On Star Windows & Doors

That is our 2nd time working with this company .Very professional service. Comparable price.
Vlad always answers your questions in professional way. The new windows and doors looks fantastic.
We will definitely be recommending this company.

I hire this company to replace some windows in my home. Most were retrofit not brick-to-brick. Windows looked good when installed but a couple of them didn't close easily. Now that the cold is here I have noticed condensation building on a couple of them. They don't seem as well insulated as advertised. The installers showed up a few hours late as well.

My front window warped and would not close. My expectation was that the entire window plus the 2 adjoining windows needed to be replaced. Vlad came to measure for the new install and told me he could repair the window for a quarter of the cost. He came back a week later for the repair and the window now works like new. Definitely a company you can trust!

The windows are amazing, the crew is friendly and professional. I can only recommend them. Thank you Jim.

Amazing job at good prices! Very happy with our new door and two windows. On star windows and doors did a fantastic job on time and as promised. Great service, they are quick to reply and are very helpful when we had questions. Highly recommended to family and friends.

Over the years I have now ordered 2 doors and 8 windows from Vlad and his team.
Vlad is highly responsive, always returning calls, and the product and workmanship is always excellent. I have recommended Vlad to many friends and family and will continue to do so.

We are very pleased with the work that On Start has done.
We had a few companies to bid for the job - entire house windows, entry and backyard doors. We went with On Start and never regret. Sales fully explained in detail to us the whole process, benefits and options, timeline, he never pushed us, was acting like an independent consultant who works for us.
The installation crew in combination of 5 people came to install the windows and doors. They did an immaculate and clean job. All extras were done w/o questions. They never stopped, job was completed within one day. Next day sales stop by to check the job, nice customer service!
We are fully satisfied with quality of the windows and doors. Entire process from beginning to end is just what you expect from professionals, definitely recommend On Star.

Such a nice good- looking door. Good quality. Fast and reliable work. The installer was just a charm and Vadym is very nice and respectful. Definitely recommend to everyone to use this company.

Very detail oriented. Clean...and ultimately focused on client satisfaction. Doors slide well and lock with ease.

The installation was scheduled and the installation team arrived in the scheduled window, called ahead to confirm their arrival.

All my old materials were taken away and the crew left the area spotless.

This is my second time using this company and will continue to do so and bring recommendations to all my clients

We understand that covid 19 has caused delays on many products being delayed, however , we could not be happier with the high level of customer service and the beautiful doors that Vlad and his team installed for us. Vlad is a true professional , he provides quality windows and doors at an honest and fair price . We absolutely did not mind waiting longer than planned for your doors to arrive because they were well worth the wait . We have done many renovations in our home and dealing with Vlad has by far been the most positive experience we have had to date. Anyone would be lucky to have Vlad and his team install their windows and doors . We will always be loyal customer and definitely recommend him to all of our family and friends .
