Pricing & Estimates
How much does window and door service cost in Los Angeles?
Window replacement in Los Angeles typically runs $750 to $1,850 per opening installed, and full door installation runs $1,400 to $4,200 depending on the door type, frame condition, and hardware. A single stuck slider or a broken sash latch usually lands between $150 and $450 for the repair visit itself. The honest answer is that price tracks the opening, not a flat rate. A 1962 ranch house in Lake Balboa with original aluminum frames and a stucco exterior is a different job than a newer Pasadena build with vinyl inserts and a clean rough opening.
We quote the same number to your face that shows up on the invoice. That’s the no-hassle upfront pricing rule we’ve operated under since 2010, and it’s why families who’ve been surprised by a bigger number at the end of a job tend to stay with us. Call (562) 478-8017 for a free estimate and a written price before anything gets touched.
Is it cheaper to repair a window or door than replace it?
Repair is cheaper when the frame is sound, the glass is intact, and the problem is a mechanism, seal, or hardware issue. Replacement wins when the frame itself is rotted, the glass has failed with visible fogging between panes, or the door has warped past the point where it will ever seal properly.
Here’s the rough line we draw with homeowners:
- Repair makes sense: single-pane condensation on the room side, a broken lock or crank, a slider that jumps the track, a hinge that’s pulling.
- Replacement makes sense: failed insulated glass (fog between the panes), water staining at the sill, a door that daylight shows through when closed, or frames that flex when you push on them.
- Worth replacing during repair: a single failed unit in a wall of five, when matching the original profile is still possible.
We’ll tell you which one you’re looking at before we quote either. That said, in older LA housing stock, the answer is often replacement because the original frames were never built to hold a modern seal.
Do you offer free estimates?
Yes. Estimates are free, and the number we give you is in writing before any work starts. We don’t do the “we’ll figure out the final number when we open the wall” approach. If something unexpected turns up once we’re in the opening – and in a 1920s Spanish Revival in Highland Park, it sometimes does – we stop, show you what we found, and get your approval on any change before continuing.
You can also look at our Window Replacement in Los Angeles page to see how pricing breaks down by opening type before you call.
Do you charge extra for the estimate visit or for measuring?
No. The estimate visit and the measurement are both included. We measure on-site because window and door dimensions are not something we trust to a homeowner’s tape measure, and a wrong size is a wrong size regardless of who wrote it down. The measurement happens as part of the estimate, at no extra cost.
Licensing, Insurance & Guarantees
Are you licensed and insured?
Yes. Lightwell Windows & Doors is fully licensed and insured, and our technicians are background-checked and uniformed so you know who is at your door before they knock. Every Lightwell location operates independently under the Cedarwell network, which means you’re dealing with a local company that carries its own coverage, not a national call center dispatching a subcontractor you’ve never met.
If you need proof of coverage before we schedule, ask. We’ll send it over.
Do you guarantee your work?
Yes. Every job is protected by the 365-Day Done Right Promise: if the finished work isn’t right, we make it right, with no debate and no countdown clock. That guarantee is stamped on every job we take, not just the straightforward ones.
The 365-Day Done Right Promise sits alongside the Cedarwell Care Promise, which covers how the work is done inside your home. Shoe covers and drop cloths on every visit. Pet-safe products wherever there’s a choice. A photo of the clean-up before the crew leaves. A written price before any work starts. These aren’t add-ons you have to ask for. They’re the standing operating rules of the company.
What should I check before hiring any window and door company in Los Angeles?
Ask for three things before you sign anything: written confirmation of license and insurance, a written price that spells out exactly what’s included, and a clear statement of what happens if the work isn’t right. A fourth question worth asking is who actually shows up at your door, because the person selling the job and the person installing it are often different companies.
Who owns Lightwell Windows & Doors?
Lightwell Windows & Doors is led by Keith Yamada, and each Lightwell location is independently owned and operated within the Cedarwell network. That matters for one practical reason: when something needs a decision, there’s a named person on the other end who answers for the work. Keith has built the LA operation around the idea that a window company should behave like a neighbor who returns calls, not a call center that reads from a script.
The company name isn’t random either. A light well is the architectural opening that pulls daylight deep into a building. That’s what a correctly installed window should do for your home, and it’s the standard we hold the install to.
Service, Scheduling & Response Times
How fast can you respond?
For standard estimates, we typically schedule within a few business days, and most installs are completed within two to three weeks of the signed quote. For urgent issues, call and we’ll tell you honestly what’s possible that day.
Here’s the part that matters more than a response-time promise: the phone is answered by a live person 24/7. If a newly installed door isn’t latching at 9 p.m. on a Sunday, you’re not leaving a voicemail and hoping someone checks it Monday. You get a human who can tell you what to try and when we’ll be there.
Do you offer emergency window and door service?
