    What a pleasant experience it was working with the owners Justina Sigle and her husband on picking out and installing a large "fiberglass" Picture Window by Marvin? When Mr. Sigle came out to measure my large old Picture Window that I wanted replaced, I also showed Mr. Sigle my granddaughter's vinyl window in her bedroom. In short, it would hang-up and wouldn't open. Interestingly, Mr. Sigle told me the vinyl window itself was still in good condition, but the slide mechanism just needed a little tweaking adjustment. Twenty minutes later, the window opened and closed perfectly. When I offered to pay Mr. Sigle for his time and effort for fixing the window, he refused to take my money. A couple days later I got a very fair price from Justina and placed my order for a large Picture Window by Marvin (i.e., sturdy fiberglass construction, Low E-3 glass with Argon Gas.) A few weeks later, Window H.Q.'s installer named Tim came out and demoed-out my damaged old window and installed my beautiful large Picture Window by Marvin. My new window is gorgeous and Tim and his crew did a great job with the installation process. In closing, I highly recommend the Window H.Q. Company in Costa Mesa to anyone looking for a quality replacement window for their home or office. And, very nice people to do business with. Bob S. Norco, CA

    Top notch team, we scheduled bill for measurements and he was on time and ready. Bill was very attentive to our needs and explained in detail the benefits and negatives of each type of window. Two weeks after measuring we scheduled the install. It was a crew of three and they knocked out the job in a few hours. Great work and highly recommended!

    My gorgeous doors

    I had my front doors designed and installed by Windows HQ and I couldn't be more thrilled. Murph and son Jake did an exceptional job....everyone that sees it is in awe. It transformed my entire entry way into relaxed joie de vivre as I look thru them into a beautiful entry garden. The finish work was extremely important to me as I am such a perfectionist and it couldn't be happier, inside and out. I give Windows HQ 10 stars.

    The five vinyl windows were replaced by these casements.  Worth every penny!

    I embarrassed to say, it has taken me over two years to write this review. My tardiness in no way conveys how happy I am with the product or service I received from HQ Windows. Prior to selecting HQ I searched high and low for a quality window company I felt I could trust as I was doing a full home remodel. I interviewed about 10 different companies. I landed with Justina at HQ and she was on spot with everything. The Marvin product she suggested was an excellent choice and I could not be happier. I would recommend this company to anyone who desired high quality products with excellent service. Bravo Justina! I still adore my windows :)

    I worked with Tim and Joy at window HQ and they were fantastic. Came out quickly, gave me a reasonable price, and my windows/slider were installed a little over two weeks after I ordered them. They look fantastic.

    Finished Project

    This review is long overdue! We were in the final stages of a whole house remodel and wanted to replace a sliding glass door and garden window in order to install some sort of folding doors. I did lots of research and then ran across a company called Window HQ, only a couple miles from our house. I went to their store and met Justina, who was professional, courteous and very knowledgeable about product options. She introduced me to Murph, who gave me a tour of his workshop and it was plain to see he is highly skilled and organized. I had Murph come out for an estimate and we decided on getting bi-fold doors made by WinDor in Brea. When the doors arrived, Murph's team did the demo and installed our new doors. They protected the interior of the house and cleaned up at every stage as they went from start to finish. My wife and I are totally satisfied with the great work they did and we love our doors. We've had several parties and have opened up all the doors making our living room part of the covered patio...perfect! Our friends and family all say what an improvement the doors make. Murph and Justina have high-integrity and we couldn't have had a better experience from start to finish. We highly recommend and trust Window HQ.

    Dan -- OCContractor, Inc., Orange County, CA My relationship…read morewith the Conkle family goes back over 45 years. Long before fax machines, pagers, cell phones, or the internet, I was driving out to their location on Katella Avenue in Cypress to place orders in person, grabbing lunch at the little Chinese restaurant next door before heading back to the job site. That's how far back we go. Over the years I worked closely with Victor Conkle, and watching this family business grow has been something special. Today, Dallas and Jeff Conkle are running California Windows, and they have taken everything that was built before them and grown it into the most reliable, knowledgeable, and trusted window and door company in Orange County. In all that time, one thing has never changed: the Conkle family and their team are simply the best in the business. The consultation, the measurements, the product selection, the installation every step is handled with a level of professionalism and precision that is genuinely hard to find. Installations are as close to perfect as anything I've seen in this industry. There's a reason they've outlasted so many competitors over the decades. When times get tough in construction, the companies that survive are the ones that earned their reputation through actual quality and reliability. The Conkle family did exactly that. Whether you're a homeowner, a remodeling contractor, or a production builder in Orange County, if you're looking for people you can trust to do it right the first time, look no further than California Windows. Dan, Owner -- OCContractor, Inc.

    Jacob and his team were alway on time, cleaned up afterward. Great quality and price.read more

    We'd been having issues with our entry door for a while. The door is more than 80 years old. And…read morenow, it had started rubbing against the side wall and no longer sat evenly in the frame. It was clear it was time for a replacement. Before choosing James, I got a quote from a very popular windows and doors company in Orange County. James, the owner of Lucero's Windows and Doors, not only offered the best price but was also extremely responsive. He mentioned that he previously worked as a Home Depot installer, which gave me confidence that he was properly trained. I was initially cautious because of the low number of reviews, but the consistent perfect scores from other customers made me optimistic. Now, after working with him, I can confidently say that Lucero's Windows and Doors is the real deal. Because our home required a custom-sized door, James came out twice to take measurements. After about two weeks, the custom entry door arrived, and he completed the installation in a single day. He told me our home was one of the oldest he's worked on, and the walls were very different from newer builds. Despite the challenges, he made everything fit perfectly, and the final result looks fantastic. We no longer feel a draft under the door, and it swings smoothly without any issues.

Very communicative and on top of things even before we confirmed going with him. The price. James's price is competitive, we also reached out to other door vendors in the area, his price came back within our budget. He's also very knowledgeable about the product and can tell he's been in the industry for a long time. It took James 2 days to get all doors installed. He was courteous and mindful getting work done. We had one door that had some problem with our floor not leveled, he assured us it would be resolved. For the utility door, the quality is above our expectation as an exterior door that not guest facing, and he complimented the hardware for us without charging since our own hardware is garbage. My partner is a very peculiar person with details. He's very happy about James work that alone speaks his work quality. I would definitely hire James again if we have door or window job, would take his referral for other jobs needed!

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.
