We've had IWC windows and a sliding door for many years and have had 0 problems. Friends purchased another company's windows and within 5 years moisture built up within the glass panes. I would recommend IWC to anyone. read more

I just got replacement parts for my window, Sandy was great and sent me the part right away.

RUN! RUN QUICKLY AWAY FROM THIS COMPANY! Absolutely beside myself that we have been lied to for over 3 months waiting for our oversized window. We have email documentation going back 2 months and telling us new ship dates so that our local installer can come and install it for us. We have checked on its progress several times as this company has not been proactive in communicating with us or honest even in what they do respond with when we finally do get a hold of them. AND if they knew they had a problem with their production line, why can't they pick up the phone and call the customer? They certainly had no problem taking my money first and then couldn't hold up their end of the deal. I have gladly cancelled my order because they have lied too many times and are now saying it will be another 3 weeks. Why in the hell would I believe / trust anything they say? RIDICULOUS COMPANY. SHOULD NOT BE IN BUSINESS AT ALL. read more

Had some minor issues with some of my windows. I expected a to get the he run around or a bill to get them fixed. Aaron came over figured out the problem and fixed the issue, and they never sent me a bill. I would totally buy these windows again. read more

My 10-year-old IWC windows fogged so I called the company. The receptionist said the company was sold and the new owner "chose not to buy the liabilities" of the old company. This says a lot about the new owner. Apparently the new owner offers his "lifetime warranty" with any windows bought from him. The catch here, of course, is that the new owner can sell the business or file bankruptcy at any time and whoever buys the business can "choose not to buy the liabilities" again. And so the cycle repeats itself. Buyer beware. This is an unethical owner and an unethical company. I highly recommend not doing business with them. read more

Lifetime warranty doesn't exist.This company filed bankruptcy and changed ownership twice, and guess what happens to your lifetime warranty? Yea you have none ! Stay with we'll known company that been there for generations read more

I have experienced the same issues as everyone else here; several of our windows and doors are all fogged up to the point you cannot see outside and they are not honoring the lifetime warranty. Has anyone submitted a BBB complaint? Or has anyone proceeded with legal action? If you have, please let me know, I would like to find out if you have had any success. read more

The same thing happened to us. After the bankruptcy, the company who supposedly took over with all the same account #'s, phone numbers and employees! The business is identical in every way from before the bankruptcy! I sent in a deposit check to place an order, they received it, cashed it, then went out of business at the same time. That was for $3,000.00, my personal windows are also failing. Let's get together with Eyewitnesses News, Chanel two Christine Lazar to get some answers for everyone! Yes, I'm one of their retail dealers! They don't deserve any stars! Can be reached at (bonsai420gardens@gmail.com) if anyone has an interest into the truth!! read more

I too have a home full of International windows. I selected International because they offered double-paned black grid windows, which I love at a reasonable price. I too have experienced repeated fogging in my front window. I've been told this is a broken seal. International replaced the window after considerable effort on our part, including a trip to their corporate office. Then some years later the same window failed again. International was in the process of replacing it, when they closed their doors. We never were able to get an installation date scheduled. So today we have a front window that is defective and the new International Window company will not cover the original lifetime warranty. So very disappointing. We are in the process of having the window replaced with a brand that has been around for many years and has an excellent reputation. Looking back, I wish I had spent a little more money and gone with another window company. read more

I must admit, I was disappointed with this company from contact many years ago. However, the current team is fantastic. Extremely nice and responsive. They followed up on the challenge of finding parts for my windows which are no longer made. Not only were they able to find a creative solution - they sent them to me as a courtesy. Thank you to Kayte, Catherine, and Oscar! read more

I had International Windows installed in my house in Lake Elsinore 12 years ago. They are still in and having no problems. The change in temp was amazing. Turn on the air and the temp stayed very nice. I really loved the Lunai French doors. They work really well. read more

I've read everyone's reviews and it's a shame this company is still in business. We have had the same issue - a cloudy windows, a Life Time Warranty certificate but the company will not honor it. Basically our story is the same as Linda G.'s and several others that have left reviews. BUYER BEWARE: IWC is still manufacturing the same windows people! With all of the poor reviews, you'd be crazy to use them. Also, we're looking into the legalities of this company's claim that they are not responsible. Let me know if you're interested in this as well or if you've looked into it and have helpful information. read more

We bought a house with IWC windows about 5 years ago. One of the locks on the window was broken so I reached out to the company and they are sending us a new lock. For FREE! Great customer service. read more

