"Got four quotes. Red Stag was middle on price but the only one that itemized the flashing system, named the installers, and gave me a paper warranty. Quote was $24,800. Final invoice was $24,800."

"Our 4-year-old windows from a big-box installer were rotting at the sill. Red Stag did the inspection free, told us exactly what corners had been cut, and replaced the worst six in two days. Israel handled the warranty fight on our behalf."

"1924 Pasadena Craftsman. Three other contractors wanted vinyl. Red Stag matched the muntin profile, used Andersen Woodwright, and the city historic board approved on first review. They knew which century I lived in."

Every opening · one crew

14 services. Single owner-supervised crew.

Single window swap or whole-home retrofit. We don't subcontract installation — the crew on your driveway is on Red Stag's payroll, paid hourly, not piece-rate.

The difference

If we install it,
we own it for life.

Industry installation warranty is twelve months. Ours doesn't expire. Below: the eight places we don't cut corners — the difference between a window job that lasts ten years and one that lasts forty.

MARVIN
Architect favorite

Modernist remodels with big openings, minimal sightlines.

PELLA

Whole-home swaps where lifetime glass coverage matters.

"I started Red Stag in 2011 because I got tired of fixing other people's installs."

Israel has been in the trade since 2011 — building Red Stag from the ground up after years of watching bad installs fail two winters in. Same story every time: corner-cut flashing, foam where backer rod should've been, no shims behind the strike plate.

Israel is on every job site at least twice — at measure, and at final walkthrough. If your install has a problem, his cell number is on your contract.

01How much does whole-home window replacement cost in LA?
For an 1,800–2,500 sq ft home: $14,000–$32,000 all-in for vinyl, $22,000–$48,000 for fiberglass, $35,000–$75,000 for clad-wood. Big variables: window count (most LA homes have 12–18), frame material, and full-frame vs retrofit. Use the calculator above for a tighter band in 60 seconds.
02How long does installation actually take?
Typical 12–14 window job: 2–3 days on site. Single window or door: half a day. We commit to same-day weatherproofing — every opening we pull is sealed back up before the crew leaves. We never tarp an opening overnight.
03Do I need permits? Who pulls them?
Yes — California requires a permit for any window or door replacement that affects size, U-factor, or framing. We pull the permit, file Title 24 docs, and meet the inspector on site. Included in your quote, not an add-on.
04How is your lifetime warranty different from other "lifetime" warranties?
Most "lifetime" warranties have 2-page exclusion lists: pro-rated after year 5, void if you sell, $300 trip charges. Ours is one page. If our install fails, we fix it on our dime, for as long as you own the home, transferable once. Only exclusion is impact damage — and that's what your homeowner's policy is for.
05What's the difference between retrofit and full-frame replacement?
Retrofit (block-frame) leaves your existing frame in the wall — faster, no stucco cut, but you lose ~1" of glass on each side. Full-frame removes the old frame to the rough opening — more labor, but you keep original glass area and we can fix any hidden water damage. We recommend full-frame on anything 25+ years old.
06Do you offer financing?
0% APR for 24 months on jobs over $5,000, or 7.99% fixed for terms up to 144 months on larger projects. Soft credit pull, decision in ~90 seconds, funds at install. We use GreenSky and Service Finance and don't pad pricing to cover dealer fees.
07What if I just need one window or door?
We take single-window and single-door jobs starting at $1,800 installed. Same warranty, same crew, same 48-hour quote. We don't turn down small work — it's how we earn the whole-home job five years later.
08Are your windows Title 24 compliant?
Every window we install meets or exceeds California Title 24 (typically 0.30 U-factor, 0.23 SHGC for LA climate zone). We submit the CF1R form with the permit and pin the CF2R label to your panel after install. If you're also doing solar or HVAC, we coordinate the energy modeling.
