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.
