I replaced 7 windows of various sizes, 6 of which were on the second floor. They replaced the 6 entirely from the inside, flawlessly, neatly, and all 7 windows in 6 hours, from arrival of ( 3, skilled) workers to final cleanup, inside and out (all debris and old windows taken) away, and all furniture back in place. Various window treatments were carefully removed, and replaced exactly. Their price was very reasonable for a high quality product and included everything from order through final cleanup. read more

They are aggressive to get your job but failed to come through as they promised... Disappointed and becare when working with this company. Becare every careful if you use this people, Anush reached out me several and get the job December 2025, they were great to start with but disappointed as soon the start of the work and did not follow through. 1) I had new floor put in, when their team came to remove and install the windows, they did not protect my floor, I stopped the work and layout the floor protection my self. 2) They did not seal the windows properly, 3 of my windows leaked huge amounts of water during the Dec 24, 2025 storm. They did come out to reseal few days later but we have yet to know if the work was up-to-par. They never offer to pay for the costs to repair the damage on the walls, window sills and flooring. 3) Anush was nice to inform me of the rebates, but twice the submission was rejected my Milgard due to a non matching sales code. I called, emailed and spoke to Anush. She said she would fix it, it never happened, it's been 5 months now. She has not returned any of my calls nor responded my emails. I have been asked by my neighbors to refer them, I will tell them what happended to me. read more

Arman snd his crew are amazing. He is very honest and always gives me great advice on which windows should be changed and which should not. I have now changed all 19 windows in my house. He and his team are very professional and proficient. I don't have to worry about a thing. It takes them less than a full day to change windows. I would recommend Arman to everyone who needs new windows read more

We recently worked with Nick from Greco Windows & Doors to replace all the windows in home. There were 13 total, so it was a big job. Nick came out for the initial visit & estimate and then the installers came out to do the official measurements. We were told it typically takes about 3 weeks to order the windows and have them delivered, but a few of the casement windows we needed were back ordered so it took about 9 weeks. This was a bit longer than we were anticipating but Nick's communication with us throughout the process was excellent. When install day did arrive, the team was very fast and professional! They make it look so easy. Unfortunately two of the windows that were delivered were the wrong size. We checked and the order was correct, but Millard had delivered the wrong sizes. Nick worked his magic and had the correct size windows within 2 weeks. His installs came out again and out in the last two windows. Their pricing is competitive, product is superior and communication was excellent. We would highly recommend working with Greco Windows & Doors. Our new windows have made such a different in our home! read more

I got a replacement sliding door for my condo and I gotta say, I was so happy with the price, professional speedy install and quality, I ended up replacing 4 of my windows. Then I ask Arman if they also do wardrobe doors and they said yes!! So I ended up replacing that too.I'm so happy with the results. What a great way to start a new year! Thanks Greco Windows & Doors.

Requested quote, Nick showed up in a mask and assessed the property. I had already received 4 quotes prior to his visit, so I had an idea of what the cost was. He was extremely professional and even offered his advice on some additional work I wanted to do with the windows. He said it would take two days for me to get an estimate. He didn't try to persuade me or push me into making a decision. He emailed his quote and requested that I contact him should I wish to proceed. He was by far the lowest quote I received. I was amazed and truly blessed to have such a professional and honest salesman give me a quote. The windows are beautifully installed, and he even came out to the site to ensure customer satisfaction. Thank you NICK!!! You are a Gem! keep up the good work!!!!!! read more

Was in search for a reputable company to order windows and doors from and after much research I came across Greco Windows. I called in and Anush did an amazing job answering all my questions. Windows were delivered on time and installed with no hiccups. Thanks again Greco. Definitely recommend them to anyone looking for quality windows and doors. read more

I must say this place was really great. Anush took care of us and was a pleasure to deal with thru the whole process. And the 2 young men who did the install did a fantastic job The Milgard windows we ordered (3) were a custom size so it take a month and a half for them to come in but we'll worth the wait. Very happy and I highly recommend this place. Thank you Greco!!! read more

