Window Replacement - Written Price Before Anything Is Ordered

Trusted Window Replacement Nationwide

Window replacement means removing worn, damaged, or inefficient windows and installing new units that seal tightly, open smoothly, and hold their temperature. Most homeowners don’t realize a window has failed until the energy bill climbs or a draft starts moving the curtains on a still day. Our crews have been replacing windows under the Cedarwell Care Promise since 2010, and every job is covered by our 365-Day Done Right Promise: if the finished work isn’t right, we make it right. The written price lands in your hands before any work begins, so the number you agree to is the number you pay. Call (562) 478-8017 any hour and a live person answers, not a voicemail maze.

Energy Efficient Windows

Energy Efficient Windows are replacement units built with low-emissivity glass coatings, insulated frames, and tight seals that reduce heat transfer through the opening. You’re ready for them when your current windows fog between the panes, feel cold to the touch in winter, or let a room heat up like a greenhouse by mid-afternoon. Most energy efficient window replacements run between $450 and $1,100 per opening depending on glass package, frame material, and whether the existing frame is sound. Lightwell Windows & Doors carries CWS, ES Windows, and ECO Window Systems among our eight manufacturer lines, so the recommendation is matched to the home’s exposure, not to whatever single brand happens to be in the warehouse. A light well is what brings daylight deep into a building – that is what a well-installed window should do for your home, and an efficient one does it without dragging the electric bill along.

Glass Packages and Insulation

Double-pane glass with argon fill is the standard starting point for energy efficient replacement windows, and triple-pane makes sense in homes that face long winters or constant sun. We’ll walk you through the actual performance numbers before you choose, so the decision is about your comfort, not about upselling.

Frame material matters as much as glass. Vinyl, fiberglass, and wood each hold temperature differently, and the right choice depends on your climate and how much maintenance you’re willing to accept.

Pet-Safe Products and Installation

Where a pet-safe alternative exists for caulk, sealant, or insulation, we use it. Our technicians are background-checked, uniformed, and trained to the C.A.R.E. values: Clean up like it is our own home, Ask before moving or touching anything, Respect the family’s time and quiet hours, and Explain the price before the work. We’ll show you a photo of the clean-up before the crew leaves, with drop cloths under every work area from the first cut to the last sweep.

Window Repair

Window Repair is the service of restoring a window to proper function without necessarily replacing the entire unit – fixing sashes that stick, locks that won’t catch, balances that let the window slam, or hardware that has rusted in place. It’s the right call when the frame is still solid and the glass is intact but the window just doesn’t operate the way it should. Basic window repairs typically run between $120 and $350 per window depending on the part and the labor involved. Keith Yamada and the team at Lightwell Windows & Doors will tell you plainly when a repair makes sense and when DIY vs Professional Window Replacement: What’s Safe to Do Yourself isn’t worth the risk and replacement is the better long-term money. Our written price comes first, every time, so you’ll never approve a repair and then learn a different number later.

Hardware and Balance Systems

Old double-hung windows rely on spring balances, spiral rods, or weight-and-pulley systems that wear out over years of opening and closing. We replace the balance with the correct strength for the sash weight, so the window doesn’t slam down on small fingers or refuse to stay open. Pet hair and dust buildup inside the track is one of the most common causes of windows that stick – we’ll clean and lubricate the channel before we recommend anything more expensive.

Weatherstripping and Draft Control

Worn weatherstripping lets air move around the sash even when the window is closed, which shows up as a draft you can feel with the back of your hand on a cold morning. Replacing the weatherstripping is one of the least expensive repairs we do, usually under $200, and it can quiet a rattling window at the same time. If the draft is coming through the frame itself, that’s a sign the seal between window and wall has failed – a different repair that we’ll diagnose honestly.

Window Replacement Company

A Window Replacement Company is a contractor that removes old windows, installs new units, and stands behind the work after the crew leaves. You’re looking for one when you have multiple windows failing, visible rot around the frames, or windows so worn that repair would cost more than replacement. A full Los Angeles Window Replacement through Lightwell Windows & Doors typically runs between $600 and $1,400 per opening including the window, installation, and clean-up, with the exact figure in writing before we start. Then the 365-Day Done Right Promise covers what happens after. Your call is answered by a live person 24/7, so the company you’re working with never turns into a phone tree when a question comes up.

How We’re Different On-Site

Shoe covers and drop cloths go down on every visit, no exceptions. We ask before we move a single piece of furniture, a plant, or a kids’ toy, and we work with quiet tools during nap time whenever we know there’s a little one in the house. The C.A.R.E. values aren’t a poster in our warehouse – they’re the standard the crew is measured against on every job, including yours.

