Casement Windows

Casement Windows open outward on a side hinge, usually with a crank, and they’re one of the best choices for Pasadena homeowners who want maximum airflow and a clean, unobstructed view. Because they seal tightly against the frame when closed, casement windows also perform well in older homes where drafts have been a problem, and they’re common in Spanish Colonial and Mediterranean styles you see throughout San Marino and La Cañada Flintridge. Lightwell Windows Pasadena installs casement windows in most Pasadena homes for $600 to $1,500 per opening, depending on size, frame material, and whether the existing opening needs repair before the new unit goes in.

Best Rooms for Casement Placement

Kitchens and bathrooms benefit most from Awning & Hopper Windows or casement windows because the crank mechanism makes them easy to open over a counter or sink. They also work well in bedrooms where you want to catch the evening breeze coming down from the San Gabriel Mountains without leaving a large open sash for pets or kids to push on.

What Installation Covers

Every casement install includes removal of the old unit, inspection of the rough opening for rot or termite damage, new flashing and insulation, and a final seal that keeps the window watertight. We use pet-safe sealants where alternatives exist, and the crew lays down drop cloths before any tool comes out of the truck.

Double Hung Windows

Double Hung Windows have two operable sashes that slide up and down, which makes them a natural fit for the two-story Colonials and traditional homes you see throughout Madison Heights and the Caltech neighborhood. They’re also one of the easier styles to clean because both sashes tilt inward, so a second-floor window doesn’t require a ladder from the outside. In Pasadena, double hung installation typically runs $500 to $1,300 per window, with the final number driven by frame material, glass package, and whether we’re replacing a same-size unit or resizing an opening.

Why Homeowners Choose Double Hung

Parents often pick double hung windows for kids’ bedrooms because you can open the top sash for airflow while keeping the bottom sash closed, which is a real concern in homes with young children near Pasadena’s tree-lined streets. The tilt-in cleaning feature is another reason: no more leaning out an upstairs window with a squeegee.

Frame Material Notes

We install double hung units in vinyl, fiberglass, and wood-clad options. Wood-clad interiors are popular in Pasadena’s older homes where the interior trim needs to match existing millwork, while vinyl keeps the price lower and requires almost no maintenance down the line.

Vinyl Windows

Vinyl Windows are the most common choice for Pasadena homeowners who want solid thermal performance at a budget-minded price. They’re made from extruded PVC with welded corners and multi-chambered frames that resist heat transfer, which matters during Pasadena’s long summer stretch when afternoon temperatures in the 90s and 100s hit homes in East Pasadena and Lamanda Park. Lightwell Windows Pasadena installs vinyl windows for $450 to $1,100 per opening on average, and we carry them from manufacturers including ViewLux and Mr-Glass.

Durability in a Pasadena Climate

Vinyl holds up well against the region’s dry heat and doesn’t warp or fade the way older aluminum frames do, and it never needs painting. The material is also recyclable at end of life, and it resists the UV exposure that comes with south-facing windows in homes along Colorado Boulevard.

When Vinyl Makes the Most Sense

If you’re planning to stay in the home for ten or more years and want a low-maintenance window that keeps the AC bill down, vinyl is hard to beat. We don’t push vinyl on homes where the architectural style calls for wood, but in many Pasadena ranches and smaller bungalows it’s the honest, practical answer.

Picture Window

Picture Window units are fixed windows that don’t open, built to frame a view and pull in as much daylight as possible. They’re popular in homes that face the San Gabriels, in living rooms in Altadena that look out over the arroyo, and in dining rooms where a table gets used every night and nobody needs the window itself to ventilate. A picture window installation in Pasadena typically costs $500 to $1,600, and the price varies most with the size of the glass unit and whether the wall framing needs reinforcement around the opening.

Where Picture Windows Shine

Homes with one striking view, a backyard garden, or a front-facing wall with good morning light are the best candidates. A light well is what brings daylight deep into a building, and that is what a well-installed picture window should do for your home: open the wall without adding a single moving part.

Pairing Picture Windows with Ventilation

Most Pasadena homeowners pair a large picture window with operable side units, usually 3-Panel Sliding (3-Lite Roller) Windows or double hungs, so the view wall still moves air when the Santa Anas pick up. We’ll walk through the layout with you before ordering, because the glass sizing has to match the wall’s structural load and the local building code for egress in the surrounding openings.

Bay Window Installation

Bay & Bow Windows change the footprint of the room, not just the glass. A bay projects outward from the wall in three angled sections, and in Pasadena it’s a common upgrade in front-facing living rooms in neighborhoods like Chapman Woods and Lower Hastings Ranch where the extra interior window seat space matters as much as the view. Bay window installation in Pasadena typically runs $1,500 to $3,500 per unit, because it involves building out the bump-out structure, reinforcing the cantilever, insulating the projection, and finishing both the interior and exterior with care.

What the Crew Protects During a Bay Install

A bay window job cuts an opening in an exterior wall, so the crew sets up dust barriers before any cutting starts, and drop cloths go down from the doorway to the work area. Shoes come off or covers go on at the door, depending on the finish on your floors, and the team follows the C.A.R.E. values on every visit: Clean up like it is our own home, Ask before we move or touch anything, Respect the family’s time and quiet hours, Explain the price before the work.

Structural Considerations in Older Pasadena Homes

Many pre-1940 homes in Pasadena have plaster walls and dimensional lumber framing, so we check the floor joists and the existing header before a bay goes in. If the cantilever needs additional support, that’s reflected in the written price before work starts, not as a surprise change order after the wall is open.

