Yoni and his team did an excellent job installing windows for my whole house (13+). After getting bids from many companies, not only did Frontline prove to be the most affordable quote, but they also provided high quality Milguard windows that look great and are night and day better than my previous double hung windows. I appreciate Yoni's honesty, dedication to delivering on his promises, and follow through. Noel and his crew did a fantastic job with the installation and I highly recommend Frontline for anyone looking to get quality product, installed with great care, at an affordable price. read more

This place does not do good business. Their communications are atrocious. I called twice and wrote an email twice with no response. I gave them ample time to respond, but after two weeks, I gave up trying to give them business. read more

Frontline Windows & More - My new backyard sliding window. - Windows Installation Near Me - Chatsworth, California

I contacted Frontline Windows because I needed an estimate to replace my windows in my house. Yoni came to my home and was a true professional. He comes with years of experience and was able to share varying options. I am remodeling my house so budget was a big deal for me and Yoni gave me a few options.  I ended up going with black windows (inside and outside). His estimate came timely and was very competitive. I would highly recommend Yoni and Frontline Windows if you are looking for an honest assessment of your windows and doors who really know his business. Thank you Yoni and the team at Frontline Windows read more

I would not recommend Frontline Windows & More for windows. I hired them to install windows in my house, the windows are still under warranty and they are turning colors. I called for weeks and the "receptionist" would take a message and say someone will call me back. That did not happened. I finally had to be creative and found a number to someone with the company named Yoni at 818-231-9707. I spoke to him days ago and he said that he will put in the claim. I sent him a reminder the next day because he said that I should receive an email when he puts in the claim. I called Ply Gem this morning and they do not have any request in their system for my claim. Frontline is good for contacting you to give you a quote and install windows. When it comes to standing by their products/service they are seriously lacking. Buyer beware. read more

I would recommend Frontline Windows to my friends & neighbors. I had a very good experience with Yoni & his installation assistants. Yoni replied to my multiple (17) emails within a day or 2 over a period of 2 months. I am very detailed oriented so I made sure the estimate details were all correct to make the final order. I ordered 10 windows and 1 sliding glass door. They all work smoothly and the installers took their time to do it right. The windows look great and made a big difference in lowering the sound of the pre-school sharing the backyard fence and lowering the heat a little. The manufacture forgot to include 1 screen so they shipped it out within 2 weeks. See below for before & after photos.Top photo read more

Customers be aware!! I hired these people to install new windows throughout my home a few years back and now one of the windows won't open or close. I've been calling them for the past 6 weeks and all I get is the run around. Finally...I spoke with someone today and again, he was trying to pass the blame on someone else. I am going to report them to the Better Business Bureau. The last thing I want is that this happens to someone else too. They don't stand behind the products they sell!!! read more

Thank you, Frontline Windows and More for our new windows and slider. We love the look! The initial call and quote was easy thanks to Fred and his presentation of information. Great price and quality. We appreciate that Frontline quickly sent a repairman to patch couple of leftover holes in the frame of the slider after installation. Overall, we are satisfied :) - Jenna Walter read more

I will never ever use this vendor ever again. We ordered a specific type of window and they sent us the wrong ones putting us out 700$...when we tried to dispute it they fought back & based on their mistake we are now out 700$. I have photos of my invoices and texts to prove their mistake & i will definitely never ever use them again or recommend them to anyone. Be careful when ordering from this store they have ZERO INTEGRITY. read more

I needed my old windows replaced for few years now so I start searching for a company to do it for me .I got few quotes and I ended up going with frontline windows.they gave me the best price and Yoni was so very helpful with choosing the windows .took some time to revive the windows from the manufacture but one we did they installed it the next day. Very professional company! I have already referred them one of my friends . read more

We're quite pleased with the large job Frontline did with our house, but it wasn't without a few hiccups along the way. Regardless, we'd possibly reach out to them again and recommend them to others. We moved into a house with outdated windows from the '80s and were ready to replace them. Ron was quite helpful, although a bit slow in replying to emails. He would send us updated invoices each time we had a question, informed us of egress (exit) codes so that our new windows would be up to par with city standards, and was an overall pleasant individual to work with over email and the phone. They installed four windows on a second floor, a sliding glass door, and six windows on the ground floor. Four installers showed up early and finished everything in one day. The windows looks amazing and made our house look brand new. The sliding glass door was especially awesome. A few downsides - upon removing the old windows and installing new ones, there were quite a few scuffs and gouges on our windowsills. Additionally, a window facing the backyard was especially difficult to remove, so they had to shatter it. Fine, but days later, we found large chunks of glass in the grass. My son is still a baby, but it worried us tremendously. Finally, two of the second story windows were not the windows we ordered on the invoice that we signed and emailed back to the office. I called the office and spoke with a sales rep, who admitted that they didn't double check the invoice thoroughly and placed an order for windows based what he remembered from our email thread. I could live with one window the way it was, but needed the other window to be replaced. We went back and forth peaceable. At first, he said he could replace the one window with a $100 discount, bringing it to $300, but I insisted I shouldn't have to pay for a mistake on their part. He said he'd get back to me and there was no communication for several weeks. Then, I unexpectedly received a call asking if I was available that day for a window replacement. I made sure I wasn't going to be charged for it, and they confirmed it would be free due to the error. New window looks great (yes, some scuffs and gouges on the windowsill that we can live with) and all is well! read more

