    We were so happy with our new windows. We have already noticed a reduction in outside noise and a savings to our energy bill by not having to run our AC as much. Our sales representative, Cody, went above and beyond by working on his birthday and ensuring that we got exactly what we wanted. The window installing crew led by Boris was very courteous and professional. Boris did a walkthrough with me with every window that they installed. I am impressed with Alpha EnviroTech and will look to them the next time we have a major project. Great work!

    I LOVE my new windows! A few of my old windows were starting to leak in heavy rain, so I decided to replace them with Alpha. Their sales person, David, came by to show me their product. He was great - explained everything and demonstrated how the windows they install block sunlight to significantly reduce heat in your home. I live in Southern CA so this is huge! I've already noticed a difference in indoor temperature on sunny days, it's much more comfortable during late afternoons when the sun used to heat up my family room and make it stuffy. I expect my electricity bill will go down this summer as a result as well. The double pain windows also reduce noise, and they are a breeze to open inward to clean. Installation was super fast! I had every window in my house replaced (19 total) and the team - led by David (a different David) and Marco - did it in 2.5 days. And they did a great job!! It was noisy, no doubt, but the team was friendly, courteous, and very respectful of my home & property. They cleaned up at the end of each day and made sure any trash was hauled away. My windows look so good! I was hesitant to do this because it's a big project and expense, but it was so worth it! The windows Alpha uses are specifically designed for CA weather, are reasonably priced, measured to fit your windows, and as mentioned above reduce the amount of sunlight blasting into your home in addition to reducing noise. I love them!! Thank you, Alpha - you did an amazing job!!

    I just had my house painted in Sacramento, CA. I think the business is expanding. I love my paint job. They did an amazing job. They also repaired stucco and dry rot areas of my trim. The guys were very easy to work with. Now in the beginning when they were trying to sell me the paint job and going over all the qualities this paint has I thought they were just putting on a show but since I've had my house painted my air conditioner gets the house sooooo cold! This paint is supposed to help insulate, be a moister blocker and fire repellent. The difference from before the house was painted is out of this world. My air conditioner would have to run all day to get this cold, now it's freezing in an hour. Plus it looks so nice . I've fallen back in love with my home. Next project: fix my yard up!

The pricing was very fair and competitive, which made the decision even easier. Mike, the owner, was honest, transparent, and extremely helpful every step of the way. He took the time to answer all my questions and made sure I felt comfortable with everything. The installers, Willy and J.C., were professional, polite, and very respectful of my home.

We met with Mike (the owner) at his showroom who went through every option and provided clear details for the products we had to choose as well as the process from start to finish. We went with Mike's product recommdation, Anlin Windows, based on those details which was clearly the right choice. Mitch (the ops manager/job forman) came to our home at the appointed time, took the measurements and advised what we needed to do to assist in the installation process which was basically moving any large objects away from the windows, both inside and out. In fact, we were contacted every step of the way from the owners, office staff and field staff and advised of the progress of our order. We were notified of the windows arrival at thier warehouse 6 weeks later and set up an installation date. JC and Willy arrived on time and got started right away after thanking me for clearing thier work areas as thoroughly as I did after the intial walk through. They did an amazing job. They were courteous, clean, respectul, and completely professional in every way. They had every window plus a very large slider installed before the end of the day and once again complimented and thanked me making their work areas accessible and easy to work in. They also left every area they worked in cleaned up as if they were never there. A rarety these days! JC then provided me with some tips specfic to any potential screen door squeeks and advised me to apply something on the screen to prevent any accicdents in the form of me or anyone else walking through that screen. I used a couple of thin strips of duct tape. The windows/screens are obviously new and almost transparent. Especially after living with the previous extruded metal OG windows for as long as we did. He showed me the features of each window and door, explained how the locks worked on each and answered any questions I had. There was minor 1 hiccup. During the unpacking process of the windows, JC pointed out to me that 1 of windows would not be able to be installed as it arrived broken. Not the window itself but the top right corner of the exterior vinyl overlap. The damage was not seen at the warehouse as it was under the protective card board/plastic and must have happened during the shipping process from the factory. I know from experience these things happen and it is how they are reacted to that seperates the good companies from the bad. OCWE took care of it without hesitation and insisted I deduct $500 from the intial installation balance until the replacment was installed and the job completely finished. The replacement was rush ordered. I was told it would take 2 weeks to get it. I got a call extactly 2 weeks later and we set up the installation appointment. The final window was just installed in under 30 minutes by JC and Willy as I had requested they come back for the aformentioned reasons. My wife and I could not be more pleased and satisfied with the choices we made specific to the company, product, pricing and professionalism of every team, top down from sales, ops and installation. We would do it again in a heartbeat! I highly recommend OCWE for window/slider upgrades in every way and when you do, make sure you specifically request JC and Willy to install them. You will not be sorry!

