M&M did a great job. We had a leak from a previous welder. After M&M finished the work, there was no more leaks. Thanks Mike

I contacted M&M Portable Welding and Mike returned my call right away. He answered all of my questions and was very upfront and honest about his services and pricing. If you want the best possible services in the area, this is an excellent company do business with. Friendly, professional and very knowledgeable.

Mike helped me out a bunch when fixing the frame of my motorcycle. Now I'm able to get back on 2 wheels! Definitely recommend

Christian Norwood Via Google Review

I would give 10 stars if I could. I was traveling with my wife in our 35 foot fifth wheel. About 2 hours from home I snapped a leaf spring and disabled it from being able to be pulled. After spending all day and trying to arrange a low boy tow I was told now a tow would not be out until Monday and it was Saturday night. We were left stranded. After a suggestion to find a commercial welder I found Mike online and about an hour away. He answered right away and responded within 20-30 minutes. Mike and his partner responded, and were able to weld the spring back to the proper position. We made it home babying it at about 30-40mph. We got back home around 1 in the morning and the weld was still holding. Mike saved us we were completely stranded in a bad part of town with no resources. Phenomenal work and customer service!!

M&M Portable Welding did an outstanding job. Mike’s crew was on time, communicated well and completed the scope of work in a timely manner. I will use them again in the future and would recommend them to other contractors.

Lee Rothrock Via Google Review

Amazing experience! Mike was quick on the job and went above and beyond the work that was required. He was very kind and reasonably priced given the scope of the work!

Robert Preston Via Google Review

The frame bracket that holds my gas tank to my 50-yr-old motorcycle rusted off (I guess that's what 50 yrs does). I was looking for a portable welder to come. Mike called me immediately back, but was very honest that he does larger size jobs and it would not be worth the cost for the work that he does.

Appreciated the honesty and the fast response!

Milton L., Los Angeles, CA Via Yelp Testimonial

M&M Welding did an amazing job! Mike was very accommodating and easy to work with. The quality of the weld was excellent and his price was very reasonable. I would definitely use him again and highly recommend him for anyone. Thanks Mike!

Jendayi Saada Via Google Review

Expert knowledge, Truly one of a kind service. I called and left a message and Mike replied incredibly quickly, I was very impressed. I am a young DIY enthusiast working on my Truck and came across an issue with some bolts seized into the block of the motor. I called and asked him for possible help or advice, he was kind enough to thoroughly explain what he would do, and wished me luck, didn’t charge me at all, and I was able to solve my problem. Experienced, kind, to the point, solid.

Garrett Westton Via Google Review

M&M Welding is a company I would not hesitate to call again for any welding that I need done, Mike is very friendly and straightforward. Was at my house at the time he said he would even though it was a holiday weekend. Just remember good work is not cheap and Mike only offers good quality work.

He was able to do a difficult job with ease! I HIGHLY RECOMMEND him. Also he's funny.

Agustin Floriano Via Google Review

Mike is great to work with! I called M&M welding because we needed a hitch receiver welded on the back of our vintage trailer. I had been having a hard time finding someone local to LA. who was responsive. When Mike responded to my Sunday email with a personal phone call-- I knew that this is a guy who takes his business very seriously. We ended up driving out to him with our trailer. He is clearly a perfectionist (in a great way) to get the job right. He ended up needed to improvise on the job because of something I had noticed. He was flexible, very fair on price, and just a genuinely nice person to work with. This is a great business to work with!

Rebecca Watson Via Google Review

Had a multiple cracked bumper needed welding asap and M&M got me in right away. So appreciative for the quick response and excellent work will be coming back for future projects.

Breezy76 Via Google Review

I would say responsive and professional were the first two attributes that came across over the phone immediately after calling on this Memorial Day weekend. Straight up no B.S., while everyone else said they couldn’t help because they were leaving early for the holiday weekend and wouldn’t be able to help until the next week, this guy changed his plans to help. This is what’s missing in this country, guys like this, good quality and Good value were the finishing touch of an already solid individual with grit and know how, where have these type of people gone, there used to be more of them. Cheers,!

Jon Armstead Via Google Review

Great service! Quick! Called him and was able to take care of the welding I needed done the same day! Will be doing business with M&m again in the future. 10/10 would recommend for quality aluminum welding

Eduardo G., Garden Grove, CA Via Yelp Testimonial

We had a unique situation, traveling to events with a custom promotional vehicle. One of our hydrolic welds broke on the platform and these guys fixed it perfectly. Very professional, prompt and effective. Thank you for fixing our problem. They are an experienced team.

Diane Williamson Via Google Review

So thankful to have found Mike and M & M portable welding! Our fifth-wheel broke and needed a spring-leaf hanger welded back on. Mike was professional from the moment he answered our call and throughout the entire process. He was able to come to us and fix our trailer by the next morning. It was not an easy fix, but he remained patient and diligent to solve the problem. He did an incredible job, and above all, gave us peace of mind and ensured our safety. We recommend him and his company for any welding job and it was well worth every penny!

