Pipe Spy Inc. uses state-of-the-art equipment to perform trenchless sewer replacements and camera inspections for residential and commercial clients in Alameda and Contra Costa Counties. The company also provides various sewer diagnostic and repair services, and it utilizes its expertise in all areas of sewer compliance to help resolve sewer boundary issues with neighbors and city agencies.

Owners Paul Cooper and Heiko Dzierzon established Pipe Spy Inc. after noticing a growing  need for sewer lateral repair and replacement for Bay Area homeowners. “We used to install sewers the old-fashioned way—by digging big trenches across property lines—but after only two years of operations, we saw technological advancements like pipe bursting and knew the industry had to change,” explains Mr. Cooper. “We worked  with local officials to bring those benefits to Bay Area homeowners. Trenchless technology lowers the cost of sewer replacement by 50 percent or more, and it has become the new standard for the way sewers are replaced.”

Pipe Spy Inc. emphasizes clear communication with its clients throughout every step of their sewer projects, which Mr. Dzierzon says is important for establishing their needs and effectively solving their problems. “When we take the time to solve a customer’s problem, they feel like they’ve received an exceptional value, which is a key component of the relationship. Even if we don’t have a solution in-house, we’ll point them in the right direction.”

Company Philosophy

“We strive for competence in action, from how we engage with our customers to how we perform our work. We work together for our clients, our employees and the company, so our goal is 100 percent customer satisfaction in every situation.”
