn't the friendliest conversation, but it was ok. 

They were very nice. I'd give them the best score you can, I guess. I thought the price was a little high. I think their quality is very good.

Great. The job looked beautiful!

Super job. The workers are quite nice and took pride in the job they were completing.

These guys are phenomenal! Originally had them come out to refinish the hardwood floors in the three bedrooms, and was so pleased with the quality of their work, that I had them come back for an encore performance in the living room, entry, dining room, and hallway. The house was built in 1951, so the floors are over a half-century old, but Mario and his crew brought them back to life beyond all expectations. They removed the Pergo flooring, repair a couple spots of termite damage (matching and replacing the wood), did an amazing job cleaning up where the original floor heater had been, which involved dismantling the previous repair attempt, bringing the sub floor up to the correct level and then interweaving the replacement red oak into the existing flooring (in both the hall and the living room). Great crew (Albert, Charlie, and Jordy, along with the owner, Mario Diaz), who were always punctual (actually, early), explained everything in detail, worked hard, and cleaned up nicely. They magically made the 65-year old floors look like new – and finished everything off with a matching molding that really set off an exceptional job. Could not be more pleased! Very knowledgeable, excellent work ethic, beautiful end product, and prices that are more than fair. Thank you! Gentlemen. Plan to have them do more floors in the not to distant future - incredible quality of work at a great price.

Wonderful service and workmanship. Mario was very responsive and communicated every step of the way. His crew is professional and very respectful. I am very pleased with the work and would not have any reservation in recommending this company.

Everyone I had contact with was professional and very courteous. The workers were very diligent and considerate. They took some abused floors with a very dark stain and turned them into something beautiful.

My floors (three bedrooms) look incredible, Mario, Albert, and Charly were a pleasure throughout, and their finished product defines professionalism, attention to detail, and pride in their work. An excellent work ethic was continuously displayed by these three gentlemen, as they infused unexpected new life into 65-year old oak flooring, that before their arrival, displayed a multitude of scars from children, pets, and an abundance of foot traffic. Everyone was always on time (or early), they cleaned up daily, they were respectful of the house (some tradesmen crash through your home like stampeding herds of buffalo - not so for these gentlemen - they treated it like it was their own). Threw them a curveball by asking for matching new moulding at the last minute and it magically appeared. Would definitely hire Mario Diaz Flooring again (in a second) and in fact, plan on having them remove Pergo from the hallway, living room, and dining room so that they can refinish those floors as well, and, additionally have another project in mind for next year. These guys are just incredible. Thanks! Mario, Albert, and Charly - you've transformed the house!

Mario and his crew were top notch. I called him based on Angie's List reviews. From the beginning he always called me back promptly or texted. He would call if he was going to be late, which I really appreciated considering a lot of companies don't do this. With LA traffic I was amazed at how prompt he was most of the time. 

How he works is when you call to inquire about services he has you go to a flooring show room in LA. there you can see everything that is available. There are no prices but Mario will tell you what the price is per ft after you make your choice. I'm sure you could get a price on different floors and then make a decision, I just found what I wanted and left it at that.  You can bring large samples home for 60$ a sample, which will be refunded when you return them. 

Mario's crew was fantastic. They paid excellent attention to detail and I feel like they were almost like artists in the attention they gave to their work. They are family run and trustworthy. I felt like they worked tirelessly in order to do a quality job. Mario works with you throughout the process, ensuring all of my needs were met, asking question along the way to make sure I was happy. The result is some beautiful floors in my new house.

The original quote for the job was for about 600 sq ft of flooring and the underlay. I hadn't measured correctly and ended up having to buy more flooring and the trim was extra as well as the moulding. This makes sense, but as a new home owner I'm not used to knowing there will be added incidentals. I also ripped out the carpet and carpet tacking and opted to install the moulding myself hoping to save some money but I'm not sure if that was taken into account. Organization with communication for up front costs was really my only gripe with these guys. The floors are really stunning.

Mario called back within minutes of my leaving him a message. I explained that I had a condo that I wanted to redo all the floors with laminate and tile in the kitchen and bathrooms. He was quick to say he didn't do tiles anymore. Once I told him the price I was getting from Lowe's flooring people he pointed out that the price was very good but to do my due diligence on the subcontractors that they use. All in all he was straightforward, honest and gave good advice. I don't know him well enough but I get a sense he's a man with integrity.

We bought a mid-century home with carpet and soon after closing escrow we discovered beautiful Red Oak Wood floors but they were in need of TLC.  The master bedroom was in bad shape and in need of much attention.  The rest of the house, 2 additional bedrooms, 2 hallways and a living room were in decent shape but still needed work.   

Initial contact: I emailed Mario Diaz via Angie's List, requesting an appointment.  Mario responded within 48 hours, asked me to call him at my convenience to set a meeting date.

Estimate day: Mario arrived on-time, no kidding our appointment was at 11am and he was at our front door at 11am!  He walked in and said, “these floors are beautiful” (which I couldn’t see it at the time).  He walked around and looked at every detail, we shared our interest in staining the floors to a dark stain.  My reason for staining was because I didn’t think the stains and discolorations would all come out.  Mario discouraged us from staining them, which by the way I am thrilled we took his advice.  We also had termite damage in one bedroom which Mario assured me I wouldn't be able to tell where the damage was after the job was done.

Mario provided us with a detail estimate of the work one-day after the walk-through.  The estimate was very fair and we hired him.  We had a few other things going on at the house so we asked to push the work back a few weeks. 

Project day:  Mario and crew arrived on time and started the work immediately.  All floors were completely sanded at the end of day 1, and on day 2 they were cleaned and the first of two top coats was added.   I was then able to see Mario’s vision, my floors looked amazing!  We are very happy with Mario and crew, they were all very professional, respectful, punctual and clean! They cleaned at the end of the work day which is very important considering the amount of dust this job produces.  I also want to mention that one room and one hallway have parquet floors, and those were sanded by hand in order to maintain the integrity and style of the floor.

We are very happy with the outcome, our floors look amazing, brand new and yes I cannot tell where the original stains and termite damage was!!!  Thank you Mario and crew for a job well done!!!

.Mario and his crew refinished the oak floors of my father's 1950s home. About 950 SF, total of two bedrooms, hallway, dining room and living room
We pulled up the carpet and found some beat up hardwoods that I wasn't sure could be saved. Mario came and quickly determined that the floors were in great shape and might require minor repairs or replacement if their treatment techniques and sanding was unsuccessful. I was skeptical. I asked whether we should stain the floors as well, to which he strongly discouraged me. He recommended sanding the floors and refinishing with oil based polyurethane, and said that the floors would look great and last much longer without any staining. Even though staining would add considerable additional cost, Mario still discouraged it.
I trusted his judgement and was rewarded for it. Only a few spots needed replacement boards with only minimal cost impact (a few hundred dollars). The total job came in at $2,450. Extremely pleased and have recommended Mario to several friends already.
