Every job is priced as a complete package, not a stripped-down number with add-ons tacked on later. Here is what is covered on a standard aluminum window replacement, and what we handle separately if your home needs it.
We measure every opening with a tape measure and level, and we check the rough framing for rot, water staining and out-of-square corners. If the opening needs repair, you hear about it before we order anything, not on install day.
Your unit arrives sized to the opening with the glass package you chose, whether that is dual-pane low-E with argon gas or laminated glass for noise. Screens and hardware come with it. We confirm the order against the measurements before it ships.
We pull the old aluminum unit, haul it away and sweep the area. No pile of old frames in your driveway, no dumpster you have to rent. All debris leaves with our crew on the same day.
Setting blocks, shims, insulation, flashing tape and silicone caulk go in on every opening. We seal the interior and exterior perimeter and verify the sill drains. This is the step that decides whether the window lasts or leaks.
We pull the permit and schedule the inspection. You do not stand in line at the city office or chase paperwork. When the inspector signs off, we hand you the closed permit and your warranty documents.
We test every sash with you, show you how the locks, screens and tilt features work, and leave you the written workmanship warranty plus the manufacturer's product warranty. If something is not right, you call us and we come back.
Aluminum Window Replacement Los Angeles CA is the removal of an existing aluminum window unit and the installation of a new frame, sash and glazing package that meets current California energy code. On a typical job we pull the old frame, check the rough opening for rot or water damage, set the new unit on window setting blocks, shim it level, insulate the gap and seal it with flashing tape and silicone caulk. Most single windows take two to four hours; a whole-house swap runs two to four days.
Los Angeles homes punish bad windows. Afternoon sun bakes west-facing glass past 140 degrees, marine air pushes salt and moisture inland from Santa Monica, and winter nights drop into the 40s in the Valley. When a seal fails you get foggy glass and condensation between panes; when the frame warps you get sticking windows and water leakage at the sill. If you have been searching for aluminum window replacement near me Los Angeles, the fix is a modern unit with low-E glass and argon gas.
No mystery, no surprise line items. Here is exactly what happens from the first phone call to the final walkthrough, whether you are replacing one bedroom window or all 18 in the house.
Schedule
Call or book online — a real human picks up and confirms a 2-hour arrival window.
Diagnose
Licensed tech inspects on-site, then walks you through the cause and your options.
Fix
The job is completed to code and done right the first time — no shortcuts, no surprises.
Guarantee
Every job backed by a written workmanship warranty — and we stand behind it.
Tape measure and 4-foot level
Used at measure and again at install to confirm the opening is square and the new unit sits level. An out-of-level window will not slide right and will leak at the low corner.
Pry bar and utility knife
For clean removal of the old unit and trim without damaging the surrounding stucco or drywall. Careful demo saves you patching and painting later.
Caulking gun with silicone caulk
Seals the interior and exterior perimeter. Silicone holds up to Los Angeles sun and marine air better than latex, which cracks within a couple of seasons.
Flashing tape
Creates the water-shedding layer at the sill and jambs. This is the single most important detail on an exterior window and the one most often skipped.
Window setting blocks and shims
Hold the unit off the sill so it drains and keep it plumb and level. Shims go at the correct load points so the frame does not bow over time.
Drill and screwdriver set
For anchoring the frame, fitting hardware and adjusting rollers on sliders. We torque to spec so nothing strips or backs out.
Insulation gun
Fills the gap between the rough opening and the new frame. Proper insulation stops air infiltration and cuts noise, and it has to be packed, not stuffed.
AAMA installation standards
We follow the American Architectural Manufacturers Association guidance for flashing, shimming and sealing. That means a sill pan, correct lap sequencing on the flashing tape and a drained rough opening, not just a bead of caulk around the frame.
NFRC-rated glass selection
Every glass package we sell carries a National Fenestration Rating Council rating for U-factor and solar heat gain. We match the rating to the window's orientation, so west-facing units get more heat rejection than north-facing ones.
ENERGY STAR and Title 24 compliance
California energy code sets minimum performance for replacement windows. We spec units that meet it, which keeps your permit clean and your inspection passing on the first visit.
Retrofit versus full frame decision
We check the existing frame before recommending either. If the frame is solid and square, retrofit saves you money and time. If it is rotted or out of square, full frame is the only fix that will not leak.
01
What we do: We measure every opening, check the framing for the rot that is common in homes this age, and quote both retrofit and full frame options so you can see the cost difference. Most buyers do the whole house at once before moving in.
