Trusted Window Installation Nationwide
Window installation, done right, means the difference between a home that holds its temperature and one that leaks money every season. Westlight Windows & Doors has installed replacement and new-construction windows since 2009, and we carry eight manufacturer lines so the product always fits the house instead of the other way around. For a deeper look at how we approach each project, see The Complete Window Installation Guide for Los Angeles Homeowners. Most single-window replacements run $450-$1,200 installed depending on size, frame material, and glass package, and you’ll always see your written price before any work begins. If a window has failed, rotted, or simply stopped closing, call (903) 354-7134 and a live person answers, day or night. We’re the independent Kingswell location that puts every price and promise in writing first.
Casement Windows
Casement Windows are hinged on one side and crank outward, and they’re the tightest-sealing operable window you can buy. When closed, the sash presses against the frame and compresses the weatherstripping, which is why we recommend them for rooms that catch hard wind or driving rain. Westlight Windows & Doors installs casement units from brands including CWS and ES Windows, with most our Window Installation in Los Angeles casement window installations running $550-$1,300 per unit depending on size and glass. We measure, order, and install to the manufacturer’s spec, and your written price includes the full installation, cleanup, and haul-away of the old window. Nothing gets added at the door.
Hard-to-Reach Openings
Kitchens, over sinks, and second-story walls are where casements earn their keep. The crank mechanism means you can open the window full even when the sill sits well beyond arm’s reach. Our installers set the hardware so the crank operates smoothly from a standing position, and we check the sash for plumb in three directions before we call the job done.
Maximum Ventilation
Because a casement opens completely, it catches side breezes that sliding windows miss. Homeowners who want cross-ventilation in a stuffy room often pair one casement on each wall. We can order units with screens mounted inside, so the screen stays put year-round while the sash opens to the full rated width.
Double Hung Windows
Double Hung Windows have two sashes that slide vertically, and they remain one of the most requested window styles in American homes. Both halves tilt inward for cleaning, which matters on second floors where ladder work is dangerous. Westlight installs double hung units from brands such as ECO Window Systems and Mr-Glass, with typical double hung window installation priced between $400 and $1,100 per window delivered and installed. We pull permits where required, set the new frame square and level, and insulate the rough opening before the trim goes back on.
Circulation Without Drafts
You can open the top sash to let warm air escape while keeping the bottom closed against pets or small children. That simple option is why double hungs keep showing up in bedrooms and nurseries. We can spec a double hung with a tilt-in lower sash and foam-filled frame, which brings the air-infiltration rating down to a fraction of what old wood units allow.
Balanced Sash Operation
A double hung that slams shut or won’t stay open usually has a failed balance. Our installers set the sash weights or coil balances at installation so each sash opens with light finger pressure and stays where you leave it. If it doesn’t within the first year, the 365-Day Done Right Promise means we come back and correct it at no charge.
Vinyl Windows
Vinyl Windows are built from rigid PVC extrusions that never rot, never need paint, and hold their shape through decades of wet weather. The welded corners on a quality vinyl frame add strength without the maintenance wood demands. Westlight installs vinyl lines from ECO Window Systems and CWS, and most vinyl window replacements run $350-$900 per unit installed, making them the most budget-friendly option we carry. We order each unit to the exact rough opening measurement, then insulate and seal the new frame so air and water have no path through the wall.
Thermal Performance on a Budget
Vinyl’s natural insulating properties make it a sensible upgrade for a home with old aluminum frames. Many of our customers pair a vinyl frame with low-e glass, a thin coating that reflects heat back into the room in winter and out in summer. The combination usually costs less than a wood-clad equivalent while meeting the same energy-efficiency ratings.
Replacement Without Repainting
Once installed, vinyl window frames hold their color through the life of the unit. Fading resistance and impact tolerance have improved substantially in the last decade, and the lines we carry are rated for prolonged sun exposure. For homeowners tired of scraping and repainting every few summers, vinyl tends to end the cycle.
Picture Window
A Picture Window is a fixed pane with no moving parts, designed to frame an outside view without obstruction. Because it never opens, it achieves the tightest seal and the lowest air infiltration of any window type. Westlight installs picture windows as standalone units or paired with operable windows on either side, with typical picture window installation running $500-$1,500 depending on glass size and package. Larger units often call for tempered glass, and we spec that into the order when code requires it.
Framing the View Without Interruption
Living rooms and dining rooms with a good western view are where picture windows belong. Later in the day, the west light pours through a good fixed pane and fills the room without glare from sashes or screens. Our specialists will size the glass to the rough opening so the view reads continuous and clean from inside.
