Style Line® Series Radius Window is rated 4.4 out of 5 by 576.
Rated 5 out of 5 by from Easy to open and close look beautiful Had new vinyl windows installed in our 1978 mobile home and we could not be happier. The home feels much tighter and warmer. Love these windows. Great quality at an affordable price.

Rated 2 out of 5 by from Very disappointed If I had to build another house, definitely won’t use The Home Depot/Milgard Windows. It took two months to get all my Windows, but one, done. Product is very fragile, windows came broken to me, it was such a nightmare with these guys. Hope everyone could learn from my experience. Still waiting for another window that came with the wrong color. My windows mech came down size so I was told to use double contact tape to keep it in place. Very very disappointed.

Rated 5 out of 5 by from New Window Install In the past month we have had 4 Milgard Windows installed in our home. The installation crew arrived on time, installed the windows and cleaned up their mess. What else could you ask for? We are very pleased with the results.

Rated 4 out of 5 by from Beautifully simple Great windows! Easy to use. One came broken and no one has come to fix it yet and it’s been 3 weeks. Probably would have given 5 stars but waiting isn’t fun.

Rated 5 out of 5 by from Love my windows! I had 17 windows replaced and really capped off my home remodel. They look great, work great and it is now more quiet compared to my old original windows. They were the best priced and have a lifetime warranty.

Rated 5 out of 5 by from Good Service Several problems were caused by our building contractor when installing our Milgard French Doors and Style Line Windows that the contractor refused to fix. We contacted Milgard and their technician resolved all the issues in very professional manner. Great company.

Rated 5 out of 5 by from Great track record We've had Milgard patio sliding doors for several years which has led us to use Milgard replacement windows throughout our home. Top rated product!

Rated 4 out of 5 by from Great Windows I love that Milgard honors their warranty. As a realtor I see Milgard taking care of failed window panes more than once. One thing less to worry about when selling a home.

Rated 5 out of 5 by from Excellent Upgrade One of the best upgrades made for a household. Lowered the temperature selection on the thermostat for Winter Season by (5) five degrees or more. Keeps interior temperature’(s) constant. Day or Night. Installed (8) Eight Style Line Series Horizontal Sliders Windows, (3) Three Style Line Opaque Bathroom Slider Windows and (1) One Style Line Sliding Door. Also, (1) One Style Line Series Radius Window. The Style Line Series Sliding Door was installed on a stucco exterior wall. Some patch and repair was required along with prime and paint. And the interior trim for the interior dry wall needed finish painting. The Style Line Series Radius Window was installed on exterior wood siding and needed prime and painting. Also, the interior trim and window sill needed prime and paint. It was all done professionally. The contractor recommended a sub-contractor for patch and repair for the exterior stucco. The painting was done by a friend that is a professional painter by trade. Selected the Queen Ann Style detail on all the windows and sliding door. An excellent choice and upgrade.

Rated 5 out of 5 by from Very happy Bought 3 windows to replace Milgard windows in which the plastic spacers in the hinges had dried out and crumbled. There were no replacement parts since they were of an older style. These new ones are lovely in the light that comes in and the ability to allow air to flow.

Rated 5 out of 5 by from Perfect in every way! The door and windows are not only beautiful; they have already enhanced the livability of this house, in that the noise of the freeway behind the house is now practically unnoticeable!

Rated 5 out of 5 by from So Far So Good Our window s were only installed a couple weeks ago, but we can already tell the difference. They open easily and the amount of heat/cold Coming through them has diminished substantially.

Rated 5 out of 5 by from Great I bought these windows before the coldest month this year and so glad I got them they make a big difference. Warmer no more condensation.

Rated 3 out of 5 by from Time will tell!!! We had a couple of windows where the seal was broken. The main window inconcern have lots of something inside and it looks horrible and just so happens it was towards our view of Tacoma. So I decided to not just change the glass but have the whole window changed along with a sliding glass door I really like the security details of the Tuscany door with the built-in blinds my wife and I are both in love with that. Because we're facing due west I went with the low e max code sunglass, to help cut down the UV rays and keep the house cooler and warmer. But like my title review says time will tell the windows it came out where milgard and the seal is broken but because I'm not the original owner I didn't have the warranty. Well now I have the warranty on these but we hope the windows hold up.

Rated 5 out of 5 by from Beautiful windows! We bought new windows for our main floor, 2 picture and 5 slider, and they are beautiful, open and close perfectly and no cold air drafts! Totally recommend them! Aslo for an install in the Kelowna BC area we recommend Nagy Bros, they went above and beyond with their service.

Rated 5 out of 5 by from They are beautiful Brite Glass of reno installed our windows and we couldn’t be happy. They are beautiful and the difference they make with the noise and the energy is amazing.

Rated 1 out of 5 by from Worst windows Big mistake to install these windows I bought these windows for my house and spend $15000 but these windows start leaking with the first rain and Milgard don't want to stand behind their Life Time Warranty. So Don't listen to sales rep about how good the quality of these windows. You will be regret it later.

Rated 5 out of 5 by from great product new windows were installed over the last week and so far we have noticed a decrease in road noise, heat/cold inside the house. We hope the product lasts and the company stands behind their product if we ever have an issue. But so far the product seems amazing!

Rated 3 out of 5 by from Installation not guaranteed Bought 4 Styleline Vinyl Windows w/ Grids and 2 Vinyl Sliders with Sculptured Grids in 2000. I recently remodeled a bathroom only to find out that 3 windows had been leaking for quite sometime due to poor installation by DP Door Co, Rancho Cucamonga. Called Milgard to report issue. They were of no help and stated Milgard is not responsible for installation even though it was a certified company recommended by Milgard. NO NOT INSTALL RETROFIT WINDOWS. Go with new construction. Other than the leaks they are a good product.

Rated 5 out of 5 by from Beautiful and stays clean I have replaced about 24 windows in my house and my friends continue to say WOW.
