Fast, Reliable Window Replacement Across Los Angeles

Window replacement in Los Angeles runs $450 – $1,100 per window for standard vinyl inserts, $800 – $2,600 per opening for full-frame jobs, and $700 – $2,200 for impact-rated units that require engineering review. Most LA homeowners complete between 5 and 12 windows at once, so a realistic project budget is $4,000 – $14,000 for a typical single-family home, with full-house replacements on larger Spanish Colonials or Mid-Century Moderns running $18,000 – $35,000. We schedule Los Angeles estimates within 48 hours and most non-permitted insert jobs go from measure to install inside two weeks.

We’re Juniper Windows & Doors, led by Sean Mackey. Our crews know LA’s housing stock the way a local does, because we work it every week: 1920s bungalows in Highland Park, 1950s stucco ranches in Lakewood, hillside Spanish Colonials in Los Feliz. Call (682) 281-2168 for a free estimate with a written price before anything starts.

Why Juniper Windows & Doors Is Los Angeles’s Preferred Window Replacement Company

The Relay Visibility Guarantee is the reason LA homeowners keep our number. You book, we confirm a live arrival time you can track like a rideshare. Your installer is background-checked and arrives in uniform. You get before-and-after photos of every opening, a written line-item price before work begins, and a digital invoice you can pay from your phone. No four-hour windows. No no-shows. No “we’ll have to see once we open the wall.”

Every Los Angeles project is covered by the 365-Day Done Right Promise: if the work isn’t right, we fix it. Twelve months. Parts and labor. In writing. That’s not a slogan; it’s on every proposal we send in LA.

Founded in 2001 as part of the Relay Home Co. family, Juniper carries eight product lines: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That matters in Los Angeles because a hillside home in El Sereno may need impact-rated glazing with a design pressure calc, while a Craftsman in Eagle Rock might call for a wood-alternative frame that matches original sightlines. One product line can’t do both well. We’re not married to one brand, so the right window is never a compromise.

For a deeper look at what’s involved, see our Window Replacement hub. And because every city’s market is different, our Window Replacement in Los Angeles page explains why local experience here moves the needle more than any national ad campaign ever could.

Window Seal Repair in Los Angeles

Window seal repair in Los Angeles typically runs $150 – $400 per window when the frame is still square and the sash is intact, though many LA homeowners choose to replace the insulated glass unit (IGU) entirely at $300 – $700 per window for a longer-lasting fix. A failed seal shows up as fog, haze, or moisture trapped between two panes of glass. In LA, seal failures are common on homes built between the 1980s and early 2000s, when Low-E coatings were standard but edge seals were thinner and broke down faster.

What We Actually Fix

Seal repair isn’t a glue patch. We remove the sash, disassemble the frame, replace the IGU, and rebuild the seal with fresh desiccant and a proper edge bond. For wood-frame windows in Los Angeles bungalows, we’ll sand and reseal the glazing channel while the sash is out. If the frame itself has twisted, no seal replacement will hold, and we’ll tell you that before you spend money on a fix that fails in a year.

When to Repair vs. Replace

If the window is under 15 years old and the frame is plumb, seal repair usually makes sense. If you’re seeing condensation, drafts, and heat radiating through the glass in August, a full Window Replacement likely costs less over five years than chasing seals one at a time. We’ll give you both numbers in writing and let you decide.

Energy Efficient Windows in Los Angeles

Energy efficient windows in Los Angeles cost $600 – $2,400 per opening depending on frame material, glass package, and whether you’re doing inserts or full-frame replacement. The real question for LA homeowners isn’t “how much do they cost” but “which glass package actually works in my microclimate.” A Low-E coating that performs in Santa Monica’s marine layer will cook a San Fernando Valley living room. We spec by orientation and ZIP code, not by default.

SHGC by Orientation: Why It Matters Here

Because Los Angeles spans the cool coast and the hot inland valleys, solar heat gain coefficient (SHGC) isn’t a one-number decision. West-facing glass in Sherman Oaks takes direct afternoon sun and needs a SHGC around 0.23 to stop heat gain. North-facing glass in Mar Vista barely sees direct sun, so you want a higher SHGC to let winter warmth in. We pull glass spec sheets for every opening before we write the estimate.

In the San Fernando Valley, we typically recommend PGT’s Low-E insulated glass with a lower SHGC on south and west elevations. Closer to the coast, in neighborhoods like Palms or Westchester, we often step up to a moderate SHGC package that balances glare control without making the house feel like a cave. Juniper has carried PGT, CGI, and CWS for years, and we stock replacement sashes and IGUs for all three at our Los Angeles warehouse, which cuts turnaround time when a single window needs matching glass.

Trusted Brands We Service in Los Angeles

We install and service PGT, CGI, and CWS windows throughout Los Angeles, and we keep parts for all three on hand locally. That means if a PGT impact-rated unit in a Venice Beach bungalow loses a seal or a CWS casement crank in a Silver Lake Hillside home strips out, we don’t wait two weeks for a factory order. We pull from our Los Angeles inventory and get it done. We also work with Window Replacement projects that involve wood-clad or fiberglass lines, and we’ll match existing millwork when you’re replacing a few windows rather than the whole house.

Common Window Replacement Problems We See in Los Angeles Homes

  • Undersized rough openings in pre-war bungalows. Los Angeles has tens of thousands of homes built between 1900 and 1940, and their rough openings were framed for sashes that aren’t made anymore. If you measure only the visible opening and ignore the rough opening depth, the new frame either protrudes past the stucco or leaves a gap that needs on-site framing. We measure to the rough opening on every LA job.
  • Wrong permit path for hillside or coastal properties. An over-the-counter LADBS permit works for most of Los Angeles, but a hillside ordinance zone in Mount Washington adds plan review and a separate inspection sequence. Coastal properties along the Venice or Playa del Rey boundary may trigger a Coastal Development Permit review. We handle this every week, and we won’t let a homeowner start without the right paperwork.
  • Single glass package specified for every window in the house. A west-facing window in Woodland Hills and a north-facing window in West LA need different SHGC values. Using the same Low-E spec everywhere can block winter sun on the north side or let the house bake on the west side. We spec glass per elevation, not per house.
  • Forgetting that old LA frames were built for single-pane glass. Many 1920s – 1950s Los Angeles homes have jamb depths that don’t match modern replacement frame dimensions. On a full-frame job we can rework the jamb cleanly, but on an insert job the frame either sits proud of the opening or requires a filler strip. We’ll show you photos of the jamb on measure day so there are no surprises.

Pricing for Window Replacement in Los Angeles, CA

Here are the numbers we give Los Angeles homeowners on a typical bid, and these are ranges, not guesses. Vinyl insert replacement runs $450 – $1,100 per window. Full-frame replacement (which most pre-1970 LA homes need) runs $800 – $2,600 per opening. Impact-rated windows, common for hillside ordinance zones and areas near LAX flight paths, run $700 – $2,200 per window, plus engineering if LADBS requires design pressure calculations. A standard 8-window insert job on a 1950s ranch in Lakewood typically lands between $4,500 and $9,000. A full-frame replacement on a 1920s Spanish Colonial in Angelino Heights can run $15,000 – $28,000 depending on stucco repair and trim work. Energy efficient upgrades add roughly $150 – $500 per window for premium Low-E packages. Call (682) 281-2168 and we’ll write a fixed price for your exact openings, no vague estimate that morphs at the door.
