An American Contractor Shares His Story with Xiashi

In the U.S. contracting business, the selection of every single building material is critical. Choosing the wrong products can lead to costly rework, dissatisfied clients, and financial losses; conversely, selecting the right products can significantly boost efficiency, ensure the long-term durability of a structure, and help you build a more solid reputation within the industry.

Recently, we had the privilege of interviewing Mike—a general contractor based in Ohio. For the past three years, he has exclusively utilized our Jinbo® breathable waterproofing membranes and window flashing tapes. Below, he shares the details of our collaboration.

First Impressions: Quality You Can See

Mike first discovered us through an online search. At the time, he was seeking a reliable waterproofing solution for a wood-framed residential project. He had previously experimented with products from various other brands but repeatedly encountered frustrating issues: inconsistent material thickness, insufficient adhesion, and flashing tapes that began to peel off after just a few months.

"The very first sample roll I received from 'Xiashi' felt different right away," Mike remarked. "You can tell at a glance whether a product is truly well-made. This waterproofing membrane features a robust three-layer structure; the tape adheres firmly the moment it is applied; and all technical specifications align perfectly with the details listed on the product data sheet."

It was precisely this consistent quality—from the initial samples to large-scale bulk orders—that secured the opportunity for our ongoing partnership.

Real-World Performance on the Jobsite

Over the past three years, Mike has incorporated our products into more than 40 projects, ranging from new residential builds to commercial renovations, and even a small-scale Passive House. He has put our materials to the ultimate test under the most demanding real-world conditions: enduring scorching summers, biting cold winters, and every climate condition in between—yet our products have consistently performed with excellence. “Last January, our construction crew installed this breathable waterproofing membrane on a roof. Although temperatures had dropped below freezing, the material remained remarkably flexible and bonded perfectly to the substrate—without any cracking or edge curling. That kind of exceptional performance isn't something just any brand can deliver.”

He also specifically highlighted our window flashing tape as a standout product. “Water always finds a way in around windows and doorframes—unless you’ve achieved a watertight seal. Thanks to this tape, I’ve been spared countless hours of rework and repairs—more than I could ever count.”

Why He Sticks With Us: Trust, Consistency, and Support

When we asked Mike why he chooses us over cheaper alternatives or more famous, big-name brands, his answer was simple and direct: Trust. “Every time I place an order, I know exactly what I’m going to receive. Consistent thickness, uniform adhesion, accurate roll lengths, solid quality—there are never any surprises. Plus, whenever I have a question, their team is always right there to provide an immediate response.”

They also place great value on our customization services. “Some projects require materials of specific widths, or need custom packaging for a client. In this regard, they are always incredibly flexible—making the collaboration process smooth and effortless.”

Delivering on Promises Through Certified Excellence

Mike admits that he tends to be skeptical of marketing hype. That is precisely why, from the very beginning, he placed such high stock in our various certifications—including ISO 9001:2015, CE, and SGS.

“Many suppliers claim their products are of ‘superior quality,’ yet few can actually produce independent third-party test reports. ‘Xiashi,’ however, proactively provided me with detailed testing data before I had even placed my first order. That level of transparency convinced me that they are a company that takes its work seriously.”

Looking Ahead: More Projects, An Unchanging Partner

As Mike’s business continues to expand, his order volume is growing right along with it. Currently, he is actively evaluating our reflective films and anti-condensation felts, with plans to incorporate them into a series of energy-efficient building projects set to launch in the near future.

"I simply cannot find any reason to switch suppliers," he stated. "They have earned my long-term trust through tangible, real-world performance—consistently delivering the same high standards, regardless of the specific project or the changing seasons."
