Ready to Start Your Project?

Renewal by Andersen is Here for You

Yes, we are open.
We remain open in Colorado and committed to helping homeowners when we can do so safely. Like you, we’re closely monitoring the health concerns facing our communities, and following CDC recommendations and best practices regarding Covid-19. The health and safety of our team members and customers is our highest priority. 

What safety measures have we taken? 

When you choose Renewal, you’ll work with a single project consultant to manage your job. On installation day, most of our master installers work in crews of two. Any teammate you invite into your home will follow CDC guidelines to limit the spread of the virus. We’ll even check with you before our visit to make sure your family members are feeling well. 

We’ve increased the frequency of cleaning at our facilities. Every one of our vehicles carry waterless soap, hand sanitizer, and disinfectant surface wipes for frequent cleaning of hands, tools, and material surfaces. Our project consultants, technicians and installers are washing hands frequently. During the few visits we do make, you’ll see us wearing protective gloves. 

We’ve implemented social-distancing protocols, so please bear with us when we don’t shake your hand. We’re just trying to maintain a respectful distance. Our installers use Zip Walls to isolate the work area. Upon completion of any work, they will thoroughly disinfect the area before leaving your home.   

With Renewal, you’ll be working with a single company that will manage every aspect of your project, and much of your installation can be completed from the outside—often in just one day. 

How can we help? 

Right now, our homes feel like our safe havens. For your peace of mind, we now offer virtual appointments too so you can make your home safer and stronger from the comfort of your own home.
For many, spring is the time to make the home improvements you’ve been holding off on. If you’re comfortable with us and the precautions we’ve taken, we’d be happy to be of service. If now isn’t the right time, that’s fine too. Being respectful of you and your home during these challenging times is just one of our promises to you. 

As always, we thank you for choosing Renewal by Andersen and look forward to helping you with your home improvement projects, both now and in the future.
