Absolutely not. Our advice is to never give a down payment to a window company. We would never ask for payment on services not rendered.

Pay with cash, check, or the credit card you choose. We also offer financing on window replacement and installation.

Yes. We offer 12 months same-as-cash or an option that’s tailored for your situation. Call (303) 658-9990 or contact us online for details.

After you’ve received your window installation quote and have decided that you’d like Zen Windows of Denver to replace your windows, just give us the go-ahead. Usually, we’ll come in a few days to take exact measurements. After that, we’ll complete your project in three to five weeks.

We proudly offer Soft-Lite Windows, which are manufactured in Streetsboro, Ohio. After thousands of Soft-Lite window installations in the Denver, area, we’ve never had an issue with the altitude.

Yes, and we believe our warranty is pretty special. Not all lifetime warranties are created equal. Our warranty covers every window we sell, and as long as your home is still standing, you’ll never have to spend another dime on your windows. This means we pay for the window, glass, installation, and trip expenses. There’s no fine print or exclusions, and the warranty is fully transferable every time the home sells. How much more zen could a warranty be?

When a windowpane is broken, replacing just the glass may seem like a less costly alternative to replacing the entire window, but there are several factors to consider. The replacement glass will likely have a shorter, less inclusive warranty than the rest of the window. Plus, if anything other than the impact contributed to the glass failure — such as a warped frame, a faulty counterweight, or damaged seals — that same issue may cause the new glass to fail. Finally, the replacement glass won’t be nearly as energy-efficient as the original window or a new one, counteracting much of the savings of a glass replacement.

Yes, we do! To prevent heat loss, we take all precautions possible. We replace a minimum number of windows at a time and close off rooms as we work.

If you want a stranger to come to your home and give you the old “dog-and-pony show” sales pitch with heat lamps on your kitchen table, we probably aren’t the company for you. Our goal is to make replacing your windows fast, easy, and hassle-free.

No. A quote from Zen Windows is more than an estimate — it’s a promise. We won’t change the quote when we come to measure (or ever!).

After years of quoting projects, we’ve learned to ask the right questions to get the needed information. Zen Windows of Denver also uses internet research. If you have something unusual, just email or text us a picture. It’s that simple.