    Fabulous Window Replacements!…read more We recently undertook a major project to replace more than 40 windows in our home. During our selection process, we considered both glass replacement and full retrofit options. After consulting on each and weighing the pros and cons, we ultimately chose to move forward with new retrofit windows. We received three estimates from three different window professionals, and we decided to sign with Legendary CALREP. One vendor came in at nearly triple the cost of the others, but between the two competitive bids, Legendary stood out--not just in pricing, but in the confidence they inspired regarding delivery and installation. Having recently finished installing wainscoting throughout our first floor, avoiding any damage was absolutely critical. Scott Lutz supported us from the very beginning, taking time to understand our priorities, answering all our questions, handling measurements, and providing prompt, professional communication at every step. He was the only representative out of the three vendors who consistently followed up without us needing to reach out--something we greatly appreciated. Our installation this past week was completed by Art, Carlos, and Junior--the dream team! They were communicative, punctual, friendly, and highly professional. Each day they left our home spotless after a meticulous cleanup. We were amazed by how smooth the installation was--and thrilled that our wainscoting remained completely untouched. The windows are beautiful! From the initial meeting to the final walkthrough, we've been incredibly impressed and appreciative of the entire Legendary CALREP team. We highly recommend them--they are honest, competitive, communicative, and genuinely take pride in exceeding expectations.

    We had all of the windows in our home replaced by Legendary Cal-Rep Windows in 2020, and…read moreunfortunately, our experience has been incredibly frustrating ever since. Shortly after installation, we discovered that the large staircase window leaked whenever it rained. Over the past five years, their "fix" was repeatedly applying messy exterior silicone that looked terrible and never solved the issue. At one point, they even suggested the leak might be caused by something within our home rather than the window itself. Eventually, they replaced the window and discovered the original installation they had ordered the wrong size window and had tried to just fill the gaps in and make it work. The second replacement was faulty, requiring yet another order and installation. Now, in 2026, the newest window was installed but still does not function. A Milgard representative inspected it and confirmed the issue is due to improper installation. Despite all of this, we still have no resolution, and there has been little to no proactive effort from the company to make things right. We are extremely disappointed with the product, installation, and overall service. Messages are ignored or we are told they are "checking on the status" but we never hear back. I will update this review if we EVER receive a proper resolution! I am in the customer service business myself, so to have a company treat you this way is so very disappointing.

I made an appointment, and they completely stood me up. Later, they claimed they tried to call me or left a voicemail to change the appointment, which is not true. They never called or left any message. I have documentation as evidence, but I chose not to continue the conversation because Max kept defending himself and arguing instead of trying to resolve the issue. They also had my mailing address incorrect. I spoke with Max the day before my appointment to correct it, yet there were still multiple errors. Overall, the business seems very unorganized. The receptionist told me Max was in the office, so I was surprised when Max later claimed my appointment was with a different representative. This inconsistency felt very unprofessional and questionable. I took time out of my day for this appointment, and it is extremely rude and unprofessional that they never showed up. I do not recommend doing business with this company. There are many other businesses that provide much better customer service.

Within five months of the installation, I noticed the trim they installed on the inside along one of the two new windows had come almost entirely undone, to the point that there were huge openings and I could see the insulation foam they used in the gaps. I even had a bee somehow get through into the room thanks to the poor installation. For the amount paid, I was frustrated to realize they hadn't done a better job. Next time I'm in need of new windows etc., I'll be sure to look elsewhere. Update: There also appears to be gaps along the top exterior side of the other window - I heard some kind of large insect (we get alot of bees and wasps around my building) buzzing and trying to escape from inside there. Luckily the interior trim remained sealed on this window at least. But once again, I find myself disappointed with the installation.

All other windows in the house had been replaced previously, and most companies had a minimum order quantity that didn't make sense for our project, or had long lead times that would have been problematic for the timeline of our project. The sales rep Tim was on time to his appointment, quickly assessed and measured the window, and got the process started. He was readily available for updates, and the window was available very quickly! The install was done well and matches the other windows in our house. We are VERY happy with Cal Replacement windows and will definitely use them again in the future for any other windows we might need.