Choosing the Right Windows

We carry eight manufacturer brands, including Mr-Glass and ECO Window Systems along with six others, because different homes need different windows. A west-facing wall that takes full afternoon sun needs a different glass package than a shaded bedroom window. We’ll show you options that fit your home’s exposure and your family’s habits, then put the price in writing before anything is ordered.

Window Glass Replacement

Window Glass Replacement is the service of swapping out broken, cracked, or fogged glass panes while keeping the existing frame and sash in place. It’s the right choice when the frame is still structurally sound but the glass itself has failed – a baseball through the pane, a stress crack from settling, or a double-pane unit that has lost its seal and filled with fog. Window glass replacement typically runs between $180 and $500 per pane depending on the glass type, whether it’s safety glass, and the size of the opening. Lightwell Windows & Doors sources glass through our manufacturer partners so the replacement matches the original in thickness and tint. The written price is yours before we order a single piece of glass.

Double-Pane Fog and Seal Failure

When a double-pane window fills with haze you can’t wipe away from either side, the seal between the two panes has failed. The glass unit itself needs replacement, not the whole window, if the frame is still in good shape. This is one of the most common calls we receive, and homeowners are usually relieved to learn the fix is measured in hundreds, not thousands, when the frame is sound.

Safety Glass Requirements

Windows near doors, in bathrooms, and close to the floor are typically required to use tempered safety glass that crumbles rather than shattering into large shards. We’ll make sure any replacement glass meets the safety standard for the location, especially in homes with kids and pets who are harder on glass than anyone plans for. It’s a detail that matters after the first ball goes through the family room window.

Window Sash Replacement

Window Sash Replacement is the process of replacing the movable panel that holds the glass, rather than the entire window frame. You need it when the sash itself has rotted, warped, or been damaged but the frame surrounding it is still solid and square. Sash replacement typically costs between $250 and $700 per sash depending on the material, the hardware, and whether it’s a custom size. Lightwell Windows & Doors will always check the frame first – if it’s sound, sash replacement saves a considerable amount compared to a full-window replacement. The price is in writing before we start, and the work is covered by the 365-Day Done Right Promise afterward.

Rotted Wood Sashes

Wood sashes rot from the bottom up when condensation sits in the corner of the frame season after season. If the rot is caught before it spreads into the window frame, replacing just the sash is a clean fix. We’ll show you what we found, what we’re replacing, and what it costs before any work begins, so you’re never guessing about the line-item breakdown.

Vinyl and Composite Sashes

Vinyl sashes can warp from heat exposure over time and stop closing fully against the weatherstripping. We can order a matching replacement sash through manufacturers like ES Windows or CWS so the new panel matches the existing frames. The goal is a window that closes like it did the day it was installed, without replacing anything that doesn’t need to go.

Window Glass Repair

Window Glass Repair is the service of addressing damaged glass without necessarily replacing the pane – sealing a small crack, drilling and filling a chip, or stabilizing damage so it doesn’t spread. You need it when a stone from the mower puts a chip in the glass or a small crack appears but hasn’t yet run across the full width. Minor glass repairs typically cost between $75 and $250 per window depending on the extent of the damage and whether the repair is structural or cosmetic. Lightwell Windows & Doors will always give you a written price before touching the glass, and we’ll be honest when a repair isn’t enough and the pane needs to come out. Safety matters here, so any glass repair we do is done by a trained technician with the right tools.

Crack and Chip Stabilization

A chip in a window can sit unchanged for years or spider across the glass in a cold snap, depending on the glass and where the damage sits. We’ll assess the crack honestly and tell you whether a repair will hold or whether the pane is compromised. On tempered glass, even a small chip is usually the end of the pane – that glass is under constant tension, and the right answer is replacement, not patching.

When Repair Won’t Cut It

Cracks that reach the edge of the glass, damage in a sealed double-pane unit, or any break on tempered safety glass means replacement is the safe call. We don’t stretch a repair past what the glass can handle, because a window that fails later costs more than one that was replaced correctly the first time. Either way you’ll know the cost up front.

Window Pane Replacement

Window Pane Replacement is the service of replacing a single pane of glass within an existing window, whether it’s a broken pane in a wooden sash or a failed double-pane unit in a vinyl frame. It’s called for when one pane is broken or fogged but the sash, frame, and hardware are all still in good working order. Pane replacement runs between $150 and $450 per pane depending on glass type, size, and whether the window is single, double, or triple-pane. Lightwell Windows & Doors carries glass through our eight manufacturer partnerships, including ECO Window Systems and Mr-Glass, so the replacement matches the original’s clarity and thermal performance. The price is in writing before we order the glass, and the 365-Day Done Right Promise covers the job after we leave.

