Aluminum Series Casement Window is rated 3.9 out of 5 by 215.
Rated 5 out of 5 by from Great Windows I really love my windows. They look great in our modern studio loft. They open and close easily and really block the harsh sunlight. I'm so happy I did a little research beforehand.

Rated 5 out of 5 by from Oustanding, and stands the test of time. I bought Milgard aluminum windows in 2010, 9 years ago for the upstairs of my home, 6 windows total. The windows are rather large, the smallest about 5 feet in width and 30+ inches in height, the larget 8 feet(double sliders). Could not be happier. ALL of our friends were convinced their vinyl windows of various brands were superior. Well, after 9 years, some of them are replacing their windows due to the fading and scratching...not to mention the shaking of the windows during high wind events. Please continue to offer these great windows.

Rated 5 out of 5 by from Beautiful Aluminum patio door and weather tight! Southtown Glass here in Salem, Oregon just replaced a leaky aluminum sliding patio door in my mid-century modern home with a new Milgard Aluminum one. Because the door fin couldn't be used in this application, Southtown Glass made a z channel for the bottom to keep out the rain in this south-western exposure and added a water barrier under the door frame; it rains a lot here in Salem and so keeping the rain out was a requirement for choosing a door and installer. The door is beautiful and maintains the mid-century modern look of my home: I choose anodized aluminum to match the other original sliding glass doors in my home. Thanks to Southtown Glass for an expert install and Milgard for an excellent product. I'll repost if I have any issues down the road.

Rated 3 out of 5 by from Look good from far away These windows look absolutely great from a distance. The detail work is terrible. Many of the weather stripping seams are twisted in the track and not fully adhered at the corners. have submitted for a representative to orchestrate repairs and haven’t heard back yet. Will update review when they are done. Overall not happy with the details after spending $15k on windows for our new construction custom home. They do look beautiful overall though.

Rated 2 out of 5 by from Need help! Overall I am happy with the product but I am very dissatisfied with the dealer (California Window & Door, Palm Desert, CA) that sold me the sliding glass doors and fixed windows. I have one large picture window that was either measured wrong or installed incorrectly and is not properly sealed. I had the dealer come back last summer after install and they told me I had to contact Milgard about the window that is not correctly installed. When it rained hard this winter the window leaked all over my new wood floors and I had the dealer come back out and they put some caulking around the outside of the frame and then sent me a bill! I am definitely not paying that as the window is still not properly sealed and you can push on one side and you can see light through the frame from the inside. They need to replace the window or make it right. I am reaching out to them again to come back and fix. Milgard needs to properly vet their dealers.

Rated 5 out of 5 by from Best customer service I have custom built home in Sammanish. We had all new Milgard windows installed recently and love them! The customer service was outstanding and the quality of the work is excellent. I am very happy with this company and their product and will recommend them to my family and friends. Thank you Milgard the excellent service.

Rated 2 out of 5 by from Hideous handle The sliding doors themselves seem well built, but the handles are these huge surface mounted blocks of metal. Ugly! And the screen door is a joke. I’ll be shocked if that lasts a year with kids going in and out.

Rated 5 out of 5 by from Big View I needed the weather cooperation for the install. Finally a break in the rain after a month of waiting. These windows enhanced the views by giving me a bigger picture frame to view through. No observation of weep holes will be visible where air and insects were entering the home. The awning features and the big view is what I wanted for this home. I am pleased!

Rated 2 out of 5 by from Window Leaks My window was installed in early January of this year and although it looks nice from the inside, it leaks everytime it rains. This is not right. My whole condo building is having all the windows replaced, and multiple windows have leaks. Very frustrating experience.

Rated 5 out of 5 by from The difference was remarkable Replaced single pane sliders with Milgard dual pane doors and windows in our living and dining room. The difference in our view is amazing as the new windows do not have a brown tint like our previous sliders! We cant wait to experience the energy savings this summer when the temperatures regularly exceed 100 degrees. We are so pleased with the look, we are also going to replace the windows in our kitchen with Milgard Windows.

Rated 4 out of 5 by from Perfect replacement for 1960's home Milgard's Aluminum line is the perfect replacement for our 1960's mid-century home. They aluminum frames 'disappear' so you only see the view and not the frames. We'd have given it 5 stars except that we aren't crazy about the latching mechanism on the double sliders. Where the two doors meet the mechanism itself lacks a cover plate so you look at the strike area and the springs/screws and it looks unfinished - like something is missing. On the single slider that latches into a wall there is a cover and strike plate but on the double slider there is nothing. Please, Milgard, come up with a more finished look and send us something when you do!

Rated 5 out of 5 by from Mid Century Modern Replacement. We have a Mid Century Modern home and over a year ago replaced 2 sliding glass patio doors with Milgard Aluminum Series mill finish doors. They are still working fantastic and look perfect. One of the doors is the major traffic flow from the house to the outside so it gets used all the time. They are extremely sooth operating and lock securely. We love this product.

