I had a great experience with my window installation, but now that I've been trying to follow up to get a small repair done, it's been crickets. Nobody's been answering my emails or texts, and I've basically been ghosted. Very frustrating. read more

We previously had a great experience with WW. However, we needed a window replaced that WW had ordered/installed (still under warranty). The same person who previously came to help us came to take measurements of the window so they could order a replacement. They came by & we never heard from them again. They warned us the replacement could take a few months. A year later (ish), we reached out. They said they need to come by again & get the label from the window. We offered a good time (10 a.m. or later on date x). Now again not responding. I would never use this company again & do not recommrnd them. This unnecessary stress is ridiculous. I'm going to talk to my cc company to see what can be done. I'll also be contacting BBB, etc when I have the wherewithal. Luckily, my husband doesn't delete emails, so I have all my documentation. read more

Estimate was higher than another I received. They also greatly discourage getting a building permit. They told me they if they needed to break the stucco, they would not repair. Overall, seemed like they wouldn't do a complete job with window replacements. They also didn't offer what the warranty was on the windows or workmanship. read more

WW was responsive right off the bat and flexible on scheduling. Their prices were very reasonable and they worked to find the right windows for our project (ten window replacement for old wood frame windows). When one of the screens was damaged, they had no qualms replacing it. We would recommend them and use them for our next project. read more

Simple job to seal a window sill due to seepage coming from the rain season earlier this year. Everything started out great. Alex was very professional and gave the most thorough assessment and affordable price.  However, everything went south after. We rescheduled multiple times and every time it fell through because of some incident on their end. Whether it's true or not, 3-4 no shows is absolutely unacceptable. He has been extremely inconsistent via phone and eventually went radio silent. read more

Excellent service! Honest and well run company that truly puts its customers first. We were referred to them by a neighbor. Installing windows is expensive and a huge investment but well worth it. It can be overwhelming finding the right company. Alex and his team made the process so smooth and easy. They went above and beyond and even did some extra work that we didn't expect. He was transparent about timelines and process. He didn't try to upsell and worked with us to find what we needed to replace all the windows in our single story 100 year old home. Absolute pleasure to work with. We highly recommend and would gladly work with them again. Also it's a family run business that is rooted in Oakland. 10/10! read more

We partnered with Alex to help replace several original windows in our old Colonial home. Alex inspected and helped us determine what windows to focus on given we couldn't replace them all. He was honest, knowledgeable and rapid with our bid. We ordered Marvin windows and did have to wait for them to be custom made which we learned was standard. When they were ready, Alex and his team installed them rapidly and without any hiccups. We have since ordered two more windows from Alex and they are all beautiful and working well. We highly recommend him and his services. read more

Update 11/20 : Just received a certified letter declaring preliminary notice from Ashby Lumber that Alex has not paid $30k worth of goods due to Ashby Lumber. Avoid at all costs! After we paid the 50% deposit, Alex confirmed the windows for our home would be ready in mid-July. Come July then August, through early September he had one delay and excuse after another why the install needed to be pushed back. Long story short, two months passed where I had to hound him to complete the job - it was a nightmare. I would not recommend this business. read more

I received a very good bid from Alex in October '23 and gave him the deposit in November. For the next 11 months he scheduled installation 6 different times, only to postpone them (on the date he promised installation) due to what he said were problems with the manufacturer. After 11 months he finally decided to cancel the installation and I found out that he HAD NEVER ORDERED THE WINDOWS! Why he scheduled installation for windows he never had is beyond me. I had to threaten to report him to the City and State before his father, Bernardo, the owner of Winning Windows showed up with a check returning my deposit and an apology. Bernardo may be ok to work with (I don't know), but if Alex is involved, stay away. And Bernardo should have intervened much sooner - I had met him earlier when Alex cancelled an installation. read more

We love our new Marvin Ultimate windows, and we're very glad we went with Winning Windows. They're a small company that takes care of its customers and also has the best prices. We had a lot of choices (colors, wood, etc), and Carol, the owner, provided great advice. The installation process was a good experience. Bernardo Perez is a general contractor and has partnered with Winning Windows for decades. He's extremely knowledgeable and skillful. Our house is 85-years-old and set on a hill. There were challenges because our window openings aren't square, due to shifting. Bernardo and his crew took the time to do a careful, thorough job. It took us a couple years to figure out which windows we wanted; then manufacturing took a few more months. But thanks to Winning Windows it was all worth it. read more

