French Sliding Door

French-style Sliding
Ultra Series French-style sliding patio doors give your home a touch of elegance. On a French door, the lower rail is taller than the top and sides, which is aesthetically pleasing to the eye. Sidelites can be added to any operating style.

In-Swing French

In-Swing French

Ultra Series French-style in-swing patio doors can make an impact on the look of your room. The door swings inward for an elegant entrance into your home. This style is ADA compliant and ideal for rooms with ample interior space to allow the door to swing freely. Creates a beautiful double door look.

Out Swing French

Out-Swing French
This high performing door can bring a classic, timeless look to your home. With Ultra Series French-style out-swing patio doors, the hinge is on the exterior of the door, allowing the door to open outward. This style works well for homes with spacious patios and is ADA compliant.

Rated 5 out of 5 by from Amazing Door. This door is more solid that he solid door that we replaced. I didn't think that possible. We absolutely love it!! it looks perfect like it always belonged there. The added screen feature we are for sure going to love this summer! Everything came pre-installed, all we did was put it in the hole in the house, and poof it was perfect! My only problem was figuring out how to operate the handles. That was a learning curve, as we had no directions included with our door. When we figured this out, it was a very impressive door, with amazingly secure feel. Would order from Milgard over and over! Thanks!!!

Rated 4 out of 5 by from Very Attractive Sliding French Door Overall, a very attractive sliding French door, and I am happy with the purchase, with one small exception. The secondary lock which keeps the movable door locked to the fixed door during high winds was killed through the fir trim leaving a narrow ligament of wood which is not supported, and deflects when you push on it with your hand. This is a bad design detail and will not be durable. I ordered a total of six doors, and one was already damaged at this location on delivery. This could have been avoided with a metal backing plate, but it was not designed with one which will lead to premature failure of the wood. This is the one detail I am not happy with, and I have already submitted a warranty claim on the one damaged door.

Rated 5 out of 5 by from love the look of the windows We just purchased these windows to go with our complete home makeover. They are beautiful windows that go with the look of our home with very little maintenance which is why we choose them over wood windows. I can't wait for summertime to come so I can have all my windows open, letting in the nice cool breeze.

Rated 4 out of 5 by from Beautiful door / lock issue My contractor just installed it today. It was replacement for the existing sliding door and it was nice and easy process. Except the door handles were not working finally after calling to the dealer we found out it needs more force for the first time to move the handles. It worked and we could open and close the door. However this time the key would not work! basically we could not lock the door from outside! so no I need to contact Millard for advice. It gets locked from inside but cannot be locked with the key. despite of the nice quality fiberglass door I am really disappointed with the lock and handle hardware.

Rated 2 out of 5 by from I am not impressed I just had two windows installed, previously one sliding glass door . The slider has slid easily. It could not be adjusted with the provided mechanism. We have lived with it for a year and a half. Now I have had two windows installed. Latches were not properly placed in two cases for the two windows

Rated 5 out of 5 by from Milgard Ultra series for whole house We got bids from 3 different companies, including Renewal by Anderson and Pella, both of whom both manufacture and install the windows. The third bid was from Goldfinch Brothers in Everett, WA, a 105 year old company run by the same family now in the 5th generation. We went with Goldfinch Brothers and the Milgard Ultra windows because: 1. A friend highly recommended the Goldfinch Brothers. 2. A contractor friend recommended the Milgard windows, vouching for their lifetime warranty on windows and labor (Milgard had just replaced his windows--including labor--decades after originally installed). 3. The bid was the lowest by 25-50%. We researched window frame materials and went with the fiberglass. We had excellent service from all three companies that put in bids with lots of info to use for comparisons. The installers from Goldfinch were outstanding. All were long time employees of the company with decades of experience. They worked very hard, cared for the house and cleaned up well. They problem solved a couple of unique window frame issues. We were very pleased.

Rated 2 out of 5 by from Poor Quality Unable to lock brand new Ultra French door after having it professionally installed. Installation crew can't fix faulty mechanism. I waited five weeks for Milgard service to come (unable to lock door entire time while waiting for service call). Finally they came and fixed it, but five weeks to fix a problem on a brand new door, defective from the factory, seems unreasonable. Other quality and design problems: 1) blade seal around periphery of door folds over when door is being closed. I had to "retrain" the seal - it took several hours of tedious work. 2) It's necessary to pull inward very hard on door handle when trying to latch door - very annoying. Service guy can't fix - says there is no adjustment to overcome this (design) problem. As a result, found door wide open on a couple occasions because person who last closed door had not pulled inward hard enough on door handle to latch it - it then spontaneously popped open later on. 3) The handle finish is rough to the touch - does not convey quality. The door mechanism and seals are inferior in my opinion and factory quality control appears lacking.

