There’s no denying the significant roles your doors and windows play to help make your home beautiful and comfortable. Zen Windows completely understands this. That is why we offer a solid lifetime warranty for both the material and labor of your door or window replacement. This warranty, which surpasses industry standards, will make sure that your investment is properly protected throughout their lifetime.

The Zen Guarantee

If possible, we want that the money you paid us to have the replacement doors or windows installed in your home to be the only investment you will ever have to incur as far as those replacements are concerned.   If problems arise, regardless of the issue, whether it’s a torn screen or a broken glass, we have your windows and doors covered. And more importantly, there will be no extra cost from your end.

We take pride in the fact that we promptly respond to warranty service calls, no matter how small or big the issue is. We won’t keep you waiting for long as our service department has their technicians on call to be able to fix the problem right away.

For you to feel secure with your decision of purchasing your windows from us, we encourage you to ask questions about the components of our warranty as well as the quality of our service. We will be more than glad to answer all your queries to help you make the right choice. We won’t keep you in the dark.

Precision Installation

All the door and window replacements that we offer come with precision installation by our in-house highly trained installers.

Even if you have the best windows in the market, designed and built with utmost consideration, they will not live up to their potential if not installed properly. In short, they can only be as good as their installation. This is the reason why Zen Windows does not outsource its installation crew to guarantee the proper performance of the window that you choose. Instead, we have our own team of dedicated professionals who have been trained to take full responsibility for the installation process. As part of our company, they adhere to the same level of excellence that we do.

No-Money-Down Guarantee

Our no-money-down policy will give you the assurance that you will not be saddled with sub-standard products or suffer the consequences of a bad install. As part of our efforts to give our clients the best Zen Windows experience, we won’t accept any payment until the project is finished and you are completely satisfied.

It is part of our commitment to aim for customer satisfaction at all times. At Zen Windows, we will not ask for any upfront payment. Unless the project is complete to your satisfaction, we won’t get paid. This is how we ensure that you get exactly what you paid for and more.
