Casement Windows

We serve Northern California across three regions: the San Francisco Bay Area (six counties from Alameda to Santa Clara), Greater Sacramento (Sacramento out to Roseville, Folsom, and Davis), and the Central Valley (Stockton to Modesto). Our crews are based in Castro Valley. We handle permits and know the building codes for each jurisdiction, which matters because requirements and fees vary significantly between cities.

We offer $0-down financing with approved credit, 12-month same-as-cash plans, and extended terms up to 15 years for larger projects. You only pay for completed, inspected work — we never ask for full payment before the job is done. Your project manager will walk you through every option during your estimate appointment. We also accept checks, ACH, and all major credit cards.

Yes. CSLB License #1078806 — verify it anytime at cslb.ca.gov. We carry $2M general liability, full workers’ comp, and are bonded per California law. We hold GAF Master Elite, Owens Corning Preferred, CertainTeed ShingleMaster, and James Hardie Elite Preferred certifications — each requires annual training and quality audits to maintain. We’re happy to provide proof of insurance before any work begins.

Most exterior projects in Northern California require a building permit. Fees vary by city — Oakland runs $200–$600, Peninsula cities often more. We handle the entire permit process: application, plan submission, and scheduling inspections. Permit fees appear as a separate line item in your estimate so you’ll see every cost upfront. For homes in WUI fire zones (Berkeley Hills, Oakland Hills, parts of Marin), we ensure full compliance with local fire-rated material requirements.

Casement windows seal tighter (better energy performance) and capture significantly more airflow when open. Double hung windows are better for traditional-style homes and locations where an outward-opening sash would obstruct a walkway or patio.

Yes. Casement windows provide the largest clear opening per unit size, making them ideal for meeting California bedroom egress requirements (5.7 sq ft clear opening, 24" minimum height, 20" minimum width). We size all bedroom casements to code.

Each casement window takes 50–70 minutes to install due to the precision alignment the crank mechanism requires. A full-home replacement of 10–15 casements is completed in 2–3 days, including removal, rough opening prep, flashing, foam insulation, and all interior/exterior trim.

Casement windows are the most energy-efficient operable window type. Our Andersen and Marvin casements with dual-pane Low-E glass achieve U-factors of 0.22 and SHGC below 0.25, exceeding Title 24 prescriptive requirements by 15–25% for all Bay Area climate zones (CZ 3, 4, and 12).

The crank mechanism needs light lubrication with silicone spray once a year — about 30 seconds per window. The hinges and multi-point locks are maintenance-free for 15–20 years. In salt-air zones within a mile of the coast, we recommend annual inspection of hardware for corrosion. Overall maintenance is comparable to double hung and less than sliding windows, which accumulate debris in the track.
