Window Replacement Services in Belmont, San Mateo County

Deluxe Windows has been serving Belmont homeowners with expert window and door replacement for over 30 years. From energy-efficient vinyl windows that meet California's Title 24 standards to premium systems from brands like Milgard, Andersen, and Anlin — we carry every material and style needed to upgrade any Belmont home. Belmont's hillside Water Dog Lake neighborhoods and the flatter corridor near Ralston Avenue feature a classic Peninsula mix of 1950s ranch homes and 1960s split-levels where aluminum single-pane windows are still common — delivering poor thermal performance and persistent condensation on cold mornings. Our certified installers handle all Belmont city permits and inspections so you don't have to.

Belmont's microclimate brings persistent morning fog rolling in from the Bay and mild afternoons, creating ideal conditions for condensation buildup on older aluminum frames. Homes range from flat-lot ranches near Ralston to steeply pitched hillside properties with dramatic bay views — each requiring different window proportions and performance specs. Milgard's Tuscany vinyl series is a top seller in Belmont for its warm sightlines and excellent thermal ratings. Our certified installers measure, order, and install every window with precision. Most Belmont projects are completed in just 1–2 days.

Do You Have Any Question?

Call us at (888) 730-4144 to ask your questions.

How much does window replacement cost in Belmont?

Belmont homeowners typically invest $6,500 to $14,000 for a full window replacement project covering 10–15 windows. Belmont Hills properties with larger windows and custom configurations will see costs at the higher end of that range. Single window installations start around $550–$650.

Do I need a permit to replace windows in Belmont?

Yes. Belmont requires a building permit for window replacement projects, particularly those involving changes to rough opening size or framing. Like-for-like replacements may qualify for a streamlined permit process. Our team handles all Belmont permit applications on your behalf.

Is it worth replacing 20-year-old windows in Belmont?

Often yes. Twenty-year-old windows in Belmont commonly show fogged glass, drafts and weak locks. Newer ENERGY STAR units improve comfort and curb appeal; Deluxe Windows compares payback against your utility rates and home style before recommending replacement.

Should I choose fiberglass or vinyl windows in Belmont?

Vinyl is the value pick for most Belmont replacements and handles Bay Area weather well. Fiberglass (including Marvin Ultrex) is stronger, more stable in temperature swings and better for larger openings or coastal exposure. We show both side by side in the showroom and on-site.

How long does window replacement take in Belmont?

Most Belmont projects are measured in one visit and installed in one to three working days once products arrive — typically four to eight weeks after ordering, depending on brand and custom sizes.

* Price applies to minimum window installation size of 24"x24".