Rated 5 out of 5 by from MCM Alum Doors and Windows - Awesome Product! Remodeled a Mid Century home in the Hollywood Hills -- Replaced all the windows as well as 4 sliding doors with clear anodized XO and OXXO alum doors. LOVE them. They worked great. Anyone complaining below about functionality *may* have not hired the correct installer! Do NOT cheap out on window and door installation and WATCH your installers -- ask questions!! The quality of the door is totally negated if improperly installed. My ONLY issue with the door is that I would like a more modern low profile handle. The hoop handles are ok, but a more sleek Fleetwood style handle would be ++++. At least they did away with those lame wood handles on clear anodized!!!! Thank you Milgard. I'll be remodeling a new house soon and gonna get them in bronze (black) next.

Rated 5 out of 5 by from Custom Aluminum Awning Widows I ordered two custom aluminum awning windows from Priority Door and Window Products in San Diego in mid-December, 2018. Within about 5 weeks, Milgard delivered the windows. However, one of the hinges was missing a screw for the awning window bracket, and the windows weren't aligned properly. But, within two days of installation, Milgard was on site with their field tech support team to install the missing screw and align the windows properly. Overall, my experience with Milgard was excellent. While they said it would be at least a week before they could make the repair and adjustments, they responded in a timely and positive fashion to rectify my situation. Certainly, this is a superb reflection of the kind of company Milgard is -- customer service oriented and the spirt and intention to "make things right." Regarding the product, the windows are high quality and great value in every respect. I would highly recommend Milgard products.

Rated 5 out of 5 by from Remodel Window Bought Milgard Aluminum window as part of recent kitchen/bathroom remodel. Window matches, similar windows installed in 2015. Though windows were 4 times less costly in 2015. Very pleased with look and quality.

Rated 5 out of 5 by from Great Customer Service I bought my windows a number of years ago but a few became difficult for me to open and close. I contacted Milgard and from that first conversation I knew I was in good hands. Efficient, professional and kowledgeable customer reps. Serviceman came and identified the problem. An appointment was scheduled to fix the problem. Today, serviceman came on time, when scheduled, and fixed the windows without charge because of their amazing guarantee.

Rated 1 out of 5 by from Patio doors leak and do not close properly We bought a few windows and three sliding patio doors, we had them installed by the recommended installer by the milgard reseller, one of the doors could not be locked due to the door having the wrong doors on a frame meant to open on the opposite side, Milgard kept sending the wrong hardware and it is 3 moths since they installed and the frame has yet to be replaced. On our huge 4 panel sliding door it does not close properly so when it rains there is water on the inside of the house, the rubber seals between the aluminum and the glass is also not seated properly, and the door is extremely hard to open on one side and the other side is fairly hard opening, not opening as nicely as the doors they had in the showroom at Tri Supply in Austin. I hope the service will and warranty will take care of these issues, I guess time will tell

Rated 5 out of 5 by from What a difference!!! I just bought these windows and right away we can tell the difference, it used to be so cold in our bathroom, when we just had the window installed, now we can feel the heat, and the same goes for the kitchen window...So glad I purchased these windows.

Rated 5 out of 5 by from Thermal break aluminum window frames Much better quality than the vinyl windows. The black frame Windows look better against the natural wood wraps. No warping problems like the vinyl. The window Glides nice year-round no matter what time of the year you have to open or close the window it doesn't feel stiff like the vinyl windows do. Cuts the outside noise down way better than the vinyls do. The thermal break prevents sweating. I've completely switched over to the thermal break aluminum windows. As far as I'm concerned I will never go back to the cheap vinyl frames.

Rated 5 out of 5 by from Excellent construction quality I have had Milgard windows since construction. I have been gradually replacing the original windows for double pane units. They are very well made; and, the company always takes care of any complaint.

Rated 4 out of 5 by from good quality window I ordered several windows of the same size and they were consistent. 5/5 there. Most had some aluminum shavings in the wells of the aluminum extrusions. I will definitely ding Milgard for the phone and web support. NOWHERE on the website are there any installation instructions for BLOCK FRAME aluminum windows. the "Chat" on the website was worthless, and the phone support was worse. The woman I spoke with had the perky voice and all, but almost no knowledge of the product. When she finally understood the issue, she was similarly unable to help, referring me to the trade association for aluminum windows! ha! When I pointed out this absurdity, she became snippy and hung up on me. Waste of my time.

Rated 5 out of 5 by from Love the warranty on Milgard windows They are the only windows I would put on my house. I have double paned windows and the one time moisture collected between the panes Milgard took care of the problem at no cost to me.

Rated 2 out of 5 by from Poor Design Ordered bronze, almost black color aluminum. Screens are shimmed with white plastic, very obvious. Also had to replace two out of three windows due to seals breaking and water trapped between double glass, lifetime warranty.
