"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."

We are A-1 Plus Electrical, a Company committed to our client's projects and needs. David Saldana is a master electrician you can trust, with more than 20 years of experience in the electrical field. Our team has built a solid reputation in the community for our outstanding attention to detail and superior customer service.

"We had an underground supply line failure in the middle of the night and had to find a pro fast to get it replaced. A1 Plus replied to our inquiry quickly and got us scheduled for an estimate that day. The technician, Jose was really professional and knowledgeable in walking us thru the whole project. He really put us at ease explaining the steps in the repairs. Everyone I spoke to at the company (Griselda, Rosemary, Itzel) were all friendly and helpful. The price they quoted was several hundred dollars less than the previous quotes and it was upfront and easy to understand the breakdown. We also joined the yearly membership that offers discounts on repairs and were able to save 10% immediately on the job. The guys that did the actual repair were very nice and did a great job getting the work done. We are very happy with the work and the company and glad to have a reliable, honest electrical service we can rely on for future jobs."

"Absolute waste of time and money. I scheduled a very simple job - replace two exterior wall sconces (porch lights) with two new ones. The old ones work fine, we just want to update the look. Scheduled service for a date and time and acknowledged there is a $69 service/trip fee which is waived if you have them do the work; no problem. They even called day-of to see if tech could come out earlier than scheduled, which worked fine. When tech arrived, I explained the very straightforward job I wanted done. He looked over the new parts, and I thought we'd be good to go. Then he said that before he did anything he had to do a "safety inspection." An hour later he quoted me a multi-thousand dollar bid to replace all sorts of equipment I had no interest in replacing. And the simple job, if he did just that, would be over $550. I declined, and so it cost me $69 to have no work done and waste my time. I will either do this myself or find a local handyman. Avoid this company like the plague."

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

Electrical wiring can last between 50 and 70 years if properly installed and maintained. However, factors like moisture damage and overloading outlets can shorten this lifespan. To extend your wiring's life, unplug electronics when not in use, avoid overloading outlets, and schedule regular electrical inspections every five to ten years.

If your house was built in the 1960s and hasn't been rewired, it likely needs it. Older homes may have outdated wiring like knob-and-tube, which poses fire risks due to flammable insulation. Rewiring ensures safety and may also require updating your circuit panel, outlets, switches, and fixtures. Contact a local electrician to help with your rewiring needs.

Yes, rewiring your house is worth it, especially if your wiring is outdated. It improves safety by reducing fire risks and can increase your property's value. However, you may not need a full rewire. A home inspector can tell you if a partial rewire will bring your home up to code.

Yes, you can sometimes rewire a house without removing walls. Electricians might access wiring through attics, basements, or crawl spaces, or make small holes to run new wires. However, this isn't always possible, and in some cases, removing sections of walls is necessary to ensure the wiring is installed safely and meets code.

A house should typically be rewired every 25 years to maintain safety. Over time, wiring deteriorates, increasing fire risks. Regular electrical inspections every five to ten years help assess the need for rewiring. Staying proactive with maintenance ensures a safe, efficient electrical system and prevents potential hazards before they become serious issues.
