What Our Customers Say

Real Results, Real Reviews
Trusted by contractors, equipment operators, and businesses across Thurston County.

As a general contractor in the remodel construction industry it isn’t common that we find a company with the ability to give you exactly what you need, the first time, on time, with great integrity and craftsmanship. I will continue to call upon Arc Tech Enterprises LLC

- SEAN ALEXANDER

Arc tech is great. We had a dif lock go out on our Garden tractor and it drove a gear through the case. The aluminum welds look great and are holding strong for over a year now. Saved us loads of money not having to replace the dif.

- Jacob Blurton

11 out of 5 stars 🌟 I can not say enough. Lance has a professional attitude, is extremely knowledgeable in his craft, and takes the time to communicate in detail what he is doing so that you are not left in the dark. He is honest, trustworthy and fair.

I had Arc Tech do some work on my son’s 2002 F250. The short version is that a mounting plate that was welded to front axel broke and needed replacement. I’m not going to spend my time here describing the repair other than to say that the repairs were more than I could have asked for and he found some other issues and fixed those for me as well! What I want to talk about here is the type of person the owner Lance is. By all appearances he is a capable craftsman and a very responsive business owner. He was quick in responding and coming out to look at the job. His communication through the process was exemplary. The pace of getting the work done was so fast that I wasn’t ready for it to be done as fast as it was. His bids were accurate without adjustments and his work ethic beyond reproach. More telling than his business persona is who he is as a person. This can best be summed up by describing the events following our picking up the truck after the work was done. My son headed home and called about 15 minutes after leaving telling me that his girlfriend following behind saw sparks from under the truck. He started to pull over and as he did the front driver wheel bearing let go and the wheel almost came off. When I heard about this I was still standing with Lance. As soon as he found out what happened and though he had no reason to help, Lance immediately said let’s go and jumped into his truck. Before we left he called a friend with a flatbed and had him come along to help recover the truck. I want to be clear here that the welcoming had absolutely nothing to do with the repairs that had been done by Arc Tech. He went out with us to where my son‘s truck was, helped us, evaluate it, and stayed until we found a tow truck to get it home. As he had to back at it at 4 am, he wished us luck and finally headed back. This had nothing to do with his work, but solely reflects what kind of person he is. While I 100% can recommend his work, it isn’t the excellent work he does that should be the standout in this review - it is the character of the man behind the company. While it’s hard sometimes to find quality workmanship, it is much rarer to find quality businessmen. It’s even rarer to find good people. In Arc Tech you will find all three. I rarely can, without any reservation, recommend a company - but in this case I can unhesitatingly recommend the work, the company and the man. You can’t do any better.

Arc tech got me out of a bind. Was having a hard time finding a mobile welder in the area that did automotive work. They were super responsive, flexible, and had time the next day to come out, and get the job done right! 10/10 would recommend if you need mobile welding work done in the area.

The hanger bracket for the axle on our RV broke off, taking with it the section of I beam it was attached to. Lance came on short notice (we were on vacation) and did an excellent job of repairing it. It's much stronger now than original. I couldn't be more pleased with his work or professionalism.

5 stars is not enough! I was fortunate to find Arc Tech after months of searching for a closer mobile welder who would return my calls or follow through with scheduling. Within 3 days of describing my project, Lance was able to complete my project even though it involved multiple obstacles. He did so with professional and personal communication, reasonable pricing, and a friendly and optimistic attitude through my many questions. He explained all his recommendations and actions and I would not hesitate to go to him for all welding work I have in the future. I cannot say enough good things about my experience with Lance and Arc Tech!!

Called up Arc Tech to see if they could build me a back porch for my camper to sit on. The design I had in my mind would be removable when I took my camper off and it would give me an added 18 inches of room behind my short bed ram 1500 truck.

We bought a container and needed a window and man door put in. Lance was incredibly professional and presented an estimate that was acceptable and easy for us to say yes to. He kept us informed as the project went along as to where he was at. He worked with the install company very well and coordinated with them so I had no worries. It was incredible stress free and we love the end results.

Needed some repair welding done on my 5th wheel rv. I called Arch Tech Enterprises. Lance came out yo my house, looked at the project, and gave me a quote. Had it approved by manufacturer, let Lance know it was a go, he gave me a date, and he just finished the job. Nice work, and he communicated verry well with me on time, prep, and completion. Great job done! Thanks Lance Dennison for the great work !

I contacted Lance via email, sending him some pictures of my broken brush hog. Lance replied back a few hours later (late evening) saying he would call me in the morning. He called the next morning and we set up a date for him to come over. Lance gave me a reminder text a few days before, then called the day of asking if it was okay to come over about a half hour earlier than planned. Lance arrived with Justin (apprentice) in tow, Lance looked things over, taught Justin a few tricks of the trade, and they started the repair. After burning off the old rusted bolts and removing them, they started the repair. As the repair was about done Lance looked over the brush hog and found more cracks that were starting. Lance highly suggested fixing those also, since the hub spins at a high speed and is dangerous if it breaks. Lance and Justin fixed those up real quick, and only slightly more money. Lance had great communication, before and while here, highly recommended. I sent repair pictures to my father who lives out of state, as a former fabricator, he said Lance did the job the right and a very good job.

Ark tech is a great outfit, Lance will set you up. We had a dif lock go out on our Garden tractor and it drove a gear through the case but didn't damage any of the main working areas of the dif. Lance was able to show up and patch it hasn't had a single problem since. The aluminum welds look great and are holding strong for over a year now.

11 out of 5 stars 🌟 I honestly can not say enough good things about this guy. Lance has a professional attitude, is extremely knowledgeable in his craft, creative and ingenuitive, takes the time to communicate in detail what he is doing so that you are not left in the dark, and possess a level of integrity not often found these days. He is honest, trustworthy and fair. In all the years that I have known him I have never heard of him doing anyone wrong. If you have a job that needs done, do not hesitate to hire this man. You will not only not be disappointed, but rather delighted with the outcome of getting your needs met. In my humble opinion, he goes above and beyond for his clients. Keep up the good work buddy! 💪🏼💪🏼💪🏼

I had a medium sized welding job that I needed done and Lance came out and did an AMAZING job! I was a bit nervous hiring a welder since I have no experience with it and no nothing about it. Lance explained everything to me and was quick and efficient! I'm lazy, so I hardly ever leave Google reviews. I only do it when I have a really excellent experience with a business and I had that with Arc Tech!
