"Was surprised to get a response as quickly as I did. Even more surprised that he was able to complete the job the next day. Plumbers in this area are few and far between. We have a lot of iron in our water so this system has a third tank that addresses this issue instead of a small filter that we had to replace quite frequently."

"I don't like their complaints. The sewer water it's so full of tree roots. I always say that it was too foul. I was anticipating. I would use them again."

"Mr. Paul is a extremely knowledgeable and compassionate about his business. He detected the problem of mold in my basement immediately. He was able to locate the source of the water intrusion. He was up front about the problem and what is would cost to fix it. He gave us multiple options on the prices. I am grateful for his honesty. I will definitely use him and refer him to my friends. Thank you Mr. Paul.

"It went excellent. We have used Spenglers in the past for a complete Water Heater replacement, their office staff are spot on, their field techs are professional, personable and knowledgeable. They arrived on time, I was notified by the office when they were on the way, they made their scheduled arrival, and the entire job took less than 4 hours. The quality of materials is outstanding, the lines were all soldered in without any leaks, and the technician even took the time to show me how the new faucet could be tightened if leaks appear later on. This job is now two months complete and I have no leaks, and I can (finally) wash the cars and water the front flower beds without hauling hose or buckets. Awesome job for the Spengler's team!
