Pinnacle’s superior Denver window and door installation process.

Improper window and door installation can cause leaking, malfunctioning windows, security concerns, property damage, and loss of the window manufacturer’s warranty (often a valuable lifetime warranty). Don’t leave one of the most important steps to an inexperienced company using inferior installation methods.

You may hear other window companies tout the benefits of a retrofit installation. Cheaper and faster is not always better. A retrofit is often the wrong installation method per code, voids a manufacturer’s warranty, and may result in damage to your home! Protect your windows and your home by choosing a full frame replacement.

The proper installation of a new door is equally important. Like windows, a retrofit application may void a manufacturer warranty, create security issues, and not protect your home from the elements. Make sure your replacement door is beautiful, easily functional, and secure by having it properly installed by an experienced installer!


What to expect: the Pinnacle Windows & Restoration Difference.

At Pinnacle we are proud of our ability to provide our customers with superior service and results! One thing we insist on is doing things THE RIGHT WAY. As our sales and installation team may have explained, there are two ways to replace windows.

Nail Fin


For several reasons, we strongly believe that a nailing fin installation is the only proper way to install replacement windows to maintain a whole house weather barrier:

  • The building codes specify that a nail fin installation is the proper method for the replacement window installations. AAMA code §2400-10. See also International Residential Code, §R609.1 as adopted by Douglas, Denver, Arapahoe, El Paso (Pikes Peak Regional), and Jefferson counties.
  • Maintain the look and size of your existing windows. Retrofit creates more layers of window frame and reduces the size of the glass opening on your windows (often by 20%).
  • Properly safeguard your home from water and weather. A nail fin installation creates a new, effective water and weather barrier similar to new construction. Retrofit requires the breaking of existing barriers, simply patches holes, and may include leaving damaged components in place.
  • Preserve the warranty included with your new windows. The value of a lifetime warranty cannot be understated. Many manufacturer warranties are voided by non-code compliant installation.

Inexperienced contractors or insurance adjusters may try to convince you that a retrofit installation is better because it MAY be cheaper or faster. Insist that your windows are installed THE RIGHT WAY with Pinnacle!

“Couldn’t have had a better experience! Customer service was best of the best. From scheduling through install communication was easy and timely. Product is beautiful. Highly recommended.”

Erica H.

“Overall it was a great experience working with Pinnacle Windows & Restoration! We had some broken windows due to a storm and Pinnacle sent a sales rep out that week to check out the damage. He was very knowledgeable and answered all of our questions. They whole process was super easy on our part, Pinnacle talked with our insurance agent and increased the amount they would cover. When our windows were installed we were very happy with how they looked and are definitely using Pinnacle again to get the rest of our windows replaced!”
