Very pleased with all the upgrades and solar installation. Sam and Jediel were very easy to talk to and very responsive. After several meetings and great explanations of how the system is sized, priced, etc... we decided to go for it. Not only did we install Solar, we upgraded HVAC system, pool pump, and added blown insulation to our attic. The Next Door team has been very professional and responsive through out the whole process. Sam just recently walked through our first DWP bill to explain how it should be read to make sure our solar power generated is accounted for correctly. I highly recommend these guys to anyone interested in going solar. Quick, clean, and best of all, very responsive whenever I had a questions.

Very responsive, quick installation at a fair price. Johnny was super responsive and the whole process only took a few weeks start to finish!

Great company.
No company is perfect, and though the work next door did for my house was wholly excellent, the true sign of a great company is what happens when things might not go exactly to plan, and in that regard, next door is truly 5 star. the best part of this company is Johnny, when things needed to be fixed, he is instantly available and on it!
This continues today, with him helping fill out a form for my insurance over a year later.

I recommend this company fully, you will be very happy with them.

Working with Sam, Josh, and the rest of the team at Next Door Home Upgrades was pleasant, informative, speedy, and I didn't feel like I was getting the hard sales pitch that so many other solar companies have given to me. They were able to work with me to size the system for my needs, rather than over-sell, and their estimate was $5K less than the other company. The cost difference may have been the size of the system, but that just goes to show that Next Door was right-sizing my system rather than up-selling me. Sam visited multiple times to explain things to me and go over my LADWP bills, and even came by and washed my panels after the ash build-up from all the fires. They have definitely gone above and beyond in the service department! I would highly recommend.

Cannot say enough about Sam, Johnny, Mando, Josh and the Next Door team. Sam first came to my door over a year ago when I was interested but not ready to make my home improvements. I interviewed a half a dozen different solar contractors and they made the best impression and had very fair pricing. Very motivated as well as pragmatic about what was needed and what was not. The re-roof and solar install all happened much faster than anticipated, and all of the permitting and paperwork was handled efficiently and passed inspections immediately. I would highly recommend them for your solar and home improvement needs.

I worked for this company as an Internship and it is the most truthful company I have ever worked for. Sam, Johnny, Josh, stand for excellence. I highly recommend going solar with them. I enjoyed and am thankful for their internship.

Adam, Salvador, Mike, Greg, and Johnny are the all star solar installing team. From site survey, design, to install they were great to work with. I got 24 panels installed which looked like a multiple day job, but they knocked it out in one. The install was clean, organized, and works beautifully- Thank you all again! I couldn't recommend this company more!

Johnny and his team were amazing. I had a special situation that fell outside of normal solar installation offerings and most companies wouldn't help me. When I explained the situation with Johnny, after some consideration he decided to take the project on and gave me a very, very fair price. His team was on time, professional, and did an amazing job getting my solar installation installed very quickly while also done right. They always kept me up to date on the next steps and I just can't say enough good things about them. If you need solar, you will definitely be in the right hands with Johnny and the rest of the Next Door Upgrades team.

Next Door really helped us out with a Solar project that was stuck uncompleted for nearly a year. We had equipment purchased, but needed help with installation services. All our initial questions were answered clearly and quickly, and without extra up-sells or sales talk. Johnny's knowledge of the business, equipment, and permitting was spot on. The Next Door crew were able to pick this up easily and the install itself was only a day. Johnny also went above and beyond with dealing with our city permitting process which is what stalled the project initially. We are very happy with the install and finally at long last producing solar power! Thanks Next Door!

Jonny went above and beyond . He was non pushy and very matter of fact when he came over After dealing with a bunch of pushy used car salesman trying to sell me solar , I immediately decided to go with him trusting his attitude . He got the job done on time for the end of year rebate even after rain days and having to hand the job off to his partner as he was going on holiday . Instal went smoothly with a nice trustworthy friendly crew . Very honest and all round an enjoyable experience which is unusual these days .
