BASF Lethbridge
The BASF Canada – Lethbridge Canola Processing Facility has worked closely with Top Notch Mechanical Ltd. for the past 15 years. All our plumbing and mechanical needs over these years have been completed by TNM. We have relied on TNM to scope some fairly large projects and these have been executed flawlessly.The entire Team at TNM is very flexible and experienced for any kind of mechanical job.

We have referred TNM to many clients, friends and colleagues over the years and will continue to do so. TNM and their entire team always make us feel like we are their top priority and are always available when needed, whether it be an emergency, a service issue or required maintenance. Josh is extremely knowledgeable and is always helpful, friendly and shows up with a smile ready to take on whatever we need.

The team is knowledgeable and professional. They are keen to make recommendations and explain each of them in detail…repeatedly if required! They routinely follow up to confirm the work completed is functioning as it should and are genuinely helpful.. They worked tirelessly on assessing the issues and have made countless trips back and forth to determine our best path forward. They have been cognizant of cost and future requirements and have provided options, noting the pros and cons of each. I would completely recommend Top Notch to my colleagues.

Hunter Heggie
Heggie Developments Ltd.
These guys are gold! Seriously. They were clean, efficient, honest, and complete gentlemen. Josh, Tony and Duane were able to figure out some very complex problems I had in my system. And on top of all that, their pricing was incredibly fair! I have always received professional service from Top Notch. They are truly "Top Notch”. I recommend them wholeheartedly to anyone who wants to deal with the best.
