What Our Storm Window Replacement Includes
Every storm window replacement job we run includes the full scope below. If your project needs something outside this list, we tell you before we start and price it separately so there are no surprises on install day.
Custom Panel Build
We order your storm panels built to the actual opening, not a stock size. Vinyl, aluminum, wood, and composite options are available, with low-E glass and argon gas fills on request.
Full Removal and Install
We pull the old units, check the rough opening, set the new panels with shims and window setting blocks, and level each one. A typical house takes 4 to 8 hours.
Sealing and Flashing
We seal the perimeter with silicone caulk, add flashing tape at the head and sill, and run weatherstripping at the sash. That is what stops the drafts and the water leaks.
Walkthrough and Warranty
We open and close every window with you, test for air leaks, and hand over care instructions plus our written workmanship warranty. If anything is off, we fix it before we leave.
Storm Window Replacement Los Angeles CA Explained
Storm Window Replacement Los Angeles CA is a window upgrade that adds a second layer of glass or acrylic over your existing window to block wind, rain, noise, and heat transfer. We measure the opening, build the storm panel to fit within an eighth of an inch, then seal it with weatherstripping and silicone caulk so nothing gets past it. Most homes get a full set done in one day.
Los Angeles homes deal with Santa Ana winds, coastal fog, and summer heat that pushes 100 degrees in the Valley. Older single-pane windows leak air at the sash and frame, which drives up your energy bill and lets street noise inside. If you have been searching for storm window replacement near me Los Angeles, we serve 91367, 90291, 90293, and the rest of the city with same-week scheduling.

Tools and Methods We Use
Tools & Equipment
Tape measure and level
We measure every opening to the eighth of an inch and check the frame for square before we order. A frame that is out of level gets shimmed during install.
Pry bar and utility knife
Used to pull the old storm panels and trim without damaging the surrounding stucco or interior casing. We cut the old caulk line clean before removal.
Caulking gun and silicone caulk
We seal the perimeter of every panel with silicone caulk, which stays flexible through the temperature swings we get in Los Angeles.
Insulation gun and flashing tape
Flashing tape goes at the head and sill to shed water. The insulation gun fills any gap between the panel and the rough opening before we close it up.
Window setting blocks and shims
These keep the panel centered and level in the opening so the sash operates smoothly and the seals stay tight over time.
Drill and screwdriver set
We fasten the panels and the hardware with the correct bits for the frame material, whether that is vinyl, aluminum, wood, or composite.
Methods & Standards
AAMA and WDMA installation standards
We follow the AAMA and WDMA installation guidelines on every job. That covers the flashing sequence, the fastener spacing, and the sealant placement. It is the difference between a window that lasts 20 years and one that leaks in year three.
ENERGY STAR and NFRC rated glass
We offer low-E glass and argon gas fills that carry ENERGY STAR and NFRC ratings. The NFRC label tells you the U-factor and solar heat gain so you can compare options. In Los Angeles, low-E glass helps most on west-facing walls.
Flashing tape sequence
We run flashing tape at the sill first, then the jambs, then the head, so water sheds outward at every layer. Skipping that order is the most common cause of leaks we see on repair calls.
Smoke pencil air-leak test
At the walkthrough we run a smoke pencil around the perimeter and the sash to find any air movement. If we see smoke pull, we reseal before we leave. It is a fast check that catches problems on the spot.
When to Call for Storm Window Replacement
01
You bought a 1950s Valley ranch with original single-pane windows and the first winter bill shocked you.
What we do: We measure every opening, install storm panels with low-E glass, and seal the frames. We also check for rotted sills while we are in there and repair what we find.
→ Lower heating and cooling costs, quieter rooms, and no more drafts near the glass.
02
You live near a freeway or a busy street and the traffic noise wakes you up at night.
What we do: We install storm windows with tight perimeter seals and weatherstripping at the sash, which is where most sound leaks through. Bedroom windows get priority on the schedule.
→ Outside noise drops by 50 to 70 percent and the bedrooms become usable again.
03
Two windows have fog between the panes and one frame has soft wood at the sill.
What we do: We replace the failed units, repair the sill, add flashing tape, and caulk the perimeter. If the frame is sound, a storm panel over it restores performance without a full replacement.
