"Our job was a first-class operation from start to finish. After the break was repaired, Armando ran a camera and found lots of standing water. He recommended hydroflushing the pipe, which cleaned out a lot of roots, and then he was able to see further up the line, and found an even worse break. After digging up more cement and excavating more pipe, they realized that they had to undo the first repair and replace about 10 feet of the pipe. Armando also recommended that we install a two-way clean-out near the house, which would be set flush into the new cement, and would make dealing with any future problems much easier. All the workers were polite and friendly, and did excellent, careful, and thorough work, despite the 100-degree plus heat. Armando is especially outstanding: he is very knowledgeable and experienced; he explained things very well; and he kept in good communication with us about when the workers were coming (they were always on time). He applies himself to the work with energy and enthusiasm, and treats the customer with consideration and warmth. When the job turned out to be much more complicated, Armando gave us a fair price for the additional work, and also gave us a discount for using Angie’s List. I cannot remember a better experience with a home repair contractor!"

"They initially re-plumbed our entire house years ago so we are still under a service contract with them. They do excellent work. We have had no problems with them. They were very professional. There were only about two of them here at a time and they come do whatever they have to do and then, the construction crew came in after them and did what they had to do. We are very pleased with them. A lot of companies would not work with construction crews that way, but they do."

"This is the best service I have had in a long time! They were quick to respond and come to my home. They repaired my toilets several times and recommend replacements due to the builders putting in the cheapest toilets there are. I will never call another plumber again. Thank you PM Prestigious Plumbing!"

"During a house purchase US Trenchless came out and scoped the main sewer line.  They gave me a detailed report.  They also gave me a quote to replace the line.  After doing some comparison shopping US Trenchless beat a competitors low bid by 10%.  The work was done on time and professionally.  I would recommend them and use them again.  Ross and Tim were great."

"In June of 2010 my house flooded due to a faulty toilet tank intake line.  Forever Wood Construction was there within 2 hours & begin the steps needed to start the repair of my home.  They helped me move all my belongings out of the way so they could remove the water damaged part of the walls & the damaged flooring.  They set up blowers & dehumidifiers throughout my house to dry it out so they could proceed to put it all back together.  They totally matched the texture on my walls & you can't tell that I've ever had a flood or had any portions of the walls redone!  They even fixed some long standing electrical issues for me.  Great company!  I definitely recommend this company to others."
