AfterWindows & Doors in North Hollywood, CA
Window installation in North Hollywood is a replacement job, not a repair job. The neighborhood’s post-WWII ranch homes and mid-century apartment buildings still carry original aluminum-frame single-pane sliders that turn the San Fernando Valley’s 105-degree summers into an indoor cooling bill and a constant draft. Sightline Windows & Doors installs dual-pane, low-SHGC replacement windows and properly sealed doors built for this specific heat profile, with a written price before any work starts. Call (509) 265-6387 to schedule a measured survey.
Why North Hollywood Homes Are Different
North Hollywood sits on the San Fernando Valley floor, a basin that traps radiant heat and runs 12 to 15 degrees hotter than coastal LA through July, August, and September. That single climate fact drives every window and door decision here. Homes built between the late 1940s and early 1970s, mostly wood-frame stucco ranch houses and dense apartment corridors, were framed for single-pane aluminum sliders with no thermal break. The rough openings around those original windows and hollow-core entry doors have spent six or seven decades flexing through triple-digit heat and cool nights, so full-frame replacement is the norm, not the exception. We rarely see an opening we can simply insert a retrofit into.
Along the NoHo Arts District stretch of Lankershim Boulevard, 1950s commercial storefronts are being converted into live/work lofts and mixed-use units. Those projects hit Title 24 energy compliance as a condition of the change-of-occupancy permit, which means oversized storefront glazing has to be rebuilt to a spec that out-of-area crews often miss on the first pass. Our surveyors measure to LADBS requirements from the first visit. No door in North Hollywood survives long with standard weatherstripping, either. The indoor-outdoor temperature differential through summer stresses door seals faster here than almost anywhere else in Los Angeles. The right spec, written down before the job starts, is the only way to avoid a second trip.
Our Main North Hollywood Services
Two services carry most of the call volume in North Hollywood: full door replacement for deteriorated original entries, and window replacement for the single-pane aluminum sliders that dominate the housing stock. Each has its own dedicated North Hollywood page with detailed pricing and job scope.
Door Installation in North Hollywood
Original hollow-core entry doors on North Hollywood ranch homes and mid-century apartments have absorbed decades of direct valley sun. Frames have shifted, weatherstripping has flattened, and the rough opening often needs rebuilding before a new door can go in. We replace the full rough opening, set a properly sealed door with correct reveal dimensions, and leave a documented photo record of the shim points, flashing, and finish. Details on scoping and pricing live on the dedicated page. Door Installation in North Hollywood
Window Replacement in North Hollywood
The original single-pane aluminum sliders throughout North Hollywood’s 1950s and 1960s housing stock were never designed for this heat. Frames sweat in winter, bake in summer, and leak conditioned air around failing seals. Replacement here means full-frame work in most cases, removing the old window to the rough opening and rebuilding the water management layer before the new unit goes in. That page carries the sub-job breakdown and measured figures. Window Replacement in North Hollywood

BeforeAfterWindow Installation in North Hollywood
Window installation in North Hollywood means removing original single-pane aluminum sliders from wood-frame stucco openings and rebuilding the rough opening to hold a dual-pane unit with the right SHGC for the valley floor. Most homes here were built between 1949 and 1972, and the windows that came with them are now the biggest energy liability in the house. A measured survey comes first, and the written price you receive is based on that same document, never on a guess. This is the core of our Window Installation work.
Single & Double Hung Windows
Signs you need it
Sashes that won’t stay up, visible daylight at the meeting rail, or painted-shut tracks on original wood or aluminum hung windows.
What it costs in North Hollywood
Single and double hung replacements typically run $540-$1,850 per window in North Hollywood, depending on size and glass spec; full-frame replacement on older openings runs higher than inserts.
How we do it
We measure the rough opening, remove the old sashes and frame to the studs when needed, rebuild the water management layer, set the new hung unit square, and document the full install with photos.
Horizontal Roller Windows
Signs you need it
Rollers that grind or bind, tracks that bow, or drafts coming through the meeting stile on the horizontal sliders common across North Hollywood ranch homes.
What it costs in North Hollywood
Horizontal roller window replacement in North Hollywood runs $420-$1,550 per unit, with the higher end covering full-frame work on deteriorated late-1940s rough openings.
How we do it
We remove the old sliding panel and fixed panel, inspect the rough opening for rot or flex, rebuild the framing where needed, and install the new roller unit with proper drainage and flashing.
Casement Windows
Signs you need it
Crank mechanisms that slip, frames that rack out of square, or glass that rattles in the sash on older casement units.
