After talking with and researching many door providers, I decided to the visit Window Guys in Corona. Bill was very helpful and straight forward about the different choices. He came out the following week and measured and I gave him a deposit. I needed to call the Corona store a couple of times regarding the handles, the installation date and once I requested an email photo of the door I had ordered to determine a dog door. The women in the store were very cold and uninterested in helping me. Finally 6 weeks later, the installers came and my doors were put in and looked great. A couple days later one of the screens came partially loose in the slider, so I called TWG and requested someone come out to correct. Was given the run around again and was told someone would be in touch with me... NO one called........so a week later I had another screen company come and tighten. I do not recommend Window Guys as a courteous or professional door provider. read more

Called 3 days ago to make an appt. for a quote. I had to leave a message on an answering machine and it was during their business hours. This company still hasn't called me back. They must be making millions and don't need the business. read more

Have had five windows replaced by The Window Guys this year and have been satisfied with them all. Installation was on time and without any problems. Have lowered noise and heat transfer, soon getting three more to complete upstairs. Thanks for job done right. read more

We had a pleasant experience with our salesman David - he was knowledgeable, answered all of our questions, patient, not pushy, and took his time to review everything with us. Overall we received a great price on replacing our Millguard slider door. Today we had our sliding door installed and the crew worked hard in the rain while installing our door. While working, they answered all of my questions and were careful to not get dust, dirt, or any sort of mess inside the home. Overall we are very happy with our new door and lifetime warranty! Thank you The Window Guys! read more

very pleased with windows that were adjusted - received courteous service & windows are just one of the best - quite satisfied - thank you lucia read more

You are not going to go wrong with this company. Good pricing and they know what they are doing. On time. Big show room and knowledgeable sales staff. Definitely recommend. read more

Window Guys did a great job. They replaced our worn out old slider with a new french door. Looks and works great. The Window Guys were neat and clean. In and out in about three hours. I highly recommend these guys. read more

Very pleased with the lady that helped us in the showroom. Plenty of options available to view. We are still weighing the options, but the showroom and assistance we were shown was very well received. read more

My reply to John M. below under my first review. First of all there was no misunderstanding from my part, I'll tell you why...Bill wrote an estimate with the description of the windows we discussed. I went to your store to verify the description of the windows and to look at your floor samples of the windows on the estimate. Jessica showed me all the windows and doors that Bill had on the estimate including the bronze fiberglass windows that you have on display as I wanted to see the shade of bronze. You have continuesly blamed Bill for an incorrect estimate, you now claim that the description of the windows is not fiberglass but Tuscany and that the price has changed. Yet about a month ago, I received a call from your employee Linda, asking if I was ready to proceed with the rest of the windows. She never mentioned that the estimate was no longer in effect or a price increase. I decided to contact Bill to be sure that the estimate was still good. I asked him to give me a price for the remaining windows and he replied "you have the estimate those are the prices". I contacted Linda to place the order and she referred me to Jessica. Once I started communicating with Jessica the ordeal that I experienced the first time was repeating again (she also kept sending an estimate with the wrong items). As you can see your staff had already shown me the fiberglass windows since the estimate was originated. If the estimate was incorrectly written, this is a reflection of an incompetent staff. All inconveniences I've experienced to this date, it's a demonstration of the lack of professionalism, organization and communication. I'll give you a professional suggestion you should have your staff follow up with the customer after every estimate provided. I am providing you facts and you responded with invalidated arguments. read more

Great experience with the installation of two windows in my front living room 'Dave the estimator came out and was knowledgeable and courteous and followed up to see if I had any questions. The office staff followed up and provided updates on the production timeline and in setting up the appointment to install the windows. The installers were professional and courteous and personable. We could not have asked for a better experience and we love the windows. We will definitely use them again if I decide to do additional windows read more

I ultimately didn't purchase windows from TWG, however wanted to comment on the in-home estimate process. Of all the companies that came out, I was most impressed with TWG, the gentleman that came out was very quick, very honest, and most importantly not pushy at all. Their prices were the cheapest as well, however I ultimately went with another company simply because I did not want Milguard or Simonton windows. The other companies, including the one I went with, played the used-car sales tactics. It's amazing how fast $4500 comes down to $3500. I don't like that, and I don't like how other companies refuse to price things out individually. TWG writes things up very cleanly, so that at the end of the day, after speaking with 10 other window companies, you can sit down and figure out the cost if you decide to eliminate a few windows to save some money. If I were going with either of the two windows (I like Simonton better than Milguard) I would not hesitate to give TWG the business. read more

