What Our Double Hung Window Replacement Includes
Every job includes the full install, not just the window. We handle removal, disposal, sealing, and cleanup so you are not chasing down a second contractor for trim or haul-away. Here is what comes standard.
Flashing and Sealing
Flashing tape over the nailing fin, low-expansion foam around the perimeter, and silicone caulk inside and out. This is the water-management detail that keeps Los Angeles rain out of your wall cavity.
Shims and Setting Blocks
We set each unit on window setting blocks and shim it plumb and level before fastening. That is what keeps the sashes sliding smoothly years later instead of binding in the frame.
Hardware and Screens
New locks, tilt latches, and balances come with the unit, and we install fresh screens. We test every sash for smooth travel and confirm the locks engage before we call the job done.
Permit and Inspection
We pull the Los Angeles permit and meet the inspector on site. You get the signed-off paperwork for your records, which matters when you sell the house or file an insurance claim.
Full Cleanup
We vacuum the sills, wipe the glass, and walk the job with you room by room. If anything is not right, we fix it before we leave. Most customers say the house looks better than before we started.
What Double Hung Window Replacement Los Angeles CA Involves
Double Hung Window Replacement Los Angeles CA means removing both the upper and lower sash assembly, inspecting the frame and rough opening, then installing a new unit with fresh flashing, shims, and insulation. A double hung window has two operable sashes that slide up and down and tilt in for cleaning. We measure the opening with a tape measure at three points, check the sill for rot with a pry bar, and confirm the wall is square before anything gets ordered.
Most Los Angeles homes we open up were built between 1920 and 1970, and the original wood or aluminum frames have taken decades of sun, marine layer, and Santa Ana wind. That combination dries out weatherstripping, warps sashes, and breaks the seal between panes, which is why so many homeowners search for double hung window replacement near me Los Angeles once the foggy glass shows up. We see it in Encino, Northridge, and Santa Monica alike.