Matching the Original Glass

Glass thickness, tint, and low-emissivity coating all affect how the replacement pane looks and performs next to the original windows. We match the replacement pane to the original specifications so the window doesn’t stand out from its neighbors on the same wall. If the original glass is an older single-pane in a multi-pane home, we’ll show you the option to upgrade just that pane to insulated glass where the frame allows it.

Lead Paint and Older Frames

In homes built before the late 1970s, the frame and glazing around the glass may contain lead paint, which requires careful handling to protect kids and pets from dust. Our crews are trained in safe work practices around older windows, with drop cloths and containment used on every job. We’ll explain any special handling before we begin, so you know what to expect.

Window Seal Repair

Window Seal Repair is the service of restoring a failed weather seal around a window – the gasket or caulk line that keeps air and water from passing between the window and the frame or between panes of glass. You need it when you feel a draft around the edges, see condensation inside the glass, or notice water staining near the window corners after rain. Seal repair typically costs between $100 and $300 per window depending on whether we’re replacing the gasket, re-caulking the frame, or addressing a failed double-pane seal that requires a new glass unit. Lightwell Windows & Doors diagnoses the exact point of failure before recommending anything, so you’re not paying for a full window replacement when a $180 seal repair is the true fix. The written price is yours first, always.

Gasket and Caulk Replacement

Weather gaskets around the sash compress over time and lose their ability to block air, especially on windows that face afternoon sun. We’ll replace the gasket with the correct profile for your window and re-caulk where the frame meets the exterior wall. It’s a straightforward job that can change how a room feels in winter, and it’s usually done in an afternoon.

Failed Double-Pane Seals

When the seal between two panes of glass fails, no amount of caulking will clear the fog inside the unit – the glass pack itself must be replaced. We’ll confirm the seal failure, order a matching insulated glass unit, and install it so the window functions as it should. Homeowners are often surprised how affordable this is compared to replacing the entire window assembly.

Brands We Service

We work regularly with CWS windows and doors, and our technicians know the hardware, balance systems, and glass specifications of their product lines inside and out. If you have CWS units that need glass or a sash matched, we can source the right parts without trial and error.

ES Windows and ECO Window Systems are also lines we service often, along with Mr-Glass, and we can replace glass packs, hardware, weatherstripping, and sashes that match the original equipment. Whether you have one of these brands or any other make, we can help – and the diagnostic visit always starts with a written explanation of what we found and what it will cost to fix, before any work begins.

Signs You Need a Pro Right Now

• A window won’t open or close without real force. A stuck window is often a failed balance or a warped sash, and forcing it can crack the glass or strain the frame. It’s also a serious escape hazard in a fire, especially in a kids’ bedroom.
• Condensation or fog sits between the panes. That haze means the double-pane seal has failed and the insulating gas has leaked out. The window loses most of its thermal value, and the fix is replacing the glass pack, not wiping the glass.
• You can feel air moving around the window frame. A closed window that lets a draft through has failed weatherstripping or a broken exterior seal. This quietly pushes your heating and cooling bill higher every month.
• Water staining is spreading around the window trim. Staining means water is getting behind the frame, and that leads to rot and mold inside the wall. The longer it sits, the more expensive the repair becomes.
• The glass is cracked through or the pane is broken. A cracked pane lets in moisture, drops the window’s insulation value, and can shatter further without warning. Broken glass near kids or pets is a hazard that should be addressed promptly.

Our Process, Step by Step

1. 1
   The written estimate. We inspect every window, identify what’s failing, and put a line-item price in writing before any work begins. The number covers the full job, with no change orders added later.
2. 2
   Protection first. Drop cloths and shoe covers go down before tools come out, and we ask before moving anything in the room. Furniture near the window gets covered, and the floors stay clean throughout.
3. 3
   The replacement or repair. Our background-checked, uniformed technicians complete the work using the manufacturer’s specified methods and materials. Where a pet-safe product exists, we use it by default.
4. 4
   The clean-up and photo. We clean the work area completely, and you’ll see a photo of the finished clean-up before the crew leaves. Nothing left behind except the new window.
5. 5
   365-Day Done Right follow-through. If anything about the finished work isn’t right within a year, we make it right. No debate, no countdown – it’s the promise printed on our work.
