I love Sierra Maintenance. The ease of scheduling an appointment, payment options, customer…read moreservice, the actual service and results have not disappointed. A couple of years ago I noticed the amount of energy we were supposed to be getting with our solar panels had severely decreased as our SMUD bill increased. Someone recommended getting the panels cleaned. I saw a sign for Sierra Maintenance leaving our neighborhood and decided to give them a call. After they cleaned the panels, I noticed a lower SMUD bill the next month and in the subsequent months and even to this day. They also send before and after pictures which show just how filthy the panels can get. They also cleaned our gutters this time which I didn't realize had a ton of gunk in them. Our home is two-story ~ 4k sq foot. We have about 12 panels and it was ~$200 to clean them plus another $360 to clean the gutters. Excellent company, which I will refer to others as well as use again next year.

I've gone through a lot of companies before finding them, and none came close in terms of consistency, professionalism, and actual results. Our home isn't easy. We have massive glass panels, some reaching 22 feet tall and 30 feet wide. It takes precision, the right equipment, and a team that actually knows what they're doing. These guys handle it without hesitation and the finish is always spotless. They take care of everything for us. Windows, gutters, solar panels, driveway, concrete, and more. I also use them at my Serrano property and on my flips, and they show up the same way every time. No shortcuts, no excuses, just solid work. If you're tired of hiring people who overpromise and underdeliver, call Will and his team. They're the real deal.

Once they finished the first half of my house upstairs, the gentleman asked me to take a look, and if there was anything that they missed or I wasn't satisfied with, they would fix, but by the time they finished the second half of my house I was in a hurry for an appointment so I didn't get the chance to double check the rest of their job. The next day, when the sun was shining through, I noticed some marks that were missed and some water spots from areas that maybe dried before they were able to squeegee it. I contacted the company and he sent them out right away on the next business day to take care of it. I highly recommend this company! Thank you for the great service! Will definitely use again in the future!

Some confusion going on. I had power washing done on my home. I was quoted a price by phone, but…read morereceived a different, higher estimate by email. It was no big deal and I agreed to the higher price, but the technicians came to do the work with the lower price. Again, no big deal, but still confusing because it's not clear what I'm paying and price should be clear (especially if you are pre-writing a check). I confirmed the time of my appointment on several occasions which made it confusing when my technicians arrived an hour later than they should have and I had to ask for an ETA on their arrival. I suggest rather than committing to an exact time, provide a range and flexibility. That way customers can decide if that range works for them. Being on time and providing status updates if you're going to be late is a professional curtesy especially for customers on tight timelines. The cleaning was done nicely, but I did later notice spots in corners that were missed (i.e., behind doors). The front porch area was cleaned, but then the technician blew leaves back on it. They do answer their phones unlike other competitors that you just cannot seem to get ahold of no matter what. However, their power washing is a lot higher price than other competitors. Unfortunately I don't have time to have them come back out and fix anything they might have missed. I'm strapped for time as is. I'd work on communication, attention to detail, and leaving the place clean. Also, consider putting before and after pictures in some sort of written professional document like a PDF you can leave with the customer same day with a receipt before you leave.

Otherwise, Edgar suggested that the "workers" come and clean it again, but I don't have time to be home again and police it. We told the person who was supposed to clean the windows in the house 10 times not to leave the door to the terrace open because we have a cat. Elementary things, but apparently everything is extremely difficult. There is no standard for the work process, so it's clear that there are no professionals, but a person can learn anything, as long as he wants to.