I hired Greco for 2 sets of French doors. I had bid out to several companies and they were the most reasonable plus they had good reviews so I hired them. When the doors finally arrived, they were not the design we agreed on and getting new ones took months. When those finally arrived the install was so bad, they cracked the wall, they were unbalanced and couldn't lock. I had to constantly call Francisco who sometimes replied but most often didn't. When we finally got them working and I was somewhat satisfied we ended up with all that rain. The doors swelled so much I couldn't open. I called and texted repeatedly because I believe the wood wasn't treated. I even got the owner on the phone who said he would call me right back but never did so I ended up hiring someone to shave the doors so they would be operational. Would never recommend Greco. read more

Found on Yelp. They have a weird phone tree for "inside sales", "accounting", and several individuals by name. No way to get to an operator or to a secretary to direct calls. I pressed several numbers all of which took me to voicemail messages. Sent them an e-mail through their website on Friday June 3, 2022 at 1:45 PM asking them to call me since I can't figure out who to contact using their phone tree. Francisco called at 4 PM on Friday, June 3, 2022. We made an appointment for Wednesday, June 15 at 2:30 PM. Francisco did not show up nor did he call. I called him and texted him at 3 PM - 30 minutes after the appointment. He did not pick up or respond. I also called Greco Windows directly and asked where he was. At 3:10 PM, Francisco called and said he has been having car problems for a few days and doesn't have a vehicle. He stated that he did not forget the appointment - although he did not call me to inform of any of this until 40 minutes after the scheduled appointment time and only because I called him. Francisco said that he would talk to his foreman, Oscar, and send him instead in the next couple of days. One month later, I still had not heard back from either Francisco or Oscar. If this is how they treat me just to set up a consultation, I have to believe that this unprofessionalism also reflects in their workmanship and installation. Will not schedule a consultation with them even if they do call back. I found their Operations Manager (Arman Tyfekchyan) on Linked-In. I called him on Saturday, June 4, 2022 and left a voicemail message detailing my experience with Francisco so that he knows how Greco employees interact with potential customers, noting that I would not use their services. He did not call me back to apologize or to inform me that he would look into it or make any corrections. read more

Greco to our rescue! After strong winds our daughters bedroom window was shattered. We called Greco and Arman was extremely nice and quick. He came out to measure within 2 hours. His installation team was on time and very professional. We will definitely be doing business with Greco in the near future. read more

DO NOT USE THIS COMPANY! They bait and switch, doing one thing then doing another. The clueless are paid off, he gives them a deal if they promise top write a good review here but the real installation is sub-standard and poorly installed. I'd check out other vendors and stay safe. NOT a fake review unfortunately, wish it was, I got taken by this company and have proof on invoices, texts from th owner and payment history. read more

Absolutely, outstanding company. Great service, great employees and great product. The installers were terrific, my windows and new front door were installed perfectly and look fabulous. Terrific value. read more

Competitive pricing and exceptional service. We got 14 Milgard windows and 2 patio doors, which were installed the day after they were delivered and it only took a day and a half. They did an excellent job on installation, explained the lifetime warranty and touched up anything we asked for right away. They also gave us the best price we could find. Highly recommend read more

Excelent service: timely, very professional. We are happy with the result. Arman is really professional and responsible. Very happy with our choice. read more

I called Greco after dealing with other window companies and I am so glad I did. This was a very complicated order and everyone I spoke to made it sound like it was so difficult to do . . . until I met Nick! He honestly came in and within 30 min we had a plan and how we were going to handle it. My windows are installed and I could not be happier. Besides the great customer services from start to end, I ended up with the best deal out there for quality windows. Thank you Nick for all your assistance and I look forward to working with you on projects to come. read more

Hmmm....not sure if anyone works there or even if this business is even still operational. Nobody ever seems to call you back nor pick up the phone. I truly wish them (if they're still in business) the best of luck. It sucks when a family business goes out of business. Ugh...makes me feel so sad. I wish them well. read more