We had 11 windows that were original to the house. The wood was decaying, the windows were hazy and were in need of an upgrade. We saw an ad in a local flyer about Frontline and decided ask them for a quote. It was the best decision we ever made. Fred from Frontline came over, and promptly took measurements of all windows and even suggested that we should take two windows in our master bedroom that were separated by a mullion and make it into one big window. The aesthetics of the job and windows were talked about in detail until I approved of what I wanted. Fred also demonstrated the difference between standard windows and double and triple pane windows that have low e and gases to absorb external heat and keep the house cool. All in all, the initial process was informative and Fred listened and allowed us to voice any and all concerns. The price of the windows and installation was well within our budget and Fred made us an offer we couldn't refuse. The windows took about 2 weeks to make and the installation team took about 7 hours to install all 10 windows, complete with outside trim. They did a great job and dramatically changed the look of the house. I appreciate Frontline and look forward to doing business with them in the future. read more

I have done business with Yoni for many years and he is always a pleasure to work with. The quality of the windows is great and the prices are very reasonable and always lower than other competitors. He keeps an open communication with you and there are no surprises. His crew is great and they have always done a great job. I strongly recommend calling Yoni if you need to replace any windows/sliding doors. You won't be disappointed. read more

I don't care how their install team is....all I know is that the salesman who came to give us an estimate was so rude I almost just cancelled the entire estimation process. I literally felt like someone was coming into our home to disrespect us. If a company doesn't understand the concept that the face of their business is everything/first impressions are everything then why would I want to work with that business. Not to mention I just read all the other reviews and it seems like I'm not the only person who felt this. Get with it Frontline! He didn't explain any of the materials. He didn't explain any options. We tried asking him about different options and he acted like he didn't even know, but then asked us to make a decision on the material. I also asked him how thick the frames were and he told me if you like the estimate you can just come to the showroom. read more

Richard was very professional and personable and punctual today. He gave me a quote for 4 windows and break for an energy efficient upgrade if I decide to go ahead with the job, fair enough. I've been wanting to do this a while and finally today is the day! I'm excite to get new windows for my three bedrooms and bath! read more

We ordered 2 doors, 1 slider and 3 windows from Frontline. We liked our salesperson Richard (flexible , upfront/honest) however execution of the Windows/doors install didn't go as planned. Pros: lots of crew members on install day, clean, respectful , on time. Install can happen on weekends (you have to request it the lady at the office doesn't offer it up front). Doors and windows are good quality . Love the slider we ordered - huge difference in insulation for the house . Cons: doors don't come painted , you have to request new frames with the doors or they won't order and install it( this happened with us, it was rectified after I pointed it out, Richard came right over ). Windows don't come with the frames. The type of doors ordered (with windows) had almost paint resistant areas on it - such a pain and $$ to have painted. Install damaged paint externally and internally in the house. Overall I liked the product but the install and pain of painting / errors during install have me on the fence about using them again. read more

I just had 3 of my windows replaced with the Ply Gem product. They are triple pane and energy efficient. The product is fantastic. Frontline did an amazing job with the installation. Very professional. I would highly recommend this company for your windows or door insulationa Robert A. Ferkle read more

Very professional company who believes in value and integrity from the sales consultant to the installers and everyone in between. Very happy with our new windows. Will definitely give them my business in the future. Highly recommended read more

Awesome experience from begging to end. I highly recommend them if you're looking to replace your windows.

Quality product and windows but the communication was awful and it took forever to actually get everything installed and working. I was shocked they never offered a discount for all that we went through. I was in between 3 and 4 stars since the windows are very nice and the price was right but the customer service and lead time on windows and then missing parts was just awful. read more

I had a salesman from Frontline come out to give me a quote for new windows in our home. To make a long story short, this was the most unpleasant sales experience I've ever had. The salesman was rude and pushy, and refused to leave after I repeatedly told him I wanted a day to make a decision. As I prefer doing business with straightforward and professional people, I will not be going back to this company for any reason. read more

