Hovik came in, priced things out, we did comparison shopping and not only did they offer the best door and price, they also executed the install flawlessly. My HOA was amazed. William and Jose the installers were excellent and knew what they were doing. This is a pro shop, I vetted other places, this place is head and shoulder above the rest. Thanks Hovik and Team!

We recently had all the windows in our home replaced, and I couldn’t be happier with the entire experience. From the initial consultation to the final installation, the team was professional, knowledgeable, and incredibly easy to work with. They took the time to answer all of our questions, explained our options clearly, and helped us choose the best windows for our home and budget.

The installation crew arrived on time, worked efficiently, and treated our home with care and respect. They made sure everything was properly sealed, cleaned up thoroughly after the job, and walked us through the finished work to ensure we were completely satisfied.

Our new windows look amazing and have already made a noticeable difference in comfort and energy efficiency. The quality of the workmanship truly exceeded our expectations.

I highly recommend this company to anyone looking for reliable, professional window installation. Five stars all the way!

We replaced our windows and doors with this company, and unfortunately, I am very unhappy with the service. During installation, the installer damaged our patio doors and screens, and the patio door handles are loose. We were told someone would come back to fix these issues, but it has already been a couple of months, and no one has shown up.

My main concern, however, is our kitchen door. Our original kitchen door opened from left to right, but they ordered and installed it to open from right to left. Because of this mistake, the door now hits our refrigerator. Hovik was the person who ordered the door and acknowledged the issue. He told us he would take care of it and at least install a door stop so it wouldn’t hit the refrigerator, but to this day, nothing has been done.

Additionally, we were planning to order another window. Hovik told us he had one in stock and said he would give it to us for free so we wouldn’t change the door. However, the window he provided was damaged and of very poor quality—the glass has scratches, and the screen does not match the screens on our other windows. It appears to be a previously returned window that someone else had damaged.

On top of that, we were told this window would not cost us anything, but later the invoice was changed and sent to my husband with almost a thousand dollars added to the total.

Because of this experience, I do not recommend this company. A friend of mine and my cousin both asked for their information, and I did not recommend them.

I recently had the opportunity to work with Frontier Windows and Doors, and they exceeded my expectations. After interviewing seven different vendors, Frontier distinguished themselves through their extensive product knowledge and expertise in installation.

All aspects of the project were completed exactly as outlined during the initial estimate. The order was properly confirmed, delivered on schedule, and installed within the stated four- to six-week lead time. The quality of the windows and doors is outstanding, and the final result greatly enhanced the appearance of the property.

I highly recommend Frontier Windows and Doors to anyone seeking a knowledgeable, reliable, and professional window and door company.

Excellent, excellent company.

They gave me a great price on replacing an oversized sliding door. Arthur, my sales person ensured the sliding door matched the specific colors I had on my existing windows.

When it came to dealing with the office, Joanna is a super star, extremely professional and well organized.

I was impressed with the skill of the workers. I did not expect them to do custom trim work to match my existing moulding. Highly recommend this company!!!

We worked with John about a year ago and the quality was the best we could have wished for. The windows look as great as on the first day and the speed of installation was phenomenal. John himself was one of the kindest and forthcoming men we ever did business with. Thanks and hope to do our next project with Frontier windows

John and his team were fantastic. They arrived on time each day. When they finished up at the end of the day, the job site was cleaned up, both inside and outside. John explained the process as they went along and answered any and all questions.
We had all windows (25) and 2 sliders replaced in two and a half days.
Frontier Windows in Canoga Park prices were competitive with local shops. As for the product, the house seems cooler and everything looks wonderful.
Thank you Frontier Windows!

Company did a great job with changing out three windows in my son's room. House was built in 1893 and the options for their windows blend perfectly. Thank you to Frontier Windows for the initial evaluation and follow up to set up the job. On installation day John arrived on time, were very professional, friendly, and clean. The windows work amazing, you can feel the difference for heating/cooling efficiency. We'll definitely be using them again for changing future windows.

We had an extremely disappointing experience with Frontier Windows. We signed a contract and made a deposit of $1,000 on February 25, 2024, with the expectation that work on our windows would commence on March 20, 2024, and be completed by April 24, 2024. The project was for a building in Glendale, almost 100 windows. However, after more than five months, there was no progress in obtaining the necessary permits. Despite repeated attempts to get updates, we were met with excuses and delays. This lack of professionalism and accountability from owner “John” breaching the contract forced us to find another company. Not only did they fail to deliver on their promises, but they also left us in a difficult position of having to start the process all over again. We had hoped for a smooth and efficient process, but unfortunately, this was not the case. We are now seeking a refund of our deposit which he refused to give back and looking for a reliable contractor to complete the work. We do not recommend this company for any project that requires timely and responsible management. This experience has been a significant setback for our community, and we urge others to be cautious before hiring them.

Frontier recently replaced all the windows in our apartment, and we're thrilled with how everything went. John was incredibly responsive from start to finish. He came by, measured everything, explained our options clearly, and gave us a quote on the spot. He even took care of our HOA's requirements without us having to ask. The installation team was equally professional. They covered our floors and furniture, and cleaned up thoroughly afterward. The whole process, from removal to replacement, took less than a day. We highly recommend Frontier for their excellent service.

Choosing Frontier Windows and Doors for my house remodel was a standout decision. After checking out five different places, Frontier clearly stood out for their great customer service and competitive pricing. John guided me through the entire process, and our rapport grew to friendship due to the positive experience. If you're considering new windows for your home, Frontier is hands down the best choice.

Excellent work by this group of people. They had the best quote in the Valley and Rose at the office was quick in getting me the installation appointment once my windows arrived. Eduardo and his team were super efficient and did a wonderful job installing my windows including a garden window which was complicated but they got it done and left my place spotless!
