Window Installation & Replacement

Old or failing windows are one of the largest sources of energy loss in foothill and coastal homes. Single-pane glass and deteriorated seals let conditioned air escape, force HVAC systems to work harder, and create uncomfortable drafts near seating areas and bedrooms. Replacing those windows is one of the most cost-effective upgrades a homeowner can make, both for monthly utility savings and long-term property value.

Colfax Glass installs replacement windows from Milgard, Ply Gem, Coeur D'Alene, and JELD-WEN. We carry vinyl, fiberglass, and wood-clad frame options and pair them with Low-E glass coatings sized to your home's orientation and climate zone. For Auburn and Roseville properties that take direct afternoon sun, we often recommend dual-pane units with a U-factor below 0.30 and a solar heat gain coefficient tuned for hot summers. For Brookings and Crescent City homes facing salt air and coastal wind, we focus on corrosion-resistant frames and impact-rated glazing.

We handle both retrofit installations, where the new window fits inside the existing frame, and full-frame replacements, where we remove everything down to the rough opening. Retrofit is faster and less invasive; full-frame is better when the existing frame is damaged or when you want to change the window size. During our in-home assessment, we inspect the framing, check for moisture damage, and recommend the right approach for each opening.

Every installation includes weatherstripping, insulation around the frame cavity, and clean interior and exterior trim work. We haul away old windows and leave the job site clean. Homes across Colfax, Grass Valley, Nevada City, Loomis, Rocklin, and Sacramento have all benefited from this straightforward process.