What it costs in North Hollywood
Casement window replacement in North Hollywood ranges $640-$2,100 per window, with the top end reserved for oversized openings and low-SHGC glazing packages.
How we do it
We square the rough opening, set the new casement with structural screws at the hinge points, apply flashing tape at the sill and jambs, and test crank travel before finishing.
What Window Installation Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Single hung window replacement | $540-$1,850 |
| Horizontal roller (slider) replacement | $420-$1,550 |
| Casement window replacement | $640-$2,100 |
Do I need full-frame replacement or an insert in North Hollywood?
Most North Hollywood homes need full-frame. The original rough openings on 1950s and 1960s stucco homes have flexed and rotted at the sill, and inserts only work when the existing frame is square, dry, and structurally sound. We confirm on the measured survey. Call (509) 265-6387 for a written assessment.
How long does window installation take in North Hollywood?
Most single-opening replacements finish in one day. A full house of 10 to 14 windows typically takes three to five working days depending on stucco repair and full-frame count. Your written quote includes the schedule, not just the price.
Impact Windows & Doors in North Hollywood
Impact windows and doors in North Hollywood are not a coastal-only product. The valley’s sustained triple-digit heat puts the same one-two on glass as a wind event: radiant load on the pane and pressure on the frame from thermal expansion. For homeowners here, impact-rated glass is also a security and noise decision, and the thick laminated interlayer that stops debris also cuts Lankershim Boulevard traffic noise inside the living room. Our Impact Windows & Doors spec starts with the measured survey and the written price from that same document.
Impact-Resistant Windows
Signs you need it
West-facing windows that radiate heat into the room, recurring glass break-ins on ground-floor units, or a desire for laminated noise reduction on busy streets.
What it costs in North Hollywood
Impact-resistant windows in North Hollywood run $1,100-$3,400 per window depending on size and design pressure rating.
How we do it
We measure the opening, specify the correct design pressure for the wall’s exposure, install the laminated unit into a rebuilt rough opening, and torque every anchor to manufacturer spec.
Horizontal Roller & Sliding Impact Windows
Signs you need it
Original aluminum horizontal sliders that bow under hand pressure or carry single-pane glass on a ground-floor apartment along a main corridor.
What it costs in North Hollywood
Impact-rated horizontal roller and sliding windows in North Hollywood run $1,250-$3,600 per unit, with the upper range covering oversized multi-lite assemblies.
How we do it
We remove the old slider to the rough opening, rebuild the sill with proper drainage, set the new impact-rated roller with structural fasteners, and document the anchor points in the photo record.
What Impact Windows & Doors Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Impact-resistant windows | $1,100-$3,400 |
| Horizontal roller & sliding impact windows | $1,250-$3,600 |
| Impact French patio doors | $5,400-$11,200 |
Do impact windows help with North Hollywood heat?
Yes, but only when the glazing spec pairs the impact interlayer with low-SHGC glass. The laminated layer itself is not an energy coating. We specify the combination so you get impact protection plus solar control. Call (509) 265-6387 to review the spec.
Are impact windows required in North Hollywood?
Not by city code for standard single-family homes, but many insurers, landlords, and NoHo Arts District mixed-use conversions require or reward them. Title 24 compliance on change-of-occupancy permits often pushes the same direction. We can help you decide with the measured survey in hand.
Energy-Efficient Windows in North Hollywood
Energy-efficient windows in North Hollywood are the single highest-ROI upgrade for a home that spends July and August fighting 100-to-108-degree basin heat. The original single-pane aluminum sliders throughout this neighborhood have U-factors and SHGC numbers that make air conditioning run constantly. Replacing them with dual-pane, low-E, low-SHGC units changes the room temperature before the thermostat does. Our Energy-Efficient Windows work always starts with the frame and glazing numbers in writing.
Low-E & Argon Gas Glass
Signs you need it
Rooms that stay hot with AC running, glass that feels warm to the touch at 4 p.m., or window condensation between panes on older dual-pane attempts.
What it costs in North Hollywood
Low-E with argon gas glass runs $800-$2,000 per window in North Hollywood, depending on glass area and the frame system specified for the opening.
How we do it
We spec the correct low-E coating for the window’s exposure, order the insulated glass unit with argon fill, and install it into a rebuilt or verified frame with proper thermal isolation.
UV-Blocking & Fade Protection
Signs you need it
Hardwood floors, rugs, or furniture showing uneven color loss near south and west windows, especially in the flat, exposed ranch homes common to North Hollywood.
What it costs in North Hollywood
UV-blocking window packages in North Hollywood run $850-$2,200 per window depending on glass size and coating layers; the films and coatings add a line item, not a mystery markup.
