    This is how my patio was left after being done.

    When installing my patio the removal was tragic and they left a mess . After calling numerous times, I got a text saying " we will put wood putty ( with the wholes being more then 4 inches. Doesn't seem like they put much effort into satisfying their customers.

    the dirt and rock  pile Jaime wanted to leave.

    So mixed review here. I've been sitting on this review for a while because I want it to be the most honest of our experience. If I could go back in time...I probably would have chosen a different company. We received our quote from Todd who was great. Such a nice guy and so reassuring of the whole project. He gave us advice on what patio to get--insulated vs non-insulated, whether we wanted can lights, fans, a TV mount. He also said they did cement work--so we were sold. I mean, all of the work done at once...great. So we thought... We had a total of three measurements for the project: Todd--the initial quote, Kayla--who spent about 5 mins only confirming the size of the patio cover, and Jaime--who measured only the cement area. I had questions regarding the cement with Kayla and she said "the cement guy will be the one to talk to." So...I directed questions and concerns to Jaime. First meet with Jaime seemed fine--"yeah we got it, no problem. I'll talk care of it..." but in retrospect, he didn't seem to listen to my concerns and questions or really come up with a plan to explain to me. I assumed he was professional and has done this several times--okay, great. We were worried about water run off going towards the house ... he said he would make it slope away from the house, granted the existing dirt was sloped towards the house. No discussion of any recommendation of drains for the new concrete. Jaime's crew came to level the area and created a HUGE pile of dirt that he had left on a different part of our backyard with NO INTENTION to remove. He was basically saying he could take it away but we'd have to pay? WHAT...? He said it wasn't part of the job...and that's when I learned he was contracted. He was making it a side job that he would remove the dirt and rocks. He became angry with me...and said I needed to talk to Kayla. I told him it sounded like an issue that he needed to clear with Kayla as well. Couldn't get a hold of Kayla, so I called Todd. Todd said it was not the case and the dirt should be removed...he said he would reach out to the Owner and Kayla. I received a texted from Kayla saying she was out of town but the dirt and rocks would be removed. SO....Jaime and his crew came and removed the dirt and rocks but not before spreading it around the whole backyard--in our planters and unfinished area which we had already cleared and leveled for grass. At that point I was so discouraged speaking with Jaime. Then a few days later he came with his crew to put in the cement. Okay, great. Done. Then Daniel, the patio installer, came and was fantastic. He also made a comment as to why the concrete was sloped too much...but he would make it look good and work with it all. He also mentioned the measurements were not correct and adjustments would need to be made. All in all the patio cover itself is great. LOVED Daniel...he does great work. BUT, the CEMENT WORK IS TERRIBLE. The cement is smooth and great quality but the SLOPE of the concrete is unreal. It's sloped far too much and water is pooling where the joints meet. We can't even put tables out or patio furniture without it being wobbly or slanted. It's awful. We had a few landscaping contractors come out for the rest of our backyard and ALL have said something about how poorly the cement was done. So discouraging to actually hear aloud what I was concerned about already. I reached out to Kayla for a solution...asking if anyone else can look at it and see if there is any remedy. Asked for someone besides Jaime since our encounter was rough. But she said he was the cement guy so yeahhhh. Anyway, the solution they gave me was to add a joint extension...it wouldn't solve the problem that the cement is sloped so much, but might help the water pooling. At this point, I just don't even think it's worth the trouble to have another encounter with Jaime. The only positive things I can say: Todd is a great salesman, Daniel is so hardworking and did an excellent job installing the patio cover with all the uneven cement and wrong measurements, and they completed the project very quickly. Other than that...nope, that's all.

    Look at this mess
    Lorraine C.

    I'm giving the company 1 star thanks to Kayla. They started last week & they were short on the cover due to Kayla's measurements. Now everything is just sitting there waiting to get all parts. They refuse to pick up this mess and now I have wait till they come back. Communication is horrible. No one knows anything. Feel bad for the workers they have to deal with her. I'll keep you'll posted

    Leaks
    Benji D.

    So if you read the reviews you'll see similar stories. As someone who is in construction, I will break down how this company works. 1. If you get a patio, it is subcontracted out. This is why "their crew couldn't make it today" is a popular Kayla response. 2. This goes with their concrete. Same thing. I only know because their concrete dude told me and hit me up for side work 3. They respond to calls but don't call back. I have a ton of leaks in my patio, they never called back after I sent pictures and emails. For all of you who don't know, you don't have to sue them. There is a better way. Just contact the California Contractors State License Board and submit your complaint. The board will do an investigation and likely take away their contractors license. Hit them where it hurts . If we all file complaints - that should send a nice message. Update: Doug the owner left a message saying to send an email to Kayla. I DID! 5 MONTHS AGO AND I NEVER RECEIVED A RESPONSE. IN FACT, I SENT THESE VERY SAME PICTURES!! I am sure Kayla will give one of her excuses from a list of her greatest hits. Like "oh I was out of the country" or "I didn't receive the email" or "we didn't have anyone to do it at the time." You know - the typical boiler plate Kayla messages. And this Doug dude just defends her incompetence. I wonder how much of his time is in court and then how much he actually gets to work

    Within 2 months there are several cracks in the NEW CEMENT. Poor customer service, poor craftsmanship.

