What stood out most was their attention to detail. They came out a couple of times before the install just to double-check and confirm all the measurements, which gave me a lot of confidence that everything would fit perfectly--and it did. The installation itself was clean and professional, and they made sure everything was sealed and finished properly. Communication was easy, and they were responsive whenever I had questions. Overall, I'd definitely recommend them if you're looking for reliable, detail-oriented window replacement work. I'd use them again for future projects.

We hired Smart Window Company to fix and ultimately replace a sliding glass door that had become a…read moreconstant problem. The door was hard to slide, didn't seal properly, and clearly needed more than a quick repair. From the first visit, the team was straightforward and honest about what could be fixed versus what made more sense to replace. No pressure, no upsells. Scheduling was easy, they showed up on time, they worked clean and efficiently. The install itself went smoothly, and the difference was immediate. The new sliding door glides effortlessly, seals tight, and feels solid. No rattling, sticking, or gaps. Communication was great the whole time: they explained the issue clearly, walked through the replacement options, and followed through exactly as promised. If you're dealing with a sliding door that's past its prime and want it handled right the first time, this is a company you can trust.

Summary: This company does truly care about customer satisfaction. As David and Tom told me after…read morethings went awry: "We don't always get it perfect, but when we don't we try hard to make it right." I reached out to start the quote process a little before Thanksgiving and was quickly responded to. I scheduled a Zoom-based overview of the materials and services offered with David, as well as provided some information about my property and the windows that I thought I'd need to have replaced. The next step involved David visiting my home to measure each of the windows and assess their surroundings when putting together an estimate. He even brought a floor model window for me to test the ease of sliding it open and closed (it was very easy). Next, he provided me a quote for the six windows we had identified replacing, which included a Black Friday discount. The total was around $5k for materials and labor. I ended up swapping one window for another and he quickly updated the estimate for me. No pressure or need for down payment. After consulting with my wife, we agreed to move forward and the next step was for a technician to come and measure the windows to a quarter inch so that the dimensions would be sent off to the SoCal manufacturer and the windows constructed over the next 2-4 weeks. The technician also assessed the surrounding area of each window and told me what would need to be cleared to make space for the installation. Soon we got a call that the windows were built and ready to install. We were scheduled for first thing on Saturday, Dec 27, and were told that it would take most of the day but all of the work would be completed in the one day. On Saturday morning, Frank the installer arrived with another installer and got to work. We had moved lots of items away from the windows as needed, and throughout the day we saw the technicians as they would traverse the stairs and through the front door with materials, occasionally saying "hi" and just checking on how things were going. Later in the afternoon, Frank called me up for a walkthrough and then informed me he had two major problems: 1. All six windows measured were such that they required spacers around them to fill gaps that were visible on the inside. For some reason, they were not ordered initially. 2. Only five of the windows had been sealed from the outside because one window had a tree encroaching on it and they couldn't get a ladder up to seal it. Neither of the two visits had noted that. Tom was called and apprised of the situation at the end of the walkthrough, and with a new storm a few days away and one window not sealed, I went into panic mode. I emailed a full recounting of the situation to David, and began hunting for a tree trimmer to come ASAP so that the window could at least be sealed or the old window reinstalled before the rains. The next day, Tom called me and told me they were ordering the spacers and would have them by Monday, and that Frank could come and trim the tree so that I wouldn't have to pay for a separate trimmer. We ended up scheduling for Tuesday, and Frank showed up solo to finish the job. He trimmed the tree and disposed of the materials, added the spacers and sealed everything remaining. When all was said and done, we were happy with the windows and the way the company worked to make it right (and on a tight schedule). We did have to keep everything in its temporary locations for another few days, and we did have to get vocal about our frustrations, but Smart Window Company finished the job and called to check in on us after to make sure everything was good. The next storm hit and we haven't had any issues yet. The product is solid, and the company cares where it matters.

I came in hoping to replace both my…read morebedroom windows and the sliding door in my living room, and from the very first interaction, I was met with nothing but warmth, honesty, patience, and professionalism. Nan was the one who initially educated me in the office, and she was absolutely incredible. She took the time to walk me through everything, answered all my questions with so much clarity and patience, and genuinely wanted me to understand what would -- and would not -- solve the issue I was experiencing. Her knowledge and care made me feel respected, informed, and never pressured. What completely blew me away was the honesty. Despite being more than capable of selling me new windows, they were the only shop that told me the truth: the change I was hoping for couldn't actually be achieved through window replacement alone. That kind of integrity is rare and speaks volumes about this company's values. Then there's Roy -- one of the owners -- who personally made the journey out to my home to further educate me. The fact that an owner would take the time to come out himself, explain everything in person, and make sure I fully understood my options is something you just don't see anymore. He was thoughtful, thorough, and incredibly generous with his time. And yes, fair warning -- Roy looks like he walked straight out of a magazine. Be prepared to be completely stunned by the presence of an actual god while receiving some of the most honest, professional guidance you'll ever get about windows. Even though they didn't make a sale this time, Lion has earned a customer for life. I will absolutely return for all my future window needs and recommend them to friends and family without hesitation. Please don't ever change, Lion. Whatever you're doing is working beautifully. Everyone was so kind, genuine, and knowledgeable. Huge gratitude to Nan for her education and patience, and to Roy for going above and beyond by coming to my home. I can't recommend this company enough and wish them nothing but continued success.