We had our back French doors replaced. Our old doors were leaking water into the house. The team did an assessment on the issue and gave some clear options to resolve the issue. In the end, we decided to replace the doors. We got a good range of options at a very fair price. I will definitely work with them again! Highly recommend! read more

Fantastic service in the age of Covid. Replaced all my downstairs windows in one day and swapped out my front security gate with a beautiful and stylish new one. Very hygienic team using precautions and masks. The owner herself came out to inspect the project once finished. I loved the fact that I supported a female owned business. I am a very happy customer. read more

I cannot recommend Alex from Winning Windows highly enough - I saw some water damage on the window sill, panicked that we may have mold problems behind the wall, and called a bunch of window companies. Most of them told me that they have 4 window or $4k minimums, they can't come out for 4-6 weeks etc. Alex made time today to come out and look at it, took out the window sill and drywall immediately, and figured out where we had a water leak. He'll be replacing the window when it arrives, and if we ever need more windows work we'll be calling Alex in the future. read more

Small business with great service. They answered all my questions and helped as needed. Outcome was just what I needed

Recommended by Mix in Montclair who did our custom window coverings (Mix is great!). Cody came out in late December/early January to quote us for a 10 window replacement. Was on time, knowledgeable and got us a quote quickly with both casement and double hung options. We had other companies come in and quote us after and though some were a little lower, we ultimately decided to go with Winning Windows based on the reviews and our interactions with Cody. Upon reaching out to confirm the quote and give Winning Windows our business (note we did not receive any follow up whatsoever since we received the quote), we were informed the quote was no longer valid since the price of the Marvin Integrity Ultrex Windows was increasing 5% in 2 days and they could not come out for the exact measurements to make the order under the old pricing unless we could be home in the next 2-3 hours (we could not as we are both working professionals). They could not accommodate another time because they were very busy doing measurements for the customers they managed to tell about the deadline and price increase. After talking to folks at window showrooms in Berkeley, it turns out the annual price increase timing is known well in advance though the exact increase is not. We were never told about the increase, the deadline, or a drop dead date for the quote (all other quotes explicitly stated they were good for 60, 90 and even 120 days). Being told would have accelerated our decision and not left us sour on this company and left with our second choice for installers. Not happy and they lost our business forever. read more

We chose Winning Windows to replace 9 windows and add a sliding door to our house, and we're thrilled with the results. There is now much less street noise inside, and we're actually sleeping better. Alex and his crew were great to work with. They were mindful of our elderly cat and worked around her to keep her inside and safe. The sliding doors really transform our little 965 square foot house, making it seem so much bigger! Alex also went above and beyond to recreate the existing trim. We definitely recommend Winning Windows. A great job at a fair price. read more

We had a great experience with Alex and the crew from Winning Windows. We love our new windows and French doors. Alex was easy to contact and followed up quickly. They cleaned up after each day of installation and left our house in good shape. I recommend them highly. read more

Alex and his crew provided exceptional service. Alex understood older homes that had shifting foundations that required adjusting the measurements to securely fit the window. All the windows gave the home a fresh look and they did their best to work with our timeline and budget. It was great to see them take care of the home and cleaned the area before leaving the property. Highly recommend Winning Windows! Thank you Alex for giving us a great experience. read more

Amazing communication and very professional. Every step was done in a timely matter and Alex was very easy to communicate with. Turn around time on quote was exactly what I was told. I'm very happy with them and can't wait till my windows are installed. I highly recommend Winning Windows. read more

I needed two second floor windows that required a time-consuming effort to remove and replace with the added need to patch stucco on all sides. Alex and his crew were very professional and always punctual. This is a rental where arrangements with the tenant required some polite discussion and care. Alex did it all. I highly recommend them. (Price was fair as well!) read more

