An IT firm with no Google reviews scores zero on rating, review volume and recency; other factors we cannot measure are left out. Only IT firms with a confirmed service and 3 or more reviews, or a claimed profile, are ranked.
Do computer repair shops outside Castle Rock count in this ranking?
Yes, if they are within 20 mi of the Castle Rock city center, our service radius for computer repair shops. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.
Can computer repair shops pay to rank higher on ITFirmsRanked?
No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.
What does a computer repair shop do?
Computer repair shops fix desktops, laptops and printers in store or on site: hardware repairs, upgrades, virus removal and setup. Many serve small offices as well as households.

By IFR Score: Google rating and review volume, recent reviews, opening hours, how clearly the firm does computer repair, distance, a claimed profile, our badge and verified client reviews. Sponsored placements never change the order.
Should a business use a computer repair shop or an IT provider?
A repair shop suits one-off fixes on a few computers. Once you rely on shared files, email, backups and security across several staff, an IT provider with a support agreement usually works out better.
Should we back up before a repair?
Yes, if the computer still starts. Repairs can involve replacing drives or reinstalling the system. Ask the shop whether it backs up data first and what it charges.