→ Clear glass, a dry wall, and a sealed frame that holds up through the rainy season.
04
You are selling the house and the home inspector flagged the windows as drafty and hard to operate.
What we do: We do a fast measure, order standard panels, and install them before your contingency period ends. We provide the paperwork for the buyer and the agent.
→ The inspection item clears and the house shows better to buyers.
How Storm Window Replacement Runs in Los Angeles
Los Angeles is not one climate. Santa Monica and the coastal ZIPs like 90291 deal with salt air and fog that corrodes hardware and works into seals. The Valley, from Woodland Hills to Sylmar, swings from 40 degrees in January to over 100 in July, which expands and contracts frames until the caulk line cracks. Older housing stock matters too. A 1925 bungalow in Sherman Oaks often has wood frames that need sill repair before a storm panel goes on, while a 1965 ranch in Northridge usually has aluminum sliders that just need new rollers and a tight seal. We pull permits when the scope requires it and meet the inspector on site. If you need storm window installation Los Angeles homeowners can schedule around a work week, we book installs Tuesday through Saturday. For anyone searching Storm Window Replacement Los Angeles County near me, we cover the city and the surrounding areas with the same crew and the same standards.
Neighborhoods We Serve
-
Sherman Oaks
Lots of 1940s and 1950s homes with original wood frames. We check for sill rot before quoting because the wood takes water at the end grain.
-
Woodland Hills
Summer heat pushes past 100 degrees, so west-facing windows take a beating. Low-E glass and argon fills make the biggest difference here.
-
North Hollywood
Freeway noise from the 101 and the 170 is a common complaint. Storm panels with tight perimeter seals are the fix most customers ask for.
-
Santa Monica
Salt air corrodes hardware and works into seals. We use stainless fasteners and check the weatherstripping on every unit near the coast.
-
Pasadena
Many Craftsman homes with wood frames that need painting and sealing. We match the trim profile so the storm panel does not change the look.
Local Conditions We Plan For
-
Santa Ana wind events each fall
Wind-driven debris and pressure changes find every gap in a failed seal. We install panels with tight perimeter caulking and check the sash locks before we leave.
-
Coastal fog and salt air
Hardware corrodes faster near the coast. We use stainless fasteners and silicone caulk that holds up to moisture without cracking.
-
Valley temperature swings of 60 degrees or more
Frames expand and contract until the caulk line fails. We use flexible silicone and check the seal at the walkthrough with a smoke pencil.
-
Winter rain events that dump an inch in a day
Water finds rotted sills fast. We repair the sill and run flashing tape at the head and sill so water sheds away from the wall.
Sherman Oaks Bungalow, 11 Windows
Storm Window Replacement Los Angeles CA Problems We Fix
Most of our calls come down to four issues: drafts, fog, noise, and water. Here is what each one means and how we solve it.
Problem
Drafty windows that make rooms cold in winter
Air leaks force your furnace to run longer, which raises the bill and leaves rooms uneven. Cold spots near the glass are the first sign.
Our Fix
We install storm panels with weatherstripping at the sash and silicone caulk at the frame. That second layer of glass stops the air movement. Most customers feel the difference the first cold night after install.
Problem
Condensation between panes and foggy glass
Fog means the seal has failed and moisture is inside the unit. The glass will not clear on its own and the insulation value drops to near zero.
Our Fix
We replace the failed unit and reseal the frame. If the sash is still sound, a storm panel over it restores the insulation value at a lower cost than a full window replacement.
Problem
Street noise coming through single-pane glass
Homes near the 101, the 405, or a busy commercial street get constant traffic noise. It disrupts sleep and makes a home office hard to use.
Our Fix
Storm windows cut outside noise by 50 to 70 percent. We install panels with tight perimeter seals and weatherstripping, which is where most of the sound leaks through. Bedrooms and offices benefit the most.
Problem
Water leakage at rotted window frames
Driving rain finds every gap in a rotted sill. Water soaks into the wall, stains drywall, and can reach the framing if it is not stopped.
Our Fix
We repair the sill, add flashing tape at the head and sill, and caulk the perimeter with silicone. That sheds water away from the wall instead of letting it soak in. We check the frame for rot before we quote the job.
Why Homeowners Upgrade Their Storm Windows
Storm windows are not a cosmetic upgrade. They change how your house feels, sounds, and performs. Here is what our customers notice within the first week.
