"The overall experience was good. Even though our roof is quirky and we have parts that are shaded, they were able to angle panels in different areas to get the maximum sun exposure. There was one glitch...the system wasn't working when we first turned it on upon approval from the electric company but once I contacted them they were quick to come out. The problem was a switch that hadn't pushed on properly and was an easy fix. We felt like they worked very hard to get the system in for us quickly and were polite and professional throughout the experience."

"My house always have an electric bill issue with the AC going all summer long and everything we used today being electronic. This issue caused me to start and look for a company that can lower my bills by installing a solar panel system or any other type of a solution. Since switching to nuclear power was frowned upon by my neighbors and the federal government, I decided solar panels would be worth a try. After looking and researching on several companies, I decided to meet and talk to the representative from Landmark construction and energy crew. Ezra and his staff over at Landmark Construction were great. Ezra walked me through the whole process and he was completely honest and accurate with the pricing and time schedule. The system that he recommended me was a 3.1 kW system with panels on the roof of the house. He had the time to tell me how will it go and what will be the final results after the system will be fully installed and working. I have a past experience work in the construction industry and I know competence and good workmanship, these guys know what they are doing and do it well. I was very satisfied with the work and with the system that they installed at my house. My utilities bills came down as Ezra said they will. I would recommend them to anyone considering solar power."

"The plumbing upgrade and dishwasher installation went very well this morning.  I bought a dishwasher for first-time installation in my older home and had texted Joshua the night before with pics of the "then current" plumbing and electrical situation.  He arrived on time with proper plumbing and electrical fittings and went immediately to work.  The used dishwasher I'd bought required more pieces, so getting those from Lowe's was arranged and he finished the entire job within 2 hours!  The only small concern (which he immediately straightened out!!) was the chrome airgap pop-up on the sink was a bit crooked, but again, he fixed that right up.   I am looking forward to hearing his estimate on some upcoming electrical  work for my patio.   I WILL recommend him to my neighbors and local friends!!

"It was very good. The installation was on time and professional. They happily made cosmetic adjustments that weren't technically necessary but greatly improved my satisfaction. They followed up regarding the incidental damage it was promptly repaired. I referred them to other people already."

"This was a fairly big project for us—adding a room and replacing the roof—but it went much better than expected. Ron handled coordination well and kept things moving even when small issues came up. The end result looks clean, solid, and well built."

"We loved working with Repair and Remodel Experts. They were
professional, polite, accommodating and stayed on task. They met our
deadline and the work they did was fantastic. Being a church, we
appreciated their work ethic and the demeanor of their crew. We didn't
have to worry that we would have visitors who might hear inappropriate
behavior or language coming from the construction area (which was right
next to our current office space.

FAQs for electrical wiring or panel upgrade projects in Portola, CA

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.
