When to Call a Window and Door Replacement Company in Denver 

Windows and doors today last longer and save you money on energy costs. While you may have considered replacing your old ones, you may not know whether you need to do it now, or you can get a few more years out of them.  

Have you noticed leaks or condensation around your windows? Do you have cracks in the glass or gaps in the sealant around your doors or windows? Have your energy bills gone up recently even though you haven’t changed anything in your home?  

If you answered yes to any of these questions or you’ve had other issues with your doors and windows, you need a window and door replacement. Colorado Window Source and More is your reliable window and door replacement company in Denver, and we’ll do the job right the first time. 


Replacement Windows in Denver

When a baseball comes crashing through your window, you don’t always have time to plan a replacement. However, not all damage happens so suddenly. If you notice moisture, mold, or high energy bills, your windows may be the culprit.  

Whether you are going for a modern look or a more rustic look, there is a window to fit your preference and home design. Colorado Window Source and More has experience installing: 


  • Anlin windows 
  • Sunrise windows 
  • JELD-WEN wood windows 
  • Milgard windows 
  • Egress windows 

No matter which style or material you choose, replacing your windows can lower heating and cooling costs, reduce window maintenance, promote easier cleaning, increase your home’s value, and keep your family safe. You can save time and money by replacing the windows throughout your home as soon as you recognize a problem.   

Replacement Doors in Denver

By switching out your old doors, you save energy. Older doors tend to let out cold air in the summer or heat in the winter. When the warm or cold air escapes, your energy system works that much harder to keep your home’s interior comfortable, leading to higher energy costs.  

Replacing your old doors creates a domino effect. You save energy by switching out the old or faulty door, which means you pay less to keep your home at the right temperature. Even if you pay the price for high-quality doors, you’ll save in the long run.  

We have Therma-Tru entry doors, Therma-Tru patio doors, and Sunrise patio doors. The Therma-Tru Smooth Star Sliding Patio Door System uses durable fiberglass and fine painted wood, so it won’t rust or dent like steel doors.
