Brought this shop a fairly simple job to weld two m/c parts. I told Danny there was no big rush as…read moreit was Nov/Dec. I was told he would get to it next week. I didn't hear from him for a month and assumed he misplace my tel#. I was told he would be doing Aluminum the next week. This went on for nearly four months! I was very patient and didn't pester him ( I called probably every 4 weeks or so) Finally after all my patience I was told he didn't want to do the job and I should pick up my parts, left outside his shop door. Unreal!! I went to his shop to retrieve my parts only to find one of them missing! I was told all the parts i brought him, 3, were in the box. ( I brought two parts to be welded together, one half was missing! He then found the missing part in his shop, and I returned a second time to retrieve. Bottom Line: RUN!, don't walk away from this guy. Nearly 4 months waiting patiently and he tells me to pick up my parts. Who does this? Guy's a joke, he can't be trusted. I'd give him NO stars if possible.

Very knowledgeable, quality work, reasonable prices. would definitely recommend this business.read more

Disappointing experience overall…read more Verbal bid was given of 10k to 11k for the job over a FaceTime phone call as the project was explained. I politely asked if he could please try to keep it near the 10k. Written bid came in over 11k. (11,700$) Discussed that the bracing for the large metal stairs should probably be secured by something more than anchoring into stucco. To add proper supports the bid goes up again to over 12k. (12,800$) I would have liked a more professional experience where pricing didn't keep changing and for Christian to take the lead on making the stairs braced correctly and safely from jump. He kept saying this is simple we don't need to discuss the job so much. Also I had originally texted him to FaceTime me when he was onsite. He was on time but didn't respond to my texts. Had to wait 20 minutes for a response. He already left the job. Had to drive back to the job to be able to Facetime me. It is a large job that involves a lot of safety concerns. Was really looking for more professionalism to have the job bid correctly from the beginning and the scope of the job to be discussed throughly on time to get it created safely.
