Thank you , Griffin, for your excellent service on June 11. You got everything going right. You are pleasant and skillful at your work. We won't hesitate to call on you in the future for our electrical needs.
Excellent Service!!
This is the second time Steven has helped solve our plumbing issues. I specifically asked for him this time because he was so helpful, thorough, professional and pleasant the first time around. I highly recommend him!
Very thorough
Dee was so friendly, professional and helpful. I crushed my ankle and am in a wheelchair presently. He offered to bring my trash bins in from the curb & p/u a delivery for me that was left outside. He described what to expect and worked all day. He has almost 19 years plumbing experience, I highly recommend him regarding your plumbing needs.
Please with the service and result.
Mario did a wonderful job. Pin pointed the problem and then gave us our options to choose to fix it. Once again TE came to the rescue!!
Griffin was super. He called ahead, arrived on schedule and repaired the problem with wiring in a very professional manner. Very impressive.
The service and explanations of work that had to be done were very helpful and accommodating.
Great service
Very pleased and great service. Thank you!
Excellent service! Patient and helpful.
Blake did an excellent job, neat, quiet and unaware someone was working in my house. Was also very patient answering my questions. You are lucky to have him as an employee.
Shane was the absolute best in troubleshooting our AC problem! He was very informative and polite. We also appreciated TE sending a tech sooner than expected.
Great thorough service
Griffin and Dakota did a fantastic job. Called to give an eta, were here on time, addressed the issue and gave input on an important electrical issue that I arranged to have repaired. Very satisfied.
Ryan and Reese were very personable and did a great job installing our toilet. They also discussed our future needs
Great and prompt company (TE) response to replace a kitchen disposal. Friendly, knowledgeable and efficient service tech (Stephen). We are very pleased.
I have lived in the same house for 28 years and this was the best plumbing service I’ve ever experience.
As well as addressing our immediate concern (a “frozen” hot water supply valve), Allen Murphy quickly recognized a secondary issue that was creating low hot water pressure to the rest of the house. He explained the situation clearly and succinctly. I am (again) extremely satisfied with the professionalism, knowledge, and friendliness shown by TE Certified team members in all of my experiences with them!
Great service
Stephen & Steve both came to work on my plumbing needs. Both men were very professional & courteous. They came in, did the work & cleaned up after themselves. A good experience.
Brock was very professional and did a nice job
very good all the way