Careful Handling of Oversized Glass
A large picture window carries real weight, and glass that heavy needs a crew that knows how to set it without stressing the frame. Our background-checked technicians use suction cup rigs and two-person lifts on units that can’t be managed safely by one installer. We also verify the header above the rough opening before ordering, because older homes sometimes conceal undersized framing behind old windows.
Bay Window Installation
Bay Window Installation projects a room outward, adding floor space, natural light, and a deeper view. A bay is a three-unit assembly: a large center window with angled windows at each side. Westlight installs bays with a full framing, insulation, and roofing package, and a complete Window Installation in Huntington Park bay window installation typically runs $2,500-$5,500 depending on size, glass, and structural work. We price the job in writing before any work starts, including any added supports the overhang needs to satisfy local code.
Extending the Room’s Footprint
A bay window creates a usable ledge for plants, seating, or holiday decorating. The added depth changes how the room feels more than any other window style. Our installers build out the support framing, set the side windows at the specified angles, and tie the roof and skirt into the existing exterior so the bay sheds water cleanly.
Built From the Framing Up
Bay installation is structural work, not a simple sash swap. The overhang must be supported from beneath, and the correct header placement depends on the load above. Westlight’s crew inspects the existing wall framing before cutting anything, and we document the findings in the written estimate so there are no mid-job surprises about hidden rot or inadequate support.
Window Contractor
A Window Contractor is the licensed professional who measures, orders, installs, and stands behind your windows, and choosing the right one matters as much as the glass itself. Westlight Windows & Doors has operated since 2009 as an independently owned Kingswell location, which means local accountability with national buying power. We charge what we quote, show up in the window we gave, and leave the site cleaner than we found it. The Kingswell Guarantee puts those promises in writing before a single screw turns.
Written Price Before Any Work
You’ll receive a line-item estimate before we order materials or cut a single opening. That price doesn’t change when we walk in the door. If the job scope expands because of hidden damage, we show you in writing what we found, why it matters, and what the new number is before we proceed.
Follow-Through After the Install
Most window issues show up in the first year, and that’s why every job carries our 365-Day Done Right Promise. If the work isn’t right within the guarantee period, Westlight returns and corrects it at no charge. If a repair fails, a second visit is included automatically, no negotiating required.
Window Installers
Window Installers are the people who actually remove the old unit, set the new one, and seal it tight against weather. At Westlight, every installer is background-checked, uniformed, and employed by us, not subcontracted to a crew we’ll never see again. The typical full installation of one standard double hung or casement window runs $400-$1,200, and the labor is included in the written price you’ll see before committing to anything. If you’re weighing whether to tackle the job yourself, read our DIY vs Professional Window Installation: What’s Safe to Do Yourself breakdown first. We train our crews to follow the manufacturer’s installation instructions exactly, because warranty coverage depends on it.
Background-Checked Crews Only
You should know who is walking through your door. Every Westlight installer passes a background check before their first job, and they wear a company uniform so there’s no confusion. We tell you in advance who is scheduled to be at your home, and the office can verify that identity if you ask.
Clean Site, Documented Work
Installers haul away the old windows, vacuum the work area, and leave the interior the way they found it. We photograph the rough opening before the new window goes in and again after it’s sealed, so the finished work is documented rather than hidden behind trim. If something looks wrong later, we have the record to diagnose it accurately.
Brands We Service
We install and service windows from ES Windows, ECO Window Systems, Mr-Glass, and CWS, along with other lines in our eight-brand lineup. ES Windows builds strong aluminum and impact-rated units, and we order their frame systems for coastal and high-wind applications where a standard vinyl unit won’t pass code. ECO Window Systems gives us a high-quality vinyl and aluminum product line with solid thermal ratings at a fair price, and we sell a lot of their double hung and casement units.
For homeowners who want energy efficiency without giving up light, we turn to Mr-Glass or CWS. Mr-Glass carries an argon-filled, low-e product family that consistently hits the energy-efficiency numbers our customers ask about, and CWS has a broad selection of impact and non-impact windows that lets us match nearly any opening. If you have one of these brands or any other make already in the house, we can assess what’s there and tell you honestly whether it should be repaired or replaced.
Signs You Need a Pro Right Now
- Condensation between the panes. This means the gas fill has escaped and the seal has failed. The window’s insulating value is gone, and no amount of wiping the glass will fix it. Replacement is the lasting solution.
- Drafts you can feel from three feet away. When the weatherstripping or frame seal fails, outdoor air moves straight through the wall. A draft that strong costs real money in heating and cooling. A professional can tell you whether the frame, the sash, or the rough opening is the source.