The owner of this company came out personally and helped me decide the style of windows I wanted. Having shopped around quite a bit, this company is EXTREMELY competitive with the prices! The install team is here right now, and the are efficient, polite, and wonderful craftsman. Could not have dreamed of a better experience. I will HIGHLY RECOMMEND this company to everyone. Thanks Frontline, Christopher Striepeke read more

We couldn't be happier with our two windows that were installed by Frontline. We are in the middle of remodeling our kitchen and on a time line to have them installed before plaster & painting. Yoni kept us in mind when he had a cancellation and was able to slot us in sooner. The crew did the job were professional and wasted no time! The windows are quality, glazed, and lovely! The fit and caulking job is seamless. The price including installation was the best! I was overwhelmed with window reps blowing up my phone. Some of the quotes I received were literally insane and more than 200% higher than Frontline. There are a lot of scam window companies out there. Frontline is not one of them! read more

We spent six months getting estimate after estimate for replacement windows. Most of these estimators were as sleazy as a used car salesman. We finally found this little shop that answered all our questions in a straight-forward, patient manner. We ignored their "specials" and various discounts and got right to the chase: will you beat our best bid? They did and we ended up with gorgeous Milgard windows and a four panel slider. So nice. The best part though was their installers. Four guys came out and did the job in one day in a very professional manner. The fit and finish are perfect as was their cleanup. It is obvious that this is a shop that wants to grow their business by giving first rate service. So do your homework, know what you want, get some bids and then give these guys a call. read more

At first, I was extremely pleased with this company when they came and replaced all my windows on my house. I was so happy I referred them to others. A year later, I had a window accidentally shatter by the gardener, and I called and asked them for an estimate for a replacement. They said they would pull up the order and call me back that day. Never heard from them. I called them back the next day, and they told me they would get back to me. Still hadn't heard from them. I called back the next day and spoke to someone again. Same thing. It's been a month and I have not heard from them. Sounds like a company that will take your money and then after that, they don't care what happens next (even if I was willing to pay for the replacement window!). Shame on them - I will no longer refer them to others. read more

Wow what good service. Frontline installed all new Windows for my home in June of 2014. This past Saturday two of my windows leaked water in the driving rain. I called in a panic, so worried they would tell me sorry been 4 years now, to bad. They immediately made appointment for this Wednesday to fix. The two guys they sent out were fantastic. They scraped out old caulking on the two leaking Windows, and re-sealed with poly mastic. Great job, the best follow up and service. Will recommend Frontline Windows to everyone. 5 stars from me. They stand behind there work, even 4 years later. read more

Frontline installed two beautiful windows at a very affordable price. We wish we could have installed more.

I had 4 windows and a sliding door installed on Saturday. When I met with Richard last month he was very professional and answered all my questions. After he did the estimates he was able to beat the other 2 estimates I had from other companies. When the installers arrived on Saturday, they immedityly went to work and removed all my old windows. It took about 3 hours for the whole installation and they look great. They were very professional and they took great care in installing and cleaning up. read more

I recently had all the windows (19) in our home replaced with Plygem windows from Frontline. We had many contractors come and give us quotes. Frontline was our choice not just because of price but also the clear and straight forward way they communicated with us. We had several pushy sales people from other companies that left a bad taste but Yoni from Frontline was patient and honest with us. The windows are fantastic! They keep our home cool and quiet. The installers did a great job of sealing around all the windows, it was a very professional job. I would surely recommend Frontline Windows to anyone. read more

We had 12 windows replaced by Frontline Windows and they were amazing! They had a whole team come in and it was done within a few hours. They even cut and reframed a window to city code. Everything passed city inspection. The kitchen window was defective and it cracked. Frontline replaced it for free after the window manufacturer wouldn't even check it out. That's great customer service! I recommended them to my friend and they had all their windows replaced through them. Excellent company, from the salesman to the workers. Thank you Frontline. read more

We had all our windows replaced in our condo and are very pleased with the result. The whole process was very smooth. Communication was great from start to finish and everyone we dealt with was professional and courteous. On the day of the install, we were impressed with the speed in which the job was completed! Roughly less than 6 hours to replace all windows. They did a great job and cleaned up well after themselves. Overall we thoroughly recommend this company to others! read more

I had 3 sliding doors and 10 windows replaced at my home in Diamond Bar last week. The service and workmanship are excellent and professional.

I would give them 10 stars if I could. Customers Victoria and Winston Ramos. read more

Frontline handled the installation of 7 triple pane windows on my property a couple years ago. Overall, I have been happy with the results and service. Richard came over and gave me an estimate for the preferred windows and labor. He even helped recommend just what type would be best for my situation. One of the windows now appears to have been a tad more hastily installed than the others, however, and a little cracking has since appeared where the screws are inside the wall. Merely cosmetic, of course, but avoidable at first all the same. I wouldn't mind considering Frontline for my future window needs. read more
