Window Styles 
Choose the Window Style That Fits the Opening
Single-Hung Windows
A fixed upper sash and operable lower sash for familiar operation, ventilation, and a straightforward replacement path.
Single-Slider Windows
Horizontal operation where exterior swing clearance is limited, with the opening and drainage details measured before ordering.
Sliding Glass Doors
Large glazed openings coordinated with sill support, flashing, drainage, operation, safety glass, trim, and adjacent finishes.
Picture Windows
Fixed glass for daylight and views, planned around glass size, exposure, energy ratings, structural support, and interior trim.
Double-Hung Windows
Two operable sashes for flexible ventilation, with frame proportions and trim selected for the home and opening.
Casement Windows
Hinged windows with compression seals, planned around swing clearance, hardware access, ventilation, and egress needs.
Daly City's housing stock spans 5% pre-1940, 40% 1940-1960, 30% 1960-1985. Architectural styles range from 1940s-50s Westlake-style Doelger tract homes with uniform stucco facades to postwar Victory homes. Each era and style presents different windows requirements — from material compatibility to structural considerations. Our crews know what to expect before they arrive on site.
Neighborhoods We Serve
Windows Across Daly City Neighborhoods
Local planning starts with the site, neighborhood context, access, and applicable city review.
Colma
Colma homeowners frequently choose Hamilton Exteriors for windows. Extreme wind and fog require high-performance weatherstripping. With Daly City's Coldest and foggiest Peninsula city: summer highs 58-68°F, winter lows 42-48°F, material selection in Colma requires local expertise.
Hillside
In Hillside, homes are predominantly postwar Victory homes. Vinyl outperforms aluminum in this corrosive environment. Our crews are familiar with Hillside's architectural character and building requirements.
Westlake
Westlake's Doelger homes often retain original single-pane windows that allow fog moisture and cold drafts. Modern dual-pane replacements dramatically improve comfort and reduce condensation in these classic Daly City homes.
Broadmoor
Broadmoor homeowners upgrade windows to combat Daly City's persistent fog-driven drafts. We install energy-efficient dual-pane windows with proper weatherstripping that transform indoor comfort year-round.
Serramonte
Serramonte homes gain significant energy savings from window replacement. Original 1960s-70s aluminum frames allow substantial heat loss. Modern vinyl or fiberglass frames with Low-E glass cut heating costs measurably.

I scheduled to have someone come give me an estimate for all new windows in our 1950s home with not so great Remodeling work by previous owners. Alex Li promptly met with us & his crew throughout the entire process. They were always on time to work, left our home clean of debris & spectacular new JeldWin windows. Helped me with getting Financing as well...Just all around a great experience & highly recommend!

I recently hired Hamilton Exteriors to replace my siding and windows, and they did a fantastic job. Their team was punctual, polite, and paid close attention to detail. The siding looks seamless, and the new windows have made a noticeable difference in both appearance and energy efficiency. Communication was always clear, and they finished on time and within budget. I’m very happy with their work and would definitely recommend them.