How we do it
We use a low-E coating tuned to block the UV band without darkening visible light, install the unit in the rebuilt opening, and confirm light transmittance and SHGC from the spec sheet.
What Energy-Efficient Windows Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Low-E & argon gas glass | $800-$2,000 |
| ENERGY STAR replacement windows | $750-$1,900 |
| UV-blocking & fade protection | $850-$2,200 |
What SHGC should I target for North Hollywood?
Look for an SHGC of 0.25 or lower on west-facing windows, and no higher than 0.30 anywhere in the valley floor. U-factor matters less here than solar heat gain, but 0.30 or lower is a reasonable target for the frame and glass assembly.
Will new windows really lower my AC bill in North Hollywood?
Yes, and the biggest variable is the old window you are replacing. Original single-pane aluminum on a west wall is close to having no window at all. A written quote from Sightline includes the spec on the glass, so you can compare what you are buying.
Sliding & Patio Doors in North Hollywood
Sliding and patio doors in North Hollywood take a beating that sliding doors in Burbank or Studio City do not: the valley floor heat loads the frame and glass every afternoon while the overnight cool flexes the stucco wall around it. The result is rollers that bind, tracks that sag, and weatherstripping that loses its seal in one or two summers. We measure the full opening, survey what the frame has done over the decades, and install a replacement door that opens and seals the way the original never did. This is our Sliding & Patio Doors work.
Patio Doors
Signs you need it
Sticking or lifting doors, condensation fog between panes, visible light leaking around the perimeter, or a threshold that rocks under foot traffic.
What it costs in North Hollywood
Patio door replacement in North Hollywood runs $2,500-$5,800 per opening, with full-frame work on post-WWII rough openings commanding the higher end.
How we do it
We remove the old door to the rough opening, rebuild the sill and jambs with new waterproofing, set the replacement door with a measured margin around every side, and flash the exterior before trim goes back on.
Impact Sliding Glass Doors
Signs you need it
Ground-floor units where the original sliding door is single-pane, faces a street or alley, or lets afternoon heat through an unprotected west-facing opening.
What it costs in North Hollywood
Impact sliding glass doors in North Hollywood run $4,200-$9,300 per opening depending on width, height, and design pressure rating.
How we do it
We measure the opening, specify the impact-rated door for the required design pressure, rebuild the rough opening and sill, and set the new door with structural anchors at the specified intervals.
What Sliding & Patio Doors Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Patio doors | $2,500-$5,800 |
| Impact sliding glass doors | $4,200-$9,300 |
| Screen door installation | $250-$650 |
Why do sliding doors fail so fast in North Hollywood?
The combination of sustained 100-degree days and cool valley nights flexes the frame and wall at different rates. The seals and rollers give out long before the glass does. Replacing the door as a complete assembly, not just the track, is the only fix that lasts here.
Can I keep my existing sliding door frame?
Rarely in North Hollywood. Most original frames in 1950s and 1960s stucco homes have shifted out of square, and the rough opening usually needs rebuilding before a new door can seat correctly. We verify on the measured survey, not after demolition.
Impact Garage Doors in North Hollywood
Impact garage doors in North Hollywood occupy a strange middle ground. The valley does not get hurricane-force winds, but the same laminated construction that stops debris also resists the daily thermal flex that eventually racks an uninsulated steel door out of square. For homeowners here, impact-rated garage doors are more about structural stability and noise than wind code, except in the NoHo Arts District conversions where LADBS wind-load compliance can become a permit condition. Our Impact Garage Doors work is specified from the measured opening and written into the same document as the price.
Hurricane-Rated Garage Doors
Signs you need it
A garage door that rattles in the wind, panels that flex under hand pressure, or a building conversion where the permit package calls for wind-load-rated assemblies.
What it costs in North Hollywood
Hurricane-rated garage doors in North Hollywood run $3,800-$8,500 depending on width, height, and the design pressure rating specified.
How we do it
We measure the garage opening, confirm the required wind-load rating with the project’s structural drawings when applicable, and install the rated door with reinforced tracks, struts, and fasteners.
Garage Door Replacement
Signs you need it
Bottom panels that bow from heat, tracks that pull from the wall, original wood doors with swollen frames, or a door that no longer balances and holds position.
What it costs in North Hollywood
Garage door replacement in North Hollywood runs $2,200-$5,500 per door, with full-frame and track replacement on the higher end.
How we do it
We verify the rough opening, remove the old door and tracks, install the new assembly with balanced springs, and document the completed hardware and safety sensors with photos.
