How long does it take to replace windows in a house?

Most whole-home projects (10-20 windows) take 2-4 days of on-site work. The larger variable is lead time on materials, which typically runs 3-6 weeks depending on the manufacturer and product line.

How much does it cost to replace windows?

Installed cost per window generally falls between $400 and $1,200, depending on size, frame material, glass options, and whether it is a retrofit or full-frame install. We provide itemized quotes after the in-home assessment.

What is the difference between retrofit and full-frame window replacement?

Retrofit is a good fit when the existing frame is structurally sound and you want to minimize cost and disruption. Full-frame replacement is the better choice if there is rot, water damage, or if you want to resize the opening. We assess this during the initial visit.

Do replacement windows save energy?

Yes. Upgrading from single-pane to dual-pane Low-E windows typically reduces heating and cooling costs by 15-25%. The improvement is especially noticeable in foothill homes that deal with 100-degree summers and cold winter mornings.

Do you serve Dutch Flat and Gold Run from your Colfax shop?

Yes. Dutch Flat, Gold Run, and Alta are all within a short drive of our headquarters. We regularly complete projects in these communities and can usually schedule them the same week.

How quickly can I get a quote for a Colfax project?

For Colfax residents, we can often do a site visit and provide a written quote within one to two business days. Urgent requests like broken glass may be handled the same day.

My Colfax home was built in the 1940s. Can you work with non-standard window sizes?

Absolutely. Many older Colfax homes have window openings that do not match modern standard sizes. We measure on site and order custom-sized units, or we can modify the opening for a retrofit installation.

Window Installation & Replacement — What to Expect

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.

Window Installation & Replacement for Colfax, CA Homes

Colfax sits at roughly 2,400 feet along the I-80 corridor, where the Sacramento Valley transitions into the Sierra foothills. The town's housing stock reflects its railroad heritage: older wood-frame homes from the early 1900s sit alongside newer construction from the 1990s and 2000s. Many of these older homes still have original single-pane windows that leak air and struggle against foothill temperature swings. Our shop at 226 N Auburn St means Colfax residents get the fastest turnaround of any area we serve.

Winter temperatures in Colfax regularly dip below freezing, and summer highs push into the upper 90s. That range puts serious demand on windows and doors. We recommend dual-pane, Low-E glass for most Colfax homes to reduce heat gain in summer and retain warmth in winter. For homes on the north side of the canyon or in shaded lots, condensation resistance is an important factor in product selection.

Because we are headquartered here, we know the local building styles inside out. We handle everything from single-window replacements in downtown bungalows to full-house upgrades in the newer subdivisions off Grass Valley Street. We also serve nearby communities including Alta, Gold Run, and Dutch Flat from this home base.
