Trusted Window Repair Nationwide
Window repair is the work that keeps a perfectly good window from becoming a full replacement bill. A sash that will not stay open, a pane that fogs between the glass, a lock that spins without catching: each one is a small problem today and an expensive one after a winter or two. Most window repairs across the country run between $150 and $800, depending on the part that failed and how the window is built. Lightwell Windows & Doors has handled windows and doors of every type since 2010, and when you call (562) 478-8017, a live person answers. No recording, no menu, no waiting on hold while a window stands open to the weather.
We repair what can be repaired and say so plainly when it cannot. Every job is covered by the 365-Day Done Right Promise: if the finished work is not right, we make it right. And before any work begins, you get a written price. Not a range on a business card. A number on paper, with every line item spelled out. That is the Cedarwell Care Promise, and it has been our standing operating rule since day one.
A light well is what brings daylight deep into a building. That is what a working window should do for your home: open smoothly, close tight, and let the light in without letting the weather follow. Learn more about our home services, or call us directly for a free estimate.
Window Screen Repair
Window Screen Repair covers torn mesh, bent frames, and corner joints that have pulled apart after a few seasons in the sun. You need it when bugs get past a screen that looks fine from across the room, when a pet has pushed a hole through the lower corner, or when the spline has dried out and the mesh sags like a hammock. We re-mesh the existing frame whenever it is straight, because a new screen in a bent frame never sits flush. Most screen repairs run $50 to $150 per window, and a full set can often be done in a single visit.
Mesh That Fits the Window
Standard fiberglass mesh works for most rooms. Pet-resistant mesh is worth the extra few dollars on a patio-facing window, and solar mesh cuts glare on a west wall. We match the frame color and the tension so the screen looks like it came with the house.
Double Pane Window Repair
Double Pane Window Repair deals with the seal between the two sheets of glass. When that seal fails, moisture gets in, the gas fill escapes, and you see fog or a milky film that no cleaner will reach. You need it when condensation shows up between the panes, when the window feels cold to the touch in winter, or when a hairline crack runs through one layer. In most cases the frame is fine and only the sealed glass unit needs to be swapped out, which costs far less than a new window. Expect to pay between $250 and $800 per window depending on size, coating, and glass type.
Replace the Unit, Keep the Frame
We measure the existing glass unit to the sixteenth of an inch, order a matching low-E unit, and set it into your current sash. You get better insulation than the original, and the trim, paint, and exterior look stay exactly as they were.
Window Repair Company
Choosing a Window Repair Company comes down to who shows up, what they know, and whether the price on paper matches the price at the end. Lightwell Windows & Doors sends technicians who repair windows every working day, not a general handyman learning a double-hung for the first time. They carry common balances, locks, rollers, and glass stops on the truck, so many repairs finish on the first visit. If a part has to be ordered, we tell you the lead time before we leave, and we do not start dismantling anything we cannot put back together that day.
What a Good Visit Looks Like
The technician looks at the whole window, not just the complaint. A stuck sash often points to a swollen frame or a failing balance, and a draft usually has more than one source. You hear the findings, see the price in writing, and decide. Nothing gets started on an assumption.
Window Balance Repair
Window Balance Repair fixes the spring or cord system that holds a sash up once you open it. You need it when a double-hung window slams shut on its own, will not stay open without a stick propping it, or feels heavy on one side and light on the other. The balance is a hidden part, so people often assume the whole window is shot. It rarely is. We identify the balance type by the shoe and channel shape, match it to the original, and reset the sash so it travels evenly. Balance repairs typically run $150 to $400 per window.
Why Matching Matters
Balances are rated by sash weight. A spring that is too weak lets the window creep down, and one that is too strong makes it fight you on the way up. We weigh the sash or read the rating on the old part, so the new one holds the window exactly where you leave it.
Window Frame Repair
Window Frame Repair addresses the wood, vinyl, or aluminum that surrounds the glass. You need it when paint peels in sheets at the sill, when a screwdriver sinks into soft wood, or when a gap has opened between the frame and the wall. Wood rot is the most common cause, and it spreads quietly behind the trim. We cut out the damaged section, treat the surrounding wood, fill or splice with durable material, and reseal the joint so water runs away from the opening. Frame repairs commonly cost $200 to $900 depending on how far the damage has traveled.
Stop the Water First
A rotten sill is a symptom. The cause is water getting in at a failed caulk line, a missing drip edge, or a sill that no longer slopes outward. We fix the path the water takes before we rebuild anything, because a repaired frame that keeps getting wet will rot again.
Broken Window Repair
Broken Window Repair is the call you make after a baseball, a storm branch, or an attempted break-in. The first concern is safety and security, so we board up or secure the opening if we cannot replace the glass that day. Then we measure, order the right glass, remove every shard from the sash, and set the new pane with fresh glazing. Single broken panes usually cost $150 to $600 installed, and tempered or laminated glass for safety areas costs more. If the whole unit is bent or the frame is racked, we say so and quote the larger fix. See our door replacement work if the same event damaged an entry door.
Cleanup Is Part of the Job
Glass travels. We vacuum the floor, the sill, and the carpet edge, then check the surrounding area with a flashlight, since small slivers hide in places a broom never reaches.
Window Lock Repair
Window Lock Repair restores the latch that keeps a window closed and the house secure. You need it when the lock spins freely, the keeper has pulled out of the frame, or the two halves no longer meet because the sash has dropped. A window that cannot lock is an open invitation, and it also lets the sash rattle and leak air. We replace worn latches, reset keepers, and tighten sashes so the lock pulls the window snug against the weatherstrip. Most lock repairs cost $100 to $250 per window.
