"We had a signed agreement for electrical work, I paid half up front, and on the very morning they were supposed to show up, they called to say they ?couldn?t do it for that price? and wanted more money. In my opinion, that?s unprofessional and felt like a bait-and-switch. If you can?t stand by your own quote, don?t take the job and my deposit. Pulling this stunt on the day of service showed, to me, a complete lack of reliability and respect for customers? time. I?ll gladly take my business elsewhere, and I think others should do the same."

Our services range from hanging a tv to doing a fully automated home or business. We service the Houston Metro typically inside the beltway and down 45 to Galveston. We offer sales/Installation of high quality electronics that match the big box stores. Difference between us is smaller margains and much better service and installation!. Plus, after the job you can get us with a phone call and actually talk to the people that did the work! We are a small company that is 95% word of mouth. So making customers happy beyond the job is important.

"We had a R59 cable installed by the builder which was a problem from day one. The reason we took so long to replace it was we were concerned about the look and the difficulty replacing a cable that was literally built into the structure so it couldn’t be pulled through. MediaTech found a routing that looked planned and hidden even though space was tight in the attic. Result: looks good and no more TV interference and inoperable modems."

FAQs for electrical wiring or panel upgrade projects in Alvin, TX

While homeowners with substantial electrical knowledge might technically attempt a subpanel installation, most local building departments require permits and inspections for this type of work. Professional electricians understand local code requirements, can obtain necessary permits, and ensure the installation meets safety standards. Given the significant safety risks associated with incorrect electrical work, most homeowners benefit from hiring a licensed professional.

A standard subpanel installation takes an average of four to eight hours. This timeframe may extend if you're installing multiple subpanels or adding specialized circuits like those for spa equipment. Factors such as difficult access points, complex wiring paths, or permit processing times can also affect the overall project duration.

Adding a subpanel doesn't directly reduce electricity consumption or lower your utility bills. A subpanel simply redistributes power from your main panel to additional circuits. However, organizing your electrical system more efficiently may help prevent overloaded circuits and the associated problems. For actual cost savings, consider energy-efficient appliances and lighting instead.

The appropriate subpanel size depends on your specific electrical requirements. Consider the number and type of devices you'll be powering, potential future needs, and the capacity of your main electrical panel. An electrician can perform a load calculation to determine the most suitable amperage rating for your situation, ensuring you have adequate power without overpaying for unnecessary capacity.

A main electrical panel connects directly to your utility's power supply and contains your home's primary service disconnect. It distributes electricity throughout your entire house. A subpanel, by contrast, receives power from the main panel and redistributes it to a specific area of your home. Think of the main panel as the primary distribution point and the subpanel as a secondary branch that extends your electrical system's reach.

While electrical upgrades aren't as immediately visible as kitchen or bathroom renovations, they can contribute to your home's functionality and safety. Prospective buyers often appreciate updated electrical systems that can accommodate modern power demands. A properly installed subpanel that provides additional capacity for workshops, home offices, or future expansions could be an attractive feature for certain buyers, though the direct impact on home value varies by market.