Very happy with my new windows and sliding glass doors. The Window Guys did a fantastic job from start to finish. The whole installation process was beautifully executed. The team was super professional, efficient and clean. Highly recommend. read more

These guys were great! I had 5 of my upstairs windows replaced. They were on time, cleaned up after themselves and installed great new windows. My upstairs rooms are now quiet, don't let the heat in or out and so easy to slide open and closed. So happy. And they are a local company. read more

These guys did a fantastic job replacing all my windows and sliding doors. They did a really great job with some beautiful interior trim I wanted. Their prices were great, the installation supurb. Being in the wholesales building material business, I knew many businessess that I could use. I chose The Window Guys, beccasue they are stand up reliable and trustworthy folks whose experience is far greater than most. read more

We would like to thank the window guys; Sergio and Arelleo who did our window istallation, ok mostly Sergio! They did a great job, very professional and clean. Plus they had a great sense of humor. They put down carpet cover to keep our carpet clean. Great job very happy would highly recommend this two. Thanks again Tammy and Dora read more

Window guys installed the windows 2 years ago. Since the condo is so close to beach, the seal wore off quickly and leaked during the recent rain. There is another storm coming, I need to have them sealed asap. Called office, Jessica was very helpful, talked to owner John. John worked around the schedule and squeezed me in before the storm. Sergio and Jr came out sealed the windows again, and no more leak. Thank you Jessica and John for sending someone so fast! read more

We had all the windows at our house replaced and we were very happy with everything. The price was great, the company was very professional, the installers did a great job and left the place cleaner than it was when they arrived. read more

The Window Guys were Amazing. The installers were professional and had the job done in 1/2 day. We are very pleased!!!

No problems at all with our window replacement. Pleased with the service and the price. Bill came out to take window measurements, we selected our windows and placed a down payment. The installers arrived on time, and before we knew it, we had new windows. Totally gave our house a much-needed facelift! The whole process could not have gone more smoothly. To be honest, I'm sort of disturbed by the number of complaints about the company, but fortunately we had no issues whatsoever. I have nothing but positive things to say about TWG. read more

Great product! Had a bay window removed and a new dual slider installed. Dave did the sales and measuring, he knew exactly what I wanted. The installers ("Junior") did a great job too. They were polite, efficient, and clean. Takes about 6 weeks from ordering to install, but the finished product was well worth the wait, so plan ahead. These folks know their stuff. read more

Just had a slider installed. They were prompt an clean. Very professional. I will use them again an highly recommend them.

Have had window guys do lots of different things for us. They have redone our kitchen, replaced both windows and doors in our house. Everybody has always been very professional. The salesmen have always been very easy going with no pressure at all. Everyone including the owner John have always treated us very well. I would highly recommend window guys for any type of work, read more

Had all 16 windows in our home replaced. Bill, the salesman, was very helpful in helping us determine the type and style of new window that would meet our needs the best. No hard sell or up-sell. The installation crew arrived when scheduled and did a great job. They installed all the windows in one day believe it or not. Cleaned up their mess and hauled off all the old windows. Office staff followed up via phone call up to make sure everything went as it was supposed to and that we were pleased with our new windows. I highly recommend The Window Guys. read more

I just had my windows replaced by this company. I made an appt. 2 weeks in advance to install because THEY wanted to make sure I'd be there. So, the day of the installation comes and they NEVER SHOWED UP. I called and the woman tells me they are stuck on another job! I told her I took a day off with no pay to make sure I was here for them. She didn't offer any discount to make up for that. She was just "sorry." I guess it's easy when it's not YOUR paycheck. I am happy with the windows and the actual installation . The price was neither good nor bad . Seemed average. I need more new windows but I won't be going back. Had she offered me even a small discount for thier mistake they would have made a few more thousand off me! read more

