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.

Rated 1 out of 5 by from Screens were sub-standard We purchased Thermal Break Aluminum Windows as replacements. The screens that came with them were so flimsy and poorly designed that they were unusable. When our local dealer complained to Milgard, he was brushed off. The dealer had to fabricate new screens in his shop, at his cost. Milgard came nowhere near living up to its reputation.

Rated 5 out of 5 by from Replacement windows We replaced all of our windows with Milgard 14 years ago. They were gray with white grids in double panes. We have been satisfied with them in sunny California. About a year ago shading started appearing around the grids. We contacted Milgard and today Leo and Nick arrived to replace those windows that were affected. Great men!! They were friendly, efficient, and even replaced a handle while they were here. No wasted time, in and out quickly. All under the lifetime guarantee. Thank you, Milgard!

Rated 1 out of 5 by from Terrible manufactring I bought two Aluminum Sliding windows. One came with damaged frame and the other came with wrong sliding door. They were both ordered complete assembled doors but they came unassembled. The rubber gasket on the fixed panel was jammed inside the stile and there were screw holes on the fixed panel. The wheels were on the wrong end of the panel and the lock strike is installed in reverse direction. The whole this was a mess and when I called Milgard I was told Home Depot was suppose to put the door together. I called Home Depot and they say they never put the doors together. I will dispute my credit card charges on one of the doors and let Milgard and Home Depot fight it. I still need Milgard to come and fix the Lock and take care of the squeeking sound that come from the slider when opening and closing. I had to pay $500 extra to my contractor to put the door together and fix the rubber gasket. By the way I sent a Service Request four days ago so far no one called.

Rated 3 out of 5 by from Good windows, poor customer service We have our windows and sliding glass door installed in April, 2018. We ordered aluminum windows in a dark bronze color replacing nearly 60 year old builders grade aluminum windows. The price is good competitive to the market. Pros. We like the dark bronze finish, the construction on both the windows and door seem solid and long lasting (will outlive us, that's for sure) drafts we had from our home's original widows are gone and the noise reduction is noticeable. It's very quite in our house. Cons. The order was late and that slowed the remodel considerably. When they arrived, two of windows were incorrectly made and most of the rest were damaged in transit. Getting the order remade correctly and shipped without damage set our project even further back. Milgard refused to offer any refund for their problems. Also, they shipped the wrong kind of screws for the sliding glass door, round head screws instead of flat head and that is causing little dings in the door. There were a few little dings and scratches, but a we just decided to install them and live with the blemishes. Like the windows and door, not so happy with the Milgard's attention to details and service. A little touch up paint promised by our contractor to be provided by Milgard would be nice Would recommend with a note to pay attention to what is delivered.

Rated 1 out of 5 by from Horrible Warranty Our glass shattered with no impact and this series does not include a warranty for the glass. To replace the glass alone is $950.00 and Milgard will not stand behind their product. I will never use this brand again.

Rated 5 out of 5 by from Very impressed with the quality and appearance Installation just completed and my tenants are pleased with the new windows. They live on a busy street and traffic noise is reduced in the apartment.

Rated 4 out of 5 by from Clean Design We just had our windows put in today. We went with the thermal break aluminum as I was not convinced the vinyl in our heat would wear well. This is an older ranch and the style fits with the architecture. We are anxious to see how temperature is effected and if there is a notable difference in not hearing the outside noise. We wanted American made. My only negative would be the corners where the vertical,and horizontal frame pieces meet. Not bad, but not perfect.

Rated 2 out of 5 by from Nightmare entire house replacement It seems we paid 1st quality prices for 2nd & 3rd quality products. Entire house redo. There a few windows that did turn out beautiful, I think, as I'm exhausted inspecting and just don't want the stress of $$$$$ spent for defective/damaged goods that are special order and take weeks to receive and install. Along with either having the defective item installed (it yours!), getting ply board to cover the hole, or putting old window back in. I've been told the warranty is "wonderful", fingers crossed. One set doors. Lock will not work routinely and glass is scratched, it's a nightmare trying to lock. 2nd set. Glass was severely scratched for over a foot & we wouldn't allow install. Top solid pane on top of roof has multiple cracks and was installed w/o consent by installer. Told of defect after install (this is on both Milgard and installer) 2 windows the frames are scratched. Bay window one of the windows will not open. Door with built in shades, the shade panel is set off to one side between the glass so the door looks lopsided. Multiple screens bent, dinged, cut. Miscellaneous scratches on several "NEW" windows.

