I just wanted to reach out to and your team and thank you guys. You guys are always there to assist and you do a great job servicing us. My team and I appreciate all of the work all of you and your team does for us. One of your technicians while doing other work at our Forest Glen garage took the initiative to address a major issue with some of our units having a bad diesel mix. It’s good to know that we have contractors that care and it’s important to give credit where credit is due.

We have used HiGH PSI LTD for all our power washer repair needs for over 5 years and have never had one issue. They have an excellent courteous receptionist and their techs are always timely and friendly. Their technicians have always solved our issues that day and have recommendations on how to prevent failures.

Thank you HiGH PSI Team!
