We couldn’t be happier with the work Ken Adams Mechanical did for us..They installed four electrical outlets at various places in our home. Prior to the installation, Ken came to our house, discussed our needs, explained how he would have his team perform the work, and answered all our questions.

Ken arrived with two of his employees on the scheduled workday, and Ken explained the work to his team. These two employees
were polite and courteous,
worked very hard all day, performed the work flawlessly, and cleaned up after themselves. The result was a perfectly executed project, which fully meets our needs, at what we believe was a very fair price.

We highly recommend Ken Adams Mechanical, and will be contacting them for future work. We now feel like we have a friend in the business.