Yes, we handle urgent window and door problems, including broken glass from a break-in or a stray baseball, doors that won’t secure at night, and openings that have been compromised by wind or impact. Call (562) 478-8017 and a live person will pick up and help you figure out the right next step.
What we’ll tell you honestly: a window that’s cracked but still holding its seal in a secure frame is usually not an emergency. A door that won’t lock, or glass that’s fallen out of the frame, is. If you’re not sure which one you’re dealing with, call and describe it. We’d rather talk you out of an unnecessary emergency visit than charge you for one.
What areas do you serve?
We serve Los Angeles and the surrounding communities, including the San Fernando Valley, the South Bay, and the San Gabriel Valley. Our crews regularly work in neighborhoods like Sherman Oaks, Encino, North Hollywood, Culver City, Torrance, Pasadena, and Long Beach.
Local conditions shape the work here in ways that don’t apply in most of the country. The marine layer off Santa Monica Bay keeps coastal-facing windows wet for weeks at a time in late spring, which is hard on wood frames. Inland, the UV load in the San Fernando Valley fades vinyl and degrades weatherstripping faster than almost anywhere else in the state. In the foothill neighborhoods, we see more wind-driven debris damage, and the fire-rated glazing requirements that apply near the very high fire hazard severity zones are a real factor in what we can specify for certain homes. If you’re not sure whether your address sits in one of those zones, we’ll check.
How long does a window or door installation take?
A single door replacement usually takes one day. A whole-house window replacement depends on the count and the complexity, but a typical 8-to-12 opening job runs two to three days with a standard crew. We give you the schedule in writing with the quote so you can plan around kids, pets, and work-from-home days.
The Cedarwell Care Promise means the schedule is built around your household, not just ours. That includes quiet tools during nap time when a family asks, and it includes telling you in advance which parts of the house will be inaccessible on which day.
Window Services
Do you handle window installation?
Yes. We install new-construction windows as well as replacement units, and we carry eight manufacturer brands on hand: PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux. That range means the recommendation fits your home and your budget rather than the installer’s preferred vendor.
Because we’re not locked to a single manufacturer, the conversation stays about the opening. A wide, west-facing picture window in Woodland Hills that catches full afternoon sun needs different glass than a small bathroom window on the shaded side of a Culver City bungalow. We’ll show you the actual options and the actual prices for each.
Do you handle window replacement?
Yes. Window replacement is the core of what we do, and most of our LA work involves replacing original single-pane or early double-pane units with modern insulated glass. The job covers removal, disposal, any needed frame repair, flashing and sealing, and trim.
Installation typically follows this sequence:
- On-site measure: we confirm every opening, check for square, and photograph conditions inside the rough opening.
- Written quote: line-item pricing per opening with the glass package, frame material, and hardware spelled out.
- Order and confirmation: lead times vary by manufacturer and glass spec; we give you the date in writing.
- Install day prep: drop cloths down, furniture moved only with your say-so, shoe covers on.
- Set and seal: the unit goes in level, flashed, and sealed with pet-safe sealant where there’s a choice.
- Clean-up and walkthrough: we take a photo of the clean-up before we leave, and we walk the job with you.
That last step isn’t a formality. If anything isn’t right, the 365-Day Done Right Promise covers it, and we’d rather find it with you than have you find it a month later.
Do you handle impact windows and doors?
Yes. We install impact-rated windows and doors, and in Los Angeles this comes up for two separate reasons: homes in or near designated fire hazard severity zones, and homeowners who want the added security of laminated glass on ground-floor openings.
Impact products are built differently. The glazing is laminated so the pane holds together if it breaks rather than falling out in shards, and the frame and anchoring are rated to the same standard. We carry impact options across several of our brands, including PGT and CGI, and we’ll tell you if your address genuinely needs them or if a standard unit with upgraded glass gets you everything you were actually after.
Why do Los Angeles windows fail sooner than windows in other parts of the country?
The combination of UV intensity and coastal moisture is what does it. Inland Valley homes face sun exposure that breaks down vinyl and weatherstripping from the outside in, while coastal homes deal with persistent marine-layer dampness that works on wood frames and metal hardware. Add our famously uneven soil movement, and you get openings that shift slightly over the years, which is why a window that sealed perfectly five years ago can leak air today without anything being visibly wrong.
When we assess your home, we check the frame, the sash, the glass seal, and the surrounding wall separately, because the failure is often not where the homeowner thinks it is. If you’re ready for a professional assessment, take a look at our window replacement services and we’ll walk you through what you’re actually looking at.
Door Services
Do you handle door installation?
Yes. We install entry doors, patio sliders, French doors, and interior doors, with Therma-Tru among the brands we carry for entry systems. Doors are the opening most homeowners replace for reasons that have nothing to do with looks: they leak air, they stick in the summer, or they simply won’t lock securely anymore.