Rated 3 out of 5 by from Look pretty good. Extremely poor craftsmanship. I ordered sliding window from ultra series for my bathroom, as an experiment, to see if I want to use this series around my house. Right now I am disappointed in the quality of the craftsmanship, however, overall appearance is quite nice. WO#396201.00 SO#2500054.014 Issues I found: 1. Silicone and glue is all over the place. Glass, frame, top, bottom. I spend half an hour cleaning it. Weather strip has silicon over it as well, it does not close gap properly anymore. 2. Plastic gazing beads at the bottom and not properly inserted and have gaps. No way to snap them in properly, since frame was not glued straight. 2. Window is not plumb. Panels have gaps, you can clearly see it was not inserted properly, the middle of the frame has 1/8 bow outward. 3. Roller marks between glass. I ordered etched glass, and it has vertical and horizontal 1 inch marks from some sort of roller. They are between the glass, so there is no way to clean it. 4. Sliding window does not slide well. Rollers are very cheap plastic wheels and it is extremely hard to roll. You have to use both of your hands and push with your whole body. 5. Wood jambs are poorly painted, in addition some paint was simply sanded. I have patches of sanded paint that I have to pain over. No point ordering pre-painted.

Rated 5 out of 5 by from Nice windows Nice product. easy to install. Would like to see fold away nail fins, as that would make them easier to handle. One negative, the windows were well packaged, but upon removal of the packaging, i noticed the glass was filthy with rag wiped smears. I purchase a lot of windows and never had that in the past. I expect some sticker residue, but these were really bad.

Rated 3 out of 5 by from Windows perform good Fiberglass holds up better than Vinyl. The cons are that the windows are very thick, and the color fades over time. Get anodized aluminum or wood depending on the style of your home.

Rated 1 out of 5 by from Big problems with Milgard! We purchased 11 Milgard all fiberglass windows through Home Depot. The first problem arose when the order arrived from Milgard. 10 of the windows were correct---the last, was completely different than what we ordered. We sent it back and have been waiting for weeks for the replacement. It was supposed to have arrived today---but Home Depot just informed me that Milgard hasn't sent it out yet and it will take an additional week. Meanwhile, we're in the midst of a construction project that has been jammed up because of the missing window. If that was the worst of the problems it would be O.K.---- but it's not. Two of the single hung windows are literally falling apart. (and I imagine the other two single hung ones we ordered will soon follow) The windows were installed two days ago. The very first time we tried to open them the bar attached to the side of the windows to make them slide up and down (a really poor design!) just fell out. Trying to close them that night the upper part of the bottom sill (where the locking mechanism is) cracked because the window was out of alignment without the slide bar. I've written an email to Milgard but they have not responded. Incredibly shoddy windows---and apparently equally as shoddy customer service. I'll try going in to Home Depot to talk to their window department. The bottom sash's of these windows need to be replaced.

Rated 5 out of 5 by from Excellent Large Living Room Casement Window In August 2019 we had a large Ultra casement window replace our original wood casement window in our living room. The new window with the new low-e glass is beautiful, offers excellent sunlight control and well made. This window has definitely made our home more enjoyable and attractive. The installation which is as important as the window hardware was conducted by Best Choice Home Improvements of Renton WA in a very competent manner with craftsmanship matching the Ultra window. Milgard produces an excellent window.

Rated 2 out of 5 by from A design flaw This door is your three panel design. With the screen installed, one can not utilize the extra width of opening both doors because the screen covers one side or the other of the doors. Your design does not allow you to move the screen out of the entrance yet there is a tract for the screen to run on. However there is a brace that keeps the screen from moving out of the way. The locking mechanism on the main door has bind when trying to unlock it.

Rated 3 out of 5 by from Good or average windows We replaced 20 plus windows, single hung sliders and big sliders. Windows so far (1 month) have boon okay but the screens are the worst screen I have seen on any window, including contractor grade! I have service scheduled for tomorrow will update if necessary.

Rated 1 out of 5 by from Do not buy I bought single hung windows as well as sliders and awnings. The single hung are s poorly made they have sagged so now I'm struggling to put trim around them. I have complained before but they always blame installation rather than admitting their products are awful. If you purchase windows you will be calling customer service which has a normal wait time of 20 to 30 minutes which speaks volumes itself. Also all units were delivered with dents and chips since they don't want to carefully pack the units.

Rated 1 out of 5 by from Terrible Customer Service Getting in touch with Milgard is a nightmare. No one calls back, phone calls get dropped, when you do speak with someone, they don't follow through. Incredibly frustrating.

Rated 5 out of 5 by from New face lift for my house! I love the new windows and customized beautiful front door. We get so many compliments. My home looks newer and fresher and feels cooler too. The only thing that I was disappointed was that my front door is a little smaller than normal but its gorgeous.

Rated 4 out of 5 by from Attractive, seems to be well made This window was installed yesterday and the sliding window on each side is "very" difficult to slide back and forth. Seems to be hung up on the felt strip. Once the windows are closed, it is difficult to open.