We shop around first like all other home owner before going with Greco windows. They offer good price like others but they have better reviews so we chose Greco and we are so happy we chose them. Best price , best customer service ( Nick ) best window ( milgard) best installation ( Noel and crew ). Milgard delivered 11 windows and 2 doors on the promise date. Noel and crew Installed everything in a day. Nick answered all questions and gave us some advise on choosing right windows. Nick Gave us the good deal right away. We need to wait almost 3 months for the windows and doors because they are made to order but it is worth it. Everything is smooth. If you are looking for windows and doors, i recommend Greco windows. read more

I worked with Francisco to replace 15 windows in my Pasadena home. I based my decision on Yelp reviews, and I was not disappointed. He gave me an excellent price, there was a lot of communication, and he knew what window locations that they City of Pasadena would require tempered glass. His workers were clean and fast, there was nothing I could complain about, and I am a bit picky. Francisco was responsive, resourceful, and got the job done. He is probably happy to have me finished up because I asked a lot of questions, but he always answered them all and knew his stuff. read more

I provided them with some contact information it was on a weekend.

Very nice person nick came to my house and took some measurements and discussed with me what I'm looking for, he answered to all of my question and concerns and provided me with clear answers after a day he emailed me with detailed pricing , also he asked me to stop by his office to show what are the product type that they offer. After my visit I was very happy that I got to the right company to do the work. We discussed the process and made the deal. It took only two weeks to call me back that my order is ready to install, I was very impressed with the call. We arranged the installation and that was it, very professional people came to install and in 3-4 hours the job was done in perfection. I got the best deal both price wise and quality.

Outstanding service! I researched several window companies and they were the best. Prompt and courteous customer service and they offered the most competitive prices in the area. I found them through the milgard website as a Certified dealer. I ordered two patio doors and three windows for a two bedroom second floor condo. They measured and ordered the windows. They arrived in three weeks. The installers (3 man crew) came the next day. All windows and doors were installed in one day. I couldn't be happier with the product. It's cut the road noise by 90% and they look great. I've already recommended them to my friends. read more

I recently ordered a window at Greco. After waiting 9 weeks for the window to arrive from the Millgard factory, the window was finally delivered.... damaged. Nick work with them and managed to have a replacement window in 3 days!!! I'm very pleased with their professionalism and will use their services again read more

Outstanding speed and efficiency. Needed three windows double-pane and the process was seamless. Gave us a VERY reasonable window of time for arrival and completed the job faster than I could imagine. Quality above par. I see that on some reviews people complain about being unable to contact the business. It is true that they are out of the office often, but usually on jobs and once you get in touch (going in is best) you can get the leads cell-phone number and this alleviates any communication issue had. read more

Loved their work. Quality work for a great price. Replaced our broken stain-glass bay. Did a beautiful and careful job. Would definitely recommend. read more

i called this company for a quote on repairing/replacing a large window (the best part of $1000 worth of work- based on other quotes). i was forwarded to Jerry. He was pretty short on the phone when i first called- but i know what its like to work in the service industry so i wrote it off as a "long day"- i followed up sending him reference photos, measurements and other info to help the process with the response of: "i'll talk to my partner and get back to you with a price". i stressed that it was time sensitive and was assured it would be a "quick response- as soon as i talk to him".... 10 days passed with no response- i called twice with no response. i just called again to follow up (again with "grumpy Jerry" as I'm now calling him)... he remembered me, so i assume he remembered it was time sensitive/got my messages- because he was even more short with his responses... i barely finished my question when he snapped that he wouldn't be able to fix the window... fine, not a problem- but as i was then asking if he knew a place that would be able to help/replace the widow he hung up on me. sorry but this customer service is not acceptable- maybe greco is better as a company- but they still get one star from me I'm afraid. very unimpressed. if i could give less i would. read more
