We have all the feddbacks of people who purchase the products of Knauf Fiberglass (Contractor) in the state of California.
At the moment the business has a score of 4.0 stars over 5 and this score has been calculated on 45 reviews.
As you can see its rating is positive, and it's based on a very large number of scores, so we may be pretty sure that the assessment is very reliable. If there are many people who bothered to give their feddback when they've done well with the service, is that it works.
As you know, we don't usually stop to give reviews when they are good and we usually do it only if we have had a problem or issue...