- Wood rot around the window frame. Soft wood invites moisture deeper into the wall. Left alone, rot spreads behind the siding and into the framing. We open the area, remove what’s compromised, and rebuild the opening before installing the new unit.
- Windows that won’t open, close, or lock. In an emergency, an operable window is an exit. If a window sticks so badly that it can’t be opened quickly, that’s also a safety issue. We can adjust, repair, or replace the hardware so the window works as it should.
- Rising energy bills with no other explanation. Windows rarely fail loudly, but they fail gradually, and your utility bill shows it. If the house feels fine but the heating and cooling costs keep climbing, old or failing windows are a likely contributor. Replacing them brings the bills back in line.
Our Process, Step by Step
- 1
You call, a person answers. When you call (903) 354-7134, a real human picks up, 24 hours a day. We’ll ask a few questions about the window or the room it’s in, then schedule a visit that fits your calendar.
- 2
We measure and inspect. Our technician checks the existing window, the rough opening, and the wall framing around it. We look for hidden rot, undersized headers, and any code issues that should show up in the estimate rather than after the work begins.
- 3
You get a written price. We present a line-item estimate before any work starts. It includes the window, the labor, the cleanup, and any structural work we found during the inspection. If nothing changes, that’s the price.
- 4
We install on schedule. The crew arrives in the window we gave, sets up clean, and removes the old unit without tearing up your walls. We install to the manufacturer’s spec, insulate the rough opening, and seal every joint against air and water.
- 5
We hand you the guarantee and leave. You receive a written guarantee for the completed work at the job’s close. If anything goes wrong within the guarantee period, we come back and correct it at no charge, and a second visit is included automatically if the repair ever fails.
How Much Does Window Installation Cost?
Most single-window replacements run $450-$1,200 installed, depending on the frame material, glass package, and how much structural repair the opening needs. A basic vinyl double hung with standard glass often falls on the lower end around $350-$700. A large casement or a picture window with impact-rated or low-e glass tends toward $600-$1,300. Bay window installation runs $2,500-$5,500 for a complete three-unit assembly with framing, roof, and skirt. These numbers assume standard rough openings in good condition.
What drives the price: frame material (vinyl costs less than aluminum or wood-clad), glass coating (low-e and argon fill add cost but cut energy bills), window size, and whether the old opening needs reframing. The workmanship warranty, the disposal of the old unit, and the permit fees should all be included in the written estimate. The way to avoid overpaying is to require a line-item quote before work begins, and to ask what happens if hidden damage is discovered. That’s what Westlight provides automatically. Call (903) 354-7134 for a no-obligation estimate on your exact project.

Frequently Asked Questions About Window Installation
Window installation is the process of removing an old or builder-grade window and setting a new one into the opening, sealed and insulated against weather. It covers everything from simple replacements to full tear-out work that rebuilds part of the wall. Westlight has installed windows of every major type since 2009, and we handle the measuring, ordering, installation, and cleanup as one written price.
A standard single-window replacement typically takes one to three hours from arrival to cleanup. Larger projects like a bay window installation run a full day or more because of the structural framing involved. We’ll give you a clear time frame in writing before any work starts, and we show up in the window we gave.
Most single-window replacements run $450-$1,200 installed, and the most expensive part of the job is usually the window itself. Bay window installations run $2,500-$5,500 for the full assembly. You’ll receive a written price before any work begins, and we don’t revise quotes at the door. Call (903) 354-7134 for an exact quote, and estimates are free.
Yes, we install and service all four of those brands, along with the rest of our eight manufacturer lines. We order each product to your exact opening size rather than forcing one brand onto every job. If you need parts for an existing window, we can source them through the manufacturer’s channels.
Yes, our phone lines are staffed by a live person 24 hours a day, seven days a week. If a broken or failed window creates a security risk or lets water inside, call (903) 354-7134 and we’ll get a technician dispatched. We can board up a damaged opening and schedule the replacement quickly.
Every job carries the Kingswell Guarantee, which puts four promises in writing: the price before the work, a committed arrival window, a clean job site, and a written guarantee on the completed work. The 365-Day Done Right Promise means if the work isn’t right within the guarantee period, we come back and correct it at no charge. If that repair fails, a second visit is included automatically.
Clear about three feet of space inside and outside each window being replaced, and move furniture or wall art away from the work area. The installers will handle room protection and cleanup, so you don’t need to cover floors. If you have pets, we recommend keeping them in a separate room while the crew works, mostly for their comfort.