What Impact Garage Doors Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Hurricane-rated garage doors | $3,800-$8,500 |
| Garage door replacement | $2,200-$5,500 |
| Wind-load code compliance retrofit | $1,500-$3,800 |
Do I need an impact garage door in North Hollywood?
Only when your specific project or insurer requires it. What most North Hollywood garages actually need is a properly insulated, structurally reinforced door that holds its shape through valley heat cycles, which is a different spec. We can price both from one measured survey.
Will a new garage door help with an attached garage in North Hollywood heat?
Yes, and the biggest gain is insulation and air sealing, not the impact rating itself. A garage door that seals the opening cuts the heat that migrates into adjoining rooms. We include the thermal specs in the written quote.
Custom & Geometric Windows in North Hollywood
Custom and geometric windows in North Hollywood come up in two settings: original mid-century homes where a curved or angled opening was part of the design, and the live/work conversions along Lankershim where the original storefront glazing never matched standard window sizes. The valley’s heat means any custom shape still has to carry the right glazing spec, and a curved or oversized unit loses its thermal performance if the frame is not built to hold the glass correctly. Our Custom & Geometric Windows work starts with a measured survey that captures the exact sightline and radius, then a written price from that same drawing.
Arched & Curved Windows
Signs you need it
Original arched or radius windows with failing glazing, cracked trim, or broken seals that no standard-size replacement can fill.
What it costs in North Hollywood
Arched and curved window units in North Hollywood run $1,500-$4,200 per opening depending on radius, size, and glazing package.
How we do it
We take a radius template from the existing opening, order the curved frame and glass to that exact profile, rebuild the rough opening with matching curvature, and install the unit with the same flashing protocol as any window on the house.
Oversized Openings
Signs you need it
Live/work conversions with storefront glazing, original picture windows wider than 6 feet, or openings where the header has sagged and the glass no longer sits square.
What it costs in North Hollywood
Oversized window openings in North Hollywood run $2,800-$8,500 per opening depending on glass area, structural framing, and Title 24 compliance work.
How we do it
We measure the full rough opening and header condition, engineer any structural corrections, order the oversized unit as a complete assembly, and install it with anchor patterns specified for the glass weight.
What Custom & Geometric Windows Costs in North Hollywood
| Item | Typical range in North Hollywood |
|---|---|
| Arched & curved windows | $1,500-$4,200 |
| Oversized openings | $2,800-$8,500 |
| Custom impact windows | $1,800-$5,600 |
Can you match an existing curved window in a mid-century North Hollywood home?
Yes, we take a template from the original opening and order to that exact radius. The glazing spec can be updated to modern low-E without changing the sightline. The written quote includes the radius measurement, so there is no guesswork later.
Do custom windows trigger Title 24 in North Hollywood?
On single-family replacements, no, as long as the opening size does not change. On live/work or mixed-use conversions along Lankershim, the change-of-occupancy permit often does bring Title 24 into play. We can review your permit package before you order glass.
Brands We Service in North Hollywood
We work with PGT, CGI, ES Windows, and CWS across most North Hollywood jobs, with product lines specified by what the opening requires rather than what’s in stock. Parts for these brands are stocked locally, and turnaround on standard sizes is typically fast. See our brands for the full line card.
Pricing for Windows & Doors in North Hollywood, CA
| Service | Typical range in North Hollywood |
|---|---|
| Window installation | $420-$2,100 per window |
| Impact windows | $1,100-$3,600 per window |
| Energy-efficient windows | $750-$2,200 per window |
| Patio doors | $2,500-$5,800 per door |

| Impact garage doors | $3,800-$8,500 per door |
| Custom & geometric windows | $1,500-$8,500 per opening |
North Hollywood prices push toward the high end of these ranges when the original rough opening needs full-frame rebuilding, which is most of the time in this housing stock. The other driver is glazing spec: low-SHGC glass and impact-rated laminated units add material cost, not hidden margin. Every Sightline quote is written before any work starts, and the price on that document is the price you pay.

FAQs About Windows & Doors in North Hollywood
Most like-for-like window and door replacements in single-family homes do not require a city permit. Change-of-occupancy conversions, oversized openings, and structural repairs to headers do. We review your specific scope during the measured survey and flag anything that needs LADBS sign-off before work begins.
We typically get a surveyor out within a few business days. The survey is where every North Hollywood job starts because the written price cannot exist before the measurements are taken. Call (509) 265-6387 and a live person will schedule you, not a callback queue.
No. The measured survey and the written quote are the same document under the Haven Standard. If the survey missed something, we catch it before the quote is issued, not after the wall is open. You will not see a change order from us on a properly surveyed North Hollywood opening.
