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.

Compliance
Window Replacement Permits in Berkeley
Window replacement in Berkeley requires a building permit from the City's Planning and Development Department. Applications can be submitted online or in person at the Permit Service Center.

The contractor we connect you with pulls all required permits and coordinates the required City inspection. You don't need to navigate this yourself.
Performance
Berkeley Climate and Window Performance
Berkeley's climate is shaped by its position on the bay and the Berkeley Hills. The flatlands and waterfront neighborhoods stay cool and foggy much of the year, while the Berkeley Hills — including Claremont, La Loma Park, and Panoramic Hill — can be 10–15 degrees warmer in summer with more direct sun exposure.
Historic brown-shingle and craftsman homes common in North Berkeley and Elmwood often still have original single-pane windows with minimal weatherstripping. These homes see significant comfort improvement and noise reduction from modern dual-pane low-e replacements, especially along busy corridors like Shattuck Avenue and Telegraph Avenue.
All windows supplied and installed are Title 24 compliant and ENERGY STAR certified for the Western climate zone. Qualifying installs may be eligible for PG&E rebates.
Best time to schedule: February–April. Contractors are more available before summer demand peaks and most projects complete in a single day.

Common Questions
Window Replacement FAQ — Berkeley
Answers from real Bay Area window contractors.
How much does window replacement cost in Berkeley?
Costs depend on material, window count, and install type. Berkeley's older craftsman and brown-shingle homes often require full-frame replacement rather than standard retrofit due to non-standard window sizing and deteriorated original frames. Use our pricing calculator for a real estimate in 60 seconds — no contact info required.
What window brands are most popular in Berkeley?
The contractor we connect you with installs Milgard, Anlin, Marvin, and Simonton. For Berkeley's craftsman and brown-shingle homes, Marvin's wood-clad and fiberglass options are popular for matching historic character. Milgard and Anlin vinyl and fiberglass are most common for standard retrofits throughout the flats.
How long does window installation take in Berkeley?
Most projects — four to ten windows — complete in a single day. Older homes with non-standard sizing or full-frame replacements may require additional time.
Do I need a permit to replace windows in Berkeley?
Yes — Berkeley requires a building permit for window replacement. Applications can be submitted online or in person at the Permit Service Center. Berkeley contractors must hold a valid Berkeley business license in addition to their California CSLB license. The contractor we connect you with handles all permit applications and coordinates the required inspection.
Are energy-efficient windows worth it in Berkeley?
Yes — especially for older craftsman and brown-shingle homes in North Berkeley and Elmwood that still have original single-pane windows. Berkeley's cool, fog-influenced climate makes heat retention the primary performance goal. Low-e double-pane glass with a low U-factor reduces heat loss substantially and improves comfort year-round. PG&E rebates may be available for qualifying installations.
