Your Trusted Partner for Commercial Water Management

At BAM Sheet Metal Co., we specialize in the fabrication and installation of high-performance rain gutter systems designed specifically for the rigorous demands of commercial and multifamily properties. For general contractors, a reliable water management system is not just an accessory; it is a critical component of the building envelope that safeguards the structure’s integrity and longevity. We understand that failure is not an option. That’s why our entire process, from initial drawings to final installation, is built around delivering a precisely engineered gutter system that performs flawlessly under the heaviest conditions.
Our key advantage lies in our in-house fabrication capabilities and our team of experienced journeymen. This powerful combination allows us to maintain complete control over quality and scheduling. While other subcontractors are delayed by supply chain issues, we are fabricating your custom system to exact specifications. This focus on speed and dependability ensures we integrate seamlessly with your project timeline, making us the reliable partner you need to keep your project on track and your building watertight.

Final Walk-Through & Quality Assurance

On the Azure Creek project, we had three major rain delays. BAM’s gutter system was the only thing that didn’t leak. They were in and out two weeks ahead of schedule, saving us a fortune in potential water damage repairs. They’re our first call now.

I'm very happy with the new rain gutter and downspout re-routing work provided by BAM. Irvin and Gilbert came out after I received an estimate from Brian. They did a very nice job and paid close attention to detail to make sure that rain gutters blended in as well as possible and would work properly. I appreciate that Irvin pointed out a couple of things that I hadn't thought of that helped with the look and functionality. They made sure I was happy with the work before they left and said they would come back if I had any problems. Good guys!

BAM Sheet metal has earned those 5 Starts in my book. Byran the owner called me back in the middle of a recent rain storm within 2 hours, that is in itself amazing. But understanding my situation (Rehab of my house during exceptional weather) he was able to get to our issue in a timely manner. Then he sends out the installers. Irvin, and Gilbert.....what a pleasure to deal with two men that knew what they are doing, and do it well. As an amateur I thought I knew what I was doing and what I wanted, but.... They were able to explain how things works in a very logical and simple manner.......I bowed to their expertise, because they were right. As to the pricing, not the lowest, not the highest, but I got way more than I expected. Communications, fast, on point, no waste of my time. Enough said? You need to contact me? Please do. PS CiCi in the front office, not paid enough to have to deal with likes of me...Thanks CiCi

I would like to share about my experience with BAM Sheet Metal. I am currently working on an old building renovation. We were getting ready to install windows when we discovered the framing on all 8 commercial windows had water damage. Our window contractor said "don't worry I have a guy who can take care of this"... Well, that's when I met Bryan.... Bryan came in right away to assess the damage. He was upfront, explained what caused the damage and what had to be done to repair it for years to come. I was given a very reasonable price and Bryan was able to get his crew working on this the very next day. They came in with guns blazing.... all windows were layered and waterproofed, his crew worked non stop until the work was completed. Even when they were at a pause due to another contractor delay, he offered to take some wood we had on site and finish that contractors work so his crew could proceed. I was extremely impressed with the quality of their work, the timeline and price. I am giving BAM Sheet Metal a 5 star (because Google doesn't give an option for 10 stars). Thank you Bryan.... you, by far have been one of the most honest and quality contractors I've worked with!
