Website Fix & Repair FAQ & Customer Testimonials
TRUSTED PARTNER FOR EMERGENCY FIXES & ONGOING MAINTENANCE
Do you need admin access to my website?
Yes, to diagnose and fix the issue, we typically need Administrator access to WordPress (or your CMS) and often FTP/SFTP access. We recommend creating a temporary account for us, which you can delete once the job is done.
Will my website go down while you fix it?
or most frontend fixes, your site stays live. For complex database or PHP errors, we work on a “Staging” copy of your site first. We test the fix safely in a separate environment before applying it to your live website, ensuring zero disruption for your visitors.
Do you work on sites you didn't build?
Absolutely. A large portion of our work involves taking over and fixing sites built by other agencies or freelancers. We are experts at reading and debugging code written by others.
What if the issue comes back?
We offer a 30-day warranty on all our bug fixes. If the exact same issue reoccurs within 30 days of our repair, we will fix it again at no additional cost. We fix the root cause, not just the symptom.

They helped us create a beautiful and functional website that exceeded our expectations. What impressed us most was their willingness to make numerous small changes to ensure we were completely satisfied with the final result. I really appreciate their excellent work and hospitality. I will definitely return to Sierra Group for future website services. Highly recommended!

- I've had the pleasure to work with Sierra IT on a number of projects, from building basic websites to full on web shops. As a one stop shop, they do all aspects from website design, coding, and SEO. Even helped us set up payment processing. For every project they've worked efficiently and fast paced, and gone above and beyond for every aspect of website design. If anything they are too fast and the customers are the ones that feel slow since we have to take time to finally decide what it is we want! If anyone is on the fence, get off it and work with these guys. I'd give 10 stars if I could.