Rated 3 out of 5 by from Room for improvement Corners of nail-on sash need to be welded. Without special attention with flashing and caulking, these windows will leak. Windows and doors need to be shipped with something other than the sticky bubble wrap. Each door and window took about an hour to clean of the adhesive residue on the windows and sash. In some cases, I couldn't get it off. That stuff is awful.

Rated 5 out of 5 by from Great doors! The doors are as expected. Milgard does need to send all parts with deliveries, as we had one incidence when the rollers were missed in the delivery.

Rated 3 out of 5 by from Horrible warranty repair service I've had my Milgard windows for over 25 years. There have been very few problems until about 2 years ago three of the windows started to collect moisture. After making 13 calls, speaking to 4 different supervisors / managers, Milgard coming out seven times and nine servicemen, waiting for 7 months the warranty work on three windows has been completed.

Rated 1 out of 5 by from Horrible Lead Time........ So I only ordered 11 windows on April 11 2018 from Tri-Supply in Temple (Very Good Customer Service) and there was a 4 week lead time to receive the windows. It is 5-4-2018 which is less than a week away from the original 4 week lead time and now Milgard has told Tri-Supply that my windows will not ship out until June 8th!!! Unacceptable... I am building my home myself and cannot begin erecting the building until these 11 windows are delivered. I have a loan for this build in which now I am losing over 2 months off of my 9 month timeline that I have on this loan for construction. I would appreciate it if Milgard Management would contact me as I am spending $4600.00 on just 11 windows. This is completely UNACCEPTABLE..

Rated 1 out of 5 by from Service Request cannot submit All I want is to replace the cloudy glass. I filled out the request for service in the hopes of getting some help and it would not allow me to submit

Rated 3 out of 5 by from Adjustment challenge & un-anticipated flange I did not realize there would be a flange on the bottom of the window frames (assume used for manufacturing and shipping). After some trial I was able to key it off like an old style can opener. There is little or no adjustment of the panels in the frames. The latch on one window conflicted with the frame. I got it to function but the top and bottom sight line of the panels does not match on more than one within my order of six units. There was quite allot of factory sealant on the faces of the panels and frame. Perhaps a representative site visit is in order.

Rated 5 out of 5 by from Lifetime Warranty for Real!!! MILGARD replaced 10 panels of glass that were 25 years old, May of 2018. We are the original owners & still in shock, that MILGARD actually stands behind their “Full Lifetime Warranty.” And they will continue to honor the warranty as long as we own our home. I have never experienced anything like this, ever, without a glitch of somekind. All they asked is that the windows were clean to verify the double pain seals were blown. I had the windows cleaned the same day Milgard came by. And that was it! It could not have gone smoother. Still amazed!

Rated 4 out of 5 by from Warranty work The process to get the windows ordered and installed was a pain. I am the original owner and had to practically sell my soul to get the damaged windows replaced. Once they finally ordered the window everything went smoothly. Window was replaced today and it looks great, service people that came were great also. They also measured two other windows that need to be replaced . Barring any problems I think it was a good experience especially since they are a lifetime warranty and I didn’t have to pay anything.

Rated 1 out of 5 by from Zero Support or Replacement Parts on Brand New Doors Last year I purchased four aluminum sliding Thermal Break Doors. Three were delivered close to year end (last days of November 2017) and one was not (December 2017) because Milgard lost a glass panel of the fourth door. Milgard subsequently internally ordered a new door one month later in January of 2018 that was delivered in February of 2018. The problem is that in 2018 Milgard allegedly discontinued the production of the aluminum anodized door handles so now I have three new installed doors with aluminum anodized handles and the remaining uninstalled door with a black hande. All doors are on the same wall, one next to the other. Nobody at Milgard seems to care though the order for the four doors were placed at the same time and the delay on the delivery of the fourth door was a Milgard internal problem. It is incomprehensible that I have failed to obtained one set of anodized handles to complete my order and have to replace four doors again to get anodized handles with another brand because Milgard does not produce replacement handles for door delivered in November and January of 2018. The "value" turned out to be negative, worse than poor when you consider the additional costs I am incurring as a result of this change in design in the middle of delivering a purchase order. Bottom Line: Milgard does not stand behind the products they sell. I have been working with them for the last 3+ month at no avail. I can't even find these handles in ebay or the secondary market.

Rated 4 out of 5 by from Very Good Doors They have held up fairly well in a tough, salty environment. Other than a little rust on one latch there has been no oxidation. One door handle mount broke but Milgard replaced it for free. And, one door latch is a little stiff. The follow-on service from Milgard has been fantastic.
