Just fantastic from start to finish. We were interested in solar and met with Josh for an initial consultation. He was incredibly informative and applied zero pressure. He explained the process, what our expectations could be, and the various programs and incentives we would be eligible for. We took about two months to mull it over and met with two other companies and there was no doubt who we felt most comfortable and confident with. After we signed, Josh handled all the hoops of the Burbank permitting process flawlessly and with great communication. The installation was perfect and his crew were punctual, clean, and polite. After installation, Josh again handled all the hoops of the inspection and Permission To Operate paperwork beautifully. We are now up and running and really happy with the results. We cannot recommend Josh and the Next Door team highly enough.

PW3 Batteries

Next Door Home Upgrades is the dream team of solar. They made the solar process a breeze with constant communication and clear expectations. Johnny at NDHU is friendly, knowledgeable and trustworthy with your solar needs. He sized our system perfectly with 20 panels and two Tesla PW3 batteries and plenty of room to grow if our demands increase. After researching solar and seeing the horror stories about Tesla installation taking forever and customer service nonexistence, Johnny was able to provide the local installation and top tier customer service while still installing the Tesla equipment we wanted. The whole process took less than 2 months (closer to one month) from start to finish and the install team at NDHU was fantastic. Started process on 8/19/25, installed on 9/11/25, city approval 9/15/25, pending SCE PTO. We had 3 quotes (Tesla, NDHU, other) which all were similar in cost, but NDHU is the way to go with their top-notch customer service and knowledgeable electrician/installers. If I had to do it all over again, I would not have changed a thing. If you want solar done the right way the first time, Next-Door Home Upgrades is where to go.

The Panels!

Josh, Johnny, and Sam have done an amazing job with our solar project. I have now referred multiple family members to them. If you're short on time, to summarize the long paragraphs ahead: Yes, you should do business with Next Door Solar. I got several quotes for solar. I got one from Next Door as well as one from Sunrun, a few from Electrum, and one from Better Earth. Sunrun was the most expensive however after looking at the reviews and equipment I ruled them out. Better Earth was reasonably priced but I felt pressured by the sales rep. Electrum, an online service, provided multiple quotes that were all a couple grand cheaper than any of the other quotes but when dealing with an expensive project on my home, I would have preferred to talk to the companies directly or even have them see the house instead of just me uploading my electric bill, reading a brief description on them, and getting a price. I just didn't really understand how those companies were set up and lacked confidence in the quality provided and long term sustainability when offering a cheap price and not being very hands on. There were 2 initial reasons why Next Door was a no-brainer to me. The first being that I felt confident that they were going to provide great customer service due to meeting the owners, the company being local, and talking to multiple of their clients who are very happy with them. Secondly, after investigation, the way Johnny has structured the business is friendly to long term success. That was a big concern for me due to a high turnover rate for solar companies the past couple of years. They don't just specialize in solar which means they can focus on different revenue streams in events where demand for solar is low. Furthermore, it is my understanding that they are very lean and don't have giant overhead costs like most other companies. So not only was I confident in their customer service, I was confident in them actually being around long term to be able to provide that service which is important with batteries, Net Energy Metering Changes, and regulations in the future. Now after having the team install the panels and get everything up and running. There are a few things I must mention. They did not subcontract the install which you could tell due to the seamless communication and expectation setting from Josh and the team. The workers were on time and although it was messy during the install, they did a good job cleaning up afterwards. They also walked me through the project beforehand so I understood where everything was being installed. They even went through the reasoning on where to place the combiner box so it doesn't face the backyard and take away from the aesthetics and placed it on the side of the house where it was more out of sight. The quality of the installation was great, no holes poking through the roof or crooked panels which you hear horror stories of. The inspector found no problems and signed off on the job during the first visit. Josh recapped the project with me and also explained a way to avoid the power access charge from LADWP by being on the correct service plan which I then helped my coworker who had gone solar previously switch as well. He also walked me through the app and how to verify that everything is working correctly. I am impressed with how above and beyond this company has been from sales to install to post installation. I look forward to working with Next Door for years to come and I hope this review serves as encouragement for other homeowners to work with them as well. Also I almost forgot to mention their nonprofit work. I won't do it justice trying to explain their impact but it is refreshing working with a company that is rooted in gratitude and giving back to others...

So my friend Gus referred Next Door to me for my solar project and I got a call from the owner himself, Johnny who ended up becoming my rep. From the get-go, Johnny made sure I was informed and assisted in every single step up to the finish. Look, it's not so often I inquire about solar for my home but when I finally did, they answered every single question I had. I also had a minor issue with my roof and they had to fix that before they were able to install my system, which was great because I would've never noticed that. I had some leaks before but so far, my roof feels brand new with my new solar system. I'm also very particular with how everything looks and thought my house would look weird with the solar panels, but it looks AMAZING (pretty cool that I even got a drone shot of my house, hah!!) Every single person I've spoken to at this business was very attentive and nice. I've already referred them to my friends and family, hopefully, they make the right decision to go solar and go with Next Door!

I want to take a moment to give a huge shout-out to Lee Yosef with AAA roofing…read more Recently, I had a situation with a homeowner who was experiencing a leak around a window and wanted a second opinion. Wanting to do right by the homeowner, I reached out to Lee and asked if he'd be willing to come take a look and provide an unbiased assessment of whether the issue was roof-related and how we could best solve it. Without hesitation, Lee rearranged his schedule, met me and the homeowner on site, clearly explained where the issue was with the window, showed video to clearly explain the issue, and helped us come up with a solid solution. His professionalism, knowledge, and willingness to help spoke volumes. This experience is a great reminder that even though we may be competitors, we can still work together, collaborate, and help one another for the good of the homeowner and our community. That kind of integrity is what truly sets good businesses apart. Lee with AAA Roofing is a prime example of what it means to be a good neighbor and a great business owner. I'm grateful for his help and proud to work alongside professionals like him in this industry.

AAA Roofing Services absolutely deserves 5 stars. They fire‑proofed my roof and handled everything…read morewith total professionalism -- none of the contractor hustle you dread. They identified and fixed problems I wasn't aware of, delivered the job exactly on the promised day, and stayed right on the dime. Out of five bids, theirs was the most competitive. Lee is fantastic to work with. Highly recommend.

So, after all this record setting rain, my house sprung several leaks through my Spanish Tile roof…read more I spent a few hours calling around and checking references until I got to G & C and contacted Caesar, the owner. I left him a voicemail with all my details. He called me right back and said he could be out within a half hour. Mind you, it was still raining. Caesar made it out within the half hour that he said he would. We went over all the leaks. He jumped up on the roof and ran around like he was on the ground floor. Obviously, greatly experienced at walking on slippery Spanish tiles. Turns out my sky light was improperly designed for torrential downpours. Plus, I had several blockages in the alleyways of the roof connections due to years of debris that needed to be resolved. Finally several of my vents needed to be resealed. Anyway, Cesar gave me a very fair quotation for all the work and said he would be able to slip me in as soon as possible, but that because of the rain there's so many problems he has to deal with. The next morning I asked him for an update, and he said I was in luck because one of his clients had just canceled and he could come out and get the job done, today. Caesar and his crew came out and did the job in a few hours and everything seems to be in great working order. I am very satisfied for the work he did, and the value that he and his team offered - in this trying situation. I am sure that some other shady roofers would have gouged me by charging a fortune and overworked my rooting needs, but not Caesar. He seems like an honest person, good commentator, and a good businessman.
