Andersen Wood Window Repair in Stamford, CT

When we arrived at this home in Stamford, CT, we were immediately greeted by a familiar issue: severe bottom corner rot on a classic Andersen wood window sash. The damage was extensive — moisture had completely compromised the lower joint and surrounding frame. It’s something we see often with Andersen windows that have been exposed to water infiltration over time, especially when the original factory finish begins to wear down.

At Prestige Window and Door Repair, Andersen repairs are a specialty we’ve mastered. Our first step was to remove the window sash from the frame without damaging the insulated glass unit or the compression seals. We carefully disassembled the rotted corner and assessed how much material could be saved. Due to the level of deterioration, we milled and installed a new corner block from kiln-dried pine, shaped to match Andersen’s factory profile down to the bevel and contour.

What makes Andersen wood window repair in Stamford, CT unique is the precision required to replicate their original joinery. We cut new joints, restored the bottom rail profile, and installed a new drainage kerf to help prevent future water collection. After aligning everything and bonding the wood with waterproof adhesive, we reinforced the joint with stainless fasteners to ensure long-term durability. The rebuilt sash corner now seats perfectly against the frame, just like it did when it was new.

Once the repair was complete, we prepped and primed the new wood using an exterior-grade bonding primer. This was followed by two coats of finish-grade paint to match the existing window color. One thing we never skip is sealing all seams and fastener points to block moisture reentry—a common oversight that leads to repeat repairs down the line. The window was then reinstalled and tested for fit, lock function, and sash movement.
