Replacement windows in Alameda, CA

Custom Exteriors replaces windows in Alameda homes with Infinity by Marvin fiberglass windows, installed by our own full-time AAMA Certified Master Installers. We are not a subcontracting broker. The same crews that measure your openings are the crews that install them.

From Gold Coast Victorians to Bay Farm Island townhomes, we match each window to the house it goes into, and we handle the City of Alameda permit process as part of the project.

Why Alameda homes need a different approach to window replacement

Alameda's housing stock is older and more architecturally specific than most East Bay cities, so a standard retrofit window often looks wrong on these homes. The island has well over a thousand Victorian-era homes, and in the Gold Coast neighborhood roughly 70% of homes were built in 1939 or earlier.

Each part of the island asks for something different:

Gold Coast and Bronze Coast. Queen Anne, Stick, and Colonial Revival Victorians with tall double-hung sashes, angled bays, and divided lite patterns that define the facade.
East End and Fernside. Craftsman bungalows and postwar ranch homes, where proportion and trim depth matter more than ornament.
West End. Historic cottages and Victorians alongside newer infill near Alameda Point.
Bay Farm Island and Harbor Bay. Planned townhomes and tract homes from the 1970s onward, many still on their original builder-grade windows.

Our design consultants start with the architecture, then choose the window style, sightlines, and grille pattern that fit it. That approach also lines up with what the City expects to see in a permit submittal.

Infinity by Marvin fiberglass windows for Alameda homes

Infinity by Marvin windows are made from Ultrex pultruded fiberglass, which holds its shape and finish in the wind and moist bay air that Alameda homes deal with year-round. Fiberglass expands and contracts at nearly the same rate as glass, so seals stay tight through daily temperature swings instead of pulling away over time.

What that means on an island home:

No rot, no warping. Unlike original wood sashes, fiberglass frames do not absorb moisture.
A painted look without the repainting. Infinity's factory finish gives Victorian and Craftsman homes the crisp, flat painted look they need, without the maintenance cycle of wood.
Glass built for Title 24. Multiple Low-E glass packages meet California's energy code. See energy-efficient windows and patio doors for how the options compare.
Made to measure. Every window is built to your opening, not pulled from a standard size chart.

Custom Exteriors is an Infinity by Marvin Platinum Partner. Infinity by Marvin windows are the only replacement windows we install. If you're weighing materials, our fiberglass vs. vinyl windows comparison lays out the differences.

Window styles we install in Alameda

The right style depends on your home's era and how each room is used. These are the Infinity by Marvin styles we install most often on the island:

Double-hung and single-hung windows. The standard for Victorian and Craftsman facades, with divided lite patterns available to match the original sash.
Bay windows. For the angled bays common on Gold Coast Victorians.
Casement windows. Strong ventilation and a tight seal for bay-facing rooms.
Sliding windows. A clean fit for ranch homes in the East End and newer homes on Bay Farm Island.
Awning windows. Ideal over kitchen sinks and in bathrooms.
Picture windows. For views toward the bay, the estuary, or the San Francisco skyline.

Want to see them in person? Every style is on full-size display at our Pleasanton showroom.

Replacing windows on Alameda's historic homes

You can replace windows on a historic Alameda home with fiberglass, as long as the new windows match the original's visual character. The City of Alameda's Window Replacement Guidelines state that replacement windows do not have to be the same material as the originals. What the City looks at is style, size, placement, and grille pattern.

For homes where earlier owners swapped in mismatched windows, replacement is a chance to restore the original look. Our design consultants use the home's architectural style, neighboring homes of the same era, and any old photos you have to specify windows that bring the facade back.

Alameda window replacement permits and Design Review

Replacing windows in Alameda requires a City building permit. Whether you also need Planning Design Review depends on what changes:

Usually exempt from Design Review: replacing windows at the same size and location with an architecturally consistent window.
Requires Design Review: substantially changing a window's size or location, or installing a style that isn't a restoration of the original.
Grilles between the glass: exempt only when they replace original windows that also had internal grilles, which is common in Harbor Bay.

The City asks for photos of the existing windows, product information, a floor or site plan, and a window schedule. Custom Exteriors prepares this documentation and handles the permit process as part of your project, so you are not managing City paperwork yourself.

Homes built before 1978

If your Alameda home was built before 1978, its window frames and trim may have lead-based paint, and federal law requires lead-safe work practices when that paint is disturbed. That covers most of the island's Victorian, Craftsman, and postwar homes.

Custom Exteriors is EPA Lead-Safe Renovation, Repair, and Painting (RRP) Certified. We confirm whether lead-safe procedures apply before installation and follow them to protect your family and our crew. Learn more about window replacement for homes built before 1978.

Installed by our own crews, not subcontractors

Every Custom Exteriors window is installed by a full-time employee who is an AAMA Certified Master Installer. Installation quality decides how a window performs for the next 20 years, and that is the part many window companies hand off to whoever is available.

Our installers have the training to handle the out-of-square openings, old framing, and original trim that come with a 100-year-old house. Meet the Custom Exteriors installation team, or read why employee installers vs. subcontractors matters for your project.

Frequently asked questions

Do I need a permit to replace windows in Alameda? Yes. The City of Alameda requires a building permit for window replacement. Same-size, architecturally consistent replacements are generally exempt from Planning Design Review, while changes to a window's size, location, or style require it. Custom Exteriors prepares the submittal and handles the permit process for you.

Can I put fiberglass windows on my Victorian? Yes. The City's guidelines allow replacement windows in a different material than the originals, as long as the visual character matches. Infinity by Marvin fiberglass windows can be specified with the sash proportions and divided lite patterns that Victorian facades call for.

How much does window replacement cost in Alameda? Cost depends on the number of windows, their sizes and styles, the glass package, and how much trim and framing work your home needs. Older Alameda homes often need more custom work than newer construction. We provide a detailed, itemized estimate after an in-home consultation. Our window cost guide explains what moves the number.

Will new windows help with noise from Oakland Airport or nearby traffic? They can make a noticeable difference. Bay Farm Island sits next to Oakland International Airport, and well-sealed fiberglass windows with the right glass package reduce outside noise compared with aging single-pane or builder-grade windows. Results depend on your current windows and your home's construction. Read more about noise-reducing windows.

How do I know it's time to replace my windows? Common signs include drafts, condensation between glass panes, sashes that stick or won't stay open, soft or rotting wood, and rising energy bills. If your windows are single-pane or more than 25 years old, replacement usually makes more sense than repair. See our tips on foggy windows.

How long does window replacement take? Installation for most homes takes one to a few days, depending on the number of windows and the trim work involved. Because every Infinity by Marvin window is made to order, the full timeline also includes manufacturing lead time and permit approval. Your design consultant will give you a project-specific schedule.
