What makes apartment window replacement different?

Scale and occupancy. A forty-unit building is one job with forty tenant schedules attached, not forty separate jobs — so it needs one price, one crew plan, and coordination you do not have to run yourself.

That single difference changes how we price, how we schedule, and how we work around your tenants. A 40-unit building is not forty separate jobs, and we don't quote it like it is.

One flat rate

$441 per window, whatever the size. A building with thirty different window dimensions is still $441 each — no measuring by united inches, no size tiers.

We coordinate tenants

We handle unit-by-unit access directly with residents — the scheduling calls, the reminders, the reschedules. You aren't the middleman.

Quote in 24 hours

Send your window count and we return a per-building number within a day. No site visit required to get a real figure you can put in a budget.

Energy efficient

Double-pane low-E glass is standard on every window we install. Better insulation means a lower heating and cooling load for the building, and fewer tenant complaints about drafts and cold rooms.

How pricing usually works

Why do most “per window” prices have a size cap?

Because bigger glass costs more to make, advertised packages are usually limited by united inches — width plus height, totalled across the job. Go over the cap and surcharges appear. Our $441 has no cap.

Advertised window packages are typically limited by united inches — the width plus the height of each opening, added up across the job. Stay under the cap and you pay the advertised price. Go over it, and surcharges appear on the invoice.

A cap of 500 united inches across ten windows allows about 50 inches each — roughly a 24″ × 26″ opening. A standard apartment bedroom window is 48″ × 36″, or 84 united inches. Most real buildings are over the cap before the first unit is measured.

Our $441 has no cap. Bedroom, bathroom, or an eight-foot living room slider opening — the number does not move.

How it works

No runaround, no discovery calls before you get a number.

Address, approximate window count, and whether you need windows, patio doors, or both. Two minutes on the form below.

02

Get a flat-rate quote

Within 24 hours you receive a fixed per-building total based on your window and door count. One number, not a range.

03

We handle the rest

On approval we schedule tenant access, take precise field measurements, order, and install. You get progress updates, not phone calls to field.

What we install

What do you install?

Common questions

Common questions about apartment window replacement

Is $441 really the price for any window, regardless of size?
Yes. Standard residential windows — single hung, double hung, sliders, casement — are all $441 installed. The price doesn't change based on the size of the opening, and there is no united-inch cap. Structural modifications and historic-designation buildings are the exceptions, and we quote those separately.
What's included in the $441, and what isn't?
Included: the window unit, all hardware, installation labor, trim work, cleanup, and disposal of the old windows. Not included: structural modifications, opening resizing, stucco or siding repair beyond the retrofit trim, and historic-designation requirements.
Do I need to be on site when the work is done?
No. Most property managers hand us the tenant contact list and let us coordinate directly. We schedule unit by unit, confirm access, and send progress updates.
How long does a building take?
It depends on unit count and tenant availability. A 10-unit building typically completes in one to two days of install time. A 50-unit building runs closer to a week. Each individual unit is only open for a few hours.
Do you work on occupied buildings?
Yes — the majority of our projects are occupied. Retrofit installation is what makes this practical: we work within the existing opening, so there's no demolition of surrounding drywall or stucco and no unit is left open overnight.
Do you pull permits?
Most California jurisdictions do not require permits for like-for-like window replacement in existing residential buildings. Where a permit is required, we tell you before the work is scheduled. Requirements vary by city, so we confirm against the local building department for your address.
My building has a mix of window sizes. Is it still flat-rate?
Yes. A building with thirty different window sizes is still $441 per window. That is the entire point of the flat rate — you don't need a measurement schedule to get a number you can budget against.
What products do you install?
Commercial-grade vinyl and aluminum retrofit windows from established manufacturers, with double-pane low-E glass as standard. The specific product is matched to the building — its frame type, opening sizes, and exposure.
Do new windows actually reduce energy costs?
Older single-pane aluminum windows are one of the weakest points in an apartment building's envelope — they conduct heat straight through the frame and leak air around a worn seal. Double-pane low-E glass adds an insulating air gap and a coating that reflects radiant heat, so units hold their temperature longer and the HVAC runs less. How much that saves depends on the building, its exposure, its heating and cooling systems, and how the units are occupied, so we don't quote a percentage. The consistent, reportable results are fewer drafts, fewer temperature complaints, and less outside noise.
Is there a minimum building size?
No formal minimum. We've done duplexes and we've done 100+ unit complexes. Small buildings of two to four units are welcome — the flat rate works the same way at any scale.
What areas of California do you serve?
All of California. We have crews based in Southern California — Los Angeles, Orange County, the Inland Empire and San Diego — and in Northern California covering the Bay Area, Sacramento and the Central Valley.
