NATIONAL STRENGTH.  LOCAL SERVICE.

12 Penny Exteriors is an independent and locally owned company proudly partnered with the third largest home improvement chain in the country, Window Depot USA.  As a member of a large national network, we are able to harness the bulk buying power of a much larger company, which means passing on cost savings on quality products to you, our customer.  

As a local business based in Littleton, we have a strong dedication to the quality of service we provide to the homeowners we consider our ‘neighbors.’ We are committed to providing an easy and comfortable home improvement experience, from offering expert advice at the beginning of a project all the way to leaving your home as clean as we found it after we’re finished. 

When it comes to increasing energy efficiency and improving curb appeal, comfort, and noise levels in your home, upgrading your home’s exterior components is a smart investment.  12 Penny Exteriors offers many different types of replacement windows, entry doors, sliding glass doors and insulated siding.  We provide expert and experienced guidance as to the best product for your particular project and budget.  You can trust that our installation team will get the job done right: in fact, we guarantee it.
