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.

Joe Johnson was totally professional. SolarGem did a great job installing the system, and the system works fantastically. All of the employees did a great job.

I was impressed with Joe and his entire staff at SolarGem. They were responsive and professional throughout the entire process while installing solar panels on my property. All went as planned and I am very satisfied with the decision to "Go Green" as well as the long-term financial benifits.

We have since...
