"Ezra and Charles are very friendly and personable. That is, when they want to take your money. What good is a 12-year warranty if you start ignoring your customers at 2 years. I needed my HVAC replaced. Because the HVAC sits on my roof, I decided to redo the roof too. Ezra and Charles came out and were really friendly so I immediately had a good impression of them. Even though it would’ve been cheaper to go with a roofer and a separate HVAC company, I decided to go with Landmark Construction Crew, aka Landmark Energy Upgrades. I figured it would be a more seamless process for one company to do both. I got this done in December of 2016. The thing with a roof is that you don’t know if it’s a good job or not until it rains so I waited to write a review. Around January 2018 ( a little over a year later ) we got some much needed rain but unfortunately, I had a leak coming from one of my vents. I emailed Ezra and he sent out a roofer. The roofer came, looked at the vent, jumped up on the roof for ten minutes and said he was done. Months later, it rained again, it leaked again, I emailed Ezra again. I decided to take a closer look at the vent and noticed that there was sunlight in the ductwork. I figured sunlight equals gap somewhere. When the roofer came, I told him and he said it’s nothing, probably just a reflection, without even taking a look. Then the roofer tells me that the next time there is a leak, I need to call the HVAC guy because it’s not a roof problem. I couldn’t believe it so I told him that HIS company IS the HVAC guy!! I used one company to do the roof and the HVAC so there is NOBODY else to blame. So, he jumps back on the roof and was done and gone in 10 minutes. About a month goes by and the rain is back and so is my leak. It’s 2019 so it rained a lot this year. Good for California, bad for me. So, I emailed Ezra again. After a few weeks, no reply. So, I email him again with pictures, a few more weeks go by and no reply. So, I call him and he picked up the phone. He sounded surprised to hear from me (probably didn’t recognize my phone number) and I start telling him about the leak. He said he didn’t get my emails but just text him my address and he’ll send somebody. A couple of weeks goes by and nothing. So, I text him again and after weeks and weeks of waiting, no reply. I’ve emailed, called, and texted so, at this point, it’s very obvious he’s avoiding me. If you are looking for a friendly company that is willing to take your hard-earned cash then Landmark is for you. But if you’re looking for a company that is accountable for their work then look elsewhere. I know I am."

Sunrun
Sunrun
Sunrun is leading the charge to create a planet run by the sun. We are building a more sustainable world, by making solar simple for over 200,000 customer's in 23 different states!
"Sunrun installed a bad roof on my house. After many months of emails and phone calls, they never sent out a repair man. Finally, under duress, I signed a form from Sunrun to use my own contractor. I signed under duress because they said they couldn't get a repair man and that this was the only way I could get my roof repaired, and there were driving rains. I told I didn't want to be personally responsible, and that's only thing I asked. But after the contractor fixed the leaks, there was more hidden damage that emerged and more leaks. They told me they won't fix the roof. The bad roof they installed was so bad that one company wanted to charge me $23,000 to fix it. He said the roof was so bad that really it should be replaced. And boy, when he looked at it, he sneered in disgust. Why did they not simply repair the roof after the first phone call. Eventually, they sent me an email with lies, such as "since the roof no longer has a running leak, Sunrun is not responsible for a repair." A blatant lie. I assumed this was an underhanded tactic written by a lawyer to fool the court in the event of a lawsuit. I thought Sunrun was a legitimate company. Even the Sunrun claims manager apologized to me for my treatment, and she said the higher ups were orchestrating everything. She seemed to be trapped in an immoral circumstance because the bosses simply wanted to get out of paying for that roof at all costs. Even from the beginning, they continually tried to get me to "work " with their contractor. They said they couldn't find the contractor and only that particular contractor could fix the roof. Why were they telling me all this. I told Sunrun, that I purchased the roof from them and to leave me out of such conversations. I truly feel this matter is about greed and avoiding the cost of their damage. They have a lot excuses, but I felt from the beginning, everything was a dodge or a put off. It's been two years and my roof still leaks. This is so cruel. I'm a senior citizen. The stress has been affecting my health and making me I'll."

