What is this?

What is this?

We display two types of written homeowner feedback on GuildQuality member profile pages: Comments and Reviews.


In response to our customer satisfaction surveys, homeowners share lots of comments about construction quality, communication, or any other question asked in the survey. Guildmembers can selectively publish these comments here on their profile page.


Reviews are different than comments. These are star ratings that homeowners ask us to publish, and they come with a written description of the type of experience they had working with their contractor. We publish all of the reviews we receive: positive and negative alike.

More about Mifflin Construction

As a GuildQuality Guildmember, Mifflin Construction relies on our customer surveying to help them deliver an exceptional customer experience.

We have surveyed customers on behalf of Mifflin Construction in Pittsburgh, PA; South Park, PA; Irwin, PA; and Belle Vernon, PA.

In this report, Mifflin Construction has published a summary of the customer feedback they've received since they joined GuildQuality in May 2017. In that time, 5 out of 6 customers (83%) responded to a GuildQuality satisfaction survey, with the most recent response in April 2017.

Mifflin Construction surveys all of their customers shortly after the completion of work, and their feedback appears in the summary on this page.

If you are a Mifflin Construction customer, and if Mifflin Construction completed work for you after May of 2017 but you haven't yet received a survey, please let us know.
