"The technician, Steve, called me 25 minutes prior to his arrival. He was extremely knowledgeable about my gas fireplace. He vacuumed all areas. He informed me of the condition of the components. I was prepared to ask him a handful of questions that he was able to answer. My fireplace works very well and I strongly recommend using the Chimney Experts."

"Justin at County Line Plumbing and heating came out shortly after I called the office. Due to my leaking 50 gallon water heater started leaking! He added the situation and installed a new Rinnai on demand water heater later that day!!! Not only was the price fair, but he explained everything every step of the way! Highly recommend 10 out of 10"

"Exchanged messages with Mike to describe work needed, replace an outdoor faucet and shutoff value (previous faucet was leaking). He gave an estimate, reviewed work to be done. Replaced outdoor spigot with a frost-proof spigot, put on new value. Quick test and validation. Professional, efficient and happy with work done! Thank you Mike !"
