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 Klam Construction

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

We have surveyed customers on behalf of Klam Construction in Portland, OR; Beaverton, OR; Hillsboro, OR; Gresham, OR; Lake Oswego, OR; Oregon City, OR; Sherwood, OR; Tualatin, OR; Boring, OR; Gladstone, OR; and 20 other cities in Oregon and Washington.

In this report, Klam Construction has published a summary of the customer feedback they've received since they joined GuildQuality in November 2016. In that time, 237 out of 325 customers (73%) responded to a GuildQuality satisfaction survey, with the most recent response in January 2020.

Klam Construction surveys all of their customers with the following exceptions:

  • Clients are not residential homeowners

Customers receive a brief survey shortly after the completion of work, and their feedback appears in the summary on this page.

If you are a Klam Construction customer, if your project doesn't match the above exceptions, and if Klam Construction completed work for you after November of 2016 but you haven't yet received a survey, please let us know.