→ New windows, a cooler house and a lower power bill from day one, plus the work is done before furniture arrives.
02
What we do: We replace just those units with low-E glass rated for high solar heat gain, and we check the other west-facing windows while we are there. You do not have to do the whole house to fix the worst offenders.
→ Clear glass, less heat coming through the west wall and a much smaller bill than a full-house job.
03
What we do: We size the opening to the code requirement, order a unit that meets it, pull the permit and install it with proper flashing. We coordinate with your contractor if other trades are on site.
→ A permitted, code-compliant egress window that passes inspection and gives you a safe escape route.
04
What we do: We install laminated or dual-pane glass with tight weatherstripping and seal the perimeter properly. Glass thickness and the air gap do most of the work, and the seal stops the rest of the sound leak.
→ A bedroom quiet enough to sleep in, with traffic noise cut down to a background hum.
Los Angeles is not one climate, it is several packed into one county. The San Fernando Valley hits triple digits in summer and drops into the 40s on winter nights, while Santa Monica and the coastal ZIPs stay mild but get salt air that eats hardware. Inland homes in Pasadena and Sylmar see bigger temperature swings than the Westside, which is why we spec different glass packages depending on where you are. Building stock matters too. Spanish bungalows from the 1920s and 30s often have odd-sized openings and stucco that hides old water damage, while 1960s ranches in Woodland Hills and Northridge usually have standard aluminum sliders that retrofit cleanly. California energy code applies to every replacement, so we pull permits and install to Title 24 performance minimums. If you have been looking for aluminum window installation company Los Angeles homeowners trust for both coastal and Valley properties, the answer is a crew that adjusts the spec to the address, not one that sells the same window everywhere.
Sherman Oaks
Mix of 1950s ranches and newer builds. Many homes still have original aluminum sliders that retrofit cleanly, and west-facing rooms need high heat-rejection glass.
Santa Monica
Marine air corrodes hardware and weatherstripping faster than inland. We spec stainless rollers and hardware rated for coastal exposure, and we check for salt damage at the sill.
Woodland Hills
Summer heat pushes past 100 degrees regularly. West and south-facing windows here get the strongest glass package we carry, with maximum solar heat gain rejection.
Pasadena
Older housing stock with character windows and some historic considerations. We match profiles to the original look where the home calls for it and handle the permit details.
North Hollywood
Lots of street-facing bedrooms near busy boulevards. Laminated glass and tight sealing make the biggest difference for noise on these jobs.
Intense afternoon sun on west-facing glass
Surface temperatures on single-pane aluminum climb well past 140 degrees, which warps frames and cooks the room behind them. Low-E glass with a low solar heat gain coefficient is the fix.
Marine air and salt exposure near the coast
Standard hardware and caulk break down faster in coastal ZIPs. We use silicone caulk and corrosion-resistant hardware so the window still operates smoothly after several seasons.
Winter rain and old stucco flashing
Aging stucco homes often have no sill pan behind the window. When we open the wall we install proper flashing, which is what stops the leaks that show up every January.
Valley temperature swings from hot days to cold nights
Frames expand and contract daily, which works seals loose over time. Thermally broken frames and quality weatherstripping hold up better under that cycle.
Aluminum windows fail in predictable ways, and each one points to a different fix. Here are the four calls we get most often and what is actually going on when you make them.
Problem
The seal is broken and moisture is inside the unit. You cannot clean it out, and the glass no longer insulates. Left alone, the frame and sill start to sweat and stain.
Our Fix
We replace the failed unit with a new dual-pane assembly using low-E glass and argon gas. If the frame is still sound, a sash replacement saves money. If the seal failure has spread to the frame, we go full unit.
Problem
Air moves through dried weatherstripping and gaps around the frame. Your air conditioner runs longer, and rooms on the west side never quite cool down in summer.
Our Fix
We install new units with fresh weatherstripping and insulate the perimeter gap properly. Combined with low-E glass, most homes see a real drop in cooling load. We also check for gaps at the sill where air sneaks in.
Problem
Aluminum frames warp and the tracks fill with grit. A window you cannot open is a ventilation problem and, in a bedroom, a safety problem. Forcing it cracks the glass or bends the sash.
Our Fix
If the frame is straight, we replace the sash and hardware and true up the tracks. If the frame itself is warped, a new unit is the fix. We test every window for one-hand operation before we leave.
Problem
Water gets behind the flashing and into the wall cavity. Drywall stains, framing rots, and the damage spreads past the window. This is the most expensive problem to ignore.
