A PEEK INTO THE RENEWAL BY ANDERSEN® START-TO-FINISH PROCESS

The Renewal by Andersen® of St. Louis window replacement process is designed to minimize the inconveniences traditionally associated with home improvement. It’s one of the building blocks of our Signature Service, separating us from our competitors.

Peek Renewal Andersen Start Finish Process

In a nutshell, here’s what we do to carry out hassle-free windows installation one project at a time:

Construction-Proofing the Site

We begin the process by protecting the job areas from mess. We don’t start the window replacement until we lay down drop cloths, mats and runners to cover every inch of the site. Preventing property damage is a primary concern of ours, which is why we make the effort to cover valuables against dust, debris and foot traffic. We even wear protective footwear to avoid bringing dirt and mud inside.

Removing Windows With Weather in Mind

We understand and recognize the challenges of installing double-hung, picture, bay, bow, sliding, specialty and casement windows during inclement weather. This is why we’ll minimize outdoor exposure to your home, especially when it rains. If we need to, we’ll create a shelter outside to shield the installation site from the elements.

Sealing Newly Installed Windows

We remove and install windows with meticulous attention to detail. Our products are already custom-built to fit within a 16th of an inch into the existing opening, but we fill the tiny gaps around with insulation foam. This way, we can guarantee an airtight seal for maximum weather resistance and energy efficiency.

Demonstrating Every Unit

After installation, we’ll show you how our energy-efficient windows operate so you can use them properly and safely. If you have final questions, we’ll answer them to your satisfaction to help you become a responsible window owner.

Leaving the Site as Clean as (or Cleaner Than) When We Arrived

Before calling it a day, we’ll leave your home exactly like when we arrived – or cleaner with better windows. Our final cleanup doesn’t take forever because we clean as we go. We have trash bins on site to immediately dispose of garbage, keeping hazardous debris from falling to the ground.

Reviews

"Have nothing but great things to say about the window installation done today by John Hutchinson with Renewal by Andersen! He was friendly, personable and professional and did a great job installing. He did a great job of putting down roller pads and tarps with next to zero clean up. Would highly recommend them for any window replacement needed!"

"We had our new Renewal by Andersen windows installed on June 5th & 6th, 2025 and we LOVE them! The quality, beauty, and functionality are best-in-class! The whole experience from dinner presentation at Lazy River Grill, the initial in-home sales consultation and measurement, the regular communications from the salesman and concierge, and the installation team’s professionalism and skills made the process so seamless. This is the second home we have opted for Renewal windows and doors and have been delighted both times! Thank you Renewal by Andersen STL! "

"I had an excellent experience with RbA STL. Our designer, Courtney, was great and the finished product is awesome. The installation was easy and the gentlemen left our home cleaner than they found it upon entering. I would recommend RbA STL - you’ll get tired from their constant contacts, and that’s a GOOD thing!"
