Many homes in Passaic and the surrounding towns still have windows that are thirty or more years old. Some still work fine. Others are quietly costing money on heating bills every winter.
First, drafts. If you can feel air moving near a closed window on a windy day, heat is leaving the house. Weatherstripping helps for a while, but worn frames eventually need replacing.
Second, fogging between the panes. That means the seal on a double-pane unit has failed and the insulating gas has escaped. The glass can't be cleaned, and the window has lost most of its insulating value.
Third, sashes that won't stay up, won't lock, or take two hands to open. Fourth, soft or rotted wood at the sill, which often means water has been getting in for some time. Fifth, condensation or frost building up on the inside of the glass in winter.
When we replace windows, we open up each frame, repair any rot, flash and insulate around the new unit, and finish the trim inside and out. One opening at a time, so your home is never left open to the weather.