Our Fix
We open the wall, replace any rotted framing, install a proper sill pan and flashing tape, then set the new window and seal it. We have done this on hundreds of Los Angeles stucco homes where the original flashing was never correct.
Old aluminum frames conduct heat straight into your living room. New thermally broken units with low-E glass cut that transfer, tighten the envelope and make the whole house quieter. Here is what changes after the swap.
Lower Cooling Bills
Single-pane aluminum glass carries almost no insulation value. A dual-pane unit with low-E glass and argon gas blocks a large share of solar heat gain, so your air conditioner cycles less from June through October. Most Los Angeles homeowners notice the difference on the first hot week after aluminum window replacement in Los Angeles, California.
No More Foggy Glass
Fog between panes means the seal is gone and the unit is done. Once moisture gets inside, no amount of cleaning fixes it. We replace the whole unit so you get clear glass, full visibility and a fresh seal rated under NFRC test standards instead of a temporary patch.
Quieter Rooms
Aluminum transmits sound. If you live near the 101, the 405 or a busy boulevard in North Hollywood, you hear every truck. Laminated or dual-pane glass with tight weatherstripping knocks traffic noise down measurably, which matters most in bedrooms and home offices facing the street.
Stops Water Leakage
Failed flashing and dried-out caulk let rain into the wall cavity, where it rots framing and stains drywall. We install new flashing tape, shims and a proper sill pan so water drains out instead of soaking in. That is the difference between a window that lasts 20 years and one that leaks in year three.
Google ★★★★★4.9
Straightforward from the first call. They measured, gave us a written price the same day and did not try to upsell us into windows we did not need. Install crew was on time, covered the floors and cleaned up every scrap. Sixteen windows done in three days.
Yelp ★★★★★4.8
We had a leaking window that two other companies wanted to fix with caulk. These guys opened the wall, found the missing flashing and fixed it properly. Cost more than the caulk quote and worth every penny. No leak through the whole rainy season.
BBB A+
Permit, inspection, warranty paperwork, all handled without us chasing anything. The crew walked us through every window at the end and showed us how the tilt-in sashes work. Professional operation from start to finish.
Real experiences from customers who chose our Aluminum Window Replacement services.
“We had 11 original aluminum windows from 1962 and every one fogged up. The crew measured on a Tuesday and had pricing to us that night. Install took two days, they covered the floors, and they hauled off every old unit. Our upstairs bedrooms are noticeably cooler now and the street noise from Ventura Boulevard is way down.”
Marisol R.
Homeowner, Sherman Oaks
“Two windows on the west side of the house had water coming in at the sill every winter. Turned out the flashing was never done right. They rebuilt the opening, added a sill pan and set new units. We went through a full rainy season with zero leaks. Fair price and they cleaned up better than they found it.”
Dennis K.
Homeowner, Woodland Hills
“Condo job, so I was worried about HOA rules and noise. They handled the paperwork, used insert units so there was almost no dust, and finished in a day and a half. The salt air had eaten the old hardware, so the new locks and rollers feel solid. Worth every dollar.”
Priya N.
Condo Owner, Santa Monica
Real answers to the questions we hear most often from local homeowners and property managers.
When the rough opening is rotted or out of square, a full frame replacement is the only correct fix. We remove the entire old frame down to the studs, rebuild the opening and set the new aluminum unit. Common in older Los Angeles stucco homes where water has been getting in for years.
View Full Frame Window ReplacementRetrofit keeps your existing frame and drops a new unit inside it. It is faster and less expensive than full frame, and it works well when the original aluminum frame is still solid. Most Los Angeles homes built after 1970 are good candidates for retrofit.
View Retrofit Window ReplacementAn insert window fits inside the existing jamb with minimal tear-out, so there is less dust and less patching afterward. It is a good match for condos and apartments where you want new glass performance without disturbing interior trim or exterior stucco.
View Insert Window ReplacementIf the frame is fine but the sash is warped or the glass seal failed, replacing just the sash saves money. We match the profile to your existing aluminum frame and swap the moving parts. It is the least invasive option when only part of the window has failed.
View Window Sash ReplacementBoth sashes slide on a double hung, which makes cleaning second-story windows easier and gives you better airflow control. We install tilt-in sashes so you can clean from inside. Popular in Los Angeles two-story homes and anywhere you want ventilation without screens in the way.
View Double Hung Window ReplacementOne fixed upper sash, one sliding lower sash. Single hung is the workhorse for bedrooms and hallways, and it costs less than double hung. If you are replacing a whole house on a budget, mixing single hung in secondary rooms keeps the total down.