My decision to work with Winning Windows was 100% based on their reviews. I had windows in two homes replaced with Marvin Clad and Windsor. Now that it's all said and done, I know Carol, Cody and the install team are very easy to get along with and will do what it takes to make the customer happy. I'm writing to give those who are thinking of new windows some general considerations. For our residence, we bought Marvin clad casements with retractable screens and replaced all the windows. We chose not to have the retractable screen on four windows to save on cost and really wish we had just gone all the way because now we don't use those four windows. I highly recommend casement push out windows. My husband and I both didn't want to have to crank a window to open and close it and stayed true to the original with the push out. We can also turn the windows and clean both sides from inside our house! For our rental property, we bought Windsor casements, black on the outside and white on the inside (in case you didn't know that was an option like me). I replaced about half of the windows and if I felt like I could have afforded it, I would have replaced all of them for uniformity, comfort, increase in the value of the home, all that jazz. Carol and Cody are not pushy at all so you'll need to push yourself to do this if you know it's the right thing to do. For weeks and weeks before the install in our home, I looked at windows in homes as I drove by them and realized most homes do not have updated windows. Again, if you can replace them all, do it. In our rental property, for example, I did not replace the two windows in the laundry room but if I had, I'm sure the windows would be a new tool. It's the room with the cat box and heat from the dyer so it makes sense to use the windows in there. When you have old or hard to use windows, you tend to avoid using them or use them minimally and it takes away from the potential of the home and personal comfort. New windows can make the window space seem much larger than it did with the old window too. Surprisingly so. One last thing to consider is how noticeably quiet your home will be with Marvin clad. I can's speak for the others. We live on a busy street and it is so quiet now and a pleasure we will never take for granted. Our bedroom faces the street and I don't even hear the garbage truck. read more

Carol responds to support questions 10+ years after installation. Now that is what is call... dedication to her product and services! Upgrading my review from 4 stars to 5 stars. Thanks Carol! read more

I cannot recommend this business. We placed a very expensive order for multiple windows for our home, then didn't hear back for months and ultimately had to email Winning several times to find out the status of our windows. Then, when the windows were installed, one of the parts was missing. Winning told us they would follow up. Six months later, they still have not. When I contacted them to ask (again), they told me that I should call the vendor directly. There is no sense in hiring this company to be told that you need to wait in the long phone lines to manage their vendors for them. read more

Alex and Bernardo are fine craftsmen and the windows they installed for my home look excellent. Even the building inspector was impressed by the windows and the quality of the installation. Alex provided superb customer service beyond my expectations. I wish Winning Windows many more years of success. read more

Carol and the Winning Windows crew were amazing! Reasonably priced and consistent follow-through from quote to installation. The crew (Alex and Alfredo) were so professional, incredibly clean, and very efficient with their time during installation. We had five windows replaced and they were done in little over half a day. Carol came at the end of the job just to make sure we were satisfied. I highly recommend them to anybody looking for new windows. If we need more windows replaced we will definitely be calling them up again. read more

Winning Windows installed all new windows in my house just over a month ago. The process was so painless. The owner, Carol, is a delight to work with. She is smart, direct, clear, and helped me consider all my options for each and every window. This took several conversations after the initial visit, so we were both sure I was getting what I wanted, with both safety and aesthetics in consideration. Her install crew was polite, focused and easy to work with. They cleaned up after themselves and caused the least amount of havoc I could have imagined. While I did call with a few things that I felt still needed work to be complete, Carol and her team responded immediately and came back to take care of the issues outstanding. Since most construction jobs can take a second pass, I wasn't bothered by that at all. And they responded well to my requests. I truly could not be happier. My house, near San Pablo Avenue, is so much quieter, and we are already using our heat much less, with the house keeping the heat in well. Love Winning Windows! read more

I just called them and they are booked out until December and she said that the "normally" do anything less than six (6) windows... oh well

1. Carol could not be any sweeter. True story. 2. Windows are an investment - but they're kind of like buying functional work shoes - not super exciting. And I can't afford remorse, they HAVE to be good. 3. Bernardo and his installment team were super professional, they worked fast (but not TOO fast), brought their own lunch (which I found inexplicably comforting) and they stayed till the job was done, perfectly. 4. Cents showed up in my final bill, which made me feel like Carol wasn't rounding up. The only reason I couldn't give Carol five stars is although it might be more expensive, being able to pay by plastic, vs. check would have been more convenient. read more

While researching window replacements for my house, it became very apparently that the quality of installation matters at least as much as the quality of the windows. I got a few quotes and settled with winning windows because their prices were competitive and the installer got good reviews. I am very glad I went with them. The installers were very professional and clean. On the first day of install they found water damage on the wood frame around one of the old sliding doors. They called me about it and replaced the wood and installed a z frame to prevent water from leaking in again. It took them all afternoon to do it when they didn't have to. I have heard of a lot of horror stories about other installers just installing windows over rotten wood without saying anything. Needless to say I am very glad I went to Carol and winning windows. The windows themselves aren't anything fancy. But like I said, installation is important and they did a great job. I can tell a huge difference in temperature. Go with Carol if you are looking to replace windows. read more

