If you need an electrician in Austin Metro Area or Travis, Hayes, Williamson Counties, let Mr. Electric of Austin help you. Whether its installing, repairing or upgrading, Mr. Electric has a solution for your Austin, Round Rock and Pflugerville area homes and businesses. With around the clock availability for emergency services, our team offers several services that could benefit not only your home or business, but also the environment. Whether it’s for safety and security or specialty lighting for the holiday season, Mr. Electric can assist you with your every need.

"We had great experiences with a very smart woman electrician from Mr. Electric in the past to replace garage light fixtures and repair some interior kitchen light shorts, so they were top of our list to call for the new issues. However, when I called the person fielding the call told me they do not do repairs of exterior lights and would only replace the entire fixtures, even for the one that simply has a stuck base of a lightbulb in it because a bulb broke when we were changing it. Why would they not repair external light fixtures and only do entire replacements of them? It seems very odd. They could not refer me to another electrician who does repair external fixtures, so here I am taking a look at Angi reviews."

CMIT Solutions of Southwest has been completing cabling . IT and Networking work for residential and commercial clients for 10 years. We complete a wide range of projects, from a simple ceiling fan repair to a full electrical install on a custom home. We value customer service, professionalism and integrity. We are passionate about exceeding your expectations and would love to hear from you. We offer competitive pricing so give us a call for a free estimate.

"Showed up and spent about 90 minutes looking at the TV (which was already mounted to the wall) and talking to my husband. Said he needed a part and he had to go to Bulverde, Tx for the Home Depot (about 45 minutes away) because getting the part from the hardware store in town might be a liability. He never came back. He called a few hours later and said he had to go to San Antonio, Tx for the part. The company then tried to bill me over $600. When I protested they dropped the bill to just under $400. I have called and left messages but they will not call me back but I am getting multiple emails and text messages asking me to pay them."

Looking for a company that gives you the “warm fuzzies” and makes you feel good each time we do business together? For Emergency Services or After Hour Services, Please call 512-450-1980! When you call A-Plus, you can sense warmth, experience and knowledge from our professional staff. Family owned & operated since 1977. We service Austin & surrounding areas 7 days a week .

"BUYER BEWARE! DO NOT USE THIS VENDOR! I was duped by this company! Told me the installation of my single front iron door would be $255/hr for 1 hr possible 2 hours for 2 people. This install was 7 hours for each person or 14 hours which cost me over $1300 to install 1 door. The door was already prehung. The 2 men were walking around wasting time, pretending to look for parts such as door handles which were right in front of them in the box. This is deceptive, false advertising, and will be reported to the BBB. They didn’t even get my confirmation/approval for additional hours or work! I will NEVER use their services again. Duped!"

Home Security Systems questions, answered by experts

Some but not all security cameras have monthly fees, depending on the specific camera system and the services offered with it, especially monitored vs. unmonitored security systems. Home security companies that offer monitoring services along with cameras will charge a monthly fee for monitoring and possibly for using the security cameras. Cameras that you monitor yourself as part of your own security system will not have monthly fees charged.

Not all security systems are equal, so familiarize yourself with the many features available and any associated costs. Decide on a wireless or wired system and look at monthly subscription fees to access the service. Finally, read plenty of reviews to check out the efficacy of your intended security system.

Hiring a professional ensures optimal camera placement, secure installation, and integration with existing security systems. Professionals ensure reliable operation and can offer system customization to suit specific security needs or preferences.

Wireless cameras will not work without an internet connection. A Wi-Fi camera uses the internet to transmit footage and store the information in cloud-based software. However, there are wireless cameras that you can buy that allow you to record and save footage on an SD card instead.

Each has its use, depending on the scenario. Security doors are primarily intended to keep people out of the home, while storm doors are used to protect the home from extreme weather. Both tend to be made from heavy-duty metal and may include glass panels to allow light to enter the home. Storm doors can feature mesh screens, just like screen doors, to allow for increased ventilation and to keep out pests. Security doors rarely, if ever, have mesh screens.
