History

Established in 2008.

Formerly known as JC Roxx Computer Services in San Diego, founder David Steckling has recently moved to the Redlands area to join forces with his business partner in bringing top quality pc restoration services to the Inland Empire.

David honed his skills as a virus busting, performance fine tuning specialist while first fixing friend’s and family’s poorly performing PCs. Through thousands of hours of googling (yes, that’s a verb!), and going back to college to take an intense 7 month Computer Systems Technology course, he has learned how and now become a top notch specialist in saving sick computers from death without losing any files.

Cornerstone’s restoration service is very comprehensive, and addresses all possible performance hindering issues to ensure top notch speed. Several years ago, JC Roxx started using a remote access program to do follow up warranty repairs. The customer would simply call to report an issue, and they would log on remotely to fix it! No home visit needed!

Cornerstone reloaded my Surface Pro.
A very professional job.
Excellent service.
I checked Unilocal and found this vendor.
I was not sure if my issue and David was extremely helpful.
He contacted me throughout the repair to make sure I was satisfied.
Estimate was accurate and he delivered on time.
It is great to find a local repair service that has quality.
I highly recommend the service and will use them again.

I can’t say enough good things about Cornerstone. After taking my Toshiba to a large company for repairs, and to my great disappointment noticing that the same issues returned after just one week, I decided to call David and give it one last shot; that was a great decision. David is the right person to contact for complete repair work and restoration. In my case, I didn’t want to part with my laptop; it’s a solid piece of machinery. But getting rid of it became an option due to my growing frustration. David listened to all my concerns with patience, answered all my questions, thoroughly examined and repaired the computer, added memory, and made it more secure. He works with diligence and integrity, is extremely knowledgable, and will fix your computer as if it’s his own. Thanks for giving me a good experience.

David is one the most professional and courteous IT Techs that i have ever worked with. I had 5 computers, sever and print copy machine in need of complete over hall. For those of you like me that don’t know computers nor the language of computers, David takes the time to break it down, like speaking to a four year old. This was a big perk for me. What i also like is his dedication to the Job, once he begins the task he does not like to stop until he reached the desired goal. In conclusion, David represents himself and Cornerstone Computer Restoration with the Utmost Integrity as advertised in the name of his company. i would highly recommend him to anyone.

Dave with Cornerstone has saved my day more than once! He is always available and gets the job done. Just this week he fixes my laptop that had a virus or worm or something and had it back within 48 hours. While he was here for the laptop I told him our PC had a message saying it was dumping all hard drive so I shut it off. He fixed that in a matter of minutes! Dave with Cornerstone is our family’s GO TO COMPUTER GUY!

My Dell Vostro 200 desktop computer, recently upgraded to Windows 8.1, started making a horrendous noise. When shut down, I had difficulty getting the power button to turn the computer back on. I’m not a computer expert, but I’m willing to look under the hood, and I had previously installed a new video card in this computer. Upon removing the cover, I could see the component whose fan seemed to be making the noise, but I didn’t recognize the component. Being fairly new to Yucaipa, I looked for computer repair shops online and decided to call Cornerstone in Redlands. David had me describe the problem over the phone and asked me if the malfunctioning component was the one the external power cord was plugged into. Uh, yes, as a matter of fact, it was. Thus David was able to tell me I had a faulty power supply. (This is where I felt stupid for not figuring that out myself.)
I expressed some interest in trying to replace the power supply on my own, and far from being offended by that prospect, David suggested I could buy a new one on eBay, which I proceeded to do. I thought I would try to install it myself, but if that seemed too difficult, David was willing to do it for a reasonable fee. He suggested that before removing the old power supply, I carefully note where the various cords from the power supply were running and take a few pictures with my cell phone. Sure enough, the new power supply came with no instructions, so I would have been lost without following that advice. I was able to do the install myself, and my computer is now purring like a kitten. For David’s help and advice he made exactly $ 0.00, but he has definitely earned my goodwill and future business.

Dave was very helpful to my mom (over 80) and her friend. He was kind, on time and was very friendly. His visit came at a ‘bad time’ for my mom, but he was gentle and considerate of her feelings. He was good to pray for her, with her permission, not all computer guys are that ‘caring’. Thanks for the help to my mom.

I have an HP laptop computer that I could not reformat the hard drive and Dave told me how I could do it myself and gave me paper instructions. I am impressed. Thanks, Randy Harris

I had been having unexplained troubles with my computer and needed it fixed quickly. Brought my computer to Dave on Friday afternoon and he was done with it by Saturday morning! I haven’t had any problems with it so far and he was also very friendly and accommodating. Also the 6 months warranty after having it fixed is very reassuring. If you’re having computer trouble I would highly recommend this place.

Dave has been keeping my office computers up and running for several years now. He is always accessible when I have an emergency and is patient enough to walk nervous me through the problem or will take over my PC to fix it. He always leaves me with a tip that makes my life easier. I wouldn’t think of calling anyone else!

I had 2 «sick» computers, so I called and had them come out. He was awesome! He actually did a quick analysis (free) and let me know what was wrong and how to fix it. I am using Cornerstone for our business needs from now on. Pricing is very affordable and service is great. Highly recommend!