"Trust has been broken by nearly everyone I have talked to at Smart Energy Today/Lumio. It has been over EIGHT months now since my first signing with your sales representative, Josh Miller. Summer has come and gone, and we STILL have no working solar panels with zero communication from anyone in your organization on when this will be completed. The absolute TERRIBLE experience we've had was as follows: 4/14: Spoke with Josh Miller. We were told if we signed that night, we would be given 3 months worth of payments. Signed that night. 4/15: Welcome email received from Smart Energy Today with timeline saying target 6-8 weeks from finance approval with picture showing maximum timeline of 12 weeks, which would have been 7/15. 5/10: Got an email requesting for documentation with my name on the property. House is under my husband's name, so we needed to add his name to the loan. 5/24: Signed new documents with my husband's name on it. New maximum timeline should have been 8/24. 6/22: Solar panel was installed roughly around this time. After the install, I got a physical copy of a timeline showing a timeline maximum of 84 days plus one step that had a variable date range. New maximum timeline should have been roughly 9/22 without knowing what the variable timeline is. This was the final update to the timeline I got, so as far as we are concerned, this should have been the target date. 6/23: Inspection was supposed to happen in the morning. Waited until 1 in the afternoon with no one showing up and no word on when the inspector would be coming, we needed to reschedule due to work. I was told someone would call me back to reschedule, but no one ever did. I had to reach back out to Josh for help to get the inspection rescheduled. 7/2: Got letter from Service Finance Company that our first payment is due 7/28. We asked Josh about this since only the solar panels were installed, but our main panel which needed to be replaced due to age was not installed yet and was rolled into the loan. Josh acknowledged that this seemed odd and would look into it. 7/21: We got our first bill from Service Finance Company. Sent to Josh again, he said he'd look into it.8/16: Main panel replacement occurred. On the same day, we got a call from Service Finance Company that we are 19 days overdue and will be going into collections soon. Reached out to Josh again about this, and Josh promised he'd pay for the late fee. 8/18: Finally got a gift card from Lumio with the first three months of payments that Josh promised us. Since we had to resign the loan for a new amount since the main panel was rolled into the loan, the gift card was for 3 months based on the old amount, not the new amount, and it did not include the late fee that Josh promised. Was told I would get an additional gift card for the remainder by a representative who called me to confirm I got the gift card. 8/19: Got a survey from Lumio about the solar panel install. I took the survey and fully explained the horrible experience I had up until that point. The survey asked if I would like someone to contact me, and I said yes. To this day, no one has contacted me. 9/2: City of Seattle came to inspect expecting a Lumio representative to be present, but there was no Lumio representative. Josh said that no Lumio representative should be onsite. Via email, Jennifer said a Lumio representative should have been onsite. I told Jennifer Josh said this wasn't necessary, and Jennifer said there should have been. Rescheduled inspection. 9/13: Got a text from Jennifer saying I needed to schedule an inspection again, which made me think the previous inspection scheduled on 9/2 did not occur (error on her part). 9/17: Texted Josh asking for a follow up on the gift card. Zero acknowledgement. 10/12: Texted Josh again about the gift card. Josh texted me an email screenshot Alexa Gamble sent to Rachel, AJ, Catherine, and 7 other people for follow up. 10/20: Text from Ivie to schedule final electrical inspection for 10/27. I texted back requesting for 10/28, but didn't hear anything back from her. 10/28: No one shows up. 10/31: Text from Ivie saying that the technician had an emergency and her text to me never went through, now the final electrical inspection is scheduled for 11/10.11/4: Texted Josh about the gift card. Zero response. 11/10: Lumio inspection with Seattle City Light. Was told additional work needed to be done. It has been two weeks, and I have heard nothing back from anyone about when that would be scheduled or take place. This only includes the correspondence I've had in writing with your organization. This does not include the countless phone calls I have made to follow up with your inability to provide clear communication and follow through. In writing this and reliving the experience I had with your company, I am completely astounded by your organization's inability to follow up your customers. It's not just one or two, but multiple people who have dropped the ball with communication with us."