Security You Can Feel
A good lock draws the sash tight with a firm, solid feel when you turn it. If it feels loose or gritty, the lock is not doing its job. We test every latch on the window and leave each one working before the crew packs up.
Window Crank Repair
Window Crank Repair applies to casement and awning windows that open outward on an operator arm. You need it when the handle spins without moving the sash, when the window opens crooked, or when the folding handle has snapped off. The operator is a small gearbox, and the gears strip over years of use. We pull the cover, check the arm, track, and hinge, and replace the operator with a matching part. Crank repairs typically run $120 to $300 per window.
Clean, Lubricate, Align
Often the arm only needs cleaning and a proper dry lubricant, plus a quick alignment so it stops binding in the track. We try the least expensive correct fix first, and replace parts only when they are truly worn out.
Brands We Service
We work with CWS because their fiberglass and vinyl systems hold up under heavy sun and hard freezes, and their parts are consistent enough that repairs match the original. ES Windows makes a range of sliders and casements we know well, including their lock geometry and glazing channels. ECO Window Systems rounds out our lineup for homeowners who want solid performance at a fair mid-range price. Whether you have CWS, ES Windows, ECO Window Systems, or an older make that is no longer produced, we can usually find or fabricate a compatible part.
Signs You Need a Pro Right Now
- Fog or moisture between the panes. That means the seal has failed and the insulating gas has leaked out. The window no longer performs the way it was built to, and the glass unit usually needs to be replaced.
- The sash will not stay open. A failed balance or loose cord is the usual cause. Propping the window with a stick works until it falls, and a falling sash can break glass or hurt a hand.
- A draft you can feel with your hand. Air moving around the frame means the weatherstrip, caulk, or the frame itself has given up. Heating and cooling costs climb every month it goes unfixed.
- Soft or stained wood at the sill. If paint bubbles or a screwdriver sinks in, rot has started. Water damage behind the trim spreads faster than it looks from the inside.
- A lock that no longer catches. A window that cannot be secured is a risk to the house. The latch or the sash alignment needs attention before the next storm or the next night away.
Our Process, Step by Step
- 1
Inspect the whole window. We look at the glass, sash, frame, hardware, and the wall around it. The estimate is based on what we see, not a guess over the phone.
- 2
Written price, no surprises. You receive a line-item price before any work starts. Parts, labor, and any disposal are listed separately. Cedarwell Care Promise means the number you sign is the number you pay, with no change order unless you ask for a change yourself.
- 3
Protect the room. Drop cloths go down under the window and along the path from the door. Shoe covers go on. We ask before moving any furniture or curtains, per C.A.R.E.: Ask before we move or touch anything.
- 4
Repair and seal. We replace the failed part, square the sash, and reseal the joints with weather-rated caulk. Then we open and close the window through ten full cycles. A window that binds, squeaks, or rattles is fixed before we pack up.
- 5
Clean up and walkthrough. We clean like it is our own home, then show you how the finished window works and what the warranty covers. Then you get our number, answered by a person, 24/7.
How Much Does Window Repair Cost?
Window repair pricing across the country falls into a few clear bands. A screen repair runs $50 to $150. A lock or latch repair lands between $100 and $250, and a crank or operator repair between $120 and $300. Balance repair typically costs $150 to $400. Broken glass runs $150 to $600 for a single pane, while a sealed double pane unit replacement sits between $250 and $800. Frame repair, which depends on how much wood or material is damaged, usually costs $200 to $900. These figures are installed prices with labor and basic materials included.
The largest variables are window size, glass type, and what is hiding behind the trim once the sash comes out. Upper-floor windows, specialty shapes, and hard-to-find parts add time. The way to avoid overpaying is to get a detailed written estimate that separates parts, labor, and disposal, and then compare apples to apples. When a repair stops making sense, we will tell you honestly and point you toward patio door installation or a full unit swap. Our free estimate includes all of it, with no obligation and no pressure to sign the same day.
Where We Work

Frequently Asked Questions About Window Repair
Window repair is the work of fixing a specific failed part of a window, such as a screen, lock, balance, crank, frame section, or glass unit, instead of replacing the whole window. It keeps your existing frame, trim, and exterior look while restoring how the window opens, closes, seals, and locks. Lightwell Windows & Doors has handled windows and doors since 2010, and we put every price in writing before the first tool comes off the truck.
Most window repairs cost between $150 and $800. Screens run $50 to $150, locks $100 to $250, cranks $120 to $300, balances $150 to $400, and sealed double pane glass units $250 to $800. Frame repair ranges from $200 to $900 depending on damage. Every estimate from Lightwell Windows & Doors is free and written out line by line before any work starts.
Repair makes sense when the frame is sound and one part has failed, like a balance, lock, or glass unit. Replacement is usually cheaper over time when the frame is rotted through, the sash is warped, or several parts have failed at once. We tell you which one fits your window and put that recommendation in writing.
Yes. We know the frame geometry, balance types, and lock hardware for CWS, ES Windows, and ECO Window Systems. Manufacturer-specific knowledge matters because a sash from one maker comes apart differently than the same-size sash from another. We also repair older and unbranded windows whenever a compatible part can be found.
If a window has been broken by a storm, a break-in, or an accident, call us any hour and a live person answers. We schedule emergency board-up or glass replacement as quickly as possible because an open window is not something a family should sleep with. Our 24/7 phone line is (562) 478-8017.
Every job is covered by the 365-Day Done Right Promise: if the finished work is not right, Lightwell makes it right, no debate and no countdown. Replacement parts carry the manufacturer’s warranty, and we explain what that covers during the walkthrough before the crew leaves. If something feels off after the repair, call and a real person answers.
