A top tier service provider and representative for your company!

Adam and Parker did an outstanding job for us. They installed outdoor lighting, and added and moved outlets to more accessible locations inside. We’ve seen Adam supervise and train newer employees over the last several years, and his vigilance of their work, positive encouragement and feedback has to have been a major factor in the growth of your company.

Another Great Job by TE Certified!

Last year TE Certified did an excellent job adding the 240 outlet for our car charger. It was easy to trust them for multiple tasks needed for our bathroom remodel. Wayne showed up on time and did a terrific job on the four different items needed for our remodel. He kept us updated throughout. Everything works great and looks great. We could not be more pleased.

Job well done!

Repeat customers, and once again Andrew was a complete professional, and a pleasure to have in our house. The work wasn’t easy - pulling new lines from the basement to the attic, or the equivalent of 3 stories - without cutting any holes in existing Sheetrock. The work was done quickly and thoroughly cleaned up afterward. Excellent job!

During our visit, the customer mentioned they had a high water bill. They also mentioned that Cobb county had recently come out and notified them that they have a leak somewhere. Upon inspection I noticed a small amount of water coming into the basement from the water service penetration. I spoke with the customer about solutions. An estimate was approved for a repair to be made. I dug up near the foundation of the home. A leak was located just before the water pipe enters the basement. The existing 1” pex pipe was improperly installed. Soft copper was installed through the foundation and wrapped in burial tape. Each side of the foundation wall was sealed with hydraulic cement and tar. A new pressure reducing valve and main shutoff valve were also installed in the basement. These repairs were tested for leaks and functionality after completion. Thanks for choosing Te Certified!!!

Arrived on site and customer stated she would like a news drain ran from the washer box, and needed two new water lines ran for the washer box as well. I went ahead and replaced the washer box and also replaced the drain to the mainline as well. The wall in the garage was already exposed , which allowed me to work from behind. I then ran a hot and cold line from the basement and into the washer box from the previous exiting penetrations water lines. Once all hooked up I pressurized the lines and checked to ensure proper functionality. Washer was not hooked up at the time , customer state she was going to finish painting the room before hooking up the unit .
