"Table Mountain Electric was really great. They were the most efficient of all the electricians that I interviewed for my electric panel replacement. They were able to provide a quote for the lowest cost panel replacement from only a photo I provided. They also were really flexible in allowing me to coordinate the replacement of a piece of siding behind the panel after they had taken it off. Lastly they helped replacing a GFCI outlet for me that wasnâ t working. I couldnâ t recommend them more highly. Thank you!"

"Robert was extremely friendly, professional, and knowledgeable. He was able to fix a switch in my elderly father’s kitchen on the same day that I requested the service! He had everything we needed - new wiring, switches, switch plate, and he even had a new light bulb for us to put in the fixture! I will definitely consider hiring him for any future electrical jobs/concerns."

"I will use them again and would recommend them to anyone needing home electrical repair. They managed to get my job scheduled and did a great job of keeping me informed about when they would get here. They confirmed that the issue was a wiring problem within minutes. I choose to fix the issue myself so they didnt charge me for the visit. Outstanding customer service."

"Anyone looking for quality electricians, do not hesitate to contact Epic Solar & Electric! Just had them replace and upgrade our old Federal Pacific panel, run a sub panel to the garage, and bring everything up to current code. They were on budget, on time, and great to work with. Highly recommended!"

"I’m extremely pleased with the work Jon from TORQ Electricians recently completed in my home. This project was much larger than his visit the week before, and once again he delivered outstanding results. He replaced switches and outlets throughout the house, many of which had begun to fail due to age, and the upgrades have given us real peace of mind when it comes to safety. Jon also made several thoughtful recommendations—installing dimmer switches in the kitchen and study, and suggesting a different dimmer style for our living room ceiling fan. These changes have noticeably improved both the functionality and the atmosphere of those rooms. He even identified and replaced a GFCI breaker in the panel that wasn’t up to code, ensuring everything is now safe and compliant. The work has refreshed the look of our interior, and we couldn’t be happier with the results. We’re very glad we chose TORQ Electricians and highly recommend Jon to anyone needing professional, reliable electrical work"

"I'm so glad we went with JM Electric to replace/upgrade our electrical panel. They were fast, efficient, professional, courteous, and above all gave great advice. They even installed my husband's new garage heater after installing the designated electrical wire for it. I have no clue as to what or where the wires go beyond the outlets themselves. I just mentioned what we needed, Josh and Zach explained everything prior and handled everything on installation day. Definitely will be hiring them again if we ever need more electrical work. Thanks again JM Electric! (Josh and Zach)"

"We needed more power and Zach worked with CORE to get our new transformer installed. Great communication; very responsive. High quality work and attention to detail. He went over and above with our upgrade and install of hot tub. He even showed me how to operate the new hot tub! He is now my go-to guy for any electrical needs in the future! It doesn't get any better than this."

FAQs for electrical wiring or panel upgrade projects in Littleton, CO

A whole-house surge protector blocks voltage spikes from lightning, grid issues, or even large appliances before they can fry your wiring or electronics. By diverting excess current at the main panel, it shields everything from your HVAC to your phone chargers and can extend the life of pricey appliances. Homeowners in storm-prone regions or with older panels see the biggest payoff, but any home that relies on sensitive electronics benefits.

Most whole-house surge protectors work for two to three years. Low-level spikes—too small to notice—hit your panel every day and slowly wear down the internal components. Once the unit’s capacity is depleted, it can’t prevent a larger surge, so plan to replace it on schedule (or sooner if a major lightning strike occurs) to keep your electronics and HVAC equipment safe.

A surge protector begins guarding your circuits the moment an electrician snaps it into place. Whether the spike originates from a nearby lightning strike or your fridge kicking on, the protector shunts the extra current to ground before it can reach outlets or hard-wired systems, such as your AC. That instant response is why a small upfront cost can save thousands in appliance repairs.

The unit mounts on or next to your main electrical panel. Type 1 models sit on the supply side, catching outside spikes before they hit the breaker. Type 2 devices snap inside the panel and tame surges that start within the house. Either way, placement at the panel lets the protector guard every circuit at once.

Plan to swap the device every three to five years—or sooner if you upgrade your panel, add high-demand appliances, or notice flickering lights and tripped breakers. Relying on a maze of power strips is another red flag that your current setup isn’t keeping up. Replacing the surge protector at these milestones keeps your electrical system on safe footing.