    Dirt blown in from my skylight that was installed incorrectly.

    The absolute worst company. They don't communicate with either the customer or each other. No one in the company knew what was going on from start to finish with my projects. Now months later with the current winds it is clear they didn't put my skylight in correctly since freezing cold air and dirt is flying into my house. AND not shocking at all but NO ONE is returning my calls. Save yourself thousands of dollars and use a different company.

    Patio cover , insulated
    Lindsey H.

    I had a patio cover put in and I was very pleased with the outcome. Brandon was very professional and communicated so well from the very first appointment I had with him. The payment breakdown was clear. He even helped me pick the right colors. I love the way my backyard looks with the patio cover. Come install day, everything went smooth and they were done within one day. Highly recommend this company. They have a great price and a great product that I know will last me forever.

    Before Pergola installation

    My Pergola is nice, the material is sturdy, and well put together. I love the style and color. Matches my exterior color. The techs that installed were professional, personable, knowledgeable and quick. Not to mention, punctual. It took only a couple of hours. They cleaned up the area after they were finished; very pleased. Would recommend. Cheryl is the sweetest person, very communicative and always available to assist. I have enclosed before and after.

The temperature in the south facing bedroom on a hot 90 degree plus day would always be nine degrees hotter than the rest of the house. I decided to replace not only the four windows in the south facing bedroom, but six other windows that can be viewed in the same field of vision from the street, to keep the aesthetics consistent. The replacement windows I selected are double pane argon gas filled to help keep the heat out during the summer season. I put out a bid on Yelp and narrowed the field down to two companies, Note I did not select the least expensive bid, but actually selected the most expensive bid. My reasoning was a solid five star Yelp rating, BBB A+++ rating and the knowledge and excellent follow up provided by the salesperson, David White. Other factors in my decision were silver coating on the glass to reduce the intense green hue that most argon gas filled windows exhibit and exterior window casings that are solid without decorative ribs that would collect dirt. I was provided with a detailed explanation of the process and same day estimate. The process from start to finish took five weeks. This would have been as little as two weeks if I did not have an arch top window. Curved windows take longer to build, at least for Ameristar. It took me a while to prepare the two rooms, so I was not in a big hurry. The installation was done yesterday. The crew was on time, polite, and from my view, was extremely careful and exhibited excellent attention to detail. The 10 windows were installed in one day. The crew cleaned up their mess very well and everything went according to plan. I am completely satisfied with the entire process. The windows are very elegant looking, not so green and make the house look better. I trust that the temperature in the south facing bedroom will level out with the rest of the house with the argon gas in the windows. Five stars all the way. Well done.

They have a physical store in norco which was being run by Andres' wife. After 3 weeks or so give or take... i got a message that they were ready to install. Well within the time frame.... They informed me when they were on the way. They probably took roughly 2.5 hours. Lucas, Andres' son was present. Nothing was rushed and i saw how they handled everything... They can reuse your old door handle... but in my case, i bought a new one... just because. The price: It's pretty fair. It isn't cheap but you get what you paid for. For the peace of mind... ill do it again. Since i got a door replacement, everything was included. From removing the old one , to clean up, trash, installing... and thankfully.... the door i got doesn't need any paint. So it's pretty good. Threshold was top notch. And it seems water / insects wont be able to pop in. Will i choose to work with them again? Probably yes... Once i opt for a screen door... maybe in a couple more months once it gets a little bit cooler.

She arrived with a sample retrofit window, answered all of our questions, clearly explained the process, and provided a fair, no-pressure quote that was fully in line with and/or better than other quotes we received. We especially appreciated that this is a small, family owned, business, and that in addition to being an owner and primary point of contact, Maribel shared that she also had an active contractors license. Once we decided to move forward with Silver Lining, everything happened exactly as promised (and incredibly fast, which was also important to us, given availability on summer break). Exact measurements were taken promptly, the retrofit windows were custom ordered, and the installation team replaced all six windows in a single day. The communication, professionalism, payment process, and quality of work of all team members were A+ throughout the entire process.