-
Lower Energy Bills
A second pane cuts heat loss through the glass by up to 50 percent. In a Valley home running central air from June through September, that shows up as real savings. We install low-E glass and argon gas fills on request for even better performance.
-
Quieter Rooms
Storm windows knock down outside noise by 50 to 70 percent. If you live near the 101, the 405, or a busy commercial street in North Hollywood, that difference is the reason most of our customers call. Bedrooms and home offices benefit the most.
-
No More Foggy Glass
When seals fail, moisture gets between the panes and you get permanent fog. Storm window replacement services Los Angeles CA homeowners trust fix that by replacing the failed unit and resealing the frame. You get clear glass and a tight seal again.
-
Stops Water Leaks
Driving rain finds every gap in a rotted frame. We replace the flashing, add shims where the sill is out of level, and caulk the perimeter so water runs off instead of soaking into your wall. That protects your drywall and your framing.

Measured 11 windows, gave a written price, and installed in one day. The crew was on time and cleaned up. Our Sherman Oaks house is quieter and the furnace does not run as long. Would use them again.
Yelp ★★★★★4.8
We had fog in three windows and rot in one sill. They fixed the sill, replaced the units, and sealed everything. No more water stain on the drywall. Fair price and no pressure to buy more than we needed.

Frequently Asked Questions
Real answers to the questions we hear most often from local homeowners and property managers.
How much does Storm Window Replacement cost in Los Angeles?
Most storm window replacement jobs in Los Angeles run $250 to $650 per window installed, with a typical whole-house project landing between $3,000 and $9,000. The price depends on the panel material, glass type, and how much frame repair is needed. Vinyl and aluminum panels sit at the lower end; wood and composite frames with low-E glass sit higher.
What is storm window installation in Los Angeles CA?
Storm window installation in Los Angeles CA adds a secondary panel over your existing window to block air, water, and noise. We measure the opening, build the panel to fit, then seal it with weatherstripping and silicone caulk. It is a faster, lower-cost alternative to a full window replacement when your existing frames are still solid.
Who offers Storm Window Replacement near me in Los Angeles?
American Reliable Windows & Doors offers storm window replacement across Los Angeles County, including Sherman Oaks, Woodland Hills, North Hollywood, Santa Monica, Pasadena, and Beverly Hills.

Are storm windows necessary in Los Angeles?
They are not required by code, but they pay off in Los Angeles. Single-pane windows lose heat in winter and let heat in during summer, and our coastal fog and Valley winds push air through every gap. Storm windows cut that air movement, reduce street noise, and stop water from reaching rotted frames. Most homeowners notice the difference in the first week.
Related Services
Full Frame Window Replacement
When the frame itself is rotted or out of square, a full frame replacement is the right call. We pull the entire unit down to the rough opening, rebuild the sill, and install a new window. Storm panels go on top of a solid frame, so this is the fix when the frame is gone.
View Full Frame Window ReplacementRetrofit Window Replacement
Retrofit replacement fits a new window into the existing frame without disturbing the stucco or trim. It pairs well with storm window replacement because both work off a sound existing opening. We measure the frame, order the retrofit unit, and seal it the same day.
View Retrofit Window ReplacementInsert Window Replacement
Insert windows drop into the existing jamb and leave the interior and exterior trim untouched. If your frames are solid and you want a cleaner look than a storm panel, this is the option. We handle the measure, the insert, and the perimeter seal in one visit.
View Insert Window ReplacementWindow Sash Replacement
Sometimes only the moving sash is worn out and the frame is fine. Sash replacement swaps the operating section and keeps the rest of the window. It is a lower-cost path when you have sticking sashes or broken seals but no frame damage.
View Window Sash ReplacementDouble Hung Window Replacement
Double hung windows open from the top and bottom, which helps with airflow in older Los Angeles homes without central air. We install them with low-E glass and argon gas fills on request. Storm panels can be added over double hung units for extra noise control.
View Double Hung Window ReplacementSingle Hung Window Replacement
Single hung windows have a fixed top sash and an operating bottom sash. They are common in mid-century Valley homes and cost less than double hung units. We measure the opening, set the new frame, and seal it against the wind-driven rain we get each winter.
