Completed replacement of fogged thermal-pane windows throughout a client's home. Seal failure caused condensation between panes. Carefully removed glass while preserving original wood frames. Installed new dual-pane units with warm-edge spacer technology and argon gas fill. Applied proper glazing techniques including appropriate setting blocks, compression gaskets, and minimal silicone sealant. Windows now provide clear visibility, improved energy efficiency, and UV protection while maintaining the home's architectural character and charm.
