what our clients have to say
We have been working with Niagara Industrial Mechanical on smaller jobs before, but this bigger project really shows their value now as we see them delivering work every day. They are handling a long-term relining and structural reinforcement job for us now, and from the start, they’ve been straight-up and dependable. When something didn’t look right, their crew stopped, called, and made sure we were all on the same page—no guessing, no ego. They don’t skip steps or rush to move on. The work’s been solid, consistent, and they take real pride in what they do. Costs are fair, they help keep things moving by sourcing materials when needed, and they stay flexible when plans change. Communication’s been easy, respectful, and professional all the way through. Overall, it’s been a smooth experience, and we’re already lining them up for more work as they are earning our trust.
NIMS does exceptional work. They follow all of the plant and safety rules and always clean up when they complete the job. NIMS is an excellent company to have as a vendor. Highly recommended.
More than once we had a last minute repair and NIMS was there to help us out. Their guys were on time and did a great job!
Niagara Industrial Mechanical was able to complete a much needed production part with a very short lead time and delivery date. This being the first order that we purchased from NIMS has shown us that they are committed to producing and delivering whatever is needed for their customers with the highest quality and production standards there is. Thank you Niagara Mechanical and we look forward to doing business with you in the future.
NIMS has been one of our contractors for many years. Quality work, timely customer service and off shift availability for our 24/7 operation has made them a great partner for us.
I can always count on the team at NIMS to perform safe, quality work, while meeting our sometimes demanding scheduling requirements.