Carol and her team are a dream with which to work. They kept scheduled appointments, give fair/competitive quotes and completed the job on time. Carol gave me excellent recommendations and I could not be more pleased. I had three windows and a door replaced. They also trimmed them all out. The work turned out beautifully. The changes transformed the space, so now I have TONS of natural light in my art studio, with no bugs! The work crew kept the space clean and were great to work with as well. They kept to the schedule and completed the work as projected. I would highly recommend Winning Windows. read more

Updating this to address the comment from the business: To my knowledge I did not yell. I most certainly did not swear. After I asked how I was supposed to get an estimate for all the windows to see if I could afford it and she answered "we only do 6 windows or more.." for the 4th or 5th time, I said "Ok, I get it. You don't want my business. Thanks!" And hung up. No swearing. No yelling. But I guess they need to somehow turn their lack of service into the fault of the potential customer in an effort to save some face on the review. Oh well. Lesson learned. Don't give an honest Yelp review because the business will make something up to try and blame the reviewer. I can't speak to the quality or workmanship, as I couldn't even get an estimate. Called Winning Windows based on the good Yelp reviews, many of which note they had a couple or a few windows done. Though I want to get all the windows in my home replaced, I have no idea what it will cost, so I figured I'd start by getting an estimate on all my bedroom windows (4). My call was answered by "Grace." Grace was polite and friendly, but after a few minutes, she informed me that they currently have a team of 4 window installers, and therefore they are only accepting orders for 6 windows or more. Huh? According to Grace, all installers on the team go to every job, and because it's not cost effective for them to install less than 6 windows when they have 4 people, they won't do anything less. I mentioned that there were Yelp reviews from people who said they had a couple or a few new windows installed, and Grace launched into this explanation about how, depending on the time of year, they sometimes have fewer installers, and when that happens, they'll do a job with fewer windows. Several times she repeated that they are only doing installs of 6 or more. I told her (again), that I was interested in having all my windows replaced depending on cost, but that without an estimate I had no idea whether I could afford it. Her response? You guessed it! "We are only doing jobs with 6 windows or more." So apparently they don't even want to make the effort to find out if I can/will do the entire house. No, that's too much for them. After all the wonderful reviews I have to assume it's gone to their heads and they have decided customer service is no longer necessary. Definitely will not be looking to them to replace the 14 large windows in my home. read more

We only went as far as a quote with Winning Windows, but we wanted to write a review because of their excellent customer service and professionalism. We worked with Cody who was in constant communication with us to give us a quote for our window replacement. He was onsite within a few days. We received our quote promptly and he answered all of our questions with great detail and skill. While we decided to go with another quote due to budget restrictions, we appreciated his hard work and effort and wanted to make sure that was recognized. Thank you for helping us in our quote search process. read more

As part of a remodeling project we decided to replace the windows and patio door in our kitchen/family room. We had 4 company's out. We were shocked at the cost of this project. When we received the quote from Carol we thought she forgot something, like the windows. A really big part of our decision was when the other company's came thru our home they were sure to point out all the things they don't do and there was a lot of them. However when Carol walked thru there was no such thing as we don't do and she was like right. All is installed. The quality of the windows and patio door are great. Her team of installers were very nice and professional. When they were thru they cleaned everything! We didn't have to do anything. It was a painless experience. We will be back! Thank you Carol! read more

We had all of the original windows in our 1927 Tudor-style house replaced by Winning Windows this spring. The windows recreate the original casement style but with double-paned glass for heat efficiency. The windows also open so that we can have a breeze cool the house on really warm days. We secured 5 different bids for the windows, but Carol's was the most effective, in terms of cost, product (Marvin Windows), and installation; she even secured our building permit for us. Her crew completed the job efficiently - cleaning up the debris, sealing the window casings, and making sure that everything was done properly. A small glitch occurred when the wrong hardware for opening two of the windows was discovered, but those two windows were re-ordered and installed without further problems. In addition to the the casement windows, Carol found great screens for the double-hung windows on the side of our house that allow those windows to be open for air but are secure from any outside access. Very safe and easily opened in case of an inside fire emergency. It was a pleasure to do business with a local firm who stands behind their product and their work! read more

Called for a window replacement estimate and they told me how I could fix the problem without replacing the window. Thanks!