Window Contractor

A Window Contractor is the person who takes responsibility for the whole job: measuring, ordering, installing, trimming, sealing, and standing behind the result. Lightwell Windows Pasadena acts as your window contractor from the first measurement to the final walkthrough, and we carry eight manufacturer brands, including PGT and CGI, so the recommendation fits the home rather than the installer’s preferred vendor. Most window contractor work in Pasadena runs $450 to $1,800 per opening, and the written price includes labor, materials, flashing, insulation, and disposal of the old sash and frame.

When You Need a Contractor, Not Just a Handyman

If the window opening has water damage, dry rot, or sagging framing, you need a licensed window contractor, not a general handyman with a caulk gun. Pasadena’s older housing stock often hides sill damage behind the interior trim, and catching it early saves the cost of a full frame-out later.

How We Put Prices in Writing

Before any work starts, you get a line-item quote that lists the window unit, the labor, the sealants, the flashing, and any structural repair the opening needs. That’s the number on the invoice at the end. No change orders, no markups added after the crew is already on site.

Window Installers

Window Installers are the people on site doing the physical work, and the quality of an installation lives or dies with their habits: how they cut the opening, how they flash the sill, how carefully they seal the frame, and how they leave the room when the job is done. Lightwell Windows Pasadena employs background-checked, uniformed window installers who follow the C.A.R.E. values on every visit, and every one of them works under the Cedarwell Care Promise that has been in place since 2010. Window installer labor in Pasadena typically accounts for $200 to $500 of the per-window price, included in the written estimate.

What C.A.R.E. Looks Like On Site

Clean up like it is our own home, which means a photo of the clean-up before the crew leaves. Ask before we move or touch anything, because a sofa against the wall or a kid’s toy basket isn’t an obstacle, it’s your stuff. Respect the family’s time and quiet hours, so we don’t run loud tools during nap time when the homeowner asks. Explain the price before the work, so the invoice matches the quote to the dollar.

Protecting Kids, Pets, and Floors

A pet-safe caulk is used wherever a formulation exists, and the crew covers floors with drop cloths and wears shoe covers inside the house. Doors stay closed when the opening is cut so dust doesn’t drift into the nursery or the kitchen. These are small habits, but they’re the difference between a crew you recommend to your neighbor and a crew you lock the door on.

Brands We Service

Lightwell Windows Pasadena installs and services units from PGT, CGI, and CWS, three of the manufacturers most common in coastal and inland Southern California homes. PGT makes impact-rated glass systems, and we’ve replaced their units in homes across Pasadena’s foothill neighborhoods where wind-driven debris is a real concern. CGI’s aluminum and vinyl lines are familiar in mid-century homes, and CWS often shows up in custom new-construction work in Arcadia and Monrovia.

We don’t push a single brand on every job. The right window depends on the home’s age, the wall’s exposure, the family’s noise tolerance, and the budget. Whether you have PGT, CGI, CWS, or any other make, we can help you get the right replacement or new installation, with the price in writing before any work begins.

Signs You Need a Pro Right Now

• Drafts you can feel with the window closed. A closed window that lets air through means the weatherstripping or the seal has failed, and the conditioned air you paid for is leaving the house. In Pasadena’s summer, that’s a monthly utility bill that keeps climbing for no reason.
• Visible daylight around the window frame at any edge. If you can see a sliver of light where the window meets the wall, the flashing or seal has shifted. Water follows the same path light does, and a gap like that is how window leaks start.
• Condensation trapped between the glass panes. That means the insulated glass unit has lost its seal and the desiccant inside can’t do its job. The window will keep fogging, and the thermal performance is gone until the sash or glass unit is replaced.
• Sashes that stick, rattle, or won’t stay open. When a double hung sash won’t stay up or a casement crank binds, the hardware or the balance mechanism is failing. Left alone, it can slam shut on a hand, which becomes a safety issue around kids.
• Soft wood or flaking paint at the window sill. Pasadena homes with wood sills can develop dry rot where sprinkler overspray hits the exterior. Press the sill with a screwdriver; if it gives, the water damage may already extend into the rough opening behind the trim.

Our Process, Step by Step

1. 1
   The measurement visit. A uniformed technician comes to the home, walks each room with you, and measures every opening to the eighth of an inch. We check the existing frame for square and inspect the sill and surrounding wall for moisture damage before any pricing is locked.
2. 2
   The written estimate. You get a line-item price for the whole job before any work starts. It covers the window unit, labor, flashing, insulation, sealants, disposal of the old window, and any structural repair the opening needs. The number you approve is the number you pay.
3. 3
   The installation day. The crew arrives in uniform, puts down drop cloths from the entry to the work area, and covers shoes before walking on your floors. We keep the work area sealed off from the rest of the house, and we’ll match quiet tools to nap time when the homeowner asks.
4. 4
   The clean-up and photo. Every scrap of old caulk, shim, and packaging goes out with the crew. Before we leave, we take a photo of the cleaned-up room and send it to you, along with a mirror image of the work area so you can see what was moved and what was left untouched.
5. 5
   The follow-up and the Promise. If anything isn’t right in the first year, the 365-Day Done Right Promise means we make it right, no debate and no countdown. We don’t hand you a warranty packet and disappear; a real person answers the phone at (626) 628-2308 if a question comes up at 2 PM or 2 AM.
