What is this?

What is this?

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

Comments

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

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.

Everything was done promptly, and Dmitri was very knowledgeable and gave us all the necessary information to make the necessary improvements. It was in conjunction with Public Service with an energy efficiency update of our house that was forty years old, so everything was brought up to code and then some.
