Recommended Customer Reviews

I was pleasantly surprised with this company.
On an older home I owned in the past I made use of a home warranty (AHS) twice and had concluded that the contractors they hired to do the work were sub-par, spent 5 minutes diagnosing a problem, and then charged $80-90 dollar consulting fee to tell you it wasn't covered under home warranty. So my starting place was being very skeptical indeed!
I moved into a home a month ago and came to realize one of the lights in the bedroom wasn't working. After some of my own diagnosis I discovered that the fixture was not connected.
Despite my best judgment I decided to give the new home warranty program I was under in this house (HWA) a shot. Xavier Garza and Brandon from Sierra Electrical Services (aka Mr. Sparky), arrived and within about 30 minutes concluded that the builder had made an error and had missed connecting the light fixture and it had gone on unresolved. I had a frank discussion with Xavier around what my chances were around having the warranty cover it, and he said the chances were poor as it was original builder error. Needless to say I was disappointed, however he came back to me a few minutes later and said he was given a $500 allowance to cover problems on the spot that would be covered under warranty, and using some ""creativity"" in describing the problem, would do so. I was very pleased with this outcome, and I felt Xavier was advocating for my success as a customer.
The following week, Brandon and Xavier came back and did the job, which took about 2 hours. I was very happy with the politeness and professionalism demonstrated, and my light fixture works great now!
The only negative I would say, is that there was a lot of confusion around scheduling - tardiness (i.e. arriving outside the specified window without communication of lateness) and scheduling in the afternoon when the job should have been scheduled in the morning due to the Texas heat and needing access into the attic. Yolanda, the scheduler, needs a more organized process to managing site visits, and also work on her level of politeness and professionalism.
However, this should not overshadow the overall great customer experience I had!

So not happy with their 'service'. Made an appointment a month in advance and confirmed the business day prior. Was told they would be by between 9 and 12. 11:45 I get the call that they won't be coming because they took a different job but the could reschedule me for a couple days later. There was a reason I called a month in advance. Would not recommend.

Sierra Electric Services DBA Mr. Sparky is the best of the best. They were sent by my home warranty company and to date have only been able to do bandaid my problems. This time they made it clear the bandaid would no longer work it would require new service or they would be putting my home at risk of fire. They accomplished the task in good time and went out of their way to make my family comfortable in this record heat by hooking a generator up to my home while the power was off. Great job guys. Thank you!!!

The electrician went above and beyond what was expected. He was on time, efficient, and very knowledgeable. He took care of the problem quickly. Can't recommend them highly enough. Very satisfied customer in Taylor Texas.

One local electrician failed to return calls and emails, then another one failed to show up at the least minute. But no worries, because Sierra Electrical Services came to our rescue. Polished, professional and best of all, they responded promptly to our request for sane-day installation of numerous lighting fixtures, two of which required a scaffold for a twenty foot ceiling. Thank you, Xavier, and thank you, Renee. Finally we know where to turn when we need really good and well qualified electricians.

They are also known as Mr. Sparky..
I called them and told them my problem.. I was told they have trucks all over town including south Austin.. He was supposed to be here @ 4pm.. He calls me at 4 pm and he is at 183 and Balcones.. A good hour drive in the traffic..He said he could give me a price over the phone before I driver down south..
He said I can tell you it will cost $688.. for the breaker and labor.. No hourly fee, just $688..
I at the point felt I was fixing to be ripped off..
I called another guy and he was there in 30 minutes.. It took him exactly 8 minutes to replace the breaker.. The breaker was $7..He only wanted $50 !!! I tipped him another $20..
Saved $618..!!
Use them at your own risk..

i will never use this company!!! one of their drivers almost caused a wreck on i35!!! driving like a bat out of hell!!! i was in the far right lane, moving along with traffic and this van flew past me like i was standing still!!! no regard for the company and no regard for the other lives on the road this morning @ 7:20 am. on 9/11/15. kinda morbid, trying to take out more lives on this day of remembrance!!! way to go!!!

I had a stellar experience with this company and did not experience any of the things that the one-star yelpers mentioned in their comments. One yelper mentioned looking at the BBB website. While this company is not accredited with the BBB, they have had ZERO complaints with the BBB in the last 3 years.
My Home Warranty had Sierra Electric (Mister Sparky) come to my home to address an electrical issue. Rene came to my home at 315pm (window I was given for a technician to arrive was between 3-5). He was in uniform, clean cut and very professional. He was extremely thorough in trying to find the problem and very informative (in layman's terms). Because of the nature of the problem, he was unable to locate where the ""break"" in the electrical current was coming from. He informed me of all of the possible solutions and that he would have to contact my Home Warranty to approve the additional work and come back. I received a call from the scheduler at Sierra by the next business day informing me that the Home Warranty approved more time to find the problem and scheduled another window of time that the same technician would return (3-5). Again, Rene was at my house at 315 and he brought a Master Technician with him in order to expedite locating our electrical problem. Within an hour, they were able to locate and fix the problem, which it was discovered that another electrician from another company that had just performed work in our home had created the problem. I am so thankful for these guys at Sierra Electric and I WILL have them back to my house for any electrical issues/needs that I may have in the future.

On two occasions we have had electrical issues in our home. Both times our warranty company sent out Sierra. Both times the service was great.
The first occasion our wired smoke alarms were malfunctioning, as well as our upstairs furnace. The tech discovered that for some odd reason our smoke alarms and furnace were wired to the same circuit. They were able to fix the problem and got us approved for new smoke detectors from our warranty company which they came back a day later and installed.
The second occasions our power went out. The tech showed me our breaker box, and that the main breaker and several others has completely burned out. With no power, a fridge full of food going to spoil, and no AC in the middle of May with an 18 month old child in the house, the tech had his scheduler clear his day so he could take the time needed to replace and rewire the breaker panel so we did not have to go another day without power. He even had his boss, the master electrician, come out to assist him.
My wife and I are very happy with our two experiences with Sierra. I don't recall the name of the tech that came out both times, but he was super friendly and knowledgeable.

I had a good experience with Sierra's tech Gerzain Mendoza.
Friendly, knowledgeable, courteous, etc. I'd be happy to have Gerzain out again if we have any electrical issues in the future.
Sierra came to me through my AHS home warranty and I also hired them for a 2nd electrical job that wasn't covered by the warranty.