Ama Wafer Via Google Review

Mike took time with me to find best way to tackle the repair . Also I call him my first time contacting him and 2 1/2 hrs later the job was done ! He actually reinforced the repair so that it was better than new condition. I'll use Mike whenever I need welding and I highly recommend him . Paul Stearns

Carolina N., Covina, CA Via Yelp Testimonial

If you're looking for someone honest who is not going to BS you, or rip you off, Mike is the guy you want. I called him today explaining my plumbing and welding problems which are numerous. Mike knew that he couldn't come out to the house because I live sooo very far away from him but he spent a great deal of his time on the phone with me (and it's Sunday.) I sent him pictures of my bathtub drain and overflow drain which I thought only needed welding. After discussing what the "plumber from hell" did, (breaking through my bathroom and kitchen pipes,) Mike gave me suggestions as to what the problems might be and gave me the name of someone nearby to call. I wish that I lived closer to his company because in this day and age, one can easily get ripped off. Mike is the one to call for all your welding issues. Thank you so very much Mike for taking the time with me and talking me through this mess of horrors. He's listed #1 under the Better Business Bureau of welders.

Eileen Evans Via Facebook Review

Called Mike late on a Saturday evening after our original contractor cancelled. He assessed our situation based on a few photos and description, and gave us a quote. He showed up on Sunday at the agreed time and brought all equipment needed for a welding job at the middle of a parking lot with no electricity. He carefully inspected and everything and then did a very thorough and expert job. We felt we were in good hands and felt confident about the results (unlike with contractors we worked before). We would work with him again any time.

Viktor Schmidt Via Google Review

He did a very great job did exactly what I needed which seemed to be impossible but he made it possible highly recommend this man

Andrew Clark Via Google Review

Mike is a true craftsman and a very talented welder. Today I had him repair an aluminum part for my boat and he did a fantastic job. The entire interaction with Mike was smooth and he was very personable . If you need quality welding and like honest people (Mike ) is your guy.

What a great bunch of guys. Was moving from Palm Springs Ca to Northern Ca. when a borrowed trailer tongue broke at 7AM on a Saturday. I called Mike and we talked. I sent him a few picture then he called back and we discussed the details of my problem. 20 minutes later they were on site with me and in less then an hour I was back on the road.

The boys are very knowledgeable , professional and courteous. Thanks again Mike for the helping hand.

Edgar Aviles Via Google Review

Mike @ M&M welding is absolutely fantastic and very easy to work with. He helped our University team out of a very tight spot so we could continue to compete with our vehicle. He welded our aluminum frame up very quickly and the quality of his work was beautiful! He arrived very quickly after our call for help. His equipment is all top notch and very well maintained. I am a professional mechanical engineer and I know good work when I see it. M&M is the best in the industry!

Matt Thor Via Google Review

I found M&M welding on a random google search and was so happy I found them! When hiring a company for such a big job, it's always nice to have a recommendation but in my case I took a chance and consider it hitting the jackpot. The owner mike was so on top of it and his team blew me away with her sufficiently the job was done. I highly recommend M&M Welding. Thank you to Mike and everyone else for doing such an amazing job!

Suzanne M., Los Angeles, CA Via Yelp Testimonial

M&M Portable Welding welded a set of fixtures for one of my major projects for Karma Automotive in Moreno Valley. They were they only firm that I was able to get to come onsite at a short notice.

They did an excellent job, went above and beyond what I expected and got the job done ahead of schedule.

Landus Cox Via Google Review

Mike took on our tricky job to repair a manufacturer's defect on a sliding door system. He and his crew made an extra second effort to TIG weld a portion of aluminum that was hard to reach. They were clear about the cost and the scope of the work.

Mike @ M&M welded on my mulch blowing truck today. He nailed it. He made sure I was happy with the position and angle of everything that was being welded. Welds are strong, no corners cut. Was at the job site right away and got my truck back up and running right away. Super happy with his service and I'll be calling again if needed.

"Prompt, Reliable, Progessional Service. I talked to Mike about the job that needed to be done same day and he asked me to take some pictures of what i want him to do. He called me back in a few minutes after i send him the pics. He told me my options as far as how to get the job done. I told him that the job site is in a high school and he is required to be LA Certified and insured and bounded. He assured me that he has all the certifications and also he is well experienced over 39 years. It was like a miracle coming through. I schedual an appointment with him for 6:00 Am next day. I got a call from him at 5:52 Am that he is at job site and ready to get started

After checking his certificates, he started and finished within the promised time frame. I am very pleased with his professionalism and prompt service and i am very happy to use him in the futuer. I recommened him very highly to others. Thank you Mike."
