Opinion Surveys

We surveyed area Checkbook and Consumer Reports subscribers for their feedback on services they have used. We also surveyed a random sampling of other area consumers. On our surveys, we ask consumers to rate their experiences with companies they had most recently used on several aspects of service. Our ratings tables show the percent of each company’s surveyed customers who provided a rating of “superior” (as opposed to “inferior” or “adequate”) for questions on our survey. We sometimes also report the percent of surveyed customers who rated each company “adequate” or “superior” (as opposed to “inferior”) for the “overall quality” question on our survey.

We have included on our ratings tables all of the companies for which we received at least 10 ratings on our customer surveys. If a company is not listed on our ratings tables, it simply means we did not receive at least 10 ratings for it.

Since many companies were rated by rather small numbers of raters, small differences between two firms in the percentage of raters who gave a particular rating (say, “superior”) should be ignored. The table below gives a rough guide to minimum differences you should look for in deciding on one company over another.

When using these survey data, remember that the questions are to some degree subjective and that the differences among companies might be explained by differences in the personalities, backgrounds, critical standards, and other characteristics of the raters or by biases these raters might have.

Complaints

For many of the services we evaluate, our ratings tables show the number of complaints filed against each company with the Consumer Protection Division of the Washington Office of the Attorney General for a two-year period.

When using the complaint information, keep in mind that complaints are not always justified; sometimes the customer is unreasonable. Another problem is that we didn’t have a measure of business volume and therefore couldn’t control for differences in companies’ exposure to complaints.

We always recommend that you look for substantial differences in complaint counts. We also advise giving little weight to complaint counts if the total count against a company is less than three or four.

Price Comparison Scores

To compute our price comparison scores, we calculated an average price for each job or item for all the companies that quoted on that job or item. Next we compared each company’s price to the average. One company might come in at 120 percent of the multi-company average for a particular job, and another company might come in at 90 percent. We took each company’s percentage score on each job or item, standardized it, and assigned a weight to each job or item, based on our judgment. We then averaged the standardized, weighted percentage scores to find how the company compared to other companies overall. Finally, we multiplied this overall percentage score by a flat dollar amount, say, $100.

The price comparison score, then, is intended to indicate the relative prices we found for the companies, adjusted to the base of this flat dollar amount. These scores are imperfect for various reasons: for instance, the jobs or items checked may not be representative; the weighting of various jobs or items in the scores may not accurately reflect typical expenditure patterns; and the number of jobs or items is small.

Timeliness of the Data

All of the data must be interpreted in view of timeliness.

Our customer survey data are from surveys conducted from January 2011 to November 2024. Survey respondents were asked to report on experiences in the preceding year. Our data on complaints for the Consumer Protection Division of the Illinois Office of the Attorney General are for a two-year period between January 1, 2020 and December 31, 2021. Our price data were collected from November 2021 to March 2022. The data from our surveys of companies to ask about facts such as types of pets boarded were collected from March to April 2022.

Our tables include companies for which we collected 10 or more ratings on our customer survey during the customer survey period mentioned above, but we do not report data for periods prior to companies’ changes of name and ownership. As a result, some large companies are not listed at all. If only name or ownership changed, we do report the data. Changes subsequent to the dates listed above may not be taken into account.

Top Ratings

We give checkmarks to companies that score highest on a scoring system that we devise for each service field. Our scoring systems weight the various data in our tables and text based on our subjective judgment of their importance. Since the scores are based entirely on information presented, you can apply your own subjective judgments, and decide whether you prefer companies we have not given checkmarks. Where we do not have important data on a company, we cannot give our checkmark.

A rough guide for deciding whether the difference between two percentages is important If one firm had this number of ratings: And a second had this number of ratings: Do not give much importance to the difference between percentages unless the difference is at least this many percentage points:
