Customer reviews
“Eduard came to my house and was the most professional and polite man I could have asked to show up. He diagnosed and fixed my main line clog in about an hour and a half. If I ever need Elite Rooter again I will be asking for Eduard personally.”
“What we were hoping was a small project turned into a big one. Edward was very informative and courteous to everyone. Javier helped figure out the issue, and we communicated all weekend about the project to finish the sewer line. Carlos and Lupe were absolutely amazing to work with as well.”
“Same day clogged drain response!”