An entry door replacement is a one-day job in most cases. What changes the price is the frame condition behind the existing door. If the rough opening is sound, it’s a straightforward swap. If the sill has rotted or the framing has moved, that’s where the conversation shifts, and we’ll show you the problem before we quote the fix.
How much does a new front door cost in Los Angeles?
A standard entry door installation in Los Angeles runs $1,400 to $4,200 installed. The range is wide because it tracks material (steel, fiberglass, or wood), glass content, hardware quality, and whether the existing frame is reusable.
- Basic steel or fiberglass slab with standard hardware: lower end of the range.
- Fiberglass with decorative glass and upgraded hardware: middle to upper range.
- Wood entry, custom sizing, or a frame rebuild: upper end and above, quoted individually.
Sliding patio doors follow their own pricing, usually between $2,200 and $5,500 installed depending on width and glass package. A written quote tells you exactly which line you’re on. Call (562) 478-8017 for a free estimate.
Can you fix a door that sticks, leaks air, or won’t lock?
Yes, and most of those problems are fixable without a full replacement. A door that sticks in summer and swings free in winter is usually a hinge or strike-plate issue. Air leaking around the perimeter is usually weatherstripping. A lock that won’t engage cleanly is often a misaligned strike plate rather than a failed lock.
We’ll come out, diagnose it, and quote the repair. If the underlying frame has swelled or shifted enough that repairs would just buy you a year, we’ll say so and show you why. What we won’t do is replace a door that only needed an adjustment.
Should I repair or replace a sliding glass door?
Replace it if the rollers are shot and the track is worn through, if the glass seal has failed, or if the frame has corroded. Repair it if the door still slides and seals and the problem is limited to a roller, a latch, or a screen. Rolling hardware and latches are straightforward fixes. Once the track itself is ground down or the frame is bending, replacement becomes the cheaper long-term call because you’ll be paying for repairs every year instead of once.
Payment, Safety & Working in Your Home
What payment methods do you accept?
We accept major credit cards, debit cards, checks, and standard financing options through our financing partners. The exact financing terms depend on the project size and your credit, and we’ll go over the options in writing with your quote so there’s no ambiguity about what you’re signing up for.
One thing we don’t do is pressure you into a decision on the spot. The price doesn’t change based on how fast you say yes.
How do you protect my home during the work?
Floors get drop cloths, techs wear shoe covers, and we ask before we move or touch anything that isn’t the opening we’re working on. That’s the C in the C.A.R.E. values: clean up like it’s our own home. The A is ask before we move or touch, the R is respect the family’s time and quiet hours, and the E is explain the price before the work.
We take a photo of the clean-up before the crew leaves on every job. If you have toddlers or pets, tell us and we’ll sequence the work around nap schedules and keep pet-safe sealants and caulks in use wherever there’s an alternative. Windows and doors are a whole-house disruption for a couple of days, and we treat it that way.
Is there any safety concern I should know about with window and door work?
Yes, and it’s worth stating plainly: any work that involves removing a window or door from an upper floor, or opening a wall, carries real fall and structural risk. That’s a job for trained technicians with the right equipment and insurance, not a weekend project. Older homes can also have lead paint in the window frames and sills, which requires specific handling to keep dust out of the air your family breathes.
Our crews are background-checked, uniformed, and trained for both scenarios. We contain dust, we handle old finishes according to the rules that apply to your home’s age, and we don’t leave an opening unsecured overnight. If you ever see a contractor leaving a second-story opening unfastened, that’s your signal to stop the job.
Can I see the eight brands you carry before deciding?
Yes. We carry PGT, CGI, CWS, ES Windows, ECO Window Systems, Mr-Glass, Therma-Tru, and ViewLux, and we’ll walk you through which ones fit your openings and your budget before you commit to anything. Having eight options matters because no single manufacturer makes the best unit for every opening in every house. It means we can recommend based on your home instead of on what we happen to have in the warehouse.
Getting Started
What happens on the first call?
You describe the problem, we ask a few questions, and we schedule a free estimate if it sounds like a job we should look at in person. A live person answers at any hour, so there’s no phone tree and no callback list.
How do I know if I need a full replacement or just a repair?
If the frame is solid and the problem is mechanical or a seal, it’s usually a repair. If there’s fog between the panes, water staining, visible rot, or the frame flexes, it’s replacement. The estimate visit settles it, and the answer comes with a written price either way.
Do you work with homeowners or only with contractors?
We work primarily with homeowners. Some of our clients are repeat customers who’ve had us do a set of windows, then come back for a door two years later. That’s the pattern we’d rather have than a one-time transaction, and it’s why the 365-Day Done Right Promise exists and why the phone is always answered.
Can you match the look of the windows already on my house?
Yes, in most cases. With eight brands to draw from, we can usually match profile, color, and grid pattern closely enough that a new unit doesn’t announce itself as the odd one out. If an exact match isn’t possible because the original profile is discontinued, we’ll tell you that upfront and show you the closest option, including what it will look like next to the existing units.
