"Prompt response… very professional! I have been without a sink for two weeks, called a few companies and no follow up.. Tejadas was able to fit me in right away.. they were at my home on time and did a great job cutting my granite countertop and positioned my sink to get installed by the plumber… I would definitely hire them again for any future jobs"

"I love this virtual service. My Whirlpool Duet was flashing an error code related to the drain pump. After cleaning the pump, the error was still showing. I set up an appointment with Neli and spoke with a very knowledgeable representative. He assessed the machine and was able to determine the likely cause of the error. After the appointment, I was sent information on ordering the replacement part and how to set up a call to install the new pump. I would use Neli in the future for any appliance issue!"
