Replacement and Retrofit Windows To Fit Any Project

Full Frame Replacement Windows

Full-frame window replacements replace the exterior and interior trim and windowsills that may have become over years of abuse and overall aging from the windows themselves. With full-frame replacement windows in St. Louis, the entire window and trim is removed, leaving only the rough opening where the new window, casement and trim are then installed. A full-frame installation is usually recommended when there is significant rot or deterioration to the exterior wood components of a window opening. This remediates the problem of the rotten wood and prevents additional damage to your home.

Retrofit Windows

In many older or historic homes, a full frame window replacement is not the best option, or even an option at all. In these cases, retrofit windows are installed with a focus on three layers of ‘insulation’ to produce cost savings (nearly) identical to full replacement. With window retrofits, exterior storm windows, interior storm windows, and interior thermal blinds, are combined to optimize heating and cooling costs but still maintain the look and integrity of the original window style.