Contacted International Window Company yesterday to see if my window night latches could be replaced. They were very pleasant and helpful and gracious. Received the night latches TODAY via UPS. I could not be happier. I purchased windows from another company a few years ago and the quality does not stand up to IWC. IWC windows are built to last. read more

We purchased this companies windows in our new home with lifetime Warranty. Three of our windows became so cloudy that we can no longer see out of them. When we called for replacement windows, we were told the company, who still has the same name, phone number and address, had filed bankruptcy and would not honor their warranty. read more

This company is someone you don't want to do business with. I had French doors put in 2 years ago, were one never has worked properly, paid 2500.00 for it. Their customer service sucks. They don't return calls nor have they fixed or replaced my door as they should have. So, if you do go through this company for anything I promised it is a mistake!!!!! read more

This is a scam... they took money out of my account ... money that I have no idea why, now I'm asking for a refund they're telling me that you're only allowed one refund per year .... what kind of nonsense is this ....... it's a scammmmmm read more

I have a six unit apartment building that was retrofitted with IWC windows. About one in every three of the windows is in disrepair, and the quality is cheap and not reliable. I emailed the company to ask about getting replacement parts, and have not heard back, so the quality of service is it the same poor level as the quality of their windows. read more

My windows were installed in the early 2000's... I just noticed that two of the windows had an odd/ugly swirling discoloration that has developed on the outer (or perhaps inner?) surface of the panes. These windows are in different areas of the house, and other windows around them appear to be fine, so this looks to be an obvious manufacturing defect. Upon calling to submit a warranty ("lifetime") claim, I was informed that the company had declared bankruptcy in 2011, voiding all warranties prior to that time, so they would not be honoring the warranty. Speaking to the installer (not IWC) who actually did the work, he told me that IWC is still operating out of the same facility, under the same name, and putting out the same product. My interaction with the installer led me to assume that this is not the first problem they've had with IWC windows. It seems to me that IWC filed bankruptcy to get out from under their warranty obligations and then opened right back up and continued with business as usual... Even if this is legal, it's certainly not what I would consider ethical. read more

International Window - Swirling pattern on the window to the left is NOT dirt. IWC refuses to honor "lifetime" warranty, citing 2011 bankruptcy. - Building Supplies Near Me - Corona, California

My new apartment has IWC Windows. They are wonderful. Nice double paned glass and I can't hear the highway which is right outside the complex. I'll update with photos in the future, but again I think a lot of these reviews are misled or bogus. read more

The customer service is awful ,built house in 2007 with a lifetime warranty which they will not honor, every handle of every slider in the house has broken a defective product obviously and dangerous, plus most of the windows and doors are now cloudy, talked to a lawyer they don't really believe that they can actually not honor the warranty their liability has been dismissed but they should be standing behind the products warranty, same name, same tooling ,just a sleazy company beware ,stay away . the positive feedback I'm sure they must have been paid, I think a call to California's Attorney General consumer protection department is in order, after many calls they sent me to a glass shop to purchase a handle but the company they sent me to won't deal with them either read more

Wow.... This poor company is getting hammered here....I guess there's truth to the saying that a happy customer tells one person and an unhappy customer tells everyone........lol I've had IWC Crown vinyl windows in my home for over 10 years with no problems they still operate great and the glass is still clear .... just my 2 pennies .......... read more

my builder put the IWC windows in my home 11 years ago and we started having issues about 3 years ago. Tried several times to get someone to help and never even would get a call back. The trim has fallen off of every single one 52 total and it isn't something you just snap back on. They are warped from the AZ heat and all need to be replaced with new trim which was supposed to be covered by warranty. Now mold issues are occurring due water getting in around the area where the trim was supposed to be. The 2 bay windows started leaking about 5 years ago and we have had to reseal them every year ourselves. Now I realize the the entire top of one of the bay windows has not been completely sealed, water has gone inside, mold has started to form and the entire top piece of glass literally lifted off the base with one finger. The entire bay window will now have to come out. Huge expense for me. After contacting the company I found out what everyone else has in regards to them not honoring the warranty. I think this is a cop out for companies and they have only been able to get away with it because no one has filed a class action law suit over it YET, which I will be glad to be a part of if someone does. Once that happens then IWC will realize it would have been more professional, honest and the right thing to do. Plus just think about all the happy costumers they could have had spreading the word about how great this company was instead of being here giving nothing but bad reviews. Sad that a law suit will need to happen to set president for all other companies that do this maneuver too. It will happen eventually it always does. History has proven it. IWC advice***** In today's society of social media and the way people communicate with the click of a button world wide. it is not a good idea to screw people out of their hard earned money and not back up your company name or warranties. Lesson learned there is no such thing as :LIFETIME WARRANTY: , there is no such thing as :LIFETIME WARRANTY:, there is no such thing as :LIFETIME WARRANTY: & DO YOUR HOMEWORK read more

