Diablo Iron is "top-notch" all the way around. They were pleasant to deal with, did up front visits to our site, and installed a great product in the form of two iron gates. They provide excellent value along with their customer Service. We would highly recommend them.

Critical: Professionalism
If you are a Privately owned HOA and looking for a reputable professional vendor to do iron work on your property DO NOT waste your time contacting Diablo Iron Inc. For some unexplainable rationale or short sighted logic they are simply not interested in engaging. Granted that is their business prerogative.

Diablo did a perfect job installing my new Handrails. The work was measured and done in the timely fashion with care taken to match other handrails on the property. I highly recommend them.

Diablo Iron just installed some elaborate outdoor railings for us, and they look great. Very easy dealing with their estimator Sam Hewett, followed by careful measurements and clean installation. They originally quoted painted, but I suggest powder coated for longer reliability. Not cheap but definitely first class.

I found Diablo Iron after calling around as I needed a courtyard gate. They were the most reactive to my calls which was a good start. I had requirements which Karen asked for and she came up with a perfect design to go with the rest of my door and windows. After some time, they were finally able to get to my project and it went like a breeze. The gate was gorgeous and I love it! Very professional company and I would recommend them to anyone.

Diablo iron designed and installed a gate for my front patio. Karen came by first to show options and measure in order to design the gate and quote the estimate. Then they came out to get more detailed measurement. Installation followed without a hitch. Final invoice matched the estimate. Very pleased with my new gate.

With toddler grandkids moving to the Bay Area on short notice, we called Diablo Iron in desperate need of an attractive iron fence installed around our pool, and installed quickly. Karen and John are the owners, and Karen couldn't have been more understanding, accommodating, and helpful. She moved her schedule around for us and in less than 10 days, husband John and son Sam were at our house to install everything. But that was just the beginning of our great experience. They are a family business with family values. When John and Sam saw the drop off between our concrete patio and dirt

We hired Diablo Iron to put in our new automatic driveway gates and some matching iron fencing and pedestrian gates. The craftsmanship and service were excellent! The design of the gates turned out so nice. There are so many decisions to be made for automatic gates. It seemed overwhelming at first but with their help we got through the process and everything turned out great. John was able to coordinate his work with the other subs that were working on our new landscaping so everything went smoothly. We couldn't be happier and get many compliments from our neighbors!

I had a rocky time getting a quote from Diablo Iron for a handrail. I had a railing with some custom mounting needs they seemed a really good match for. In the end I finally got through, Karen & John visited, and I have a competitive bid in hand.
