Dian Qi
Andrew came by to check out our broken windows and was super friendly, professional, and communicative. We're looking forward to getting our windows replaced and are very happy so far to have found Pella Windows & Doors!
Scarlett Flores
We’re developers in the Los Angeles area, and Vilma was a total pro. She made sure we got exactly what we needed at a great price—and on a tight timeline. Wintorium has quickly become our go-to for all our windows and doors.
Miguel Sanchez
I recently replaced all the windows in my Los Angeles home, and Raymond from Wintorium made everything easy. He was friendly and super knowledgeable. The installation team did an amazing job, and the end result totally transformed our house

If I could give these shady guys 0 stars I would. Homeowners beware! Not only was the installer’s work unprofessional and lousy, they left the house a mess without cleaning, leaving debris around the window and floors. Worst of all they damaged the molding and frame of the windows as you can see in the attached pictures. The sliding door was measured almost 2.5 inches short, there was empty space on the top section when they finished installation per the pictures.
When we called and asked for the Manager to explain the problems and request fixing, they refused to take responsibility! We told them we will not pay the final balance until the installation is complete and they fix the molding which they damaged, which is warranted per the contract and under CA law. The response from John or David (Owner) was threatening, yelling and saying that if the balance is not paid, they will file a lien against the property. Given we didn’t trust them at that point and didn’t want them to make it worse, we were forced to fix it ourselves! I do not recommend anyone use these losers for your window work!
Monica Crews
Great service, price, and product. I had this company give me the best price and also the best product. The installation crew was on time, professional, and hard working. They first took their time to lay down rugs and put plastic over everything that might get dirty. I was impressed with their work ethic and they fully cleaned up everything when they where finished. The quality of work was great. We love our new windows. I highly recommend this company to install new windows. From what I experienced, their price could not be beat and they use quality windows.
