Brandon was great to work with and offered solutions to logistics we needed handled, specifically removal of a pool solar system on one side of my roof. Also, Tri Valley Roofing was able to quote removal and reinstallation of my electrical solar system under a single contract.

This an update to a wonderful, five-star rating that I provided to Wonderlin in 2022 after they put…read moreon our new roof and added solar provided by their sister company, Synergy Energy in Livermore. As any long time California resident knows, we don't get a lot of rain compared to other areas of the country. Because of climate change, we have started experiencing atmospheric river storms as witnessed in the last few weeks. We experienced a leak during the week between Christmas and New Years and when I called their office, I learned that they were closed until Monday, January 5. Well to my surprise. I received a call back from their office asking about the severity of the leak and whether I needed immediate help or could it wait until they had everyone back to work on the 5th. I had a bucket collecting water and the leak was small enough that I decided it could wait. On the 5th, I received a call back from the office asking if they could send two repair people that afternoon to inspect and repair the issue. I was not home but my wife was, and she said that the gentlemen were prompt and thorough and explained what they saw and what did to correct the leak. I am not writing this as a novice to the problems in the construction industry, I am now retired but worked 40+ years in the window and door portion of the industry from owning my own company and working in sales for a billion-dollar wood window company (Marvin Windows and Doors). If anyone knows of Marvin, they are a company that prides themselves in producing one of the best wood windows in the industry as well as providing exceptional service. Well, Wonderlin is right there with them. I will continue recommend them to anyone looking for a new roof and not having a lot of issues to worry about.

They responded to my request for a proposal for a new tile roof immediately and within a week of starting finished the project. My wife and I are delighted with finished product. Grover was very patient helping us select just the right tile and his son Matt kept the job going quickly despite the rain we experienced during the 7 day installation. I really enjoyed working with this family run business.

When we noticed a leak in our home, it was recommended that we have first have our gutters cleaned and checked. A good friend recommended Jeff. Jeff returned my call promptly.

Once we requested the refund from him, we magically received a call from somebody we do not know saying they would come the next morning to do the work on Jeff's behalf but any trust in this company had already been lost.

During the job, I paid an additional $200 in cash requested by the technician on site when he said some additional scope wasn't included in the $1,200 project. Later, the company stated they had no record of that payment and billed me for the full amount. I informed them of the payment and disputed the balance. I asked for documentation and clarification on their accounting, but that was never provided. Communication became focused on collection and lien warnings rather than investigating the payment issue. I was pretty shocked how aggressive they were in their phone calls and emails. I recommend that customers keep detailed records and receipts for any work done with this company.

This was our first service to clean our gutters so it had a lot of pigeon poop and a huge chunk of volunteer plants. (Hubby thought he could clean it himself someday lol) Jose was very easy to talk to. You know that instant vibe when you know a person is genuine... he and the crew were professional and respectful. Their company van is eye catching! So much pride in the design and uniforms! I like that they send videos and/or pictures of before and after. My husband is starting his service business and this is exactly what I want him to do....show customers proof of services, honesty, respect , integrity and veteran discount. Jose was so nice and humble to offer tips if my husband had any questions. God blessed us with this business. They had the best pricing among the estimates I received. I will use them for all their services and refer them to everyone! Thank you Jose and guys for your services and Veteran discount. Blessings to you and your families!

They asked for the addresses so they can get a google image of the house and give me an estimate right then and there (a lot of business don't wanna give quotes out over there phone without physically coming to the house to see) so i liked that it was straight to the point. I mentioned both houses needed to get done PLUS my mom wanted to get her solar panels washed and they gave us a really great deal and were able to squeeze us in the same day that same weekend. I got videos of before and afters on both houses , the gutters and the solar panel cleaning texted to me. And now they're gonna work on giving my mom a quote on replacing her gutters in the future because she does need to get them switched out They accept cash, Zelle , vemo They also speak Spanish Would definitely recommend these guys and do business with them again

Apparently, this is the first time they have encountered this installation in 15 years. The added complexity drove up the cost, but that's only fair. Also, after they removed the staples, they remounted the screens with screws, so the next time they can be removed and replaced easily. We got an upgrade. Other things of note - they were both very professional and friendly and they left the job site cleaner than when they arrived. Great job!!
