J&M Keystone, Inc. was established in San Diego almost 40 years ago. With over 100 years of combined experience in emergency water damage restoration, reconstruction, and other specialty cleaning, J&M is a full service restoration contractor.

GuildQuality customer satisfaction surveys enable homeowners to rate their contractor on a scale of zero to four (with zero being the worst and four being the best) in all sorts of categories. Our members can publish a summary of those answers here on their profile page, displaying a bar for as many or as few questions as they like. The score for each category indicates the percentage of survey respondents who answered a three or four to that particular question.Learn more about the feedback published on this page.

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.Learn more about reviews and comments.
