Get answers to common questions about windows services in Cupertino, California.
In Cupertino, a full home window replacement typically ranges from $15,000 to $40,000+, depending on the home's size and window count. Key cost factors include the choice of high-performance materials (like dual-pane, Low-E glass for our climate), the complexity of installation in older homes, and compliance with California's strict Title 24 energy codes. Premium windows that meet these codes may have a higher upfront cost but offer significant long-term energy savings.
Yes, a building permit is generally required for window replacements in Cupertino, as the work must comply with state and local building codes, including seismic safety and energy efficiency (Title 24). A reputable, licensed local contractor will typically pull this permit on your behalf as part of their service. Always verify that your installer is licensed (check the CSLB license number) and includes permit costs and handling in their written estimate.
Cupertino's warm, dry summers and mild winters make high solar heat gain coefficient (SHGC) ratings important for reducing cooling costs. Given nearby wildfire risks, some homeowners opt for tempered glass windows which are more resistant to heat and breakage. The best installation timing is during the dry season (late spring to early fall), but planning well ahead is crucial as reputable contractors book up quickly.
Prioritize companies with a strong local presence in the South Bay, valid CSLB licensing, and specific experience with Cupertino's diverse housing styles, from mid-century homes to newer developments. Look for certifications from major window manufacturers and insist on detailed, written quotes that include all labor, materials, permit fees, and a clear warranty covering both product and installation workmanship.
Common issues include improper sealing leading to air leaks (compromising energy efficiency) and condensation between panes, indicating a sealed unit failure. Due to local seismic activity, ensuring the window frame is properly integrated with the home's weather barrier and structure is critical. A trustworthy local installer will provide a robust warranty and promptly address any such issues, as proper installation is key to passing potential home inspections in the future.
