Why Supplier + Installer Matters
Why Supplier + Installer Matters
Most homeowners don't realize that big-box stores and national window brands use subcontracted installers — meaning the company that sold you the window isn't the company putting it in. If something goes wrong, you're caught between two warranties and two phone numbers.
The contractor we connect you with is different. They supply and install every window themselves — direct dealer pricing on Milgard, Anlin, Marvin, and Simonton, installed by their own licensed crew. One company. One warranty. One call if anything ever needs attention.
This is also why our pricing calculator reflects real numbers. The contractor sets their own supply and installation pricing — no showroom markup, no franchise fee, no separate labor quote from a subcontractor.
Window Brands Your Contractor Installs
The Brands Bay Area Homeowners Trust
The contractor we connect you with is a direct dealer for the four brands most requested by Bay Area homeowners. They stock, supply, and install all four — dealer pricing and expert installation from the same company. Here's what you need to know about each brand.
Milgard
Milgard is the most widely installed window brand in California. Known for their lifetime warranty, energy efficiency, and wide product range — from the affordable Tuscany Series to the premium Trinsic.
Anlin
Anlin windows are manufactured in California specifically for the California climate. Their Del Mar and Catalina series offer exceptional energy performance and a True Lifetime Warranty that transfers to new owners.
Marvin
Marvin is the choice for homeowners who want premium wood-clad or fiberglass windows with exceptional aesthetics. Ideal for craftsman, Victorian, and high-end contemporary Bay Area homes.
Simonton
Simonton offers excellent value for budget-conscious Bay Area homeowners. Their StormBreaker Plus and Reflections series deliver solid energy performance and durability at a more accessible price point.
We connect you with a local, independent window contractor — one company that supplies and installs, start to finish. Not a national chain. Not a call center. Not a lead farm that sells your information to twelve contractors. You hear from one company. That's the entire model.

Performance
Union City Climate and Window Performance
Union City sits between Fremont and Hayward on the East Bay flatlands — a transitional microclimate influenced by both the bay and inland heat. Flatland areas near the bay experience moderate temperatures and some marine moisture, while neighborhoods further inland see warmer summers approaching the conditions of Fremont and Hayward.
Union City's 1960s–80s housing stock has a high concentration of original aluminum single-pane windows and early dual-pane units with failed seals — both of which are significant sources of heat loss in winter and heat gain in summer. Low-e double-pane glass with a balanced combination of SHGC and U-factor performance addresses both seasonal concerns.
All windows supplied and installed are Title 24 compliant and ENERGY STAR certified for the Western climate zone.
Best time to schedule: February–April. Most projects complete in a single day.