Reading all the reviews about IWC is very interesting, and right on point. I am also a home owner that replaced all of my windows and i am just watching them just fog up on me. Some lifetime warranty! And they care less of the issues that you are having... But they will sell you the same product again... I guess we are boo boo the fool...... I would suggest reconsidering investing your money in IWC if you need windows for your home.... Why even offer a life time warranty? ( I got it, to make money) read more

I just called for a warranty problem with my gas filled windows which were installed by Hardy windows and we are getting moisture in between two panes of glass and it is leaving a film in between the glass so the argon is leaking. So I called for warranty and they don't fix any warranty before 2011 because they went bankrupt and also in 2006 if you check your paperwork so now I have $16000 worth of windows with no warranty and I'm getting ready to do my rental. Maybe Milguard read more

My new home had IWC windows with a "Lifetime Warranty" installed by the builder. Many window seals have gone bad. IWC filed for Bankruptcy in 2011 and was purchased by another. But it is still operated by most of the same people under the same name. Do an online search under IWC bankruptcy. They will not honor the previous "Lifetime Warranty". I have had most all of my windows seals go bad on my new home and now I am stuck with no Lifetime Warranty as promised. These windows are junk and I wouldn't install them on a cardboard box. read more

Jeannie was fantastic. When I called I wasn't sure what parts I needed. She explained everything and sent out the replacement parts right away. 1 day later the parts arrived by UPS just as she said. The window is working great - like new again. read more

Do not buy! Will not honor their life time warranty before 2011 due to bankruptcy. Seems like they just reopen every ~10 years under new ownership to skip out on warranty claims.... read more

DO NOT, I REPEAT, DO NOT buy ANYTHING from these clowns. As previously stated they DO NOT honor their "lifetime warranty". I called in to inquire about this supposed "lifetime warranty" on a number of Windows in my house and was informed that they had gone through a bankruptcy restructuring and because of this, the "lifetime warranty" was no longer valid. I told the woman in customer service that it seemed like I had made a bad decision to go with their products and maybe should have chosen Milgard. She told me "I'm sure you'll be happy with Milgard"!! Now THAT'S some customer service. If you are an employee of this fine company, I would start sending resume's out right away. You'll all be looking for employment soon. My guess is, this isn't going to be their last bankruptcy. With a company policy of not standing behind their products, I sense another one coming shortly. I will spread the word about your products and let everyone know about them and your shady business policies. Off to Milgard!! read more

Do yourself a favor. ASK your local glass company how they would rate these windows and sliders? Compare to Millgard. I respect a company that keeps it's word and honors the warranty. This one does not. I've told everyone in the business not to buy IWC... I replaced all the windows in my home with IWC. The low e has failed in 3 of them. The windows I bought had a Lifetime Warranty. I was told the Old Co went bankrupt and someone purchased the assets of Old Co but not the "Lifetime Warranty" liability. Is this legal or just a 'slide of hand?' New Co, operating under the same name as Old Co is refusing to honor Old Co's "Lifetime Warranty" on our windows that are now fogging. The old company made JUNK windows. Now the "new" company same name are without honor. Also trying to get yelp to remove the bad reviews... O IWC - before you ask yelp to take my review down. Think twice. I have the original invoice. I can post that along with photos of the fogged up windows. Anyone wanting a copy of my invoice - let me know. I'm a verified buyer. Don't make the same mistake... or in a few short years you might be writing the same review here. cheers read more

I purchased a home in Southern CA with IWC windows through out and thought 2 of them were just dirty. But the strange marks, like a roound suction cup (?) and streaks are on the INTERIOR of one of the double paned glass. I emailed and no response so phoned and asked if Lifetime Warrranty is truly lifetime and the answer is NO. So I will not be purchasing new windows and needed sliders from IWC. read more

