Old windows cost you money every month. They let conditioned air escape, allow outside heat to pour in, and force your HVAC system to work harder than it should. In Las Vegas, where air conditioning accounts for a large portion of your energy bill, replacing worn-out windows is one of the best home investments you can make.
Signs You Need New Windows
Not every window needs to be replaced, but certain signs indicate it is time. Watch for these:
- Drafts around closed windows. If you can feel air movement near a closed and locked window, the seals have failed or the frame has warped.
- Condensation between panes. Fog or moisture between the glass layers of a double-pane window means the seal is broken and the insulating gas has escaped. The window is no longer performing as designed.
- Difficulty opening or closing. Windows that stick, jam, or will not stay open have balance or frame issues that usually mean the window is past its useful life.
- Visible damage. Rotting wood frames, cracked glass, corroded hardware, and warped vinyl are all signs that replacement, not repair, is the right call.
- High energy bills. If your energy costs have been climbing despite a well-maintained HVAC system, your windows may be the weak link in your building envelope.
- Single-pane glass. If your home still has single-pane windows, upgrading to double-pane insulated glass with Low-E coating will make a noticeable difference in comfort and energy use.
Energy Savings
According to the U.S. Department of Energy, heat gain and loss through windows accounts for 25% to 30% of residential heating and cooling energy use. In a Las Vegas home, the majority of that is heat gain. Replacing old single-pane windows with modern double-pane, Low-E, argon-filled windows can reduce cooling costs by 15% to 25%, depending on the size of your home and the condition of your current windows.
Beyond energy savings, new windows reduce outside noise, block UV rays that fade furniture and flooring, and improve your home's curb appeal and resale value.
The Replacement Process
Here is what a typical window replacement project looks like from start to finish:
- Consultation and measurement: A specialist visits your home to assess your current windows, take precise measurements, and discuss options for frame material, glass type, and style.
- Product selection: Based on your needs and budget, you choose window products. For Las Vegas homes, we typically recommend vinyl or fiberglass frames with double-pane, Low-E, argon-filled glass.
- Manufacturing: Your windows are custom-built to your exact measurements. This usually takes two to four weeks.
- Installation: Our installers remove the old windows, inspect the rough openings for any damage, install the new windows, and seal everything with flashing and caulk. Most homes can be completed in one to two days.
- Final inspection: We walk through every window with you to confirm proper operation, clean up the work area, and answer any questions.
Las Vegas Weather Considerations
Our desert climate creates specific demands on windows. Intense UV exposure degrades seals and finishes faster than in milder climates. Summer temperatures push glass surface temperatures above 150 degrees on south- and west-facing walls. Dust storms and monsoon rains test weatherstripping and frame integrity.
Choosing windows rated for hot, arid climates, and having them installed by experienced professionals, ensures they perform well for decades. Look for ENERGY STAR certification for the Southern climate zone.
