Customer Testimonials

Manager of Civic Facilities

I have found Darren and his company to have been consistent over the years in their high level of customer service and industry knowledge. Our municipality has seen a reduction in graffiti expenses due to preventative vandalism products Darren has recommended and provided.

I had Darren replace my roof on my 31' travel trailer I was impressed with the price & warranty . My trailer needed a bit of extra attention .Darren went that extra mile to make sure I wouldn't have any leaks & backed it up with a really good warranty .

Larry Coombe


We had our fifth wheel roof resurfaced after visiting your booth at the Arbutus RV show, and am pleased to say how happy we are with the product. We have just returned from our second time out with no sign of any problem. The two things that caught our attention were the warranty provided. Ten years, and the cost was well less than half of traditional methods. Feel free to have prospective clients contact us. Larry and Colleen Coombe

Construction, Rental Revenue & Marketing

After our business premise's were hit on the weekend with spraypaint, Darren and his crew from SEI were incredibly quick in responding to my call for help. The job was accomplished professionally, with amazing results. The technology that SEI employs is remarkable in it's ability to remove unwanted graffiti, and at the same time leaving the original surface intact. I commend and recommend Darren for anybody needing his services. Great value and great service!

SEI Chemical have been providing graffiti removal service to the Downtown Nanaimo Business Improvement Area for five years. Darren and Tasha have always provided exemplary service in a professional manner. We have benefited greatly from the application of preventative treatments to public art pieces, poster poles and more. The fast and efficient removal of graffiti has lead to a significant reduction of tagging in our BIA over the past couple of years.

I have had the pleasure of working with Darren on several occasions while he was a Mentor to our MBA students. His constant dedication to taking precious time out of his work day to meet our students at our networking events, or attend their presentations to provide his expert advice, is truly invaluable. Darren's thoughtful, intelligent and encouraging real-world advice from his perspective as a successful businessman helped our students to understand the demands of the industry. We are truly fortunate to have Darren as a dedicated supporter of our future business leaders.