Warning comments on the NEW International Window (Read before buying IWC products, or, good luck with your warranty and service work) First, let me apologize for selling International Windows to my customers. Had I known they would close their doors and not honor the existing lifetime guarantee, I'd have referred you to Milgard Windows. They have been around much longer, and handle their warranty work MUCH, MUCH more efficiently. Next, even though this is 'technically' a new company, so they do not have to honor existing warranties, it is all the same managers that bankrupted the original company. Yes!! The same people that took IWC into bankruptcy, are still at the helm. So, be warned. If you buy IWC products now, you will undoubtedly be faced with the same worthless warranty when your windows begin to fail. (Definition of an idiot: using the same managers, and hoping for different results.) I say this because I did sell International products while selling for a local glass company. Now that I am disabled, and retired, I recently asked for assistance in replacing the glass in my 'worthless' windows, thinking my past association and friendship would help me in purchasing replacements for my failed insulated glass windows. Keep in mind, I did not ask for FREE, I wanted to pay so that I could simply repair the glass that had failed in my windows. I was told 'sure', 'no problem'. But, after four months of no response, and countless emails promising help from they new/old manager, I gave up. So I can't even get replacement parts for the same windows they sell now!! Good Luck if you purchase anything from IWC, you'll need it. read more

Postponing delivery twice in a row, without informing the customer. I've got to know they are not delivering only by calling them again and again... I should have read these reviews before doing any business with them or their retailer. It will not happen again, and I will definitely not recommend them to anybody. read more

My 12 year old IWC windows are also starting to fog. New owner is not honoring the lifetime warranty. DO NOT DO BUSINESS WITH THIS COMPANY!!! read more

Purchased 6 windows and a slider door (vinyl) in 2006, did not get the gas filled because then as is the same as now was told it is useless do to there is not a manufacturer out there who can contain the gas for any length of time, meaning all will fail. Found the Retro-fits to be of high quality and have not had a single problem even though I was told at the time these are middle of the road windows. Bought new house and because this will be my retirement home and I wanted the best, went with another company considered the best - What a mistake! Window shows up with internal grids splitting, screws sticking out, screen improperly installed. Warranty company hasn't contacted yet. Went and looked at my IWC windows and they are still in great condition. I will be using IWC Windows for the rest of windows in my new house as I have learned from my mistake and won't repeat it. read more

I was the developer of an 11 unit condo in which the window contractor installed IWC windows. After the installation the contractor went out of business and I needed to replace the window panes of two windows that were scratched and damaged by the contractor. IWC was. IWC was not helpful in getting those replacement window panes. First, they sent me what they said was the contractor's purchase order for my project so that I would identify the two windows. However, the purchase order did not contain either of the two windows although I identified them on the contractor's window list and window diagrams he had included with his order. They said those weren't sufficient and put the burden on me to take the actual window glass sizes, without searching their records for the complete purchase order. When I hired someone to get those measurements they told me that the moldings on this windows are removed from the outside and since both windows were in the 2nd floor and one was above a sloping driveway, getting the measurements would run several $100. He instead measured the window panes from the inside frame dimension. IWC claimed they could not order the windows based on the inside frame dimensions and denied that the size of the glass panes were a set size larger than the Inside dimension. So I ordered the panes based on other windows of the same size which were on the purchase invoice. One of the panes was the right size but the other larger one was 7/16" too long which we only discovered when the installation company tried to install it. When I emailed IWC about the problem and requested a replacement of the correct size, it claimed that they were not responsible because I didn't point out the problem within 10 days of delivery, a unilateral condition which did not appear on any communication they sent me. They have not responded to my objection leaving me to proceed with a small claims action for the cost of the pane and the $800 cost of re-renting the special lift needed to install it. read more

The locks on iwc windows break if you use them at all,terrible customer service and they don't honor the warranty sold with their windows, stick with a reputable company because this isnt one of them.they file bankruptcy as a way out of honoring warranties so your on your own and forget trying to get parts, they are no help in any respect,go with milgard. read more

Any recommendations from any attorneys out there regarding IWC not honoring pre-2011 window warranties? I have six windows with bad seals that they will not warranty. Mine were installed in 2010! read more

DO NOT BUY FROM THIS COMPANY. I would give them less than one star if I could. As previously posted, the old company went bankrupt and the new company purchased assets but not the liability or "Lifetime Warranty'. Thus, the new company is not responsible for windows purchased prior to August 2011. I was told the new company is going to change their name. But for now, the new company is happy to trade on the reputation of the old company, without any responsibility. How convenient :) I won't buy anything from the new company, ever. By the way, it took me over 2 months to find out they would NOT honor the warranty. Customer Service is as interested in your business as the President. read more