Poor company - poor work. They installed all my windows and missed one. They didn't leave any leave behinds nor a receipt. They took my money though. I called and called. They gave me the run around for months - then rescheduled and didn't show up or follow up at all. They ignore my calls and complaints into their website. Its been more months and nothing. Abandoning a job is just like theft. Please do not let this happen to you. Now I have to go to small claims court. UGH. Look elsewhere, please. read more

I just had 7 windows replaced at my home. I have older home that was built in 1950's. I had just purchased and my windows were horrible.! I called around for some estimates and when the salesman David came by from the window guys he was very professional and explained everything. I was extremely happy with the price. the day of the installation the installers were at my house by 8 Am as scheduled. Luis and Alex they are the most hard working guys, they did a fantastic job I am so pleased with them. they picked up everything from the removal of all the old windows and cleaned up everything. I cannot express what an excellent job these 2 guys Luis and Alex did. I highly recommend them both!.my windows look beautiful I am so happy and will recommend the window guys to family and friends. Thank you all for a job well done. Sarah read more

Ugh, could not even schedule. The woman that answered was horrid! Uppity and not helpful at all. They would have had a huge order from me...every window in my home needs to be replaced. Customer service folks! I own a business and even I know that you at least are courteous to the customer. read more

These guys know their stuff!! We had 27 windows replaced in one day! The windows look beautiful! They said they would be done around 4. They were completely done at 4:04 . Everything was cleaned and vacuumed before they left. We highly recommend them for your window and slider replacement. read more

The Window Guys installed 19 replacement windows & a sliding door at my house in 2011 (sorry for the late review). Jaz came out and gave the estimate. Everything was up front. I got a total of 5 estimates. They came down in price to match a competitor that was quoting another product. For what I got, they were the most reasonable. I'm very glad I went with the Milgard Tuscany series. Almost 2 years later, windows have been excellent and very easy to open/close. We couldn't be happier with the Milgard sliding door. Love the well designed latch. Installation on everything was outstanding (very clean look). I had a positive experience with The Window Guys and would recommend them to others. read more

I recently replaced all the windows at my house with the Milgard Tuscany series windows. I got 3 quotes and TWG was the lowest. David came out to the house to get me an estimate and he showed up when he said he would. He measured the windows. We scheduled an installation date and the guys came out and installed the windows just as they said they would. Everyone at TWG's was professional and courteous. The installations was clean and correct with no issues. Everything went off without a hitch. No issues, just good quality windows at an affordable price, done when they said and how they said. Couldn't be happier with my new windows. read more

Stay AWAY!!!! Brian (the owner) doesn't tell you anything at all about the window except "they are the best". He wanted me to sign today for a "better deal". What a STUPID GUY!!! When I tried to inquire more info on the window he never returned any calls. Should have read other reviews and save myself the trouble. read more

This is the worst company ever. They don't follow through when they say. The workmen were nice enough but left a mess. When they put down tarps it was only directly under the window, so they tracked dirt and debris all over my house. I had to clean several stains out of the carpet. read more

I just had 10 window installed, including an dual slider and am very happy with the work and process. David, the salesman, quoted me a good price, lower than others I got to begin with. Then, it turned out that I got another $420 off of that when the installers were able to do the installs without the extra labor cost that I expected. The installers were prompt and quick. They cleaned up their mess and explained things well. I will definitely recommend the Window Guys to others. read more

I had my home windows installed in April 2015, the guys did a terrific job!!! Their installers were neat, courteous, and respectful. I was very happy with the install. In July, one of the windows had an issue with the adhesive used on the frame of the window. I immediately called the Window Guys to report the issue. I was told that the window would be taken care of, and they would call me with an appointment time and date to fix the window. After 2 weeks of not hearing from them, I called for an update, I was informed I was on their work schedule and I would be hearing from them soon. Two more weeks passed and I had not heard back, I placed another call. I was told I would hear from them within the week. Another week passed and no "fix it" date had been scheduled. It took 2 months for my window to be fixed. Each time I called they said they were booked with new installations and did not have anyone available for a quick repair. My gut feeling tells me, they are too anxious to get paid for the new jobs, so they can let the already paid installations wait on the back burner. Not a good way to treat your customers. I had every window in my home done, I guess they figured there was no more money to be made at my house so there was no hurry to repair my window. read more
