AfterWindow Company in Redwood City, CA
Window and door work in Redwood City runs into conditions you won’t find in most Bay Area cities: salt-tinged air off the bay, an older housing stock that predates modern glazing standards, and microclimates that shift between the flats and the western hills. We’re Meridian Windows & Doors, a locally operated shop that replaces, installs, and services windows and patio doors across Redwood City with written pricing and a one-year guarantee on every job. Call (817) 686-2228 and you’ll reach a live person who can schedule a free estimate.
Why Redwood City Homes Are Different
Redwood City’s housing stock spans three distinct eras, and each one affects window and door work differently. The pre-1950 bungalows around Rose Park and Central Redwood City often have non-standard rough openings: a 28-inch-wide window frame from 1938 isn’t on any modern sizing chart, so replacement means custom-measuring and often minor framing adjustments. The 1960s and 1970s ranch homes in Woodside Plaza and the Farm Hill area came with single-pane aluminum frames that now sweat, corrode, and leak conditioned air. Newer construction in Redwood Shores, between the lagoons and Highway 101, deals with a different problem: wind exposure and constant marine air, which accelerates wear on hardware and weatherstripping.
The terrain matters too. Homes on the western edge of Redwood City, toward Emerald Hills and the 280 corridor, sit on sloped lots where drainage dictates how a patio door threshold must be flashed. A flat threshold on a grade can channel water back into the house. We spec those installs with tapered sills and end dams where needed. On the flats, older homes with settled foundations sometimes have frames that are out of square by a half-inch or more; a properly installed window in Redwood City means shimming to plumb and level rather than forcing the frame to fit the opening.
Our Main Redwood City Services
Most Redwood City homeowners call us for one of two reasons: replacing worn-out windows, or installing new windows and patio doors during a remodel or addition. All three services below have their own dedicated Redwood City pages with pricing detail, process notes, and local-specific guidance.
Window Replacement in Redwood City
Replacement in Redwood City frequently means pulling aluminum sliders from the 1960s or failed double-hungs from the 1980s and retrofitting modern units into openings that are no longer square. Many older Redwood City homes were built before low-E glass became standard, so we still see single-pane sashes with aluminum spacers sweating through Redwood City’s cool summer mornings. The work involves removing the old sash and frame, correcting any rot at the sill, and setting the new unit plumb with proper flashing. We write the price before work starts, and the installation is covered for a full year. Window Replacement in Redwood City
Window Installation in Redwood City
New construction and addition work in Redwood City follows a different path than replacement. The rough openings are often clear, so installers set the frame, square it with shims, and flash it before the exterior finish goes on. Redwood City’s hillside lots come into play here: homes on grades above Alameda de las Pulgas often need steeper flashing details at the sill. We work with the builder or directly with the homeowner, and we coordinate with the framing schedule so windows go in before stucco or siding closes the rough opening.

Patio Door Installation in Redwood City
Patio doors in Redwood City take the most weather abuse of any opening in the house. Sliding glass doors on Redwood Shores homes collect salt film and grit from the bay air, which eats rollers and tracks faster than inland. French doors and lift-and-slide units on older ranch homes face a different issue: the wall framing under the header has often settled, so the new door must be set to a level threshold rather than following the existing plane of the wall. We carry doors from Therma-Tru and ViewLux, and we’ll spec the right unit for your exposure and traffic pattern. Patio Door Installation in Redwood City

Two things push prices up in Redwood City: hillside access (scaffolding or restricted staging around homes near Emerald Hills), and non-standard rough openings in pre-1950 bungalows that need custom-sizing or framing adjustment. Whatever the job runs, the number goes on paper before any work starts, and it doesn’t move at the door.
