Window Replacement in St. Louis
Old windows are one of the biggest sources of energy loss in a home. Redwood Exteriors replaces windows throughout Greater St. Louis with energy-efficient units that reduce drafts, lower utility bills, and improve the look and comfort of your home.
Signs It Is Time to Replace Your Windows
Drafts and air infiltration
If you can feel air movement around a closed window, the seals have failed. New windows eliminate drafts and make your home more comfortable year-round.
Fogged or cloudy glass
Fogging between panes means the insulating gas has escaped and the thermal seal has failed. The window is no longer performing as designed and should be replaced.
Difficulty opening or closing
Windows that stick, won't lock, or are painted shut are a safety hazard and a sign of frame deterioration. Replacement restores proper operation and security.
High energy bills
Single-pane windows and failed double-pane units transfer heat and cold directly into your home. Modern energy-efficient windows significantly reduce heating and cooling costs.
Visible damage or rot
Wood frames that are rotting or vinyl frames that are cracked or warped allow moisture into your wall assembly. Replacement stops the damage before it spreads.
Our Window Replacement Process
We start with a free in-home measurement and estimate. Every window opening is measured precisely — replacement windows are not one-size-fits-all, and a proper fit is critical to performance and appearance.
Once you approve the estimate, we order your windows and schedule the installation. Most window replacement projects are completed in one to two days depending on the number of windows.
On installation day, we remove the old windows carefully, inspect the rough opening for moisture damage, and install the new units with proper flashing and sealing. We clean up completely before we leave and haul away all old materials.