Tools and Methods We Use
Tools & Equipment
Tape measure and level
We measure each opening at three points and check plumb and level before ordering. A window ordered off one measurement is how jobs go wrong.
Pry bar and utility knife
Used to pull the old frame and trim without tearing up your drywall. We cut the caulk line clean so the new unit sits flat against the wall.
Caulking gun and silicone caulk
We run a continuous bead inside and out. Silicone holds up to Los Angeles sun better than painter's caulk, which cracks within a few seasons.
Insulation gun and low-expansion foam
Foam fills the gap between the window frame and the rough opening. Low-expansion foam will not bow the frame the way standard foam can.
Flashing tape
We tape the nailing fin and sill pan so water sheds outward. This is the single most important step for stopping leaks at the head and sill.
Window setting blocks and shims
Blocks support the unit at the correct height and shims hold it plumb. They keep the sashes from binding and the locks from drifting out of alignment.
Drill and screwdriver set
We fasten through the frame at the manufacturer's specified intervals. Correct fastener spacing is what keeps the unit from shifting in a Santa Ana wind.
Methods & Standards
AAMA installation guidelines
We follow the AAMA standard for flashing, shimming, and fastening. It is the accepted method for keeping water out of the wall, and it is what inspectors in Los Angeles look for when they sign off on the permit.
NFRC-rated glass packages
Every unit we sell carries an NFRC label listing U-factor and solar heat gain. We match the glass to the window's orientation, so a west-facing window gets a different package than a shaded north window.
ENERGY STAR and California code compliance
We spec units that meet ENERGY STAR and California energy code for the climate zone. That keeps you compliant and can qualify you for utility rebates on qualifying replacements.
Retrofit versus full frame
We choose the method based on the frame condition. A solid frame gets a retrofit, which is faster and cheaper. A rotted or out-of-square frame gets a full frame replacement so the new window has something solid to sit in.
When to Call for Double Hung Window Replacement
01
You just bought a 1950s Valley ranch house with original single-pane windows and want to cut summer cooling costs before next July.
What we do: We measure every opening, recommend a vinyl or fiberglass double hung unit with low-E glass and argon gas, and install with full flashing and insulation. We pull the permit and handle inspection.
→ The house holds cool air longer, the air conditioner cycles less, and the rooms are quieter. You also get the permit paperwork for resale.
02
Two upstairs bedroom windows are fogged and the sills feel soft when you press them.
What we do: We inspect the frame with a pry bar and level, photograph the rot, and quote the repair before we order. Then we replace the units and rebuild the sill with new flashing.
→ The fog is gone, the sill is solid, and water no longer tracks into the wall. The repair is documented for your records.
03
You are remodeling a kitchen and want a window that opens for ventilation but still seals tight against the afternoon sun.
What we do: We pair a double hung unit with an awning window over the sink, both with low-E glass. We coordinate the install with your contractor so the counter and backsplash go in after the window is set.
→ You get cross ventilation, a clear view, and a tight seal that keeps the heat out. The window is flashed and sealed before the tile goes up.
04
You rent out a duplex in North Hollywood and the tenants keep complaining about drafts and windows that will not lock.
What we do: We schedule the install between tenants, replace the units, and test every lock and sash. We pull one permit for the property and clean up the same day.
→ The complaints stop, the units lock properly, and the property is easier to lease. The work is warrantied, so you are not called back for the same issue.
How Double Hung Window Replacement Runs in Los Angeles
Los Angeles is not one climate, and we install accordingly. Coastal homes in Santa Monica and the 90291 ZIP deal with salt air and marine layer that corrode hardware and swell wood frames. Inland homes in Woodland Hills and Northridge hit triple digits in summer, so we spec low-E glass with a lower solar heat gain coefficient on west-facing windows. The Santa Ana winds push water sideways against the glass, which is why we flash the head and sill on every unit instead of relying on caulk alone. Building stock varies too: 1920s craftsman homes in Pasadena often need full frame replacement because the original wood has rotted, while 1960s tract homes in Reseda usually take a retrofit. We pull permits through the Los Angeles Department of Building and Safety and meet the inspector on site. If you are looking for double hung window installation cost Los Angeles pricing, we give you a firm number after measuring, not a range that moves.
Neighborhoods We Serve
-
Sherman Oaks
Mix of 1950s ranch homes and newer builds. Many original windows have single-pane glass and worn balances, so replacement delivers an immediate noise and comfort gain.
-
Santa Monica
Salt air corrodes hardware and weatherstripping faster than inland. We spec stainless or coated hardware and check the frame for swelling near the coast.
-
Pasadena
Craftsman and Spanish homes with original wood frames. Rot at the sill is common, so we plan for full frame replacement and trim matching.
-
Northridge
Inland heat drives the call for low-E glass and argon gas. West and south facing windows benefit most from a solar-control package.
-
Beverly Hills
Larger custom openings and stricter design review. We coordinate on trim profiles and finish colors so the new units match the elevation.
Local Conditions We Plan For
-
Inland summer heat above 100 degrees
Drives the need for low-E glass and argon gas to cut solar heat gain. Without it, the air conditioner runs longer and the room never fully cools.
-
Coastal marine layer and salt air
Corrodes hardware and swells wood frames. We use coated or stainless hardware and check the sill for moisture damage before installing.
-
Santa Ana winds and sideways rain
Pushes water against the glass and frame. Proper flashing tape at the head and sill is what keeps that water out of your wall.
-
Older housing stock with original wood frames
Raises the odds of rot at the sill, which means a full frame replacement instead of a retrofit. We inspect before quoting so there are no surprises.

