"They were very professional, timely & cleaned up after themselves. Although the original quote they gave me $295-there were additional issues with the toilet so the final cost was $445.00"

"Jose and his crew were great! He came highly recommended by a neighbor, who had hired them to completely re-plumb her house. We needed our 75-year-old sewer line replaced: I got an estimate within a day or two of requesting one, and he caught a problem with the original installation that other contractors had missed in their inspection. Jose and his crew did the work as promised and cleaned up the site every day---spotless! We had a small tree that was growing near the line which they managed to save, which we didn't think was going to be possible, and they managed to dig a huge hole in our tiny front yard without a lot of impact to our other landscaping. They handled all the permitting and inspections, too, and made sure I got copies of all the relevant paperwork for our household records. I highly recommend Pipe-Thru, they were so easy to deal with and completely professional all the way. They charged a fair and reasonable price for the work. I will definitely call them when I have any other underground piping issues--including installing electrical conduit to our backyard shed, which we want to do in the future. Can't recommend them highly enough."