Window Problems We Fix in Los Angeles Homes
Most calls start with one of these five complaints. All of them trace back to a failed seal, worn weatherstripping, or a frame that has taken too much sun and water.
Problem
Drafty windows that let cold air in at night
Your furnace runs longer, the room never feels warm, and the energy bill climbs every winter. Drafts also pull dust and pollen into the house.
Our Fix
We replace the unit and seal the perimeter with low-expansion foam and silicone caulk. New weatherstripping on both sashes closes the gap that was letting air through. Most customers feel the difference the first cold night.
Problem
Condensation and fog between the glass panes
The seal has failed, so the unit cannot be repaired. The fog blocks your view and the glass no longer insulates, which means heat gain in summer and loss in winter.
Our Fix
A new insulated glass unit with low-E glass and argon gas restores the rating and clears the view. We check the frame at the same time, because a failed seal often comes with water sitting in the sill.
Problem
Sticking or painted-shut sashes
You stop opening the window, so the room gets stuffy and you lose your emergency escape path. Forcing a stuck sash can crack the glass or bend the frame.
Our Fix
We replace the unit and install new balances so the sash moves with light pressure. Tilt-in sashes make cleaning easy, which is a big reason Los Angeles homeowners pick double hung over single hung.
Problem
Rotted window frames and sills
Soft wood lets water into the wall, which leads to mold, damaged stucco, and termite activity. The damage usually costs more than the window if you wait.
Our Fix
We open the wall, remove the rot, and repair the rough opening before setting the new window. Then we flash and seal it properly so the same spot does not fail again. We show you photos before and after the repair.
Problem
Street noise coming through the glass
Traffic, leaf blowers, and neighbors keep you up. Cheap single-pane glass does almost nothing to block sound, and worn weatherstripping makes it worse.
Our Fix
A double hung unit with insulated glass and tight weatherstripping cuts the noise path. We also seal the frame perimeter, which is where a lot of sound leaks in. Customers near busy streets notice the biggest change.
Why Homeowners Replace Double Hung Windows
New double hung units fix the problems you feel every day: the draft at your desk, the street noise at 6 a.m., the sash that won't stay up. Here is what actually changes after installation.
-
Lower Energy Bills
Low-E glass with argon gas between the panes blocks a large share of heat gain, which matters when inland Los Angeles hits 100 degrees in September. Paired with new weatherstripping and silicone caulk at the frame, most customers notice the air conditioner running less in the first cooling season.
-
Quieter Rooms
Broken seals and worn weatherstripping let traffic noise straight through. A properly shimmed, insulated double hung unit cuts that path. Homeowners near Ventura Boulevard and the 101 tell us they can finally sleep past the morning commute without a fan running for white noise.
-
Smooth, Safe Operation
Sticking windows are a safety issue, not just an annoyance. New sash balances let you lift a heavy upper sash with two fingers and hold it anywhere. Tilt-in sashes make cleaning the outside glass from inside the room, which is the reason many two-story Los Angeles homes choose double hung in the first place.
-
No More Foggy Glass
Condensation between panes means the seal failed and the unit cannot be repaired, only replaced. Once we install a new insulated glass unit, the fog is gone for good. We also check the sill and flashing so water leakage does not rot the frame behind your new window.

Measured on a Tuesday, installed the next week. Eight double hung windows, all sliding smooth, and they cleaned up every scrap of the old frames. The price matched the quote to the dollar. I would use them again.
Yelp ★★★★★4.8
They found rot at two sills and showed me photos before quoting the repair. No pressure, no upsell. The new low-E units cut the afternoon heat in my west-facing office noticeably. Good crew, showed up on time.
BBB ★★★★★5.0
I manage rentals and needed six windows replaced between tenants. They pulled the permit, finished in a day and a half, and every lock lines up. Tenants stopped complaining about drafts. Already referred them twice.
Google ★★★★★4.9
Foggy glass in four windows and a soft sill. They replaced the units, rebuilt the sill, and flashed it properly. We went through the rainy season with no leaks. Fair price for the amount of work.
Reviews From Los Angeles Window Jobs
Real experiences from customers who chose our Double Hung Window Replacement services.
“We had eight original 1950s windows that stuck so bad my wife could not open them. The crew measured on a Tuesday and installed the following week. Every sash now slides with one hand and the street noise from Moorpark dropped a lot. They hauled off the old windows and left the sills cleaner than they found them.”

Homeowner, Sherman Oaks
“Our west-facing windows had fog between the panes and the frames were soft at the sill. They showed me the rot with a photo before quoting the repair, so there was no surprise on the invoice. New low-E double hung units went in over two days. The house stays cooler in the afternoon now.”

Priya R.
Homeowner, Santa Monica
“I manage a duplex and needed six double hung windows replaced between tenants. They worked around my schedule, pulled the permit, and finished in a day and a half. Locks line up, no drafts, and the price matched the written quote exactly. I have already sent them two other owners.”

Frequently Asked Questions
Real answers to the questions we hear most often from local homeowners and property managers.
How much does Double Hung Window Replacement cost in Los Angeles?
Most single double hung units run $650 to $1,400 installed in 2026, and a full-home job of 10 to 15 windows lands between $8,000 and $18,000 depending on size, material, and glass package. Vinyl sits at the low end, fiberglass and wood at the high end. Second-story access, rot repair, and custom colors add cost. We give you a firm written number after measuring.
What is double hung window installation in Los Angeles CA?
It is the process of removing your old window and setting a new double hung unit, where both sashes slide up and down and tilt in for cleaning. In Los Angeles we typically do a retrofit install that keeps your existing frame and trim, or a full frame install when the frame is rotted. Either way, the unit gets shimmed, flashed, insulated, and sealed.

Are double hung windows good for Los Angeles homes?
Yes, and they are one of the best fits for the local climate. The tilt-in sashes let you clean second-story glass from inside, which suits the two-story homes across the Valley. With low-E glass and argon gas, they cut heat gain during inland summers and hold warmth on cool coastal nights. They also meet California energy code when properly rated.
